FLOPS by Precision

What actually differs

The TPU v7 is the newer part: TPU (2025) against the TPU v4's TPU (2020).

The TPU v7 carries 160 GB more memory (192 GB against 32 GB), so larger models fit on one GPU before you shard. Bandwidth is 1.2 TB/s against 7.4 TB/s, which sets the ceiling on decode speed.

Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
