Introduction: The Number That Can Cost an Edge AI Project Millions
Choosing hardware for an edge AI deployment is often presented as a simple comparison. One vendor advertises more TOPS than another. A benchmark chart shows impressive inference speeds. A model card lists accuracy figures measured in a controlled environment. The decision appears straightforward.
In reality, it rarely is.
The accelerator selected for an edge AI product may remain inside that product for years. It can influence manufacturing costs, power consumption, thermal design, software architecture, model compatibility, maintenance requirements, and the long-term performance of the entire system. Yet one of the most important decisions in an edge AI program is still frequently made using numbers that cannot accurately predict what will happen when a real model processes real data on the actual device.
That is the problem the EdgeFirst Model Zoo is designed to address.
Instead of asking organizations to trust isolated vendor benchmarks or generic performance claims, EdgeFirst is publishing measurements from real validation sessions across multiple AI accelerators, hardware platforms, model families, and deployment formats. The objective is not simply to create another leaderboard. It is to make edge AI benchmarking reproducible, inspectable, and directly connected to the conditions under which the results were produced.
The result is a growing collection of hundreds of individual validation sessions covering popular YOLO detection and instance segmentation models across NPUs, GPUs, CPUs, and specialized AI accelerators.
And the deeper message behind the project is important.
A chip specification is not the same thing as application performance.
A TOPS number is not the same thing as real inference throughput.
And the fastest-looking accelerator on paper may not be the best platform for the model, dataset, board, thermal environment, and product that an organization is actually planning to deploy.
Summary: What the EdgeFirst Model Zoo Introduces
The EdgeFirst Model Zoo is a public collection of edge AI model repositories and validation results designed to provide a more transparent view of how computer vision models perform on real hardware.
The project currently covers four YOLO model families, including YOLOv5, YOLOv8, YOLO11, and YOLO26, with support for object detection and selected instance segmentation workloads.
Each family includes nano, small, and medium variants, with models available in formats such as ONNX FP32, INT8, and platform-specific compiled artifacts for supported accelerators.
Behind these repositories are 837 published validation sessions.
That distinction matters.
The project is not presenting seven isolated benchmark numbers and asking engineers to accept them. Instead, each validation session can provide access to the model artifact, dataset version, parameters, timing information, host configuration, and other details surrounding the measurement.
The goal is reproducibility.
Users can also install the EdgeFirst Profiler on their own supported hardware and measure their own models against their own datasets. Through EdgeFirst Studio, the same workflow used to produce the public measurements can be applied to custom deployments.
This shifts the discussion away from a generic question such as:
Which accelerator has the highest performance?
And moves it toward a much more useful engineering question:
Which accelerator delivers the best validated performance for my model, my data, and my deployment constraints?
The Problem With TOPS as a Purchasing Decision
TOPS, or trillions of operations per second, has become one of the most visible marketing measurements in the AI hardware industry.
The figure can represent real computational capability. It is not inherently meaningless.
The problem begins when it is treated as a prediction of application performance.
Peak integer throughput is generally measured under specific conditions and workloads. A real computer vision pipeline is considerably more complicated. Model architecture, tensor shapes, quantization strategy, memory bandwidth, operator support, preprocessing, postprocessing, runtime implementation, and software optimization can all influence the final result.
Two devices with similar theoretical TOPS ratings may behave very differently when running the same model.
Likewise, a lower-TOPS accelerator can sometimes outperform a higher-rated competitor for a particular workload because its compiler, memory architecture, runtime, or operator implementation is better suited to that model.
This creates a serious problem for engineering teams.
The hardware selection process can become influenced by a number that measures theoretical compute capacity rather than the actual workload the organization intends to deploy.
For a five-year product commitment, that is a significant risk.
Seven Model Repositories and Hundreds of Individual Measurements
The EdgeFirst Model Zoo currently organizes its coverage around several major YOLO repositories.
The detection models include YOLOv5, YOLOv8, YOLO11, and YOLO26.
Instance segmentation support is included for YOLOv8, YOLO11, and YOLO26.
Within those families, the project includes nano, small, and medium model variants.
The available artifacts include ONNX FP32, INT8 variants, and compiled deployment formats for the accelerators that have been validated.
The larger story, however, is the number of individual measurements.
The project contains 837 published validation sessions.
Each session represents a specific measurement rather than a single generalized benchmark result.
This approach creates a more detailed picture of edge AI performance.
Instead of saying that a model is fast on a platform, engineers can examine how a particular artifact performed under a specific configuration.
That difference can become extremely valuable when organizations are comparing hardware platforms that appear similar on specification sheets.
