Evidence

TPU v7 Ironwood is the next iteration where Google nearly completely closes the gap to the corresponding Nvidia flagship GPU on FLOPs, memory, and bandwidth albeit with general availability 1 year later than Blackwell.

Context After

Source: SemiAnalysis

② Atomic Claim

SemiAnalysis 評估 TPUv7 Ironwood 在 FLOPs、memory、bandwidth 上接近 Nvidia 同期 flagship GPU，但 GA 約比 Blackwell 晚一年。
