Chip comparison
Google TPU v7 (Ironwood) vs Google TPU v6 (Trillium)
Side-by-side specs
Straight from each vendor's datasheet. Winner in bold: higher throughput, memory, or transistor count; lower power draw or price. Sparse (2:4) throughput roughly doubles the FP8/INT8 numbers shown.

Common questions
Google TPU v7 (Ironwood) vs Google TPU v6 (Trillium): which is faster for training?
Google TPU v7 (Ironwood) has 5.03x the dense FP8 throughput of the other (Google TPU v7 (Ironwood): 9,228 TFLOPS; Google TPU v6 (Trillium): 1,836 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 v6 (Trillium): which has more memory?
Google TPU v7 (Ironwood) carries more HBM (Google TPU v7 (Ironwood): 192 GB HBM3e; Google TPU v6 (Trillium): 32 GB HBM3). 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 v6 (Trillium): which is more power-efficient?
Dense FP8 TFLOPS per watt: Google TPU v7 (Ironwood) 13.18 (9,228 ÷ 700 W); Google TPU v6 (Trillium) 9.18 (1,836 ÷ 200 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 v6 (Trillium): which is more widely used?
Google TPU v7 (Ironwood): 0 robots and 0 data centers publicly running it. Google TPU v6 (Trillium): 0 robots and 1 data center. Empty here means no operator has said publicly, not zero adoption in the market.
