AMD Instinct MI355X memory-bound vs compute-bound workloads
Sagot
AMD Instinct MI355X delivers 1,800 FP16 TFLOPS and 72 FP32 TFLOPS, backed by 8,000 GB/s of memory bandwidth and 288 GB of VRAM. In mixed-precision fine-tuning, those numbers typically convert to solid throughput on dense models up to several tens of billions of parameters.
For low-latency inference, real-world tokens-per-second on common large language models depends more on memory bandwidth than peak FLOPS — the 8,000 GB/s figure is the relevant ceiling for autoregressive decoding. On batched workloads like diffusion image generation, compute becomes the dominant factor again.
At $2.59 per hour on the budget-friendly cloud provider, performance-per-dollar is competitive for AI-heavy workloads.
The cheapest AMD Instinct MI355X cloud access right now is on Vultr at $2.59/hr.
