There’s no shortage of AI hardware out there. But when you’re deploying massive models, accelerating inference at scale, or pushing HPC workloads to the edge—raw performance alone doesn’t cut it. You need performance that shows up in the real world, works with the infrastructure you already have, and delivers tangible ROI.

That’s exactly what the brand-new AMD Instinct™ MI350 Series GPUs were built to do. Unveiled at Advancing AI in June 2025, MI350 Series GPUs represent the latest leap forward in AI and HPC acceleration from AMD. Built for today’s most demanding compute environments—from generative AI to scientific simulation—these GPUs offer next-level performance, efficiency, and deployment flexibility you can count on from day one.

Performance Built for Real-World AI

Powered by the latest 4th Gen AMD CDNA™ architecture, the AMD Instinct™ MI350X and MI355X GPUs bring serious upgrades where it counts—throughput, memory, efficiency, and compatibility—so you can move faster, train bigger, and get more done without reinventing your data center.

The flagship AMD Instinct™ MI355X platform delivers up to 4X peak theoretical performance over the previous generation MI300X platform1, based on architectural improvements and supported precision formats.

These results demonstrate that the AMD Instinct MI355X platform not only delivers architectural and efficiency gains—it’s also a top-tier choice for customers demanding the highest throughput on today’s largest generative AI models. Whether you're deploying with vLLM, TensorRT-LLM, or SGLang, AMD Instinct MI350 Series GPUs deliver leadership results.

Better Throughput. Smarter Economics.

The MI355X GPU isn’t just about being faster, it’s about being more efficient. On Llama 3.1 405B inference in FP4, it delivers up to 40% better tokens-per-dollar than B2007. This translates directly into lower operational costs and better returns on overall investment in AI infrastructure.

Up to 40% More Tokens
If you care about cost savings, and who doesn’t, that’s a difference worth paying attention to.

Plug In and Scale

AMD Instinct™ MI350 Series GPUs are designed to drop into existing AMD platforms built on the UBB (Universal Base Board) infrastructure used for MI300 Series—no forklift upgrades or system re-architecture required. That means you can unlock next-gen performance with minimal friction, using the existing server chassis, power, and cooling infrastructure.

And when it comes to deployment, you’ve got options. AMD Instinct™ MI350X and MI355X platforms are available in both air-cooled and direct liquid-cooled versions, so you can scale based on your thermal and density goals, not your hardware limitations.

288GB of HBM3E Memory. No Compromises.

Each AMD Instinct™ MI350 Series GPU comes with 288GB of high-bandwidth HBM3E memory, enabling you to run a 520B+ parameter model on a single GPU8. That’s huge!

No model splitting, no interconnect bottlenecks, no extra layers of complexity, just faster time to results and simplified scaling.

AMD ROCm™ Software Keeps Getting Better

Software matters, and AMD ROCm™ continues to prove it. With optimized support for Flash Attention, Transformer Engine, and tuned GEMM operations, AMD ROCm™ 7 software is driving meaningful gains across the stack.

For example, when comparing AMD ROCm 6 to ROCm 7 software, the AMD Instinct™ MI300X GPU shows:

3.5X average uplift in inference performance across a suite of industry-standard AI models9
3X average uplift in training performance across commonly used AI training workloads10