Real Hardware Coverage Across the Edge AI Landscape
The EdgeFirst Model Zoo includes measurements across several important edge AI platforms.
The validated platforms include the NXP i.MX 8M Plus with the VeriSilicon NPU, using TFLite INT8 and the VX delegate.
The project also includes the NXP i.MX 95 and its eIQ Neutron NPU, deployed through TFLite INT8 and the Neutron delegate.
NXP’s Ara240 discrete Neural Processing Unit is represented through its DVM deployment format and mixed INT8 and INT16 workloads.
The Raspberry Pi 5 combined with the Hailo-8L accelerator is included through HailoRT HEF artifacts.
NVIDIA’s Jetson Orin Nano is measured using TensorRT engines and FP16 execution.
Qualcomm Hexagon NPU workloads are represented through QNN EPContext or LiteRT with INT8 and INT16 execution.
Apple hardware is also included, covering the Apple Neural Engine, Metal GPU, and CPU through CoreML FP16 deployments.
The hardware coverage spans systems including NXP development boards, Toradex modules, Ezurio hardware, PHYTEC systems, Raspberry Pi 5, the Jetson Orin Nano Developer Kit, Samsung Galaxy S26 Ultra, MacBook Pro systems with M2 Max, iPhone 17 Pro, and iPhone 15 Pro.
The project also includes CUDA and multiple x86 and Arm CPU references, including Intel Xeon, Intel Core i9, AWS Graviton, and Graviton4 platforms.
This variety is important because edge AI is not a single hardware category.
A model deployed inside a smartphone does not operate under the same constraints as a model deployed on an industrial single-board computer.
A thermally constrained embedded device does not behave like a desktop workstation.
A discrete NPU does not necessarily behave like an integrated accelerator.
Comparing them requires context.
The Same Silicon Does Not Always Produce the Same Result
One of the more important observations highlighted by the EdgeFirst Model Zoo involves the NXP eIQ Neutron NPU.
The same NPU appears across multiple boards from different vendors.
At first glance, identical silicon might suggest identical performance.
Real-world measurements demonstrate why that assumption can be dangerous.
A board is not simply a container for a processor.
It contains a memory subsystem, power delivery system, thermal design, board support package, firmware configuration, storage configuration, and other components that can influence the behavior of an AI workload.
The SoC may be identical.
The environment surrounding it is not.
This means that selecting hardware based exclusively on a processor model number may overlook important differences between actual products.
The board that performs best in a short benchmark may also behave differently during sustained inference under thermal pressure.
The software stack may introduce additional differences.
For edge AI deployments, those details can matter as much as the accelerator itself.
Validation Matters More Than Marketing Claims
The central idea behind the EdgeFirst Model Zoo is that every published result should be traceable.
For example, a reference result for YOLOv8 Nano can connect a reported accuracy measurement to a specific validation session.
That session can expose the artifact used during testing.
It can identify the dataset version.
It can document the parameters involved.
It can include timing traces and machine details.
This makes it possible to investigate the result instead of simply accepting it.
For engineers, this creates an audit trail.
A performance number without context is difficult to evaluate.
A performance number connected to the exact model, dataset, runtime, device, and validation configuration becomes significantly more useful.
Reproducibility is especially important as AI hardware and software ecosystems become increasingly complex.
Compilers change.
Runtime versions change.
Kernel versions change.
Quantization pipelines change.
A benchmark that was accurate six months ago may not represent the behavior of a newer software environment.
Publishing the context surrounding a measurement helps preserve its engineering value.
The Decoder Can Change Accuracy Without Changing the Model
One of the strongest examples in the EdgeFirst Model Zoo demonstrates how deployment decisions can influence accuracy even when the model weights and hardware remain unchanged.
The article describes YOLOv8 Nano running on a Qualcomm Hexagon NPU using INT8 execution.
With one smart split-decoder approach, the model achieved 48.46% [email protected].
With a logical decoder configuration, the result dropped to 46.37% [email protected].
The silicon remained the same.
The weights remained the same.
The quantization scheme remained the same.
Yet the reported accuracy differed by more than two percentage points.
This is a critical lesson for edge AI developers.
Model conversion is not always a neutral operation.
The way a computational graph is exported, partitioned, decoded, or optimized can influence the behavior of the final deployment.
A team may incorrectly conclude that an accelerator produces poor results when the actual problem exists inside the conversion pipeline.
Another team may report impressive accuracy because its deployment path is more carefully optimized.
Without detailed validation information, those differences can remain invisible.
Why Latency Alone Cannot Predict Throughput
Another important lesson involves the relationship between inference latency and frames per second.
It is tempting to take a per-frame latency measurement and divide one second by that number.
