To heck with export controls! Nvidia reportedly plotting cut-down B300 for Chinese market

Nvidia is reportedly prepping a new Blackwell-based GPU for the Chinese market that'll outperform its controversial H20 accelerators.

The chip, allegedly codenamed the B30A, would be a cut-down version of the GPU giant's B300 accelerators announced at GTC in March, according to a Reuters report, citing two unnamed sources familiar with the matter.

Rather than the dual-GPU module of the B300, the B30A is said to utilize a single-die design and deliver roughly half the raw floating point performance of its full fat accelerator.

If the report is accurate, it suggests that the chip will deliver roughly 7 petaFLOPs of dense FP4 performance, 144GB of HBM3e, and 4TB/s of memory bandwidth. Normalized to dense FP8, that'd make the B30A about 7.6x faster and capable of delivering 50 percent more memory capacity than the H20. In fact, such a chip would rival Nvidia's own H100 ...
