Nvidia released an anti-sanction RTX 4090D video card

The release of each new Nvidia video card always becomes a big event for everyone involved. Even if the company does not present a new generation, but simply improves the previous one, releasing a modification marked Super. So that’s the way out GeForce RTX 4090D could not go unnoticed either. Now the main thing is to understand what it is, how it differs from the classic one RTX 4090 and whether it is worth pursuing.

Usually, new video cards are always better than the previous ones. Example, RTX 4070 Super was better than the usual 4070and 4070 Ti Super – Better than 4070 Ti.

Nvidia, at least a little, pumped them up, adding fresh modifications of computing cores, increasing the clock frequency, and for some, the amount of video memory. Therefore, users naturally expected the same from the RTX 4090D, but Nvidia did not plan an upgrade anyway cool video card. The purpose of the company was completely different.

Comparison of RTX 4090 and RTX 4090D video cards

The primary reason Nvidia ventured out release GeForce RTX 4090D was the need to comply with sanctions. But not anti-Russian, as it might seem at first glance, but anti-Chinese.

Existing restrictions prevent American companies from supplying high-power graphics accelerators to the PRC, as they are actively used to build the country’s own AI infrastructure.

In order to meet US government requirements and continue to sell its top-of-the-line video card in China, Nvidia has cut back a bit basic RTX 4090 and added the index D to it. This is what came out of it:

Which is better: RTX 4090 or RTX 4090D

From the comparative table above, it can be seen that the key RTX 4090D downgrade compared to regular RTX 4090 touched on three types of kernels: CUDA, Tensor and RT. In the light version, they became about 10% less than in the classic version. Accordingly, energy consumption also fell by almost 6%. Despite this, the base frequency of the video core in the D-modification even increased slightly, which gave a certain boost to synthetic tests.

MSI Suprim X will allow you to adjust the frequency through Afterburner

Blocked overclocking potential was also initially reported. However, after the appearance of a new video card on sale, it turned out that it can still be overclocked, even if not as much as the classic version. The first testers were able to increase the clock frequency of the video core RTX 4090Dwhich added the graphics card about 2% productivity. However, this turned out to be the maximum for her – strictly limited energy consumption was indicated.

The most convenient way Nvidia GeForce RTX 4090D performance tuning will be available to MSI Suprim X video card buyers via MSI Afterburner. Out of the box, it will offer the ability to switch between quiet and productive modes, which differ in clock frequency and final performance.

The gap between RTX 4090 and RTX 4090D cannot be called critical

Real power reserve RTX 4090D as expected, it turned out to be slightly lower than that of the RTX 4090. Comparison of both video cards in games in 4K resolution at the highest graphics settings showed a gap of 6-9% fps in favor of a full-fledged video card. CPU-based assembly was used for testing Intel Core i9-13900KSZhiqi Magic Front Halberd DDR5-7200 16GB * 2 CL34-45-45-115 RAM and Asus ROG MAXIMUS Z790 DARK HERO motherboard:

F1 2022

CS2

204.9

The existing gap cannot be called anything but catastrophic, but even a little significant. First of all, because the potential RTX 4090 can be considered excessive, and in practice you probably won’t notice the difference even with it on DLSSeven without him.

How much does the RTX 4090D cost and is it worth buying?

Another thing is that RTX 4090D price at the start of sales is equal to RTX 4090 prices and makes 12,999 yuan (approximately 162,000 rubles at the exchange rate). Apparently, it is not scary, considering the vicissitudes that Nvidia had to overcome in order to bring its top video card to the Chinese market. It’s just that it’s psychologically uncomfortable for many to pay the same amount for, even if only a little, but a shortened product.

The RTX 4090D seriously outperforms the RTX 3090 Ti

Nvidia itself does not seem to shy away from the RTX 4090D at all and shows its advantages over the previous generation video card without any hesitation. The graphic above clearly shows that the new card is seriously superior RTX 3090 Ti in all games selected for the test. Therefore, it is probably not worth getting upset about the reduction in productivity, which should have a noticeable effect only on the training of artificial intelligence.

However, so far about sales of GeForce RTX 4090D not reported outside of China. After all, this video card was originally aimed at him, and Russia, which, although under sanctions, is not such a big player in the field of AI infrastructure development on the international stage. Therefore, it is most likely not worth waiting for direct sales of a new video card on the Russian market. But if she does get here, buy RTX 4090D it will be possible in XCOM-SHOP.RU. As always, at a very attractive price.
