SemiAnalysis TPU benchmark faces Blackwell scrutiny
Semiconductor analyst Ben Pouladian (@benitoz) scrutinized claims from SemiAnalysis asserting that Google's TPU achieves 50% better performance-per-dollar than NVIDIA hardware. Citing data from SemiAnalysis's own dashboard when accelerators run at peak capability, Pouladian argued that NVIDIA Blackwell actually leads by up to 9.7x because the comparison artificially disabled Blackwell's key architectural features.
Artificial benchmarking baselines frequently distort semiconductor economics by penalizing chips with superior hardware features under the guise of an apples-to-apples comparison. Disabling native architectural capabilities like FP4 quantization and specialized transformer engine optimizations penalizes hardware innovation and produces misleading cost-efficiency conclusions. While Google TPUs remain highly cost-effective for internal Google workloads, comparing both platforms at their best shows Blackwell delivering up to a 9.7x performance lead. NVIDIA continues to protect its moat against custom hyperscaler ASICs by coupling aggressive hardware enhancements with mature CUDA ecosystem optimizations.
