Google TPU7x (Ironwood) Pod

A full TPU7x (Ironwood) pod is 9,216 chips in a 3D torus, the largest TPU pod Google has built. Per chip Google publishes 2,307 TFLOPS bf16 and 4,614 TFLOPS fp8, giving 21.26 EFLOPS and 42.52 EFLOPS across the pod; the fp8 total matches the 42.5 exaflops Google has stated publicly for an Ironwood pod, which independently confirms that chip count times per-chip peak is Google's own arithmetic. Memory is 9,216 x 192 GiB HBM at 7,380 GBps per chip, for 1.77 PB of HBM and 68 PB/s of aggregate memory bandwidth. Supported slice shapes go up to 8x16x16, or 2,048 chips, within the pod. No int8 figure is published. The table lists four SparseCores per chip; those are embedding-lookup dataflow processors, not weight sparsity. Google publishes no sparse figures and no pod-level power.
