Nerfed GeForce RTX 4090D for China to Launch Today
NVIDIA this October was barred by the US Federal Trade Commission from selling the GeForce RTX 4090 in the Chinese domestic market. The company scampered to create a China-specific variant of the RTX 4090 that would comply with the FTC's limits on the AI inference performance, while mostly being as fast as the regular RTX 4090 at gaming. The resulting product is the RTX 4090D. This card has significantly lower AI inference performance, probably due to a lower Tensor core count as VideoCardz reports, or a firmware based performance limiter similar to LHR (lite hashrate) GPUs during the peak of the crypto-scalping GPU shortage. This card goes on sale today. To prevent modding of this GPU back to a regular RTX 4090, it probably comes with a different device ID, and other barriers that prevent video BIOS from regular RTX 4090 from being transplanted over; and overclocking of the GPU is disabled beyond the maximum boost frequency advertised. The TGP has been lowered to 425 W, too.
