AMD MI300X 192GB is a datacenter accelerator from AMD with 192 GB of VRAM and 5,300 GB/s of memory bandwidth, typically around $2.5/hr on cloud rental. ROCm; performance depends on ROCm version. It is aimed at production LLM serving.
38 models in the tokcalc catalog fit on one AMD MI300X 192GB, up to DeepSeek Coder V2 236B (MoE) (236B params) at awq4. Below that, throughput and cost per million tokens improve as the model gets smaller.
At fp8 with 8 concurrent users, 1× AMD MI300X 192GB serves 878.3 tokens/sec aggregate (73.19 tok/s per stream), with a 1.81 s time to first token. That works out to $0.7906 per 1M output tokens.
Around $2.5/hr for on-demand cloud rental (a typical 2025–2026 estimate across RunPod, Lambda, Modal, AWS, GCP and similar providers). Actual pricing varies by region, commitment, and spot availability — the Build vs Buy tab in the calculator pulls live quotes from several providers.
Memory bandwidth drives decode speed and VRAM drives capacity. AMD MI300X 192GB has 5,300 GB/s of bandwidth and 192 GB of VRAM, plus 1307 TFLOPS of dense FP16/BF16 compute. The comparison table on this page ranks every accelerator in the catalog on the same reference workload so you can see where it lands.
Pick your model, context length, and concurrency — the calculator computes the rest with the same formulas.
