Cuts it back to avoid red tape
Nvidia has modified its AI H100 chip to get around export rules so it can be flogged to China as a “H800.”
The US government rolled out shedloads of red tape to prevent Nvidia from selling its A100 and H100 GPUs to Chinese clients. The rules limited GPU exports with chip-to-chip data transfer rates below 600 GBps.
With the A100, Nvidia trimmed the GPU's 600 GBps interconnect down to 400 GBps and rebranded it as the A800 to commercialise it in China. Nvidia is taking an identical approach to the H100.
According to Reuters' Chinese chip industry source, Nvidia reduced the chip-to-chip data transfer rate on the H800 to approximately half of the H100. That would leave the H800 with an interconnect restricted to 300 GBps. That's a more significant performance hit than compared to the A100 and A800, where the latter suffered from a 33 per cent lower chip-to-chip data transfer rate.