The result appears to produce a frames-per-second estimate.
Real pipelines do not always work that way.
The EdgeFirst example involving YOLOv8 Nano on the Apple M2 Max Neural Engine illustrates the problem.
The model reportedly performed approximately 1.80 milliseconds of inference inside an end-to-end pipeline of approximately 5.26 milliseconds.
A simple division might suggest roughly 190 frames per second.
However, the measured throughput was reported at 791.
The reason is pipeline concurrency.
Different stages can process different frames simultaneously.
While one frame is running inference, another may be undergoing preprocessing or postprocessing.
The system is therefore not always waiting for an entire pipeline to finish before beginning work on the next frame.
This is an important distinction for organizations building real-time vision systems.
Latency measures how long a specific unit of work may take to travel through a process.
Throughput measures how much work the entire system can sustain.
They are related.
They are not interchangeable.
COCO Is the Benchmark, but It Is Not the Final Answer
The Model Zoo uses COCO because it is one of the most widely recognized datasets for evaluating object detection models.
Using a common dataset allows results to be compared more easily.
But COCO is not the reason organizations buy edge AI hardware.
A warehouse camera system may need to detect forklifts and safety equipment.
A medical device may need to identify specific visual patterns.
A manufacturing system may need to detect defects that do not exist in standard public datasets.
A smart retail system may have entirely different classes, camera angles, lighting conditions, and image distributions.
This is why a public benchmark can only provide part of the answer.
The most valuable measurement is the one produced using the organization’s own data.
A model that performs well on COCO may not perform well on a specialized dataset.
Likewise, an accelerator that performs exceptionally well with one model architecture may be less attractive for another.
The EdgeFirst approach encourages organizations to move beyond public benchmark scores and validate their own models against their own deployment conditions.
EdgeFirst Studio Turns Benchmarking Into a Repeatable Workflow
The Model Zoo is closely connected to EdgeFirst Studio and the EdgeFirst Profiler.
The workflow is designed to allow developers to import a dataset, train or import a model, convert it for a target platform, deploy the resulting artifact, and validate it on actual hardware.
The important part is consistency.
If the public results are generated using the same workflow available to users, the benchmark becomes a demonstration rather than an isolated internal test.
An engineering team can reproduce a public measurement.
It can also replace the public dataset with its own.
It can retrain the model.
It can compare multiple hardware targets.
And it can create a decision record based on measurements relevant to its own product.
This is potentially far more valuable than simply knowing which platform wins a generic benchmark.
The Real Question Is Which Hardware Wins Your Workload
The EdgeFirst Model Zoo makes an important argument about how organizations should approach AI hardware selection.
The wrong question is often:
Which chip is the fastest?
The better question is:
Which platform provides the best combination of accuracy, latency, throughput, power efficiency, software maturity, cost, and long-term support for the workload we are actually shipping?
There may not be a universal winner.
A smartphone workload may favor one accelerator.
An industrial vision deployment may favor another.
A low-power battery-powered device may require a completely different approach.
The best hardware decision emerges from the interaction between the model and the system.
That is why reproducible validation is so important.
YOLO11 and YOLO26 Coverage Is Still Expanding
The EdgeFirst Model Zoo also openly identifies areas where coverage is still in progress.
YOLO11 and YOLO26 workloads on the eIQ Neutron NPU are described as compiling, loading, and running on the hardware, while validation accuracy continues to be improved.
This is a useful distinction.
Successful execution does not automatically mean successful deployment.
A model may load correctly and produce outputs while still failing to meet the expected accuracy threshold.
Publishing only successful-looking benchmark numbers can hide these engineering challenges.
Acknowledging incomplete validation provides a more realistic picture of the deployment process.
As coverage expands, additional architectures can be added after they meet the validation requirements established by the project.
That approach favors verification over speed.
The Future of Edge AI Will Depend on Evidence
The edge AI industry is becoming increasingly crowded.
New NPUs, AI PCs, smartphone accelerators, embedded processors, GPUs, and specialized inference chips continue to appear.
At the same time, model architectures are evolving rapidly.
This creates an increasingly difficult environment for engineering teams.
The number of possible combinations is enormous.
A single deployment may involve multiple model versions, quantization approaches, compilers, runtimes, operating systems, board configurations, and accelerators.
Marketing specifications cannot capture all of that complexity.
Reproducible measurement can.
The EdgeFirst Model Zoo represents a broader movement toward treating AI benchmarking as an engineering artifact rather than a promotional number.
That distinction may become increasingly important as edge AI deployments move from experimentation into long-term commercial infrastructure.
