As expected, the new version of the NVIDIA 4090 graphics card is now available in China, a graphics card that fills the void that this manufacturer was forced to leave after the ban by the United States Federal Trade Commission last October .
The US Federal Trade Commission has banned NVIDIA from selling the RTX 4090 and other artificial intelligence GPUs, forcing the manufacturer to offer a version that meets the minimum requirements required by Joe Biden’s government to sell in this Asian region. country.
NVIDIA, faced with a similar problem months ago, had been working for some time on a new version of the RTX 4090 to cover another possible ban, announcing the RTX 4090D, a new model in this range that since December 28 It is now available in China. Almost all the basic specifications of this new model were known, but the specifications were missing, specifications that with its launch are already available and, as expected, are a little lighter than the version available in the rest of the countries.
RTX 4090D specifications
As expected, language inference performance in deep learning models is lower, in order to comply with the limitations of the United States Federal Trade Commission and different measures have been added to prevent users from modifying their operation to get the same performance as the RTX 4090 version via firmware and driver. Additionally, it has an ASIC code and device ID to avoid messing with the BIOS and fooling the computer.
The silicon core used is the 5nm AD102 with 72 TPC. The RTX 4090 version available outside China has 64 TPCs enabled while the D version of the RTX 4090 only has 57 TPCs. This assumes a reduction of CUDA, Tensor and RT cores which, logically, affects its performance.
As for the CUDA cores of the RTX 4090D, it has 14,592 compared to 16,384 of the RTX 4090 version. As for the Tensor cores, the version available exclusively for China has 456 cores, compared to 512 that the original RTX 4090 has. . As for the RT cores, responsible for ray tracing, the 4090D version has 114 cores compared to 128 in the original model.
The lower power of this version for China also results in a reduced consumption. The TGP of this version is 425W compared to the 450W of the global version of the RTX 4090. The last difference is found in the 12VHPWR adaptersince the version is 3x 8 pin while the global version is 4x 8 pin.
This is where the differences between the original version of the RTX 4090 and the version specially designed for China at reduced power end. The boost clock frequency is 2.52 GHZ on both models. The GDDRX6 memory is 26 GB and has a bandwidth of 1008 GB/s.
Regarding the price, the new RTX 4090D has exactly the same starting price as the original version when it arrived in this market, which is 12,999 yuan.
