Introduction
AMD has taken a significant leap in AI training performance with the launch of its Instinct™ MI350 Series GPUs, demonstrated through the latest MLPerf™ 5.1 Training results. Marking AMD’s first public benchmark submission for AI training using these GPUs, the MI350 Series delivers remarkable generational improvements, faster convergence, and broad ecosystem adoption. These results highlight AMD’s commitment to advancing next-generation generative AI workloads with a powerful combination of hardware and optimized software.
Breakthrough Performance with MI350 Series
The MI350 Series, including the MI350X and MI355X, showcases up to 2.8X faster AI training compared to the previous MI300X generation. On the Llama 2-70B LoRA benchmark using FP8 precision, the MI355X completes training in just over 10 minutes, slashing the MI300X’s nearly 28-minute runtime. Even against the MI325X, training times are nearly halved. These gains stem from architectural improvements, high-bandwidth HBM3E memory, and AMD ROCm™ 7.1 software optimizations, which collectively boost kernel performance, communication efficiency, and energy savings.
Competitive Industry Benchmarks
The MI355X holds its ground against NVIDIA B200 and B300 GPUs in FP8-based MLPerf 5.1 Training submissions. For instance, Llama 2-70B LoRA training completed in 10.18 minutes on MI355X, closely matching NVIDIA’s averaged B200 and B300 times of 9.85 and 9.59 minutes, respectively. AMD’s focus on FP8 precision, rather than FP4, ensures high numerical stability and training accuracy, reflecting its alignment with production-ready generative AI needs. Compared to the previous MLPerf 5.0 round, MI355X delivers nearly 10% improved performance in FP8 training.
Expanding Ecosystem Participation
MLPerf 5.1 saw record-level ecosystem engagement with nine major partners — Asus, Cisco, Dell, Giga Computing, Krai, MangoBoost, MiTAC, QCT, and Supermicro — submitting for the first time on MI355X hardware. Each partner’s results landed within 1% of AMD’s own submissions, demonstrating the reliability and maturity of ROCm software and the MI355X platform. These submissions spanned high-demand workloads like Llama 2-70B LoRA fine-tuning and Llama 3.1-8B pre-training, proving consistent high-performance results across diverse real-world AI training scenarios.
ROCm™ 7.1 Software: The Performance Engine
AMD ROCm™ 7.1 software powers all MLPerf 5.1 submissions on Instinct GPUs, enabling scalable, high-throughput AI training. Optimizations across kernels, compilers, and communication layers accelerate convergence with FP8 precision while maintaining numerical stability. Enhancements in memory and bandwidth utilization support smooth scaling from single GPU to multi-node configurations. With day-zero model support for leading AI frameworks such as Llama 3.1-8B, Mistral, and SD-XL, developers can train and fine-tune next-gen models immediately, benefiting from a unified hardware-software ecosystem.
Leadership Through Generational Innovation
From the MI300X in 2023 to the MI350 Series in 2025, AMD has consistently improved compute density, memory bandwidth, and software performance with each generation. The MI350 Series demonstrates leadership in training efficiency, scalability, and ecosystem readiness, setting the stage for the upcoming MI450 Series and next-generation CDNA™ architecture in 2026. The combination of ROCm software and Instinct GPUs creates a robust platform for both AI training and inference, enabling rapid innovation in generative AI.
What Undercode Say:
The MLPerf 5.1 Training results position AMD Instinct MI350 Series GPUs as a competitive alternative in high-performance AI training, particularly for large-scale generative AI workloads. The nearly 3X generational performance improvement is significant, indicating that AMD is not only closing the gap with NVIDIA in FP8 training but also delivering efficiency gains that reduce both compute time and energy consumption. ROCm 7.1 emerges as a crucial differentiator, providing optimized kernel operations, communication efficiency, and framework support that make multi-node AI training more reliable and predictable.
The ecosystem’s response, with first-time partner submissions landing within 1% of AMD’s benchmarks, underscores the maturity of AMD’s AI platform. This level of reproducibility indicates strong hardware-software synergy, reducing deployment risks for enterprise AI workloads. FP8 focus rather than FP4 highlights AMD’s practical approach to production-ready precision, balancing speed and numerical stability.
Comparisons with NVIDIA show MI355X achieving near-parity in FP8 workloads, reflecting a shift in the competitive landscape where AMD can now be considered a viable option for large-scale AI model training. The trajectory from MI300X to MI350 Series demonstrates an effective roadmap of continuous hardware improvement, with HBM3E memory bandwidth and architectural refinements delivering tangible benefits.
Moreover, the collaboration with nine industry partners illustrates AMD’s ability to scale its ecosystem rapidly. The alignment of multi-node performance results signals that ROCm 7.1 can handle real-world workloads efficiently, from fine-tuning to pre-training, across diverse hardware configurations. The open benchmarking and reproducibility focus also provide transparency, fostering trust in AMD’s solutions.
Looking forward, the MI350 Series sets the stage for future adoption of AI workloads requiring extreme compute density and high throughput. As generative AI models grow in size and complexity, AMD’s combination of scalable hardware and optimized software could become critical for enterprises looking to optimize training times while maintaining model fidelity.
The focus on FP8 ensures that AMD remains aligned with industry-standard precision, giving developers a predictable and reliable platform for next-generation AI. Combined with the robust ecosystem participation, these benchmarks highlight AMD’s strategy of delivering not just peak performance but also sustainable, scalable, and energy-efficient solutions for AI infrastructure.
Overall, AMD’s approach reflects a mature, long-term vision for AI training — emphasizing both hardware capability and software excellence, which together create a reproducible and efficient training platform.
