| have implemented. And so, as you know, it's a long lead time to
| design hardware, so we were thinking about this years ago and
| wanted to make sure that MI350 had leadership in FP6 performance.
| So we made a decision to implement the FP6 data path at the same
| throughput as the FP4 data path. Of course, we had to take on a
| little bit more hardware in order to do that. FP6 has a few more
| bits, obviously, that's why it's called FP6. But we were able to
| do that within the area of constraints that we had in the matrix
| engine, and do that in a very power- and area-efficient way.
