Our Recommendation
There's no single winner — the right chip depends on whether you're optimizing for latency or for cost at scale. Cerebras wins decisively on single-user throughput and latency: 2,100–2,522 tokens per second on large open models, versus 50–1,038 on Nvidia systems. That makes wafer-scale the clear pick for interactive products — live code generation, voice agents, and multi-step reasoning loops where every token of delay compounds. GPUs win almost everything else: cost per token at high batched volume, the CUDA ecosystem (PyTorch, TensorRT-LLM, vLLM), the ability to train and serve on one stack, and availability across every cloud thanks to Nvidia's ~92% market share. The GPT-5.6 Sol launch on Cerebras isn't GPUs losing — it's a targeted deployment of speed where speed is the product. For most teams the answer is both: route latency-critical, interactive traffic to Cerebras and keep high-volume batch, training, and everything ecosystem-dependent on GPUs. Match the silicon to the workload, not to the benchmark headline. One correction this page needed: "GPU" is not one option. Priced per dollar rather than per rack, the accelerators inside the GPU camp diverge more than Cerebras diverges from the average GPU. Serving Kimi K3, AMD's MI355X returned 48 tokens/sec per dollar of GPU-hour against 33 on NVIDIA's B300 — the B300 wins throughput on every axis and loses the one that pays the bill, because it costs roughly 2.4x more per card. With AMD now shipping day-0 support for frontier open models, the CUDA-maturity argument is weaker than it was. If you costed this decision at NVIDIA prices, redo it: the cheaper GPU may beat both the expensive GPU and the wafer.
- Choose Cerebras (Wafer-Scale) when...
- Latency is the product: live code generation, voice agents, or reasoning UIs where users wait on every token
- You run multi-step agent loops where per-step latency compounds into a slow, costly experience
- You serve a single large open model to interactive users at batch size 1
- Instant time-to-first-token matters more than the lowest possible cost per token
- Choose GPU (Nvidia) when...
- You optimize for cost per token at high, batched volume rather than single-request speed
- You need the CUDA ecosystem: PyTorch, TensorRT-LLM, vLLM, and the widest model and tooling support
- You want to train and serve on the same hardware and stack
- You need to deploy anywhere: every major cloud, on-prem, from one GPU to thousands
