SemiAnalysis: TPU v7 Ironwood beats Blackwell Ultra by 50% perf per dollar on inference
Sentdex · x · 2026-09-08
SemiAnalysis reports that on apples-to-apples InferenceX benchmarks, Google's TPU v7 Ironwood delivers 50% better performance per dollar than Nvidia's Blackwell Ultra when using the new TorchTPU inference stack.
TorchTPU brings native PyTorch support to TPUs, and with Google open-sourcing a set of Pallas inference kernels, the firm argues TPU externalization is moving full steam ahead. Sentdex quips that SemiAnalysis is like Ed Zitron, but just for Nvidia.
