DeepSeekv4 Pro 0813 1.6T — B200 vs MI355X
Head-to-head AI inference benchmark comparison of B200 (NVIDIA Blackwell) and MI355X (AMD CDNA 4) on DeepSeekv4 Pro 0813 1.6T. Latency, throughput, and cost across LLM workloads. Use the chart controls below to switch sequences, precisions, and metrics — same interactions as the main inference chart.
AgentX replays real coding-agent sessions rather than fixed-length prompts, so context grows turn over turn and most of each request is served from cache instead of being recomputed. That turns the comparison into a systems question: KV transfer between nodes, prefix-aware routing, and cache capacity all move the curve alongside raw chip throughput. Fixed-sequence workloads stay the clean baseline for kernel and silicon performance, so the two scenarios answer different questions about the same hardware. Learn more about AgentX →
Near the low end of the 17–121 tok/s/user interactivity band, at 43 tok/s/user on DeepSeekv4 Pro 0813 1.6T: B200 runs 28897 tok/s/chip at $0.02/M tokens, MI355X runs 12701 at $0.03/M. B200 is 97% cheaper per token; B200 delivers 128% more tok/s/chip.
Setting 69 tok/s/user as the target on DeepSeekv4 Pro 0813 1.6T, B200 produces 11397 tok/s/chip ($0.04 per million tokens) and MI355X produces 8373 ($0.05). B200 is 18% cheaper per token; B200 delivers 36% more tok/s/chip.
At 95 tok/s/user interactivity on DeepSeekv4 Pro 0813 1.6T, B200 delivers 7119 tok/s/chip at $0.07 per million tokens; MI355X delivers 4878 tok/s/chip at $0.09. B200 is 27% cheaper per token; B200 delivers 46% more tok/s/chip at this point.

Note: Disaggregated inference configurations (e.g., MoRI SGLang, Dynamo TRTLLM) calculate cost per million tokens per decode chip or per prefill chip, rather than per total chip count. This makes direct token cost comparison with aggregated configs not an apples-to-apples comparison.
Note: Disaggregated inference configurations (e.g., MoRI SGLang, Dynamo TRTLLM) calculate input throughput per decode chip or per prefill chip, rather than per total chip count. This makes direct input throughput comparison with aggregated configs not an apples-to-apples comparison.

Interactivity is the rate at which a single user receives generated tokens while the model streams its answer — how quickly new words appear on screen. Higher values feel snappier; operators trade it against batch throughput.
How many total tokens (input + output) one US dollar of infrastructure spend buys, priced with the all-in hourly ownership cost of a Neocloud Giant operator. It is the reciprocal of cost per token, so higher means cheaper.
Formula: tok/$ = (total tok/s/chip × 3,600) ÷ all-in cost per chip-hour ($)
1 The ATOM engine is promising, however it has yet to serve production tokens. It is still in its infant stage.
