Catalog listings, not live prices.

These averages are of every tracked catalog listing, including spot, reserved, out-of-stock and older rows. They do not measure live on-demand prices or availability (the daily price history table above does that) and cannot establish savings against the current offers. Each day averages its recorded catalog snapshots; the median gives each day equal weight. Missing days are excluded.

Strengths & Limitations

Advantages
  • Exceptional 288 GB HBM3E memory for massive datasets and LLMs
  • Industry-leading 8 TB/s bandwidth reduces bottlenecks in inference
  • Up to 35x inference performance gains over prior generations in optimized workloads
  • Power-efficient design with strong FP64 for HPC
  • Growing ROCm ecosystem with open-source advantages
Limitations
  • Not yet available (production expected Q4 2025)
  • ROCm software stack less mature than NVIDIA CUDA
  • Limited initial cloud provider support and benchmarks
  • Potential optimization gaps for non-AMD-tuned frameworks
  • Higher power draw (1,000W+ TDP) requires robust cooling

Top Use Cases

Trillion-Parameter LLM Inference

Massive memory and FP8 throughput enable low-latency serving of models like Llama 405B or GPT-4 scale without sharding.

Exascale AI Training

High tensor performance and bandwidth accelerate multi-trillion parameter training runs in distributed setups.

HPC and Scientific Simulations

Superior FP64/FP32 capabilities for climate modeling, drug discovery, and physics simulations.

Real-World Benchmark

Projected MLPerf Inference v5.0 (Llama 3.1 405B)
Anticipated 3.5-4x performance over MI300X; leadership in tokens/second with 50%+ better throughput-per-dollar vs. NVIDIA H100.
