TPU7x (Ironwood) supported configurations¶
The slice shapes you can request for TPU7x (Ironwood), and how many chips and hosts each uses.
Slice shapes¶
Note: A slice shape gives the number of chips along each dimension of the interconnect. A 2D shape is written AxB and a 3D shape AxBxC. Multiply the dimensions to get the number of chips in the slice.

Shapes also follow the general form AxBxC, where each dimension is a multiple of 4, up to 9216 chips. Every shape uses the tpu7x-standard-4t machine type. Slices larger than 2048 chips require contacting your account team.