What Undercode Say:
Benchmarking Should Stop Being a Marketing Exercise
The EdgeFirst Model Zoo addresses a problem that has existed in AI hardware benchmarking for years.
Vendors naturally want to present the strongest possible theoretical performance figure.
That is expected in a competitive industry.
The problem begins when organizations treat those figures as deployment guarantees.
An accelerator can advertise extraordinary computational performance while delivering disappointing results for a specific production model.
The gap between theoretical capability and application performance is where many expensive engineering mistakes begin.
Five-Year Hardware Decisions Need Five-Year Evidence
Choosing an accelerator is not like changing a cloud instance type.
Embedded hardware decisions can affect product architecture for years.
The selected silicon influences supply chains.
It affects thermal design.
It affects operating system support.
It affects available compilers and runtimes.
It can determine whether future model architectures remain deployable.
A decision with that level of long-term impact should not depend on a single TOPS number.
The Most Dangerous Benchmark Is the One You Cannot Reproduce
A benchmark may look impressive in a presentation.
But if engineers cannot determine the model version, runtime, dataset, preprocessing steps, and device configuration, the result has limited scientific value.
Reproducibility transforms a benchmark from an advertisement into evidence.
The ability to inspect a validation session creates accountability.
That is one of the strongest aspects of the EdgeFirst approach.
Silicon Is Only One Layer of the Performance Stack
The same accelerator can produce different results across different boards.
This should not be surprising.
Memory architecture matters.
Thermal conditions matter.
Driver versions matter.
Kernel versions matter.
Power limits matter.
Board support packages matter.
An AI accelerator does not exist in isolation.
It operates inside a complete computing system.
Quantization Is an Engineering Decision, Not a Checkbox
Many organizations describe INT8 conversion as though it were a simple final step.
In reality, quantization can change accuracy, compatibility, performance, and numerical behavior.
Calibration data can matter.
Operator support can matter.
Graph partitioning can matter.
The conversion pipeline itself can become a major source of deployment differences.
The Model
Accuracy Must Be Measured After Deployment
A model’s original training accuracy is not automatically its production accuracy.
The exported artifact is the version that matters.
The quantized artifact is the version that matters.
The compiled accelerator-specific artifact is the version that matters.
Production validation should focus on what actually runs on the device.
Anything else risks measuring a model that customers will never use.
FPS Can Mislead Engineering Teams
Frames per second is useful.
But it is incomplete.
A system can report high throughput while individual frames experience significant latency.
A system can also have low single-frame latency but poor sustained throughput.
Pipeline concurrency can change the relationship between these measurements.
Engineers should therefore measure both end-to-end latency and sustained throughput.
Neither number should replace the other.
Public Benchmarks Should Be Starting Points
COCO remains useful because it provides a common reference point.
However, no public dataset can represent every production environment.
The closer a validation dataset is to the real deployment environment, the more valuable the measurement becomes.
Organizations should treat public benchmarks as a screening tool.
Final hardware decisions should be based on internal workloads.
Hardware Selection Should Become an Evidence Pipeline
A mature edge AI program should define candidate hardware early.
It should run the same model across each candidate.
It should measure accuracy after conversion.
It should measure latency.
It should measure throughput.
It should measure power and thermal behavior.
It should repeat the tests after software stack changes.
The result should become an engineering record rather than a collection of screenshots.
The Best Accelerator Is Not Always the Fastest Accelerator
A platform with slightly lower raw performance may provide better documentation.
It may offer more stable software.
It may preserve higher model accuracy.
It may consume less power.
It may be easier to maintain.
It may have a longer support lifecycle.
Those factors can make it the superior production choice.
The fastest benchmark result does not always create the best product.
Transparency Could Become a Competitive Advantage
The AI industry increasingly faces questions about benchmark quality.
Organizations are beginning to demand reproducibility.
They want datasets.
They want methodology.
They want version information.
Projects that publish this information may gain more long-term trust than those relying exclusively on headline performance numbers.
Edge AI Is Becoming a Systems Engineering Discipline
The next stage of edge AI will not be defined only by larger TOPS figures.
It will be defined by the ability to connect models, compilers, accelerators, operating systems, and real-world datasets into measurable systems.
The companies that understand this transition will likely make better hardware decisions.
They will identify bottlenecks earlier.
They will avoid expensive redesigns.
And they will have stronger evidence when defending architectural decisions.
The Model Zoo Represents a Useful Direction
The most important contribution is not any individual benchmark result.
The real value is the methodology.
Publish the model.
Publish the validation context.
Publish the timing information.
Identify the hardware.
Allow others to reproduce the result.
Then let engineers compare the evidence with their own workloads.
That is a healthier direction for edge AI benchmarking.
