Common questions
Google TPU v7 (Ironwood) vs Google TPU v5p: which is faster for training?
Google TPU v7 (Ironwood) has 20.10x the dense FP16/BF16 throughput of the other (Google TPU v7 (Ironwood): 9,228 TFLOPS; Google TPU v5p: 459 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Google TPU v7 (Ironwood) vs Google TPU v5p: which has more memory?
Google TPU v7 (Ironwood) carries more HBM (Google TPU v7 (Ironwood): 192 GB HBM3e; Google TPU v5p: 95 GB HBM2e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v7 (Ironwood) vs Google TPU v5p: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Google TPU v7 (Ironwood) 13.18 (9,228 ÷ 700 W); Google TPU v5p 1.53 (459 ÷ 300 W). Google TPU v7 (Ironwood) wins at the die level; system-level efficiency also depends on cooling and interconnect.
Google TPU v7 (Ironwood) vs Google TPU v5p: which is more widely used?
Google TPU v7 (Ironwood): 0 robots and 0 data centers publicly running it. Google TPU v5p: 0 robots and 1 data center. Empty here means no operator has said publicly, not zero adoption in the market.
