Many cards are created from used adapters In China, a full-fledged hunt has begun for video cards that can at least somehow be turned into accelerators for AI. We have already talked about redesigning the RTX 4090 and RTX 3090 , but the Chinese went further and began to add memory to even less powerful adapters.  [caption id="attachment_84870" align="aligncenter" width="780"] RTX 3080 20GB and Radeon RX 580[/caption] The companies involved began creating versions of 3D maps that had never been released. For example, GeForce RTX 3080 with 20 GB of memory and even Radeon RX 580 with 16 GB. The second one by modern standards and especially by the standards of accelerators for AI is very weak, but in some scenarios it is not performance that is more important, but the amount of memory. RTX 3080 20GB and Radeon RX 580 16GB have already been created  [caption id="attachment_84871" align="aligncenter" width="780"] RTX 3080 20GB and Radeon RX 580[/caption] Moreover, at least in the case of the RX 580, of course, we are talking about modifying far from new adapters. It is reported that many of the cards that are now getting new life were previously involved in mining. Moreover, interestingly, companies engaged in such production provide a two-year warranty on such adapters. Apparently, the demand is such that overall sales more than cover the risks of failure of devices that are no longer new.

And not only to China It turned out that not only the H800 and A800 accelerators, which China needs for development in the field of artificial intelligence, were subject to new US sanctions. Regular RTX 4090 is now also banned for the Chinese. [caption id="attachment_71132" align="aligncenter" width="780"] GeForce RTX 4090[/caption] The US even banned deliveries to China of the GeForce RTX 4090 More precisely, the list includes the following Nvidia models: A100, A800, H100, H800, L40, L40S, and RTX 4090. Considering that the new rules are based on performance and TFLOPS per square meter. mm, probably the RTX 4090 is simply too powerful and therefore falls into the same category as specialized solutions. It is also worth noting that it is not only China that will no longer be able to obtain such adapters. The ban also applies to Saudi Arabia, the United Arab Emirates and Vietnam. If they stop supplying gaming RTX 4090 to China, these cards will probably skyrocket in price in this country.

Card prices still vary greatly The authors of the Hardware Unboxed channel decided to test the Radeon RX 7900 XTX and GeForce RTX 4080 video cards again, pitting them against each other in a head-to-head battle. But unlike most other tests, in the new one they decided to fully address both regular raster performance, and performance with ray tracing, and performance with ray tracing with active upscale technologies. [caption id="attachment_64065" align="aligncenter" width="780"] Radeon RX 7900 XTX vs GeForce RTX 4080[/caption] Since the tested cards are top-end solutions, it makes sense to talk only about 4K resolution, although the authors tested cards in all major resolutions. So, the raster performance of the RX 7900 XTX is higher than the RTX 4080, which is not news. In the case of the specific selection of games available here, we are talking about a 7% advantage, but it is worth noting that the result in Fortnite stands out strongly from the rest and shifts the overall result in favor of the Nvidia card. If this game is removed, Radeon's advantage will be significantly higher. Radeon RX 7900 XTX vs GeForce RTX 4080 with and without tracing, with and without DLSS/FSR. When ray tracing effects are activated, the RTX 4080 takes the lead, 7% ahead of its competitor. At the same time, for example, in Cyberpunk 2077 the difference reaches an impressive 30%, and in Ratchet & Clank, it even exceeds 40%. https://youtu.be/YbKhxjw8EUE?t=1303 If you activate both tracing and DLSS/FSR in games, the Radeon RX 7900 XTX will lag behind its competitor by 11%. Interestingly, in the same Fortnite, where the AMD card is much inferior to the Nvidia card in raster performance, it is also ahead of the RTX 4080 in the last tested mode. We can summarize that the maps are generally close. The AMD flagship is faster without ray tracing, and the Nvidia card is faster with ray tracing regardless of upscale technologies. At the same time, the RTX 4080 has lower power consumption and more widespread DLSS technology. However, the Radeon RX 7900 XTX has a completely different trump card. This card is much cheaper. If the RTX 4080 in the US costs about $1,100, the RX 7900 XTX can be purchased for $900, and sometimes there are even cheaper offers.

But out of the box, the Nvidia card is much more energy-efficient The Radeon RX 7800 XT video card, at its price of $500, performed well against the RTX 4070, which costs $600. However, the latter is much more energy efficient. Tests from the Techtesters channel have shown that, if desired, an AMD card can also be made much more efficient.  [caption id="attachment_58076" align="aligncenter" width="780"] Radeon RX 7800 XT[/caption] It turned out that the consumption of the RX 7800 XT can be lowered to the level of the RTX 4070, that is, about 200 W. Moreover, even in this mode, AMD’s new product is not inferior to its competitor. True, an Nvidia card can also be undervolted, but this was not done in this test.  As for the loss of performance of the AMD adapter, Gigabyte's overclocked RX 7800 XT consumes 40% more power than the version with a reduced power limit, while the former's performance is only 9% higher.  https://youtu.be/83Gz_A-luXI