Deep Analysis: How Engineers Should Validate an Edge AI Accelerator
Step One: Identify the Actual Target Hardware
Before comparing accelerators, collect complete platform information.
uname -a
The kernel version can influence driver compatibility and runtime behavior.
On Linux systems, engineers should also inspect processor information.
lscpu
For memory configuration, use:
free -h
Hardware selection should begin with a complete system profile.
Step Two: Monitor Sustained Thermal Behavior
Short benchmark tests may hide thermal throttling.
Monitoring temperature and frequency during sustained workloads is essential.
On supported Linux platforms:
watch -n 1 sensors
CPU frequency information can also be examined with:
cat /proc/cpuinfo | grep "MHz"
A benchmark that looks excellent for thirty seconds may behave very differently after thirty minutes.
Step Three: Record the Software Environment
AI benchmarks should record the operating system and runtime versions.
For example:
cat /etc/os-release
Python environments should also be documented:
python3 --version pip freeze > requirements.txt
Small dependency changes can alter inference behavior.
Step Four: Measure the Entire Pipeline
Do not measure only accelerator inference.
Measure preprocessing.
Measure inference.
Measure postprocessing.
Measure data transfer.
Measure the complete end-to-end path.
On Linux, high-level process behavior can be observed with:
perf stat ./your_inference_application
This helps move benchmarking beyond isolated model execution.
Step Five: Compare Accuracy After Conversion
A deployment workflow should compare the original model with the converted artifact.
For example, calculate and store validation results before and after quantization.
python validate_fp32.py python validate_int8.py
The comparison should focus on whether performance improvements introduce unacceptable accuracy degradation.
Step Six: Test Under Production-Like Load
Run repeated inference instead of relying on a single frame.
A simple workload loop can expose performance instability:
for i in {1..1000}; do ./run_inference.sh; done
The goal is not simply to find the fastest first result.
The goal is to understand sustained behavior.
Step Seven: Preserve the Evidence
Store system details with every benchmark.
uname -a > benchmark_environment.txt lscpu >> benchmark_environment.txt free -h >> benchmark_environment.txt
Record the model hash as well.
sha256sum model.onnx
This makes it easier to verify that future results were produced using the same artifact.
Step Eight: Build a Hardware Decision Matrix
The final selection should compare multiple factors.
Accuracy should be included.
Latency should be included.
Throughput should be included.
Power consumption should be included.
Thermal behavior should be included.
Software maturity should be included.
Long-term availability should be included.
The strongest engineering decision is rarely produced by optimizing only one metric.
Result One: TOPS Does Not Directly Equal Real Model Performance
✅ TOPS can represent theoretical computational throughput, but it does not independently predict application-level latency, accuracy, or throughput for every AI model and deployment pipeline.
Result Two: Identical Silicon Can Produce Different System Results
✅ The surrounding board, memory, software stack, thermal design, and runtime environment can influence measured performance even when the underlying accelerator is the same.
Result Three: Deployment Conversion Can Affect Accuracy
✅ Quantization, graph conversion, decoder design, and accelerator-specific compilation can change the behavior and measured accuracy of a deployed model compared with its original representation.
Prediction
(+1) Reproducible Benchmarking Will Become More Important in Edge AI
Edge AI vendors will face increasing pressure to publish benchmark methodology instead of relying only on theoretical TOPS figures.
More organizations will compare complete model pipelines, including preprocessing, inference, postprocessing, latency, throughput, and sustained thermal behavior.
Hardware selection will increasingly move toward workload-specific validation using proprietary datasets.
Model conversion pipelines and compiler optimization will become major competitive factors alongside raw accelerator performance.
Public, reproducible benchmark repositories could become increasingly valuable for engineering teams attempting to compare rapidly expanding AI hardware ecosystems.
Final Perspective: The Benchmark That Matters Is the One You Can Recreate
The EdgeFirst Model Zoo is ultimately built around a simple but powerful principle.
Do not choose hardware based only on what a specification sheet promises.
Do not assume that a public model card represents your deployment.
Do not assume that peak TOPS predicts real-world inference.
Measure the actual model.
Use the actual dataset.
Run it on the actual hardware.
Record the environment.
Validate the accuracy after conversion.
Measure the complete pipeline.
Then make the decision.
For edge AI, that approach may be slower at the beginning.
But compared with discovering a performance or accuracy problem after hardware has been selected and products have already entered development, it may be dramatically cheaper in the end.
The future of edge AI benchmarking should not belong to the loudest number on a presentation slide.
It should belong to the measurement that engineers can inspect, reproduce, challenge, and verify.
That is the real value behind the EdgeFirst Model Zoo.
