FP8 is All You Need (Part 2): Full-FP64 3-D FFT on FP8-Generation Tensor CoresThe Integer-Epilogue Wall and the Minimal Hardware That Would Remove It
Satoshi Matsuoka
The NVIDIA Blackwell Ultra (B300) GPU cuts FP64 vector throughput while multiplying FP8 tensor throughput. After the recovery of FP64 GEMM via Ozaki Scheme II on FP…
