Radeon RX 7900 XT Up to Three Times Faster Than RX 6900 XT
After almost half a year after the release of Radeon RX 6900 XT has passed, first information about its successor, based on RDNA 3 architecture, appeared on the web. RX 7900 XT is to be up to three times more efficient than the current AMD flagship.
The latest leak concerns the most powerful chip based on RDNA 3 architecture, namely Navi 31 (successor to Navi 21, on which Radeon RX 6900 XT, RX 6800 XT and RX 6800 are based). According to numerous sources, the most powerful representative of next year's GPU line from AMD, probably hiding under the name Radeon RX 7900 XT, is to use a chiplet design, and also be constructed in 5 nm technological process. This will make it possible to use two chiplets, where one of them will have 80 CU blocks.
As we can easily count, this will translate into 160 Compute Units, which will give a total of 10240 stream processors, and the use of TSMC's 5nm technology process will reduce power consumption. The core size itself should also decrease compared to Big Navi, which uses 7 nm lithography. The new graphics chips from AMD will also utilize a newly patented active interconnect bridge. Previous rumors suggest that it runs at full core bandwidth. All this is expected to translate into a high performance boost for the Radeon RX 7000 series GPUs, with the RX 7900 XT expected to have up to three times the processing power of the RDNA 2-based flagship, the Radeon RX 6900 XT. Unfortunately, but in the case of ray tracing according to unofficial reports, we can only expect catching up with the performance of top Nvidia GeForce RTX 3000 cards.
However, the above information should be approached with caution. The new AMD RDNA 3 architecture will probably be presented only next year, and the first Radeon RX 7000 GPUs using the new Navi cores will not appear before the end of 2022. Until then, a lot can still change. However, if the rumors turn out to be true, we will be dealing with a really big increase in performance. For now, we can only wait for further developments and hope that AMD's new graphics cards will achieve success, and the rivalry in the GPU market with Nvidia will only intensify to the benefit of gamers.
