AMD Radeon RX 7900 XTX announced with 24 GB VRAM, 355 W TGP and a relatively affordable price tag

Although they came quite late, a few rumours suggested that the AMD Radeon RX 7900 XTX would be the flagship RDNA 3 card, and not the Radeon RX 7900 XT. AMD has confirmed said statements and officially announced both graphics cards. While it doesn't quite live up to the hype generated by earlier leaks, it comes as a breath of fresh air in an era of prohibitively expensive, power-hungry graphics cards.

The AMD Radeon RX 7900 XTX will feature the world's first chiplet-based GPU, which also happened to be pictured earlier today, complete with one TSMC N5 GCD (graphics complex die) and six TSMC N6 MCDs (memory complex die). It features 96 CUs (compute units), 24 GB of 20 Gbps GDDR6 RAM on a 384-bit bus, a 2.3 GHz game clock, DP 2.1 support and a TGP of 355 Watts. It relies on two 8-pin PCI-e power cables, eliminating the need for potentially hazardous power adaptors.

AMD claims that the Radeon RX 7900 XTX delivers over 54% performance/watt compared to RDNA 2. It is up to 1.7x times faster than the Radeon RX 6950 XT at 4K in select titles. Raytracing performance isn't nearly as impressive, but the graphics card manages to push over 60 FPS in titles such as Cyberpunk 2077 and Dying Light 2, at least with FSR enabled. AV1 encode/decode functionality is also available.

As predicted by earlier leaks, the wait time between the Radeon RX 7900 XTX announcement and the sale date will be quite long. One can purchase the graphics card starting December 13 2022 for just US$999. It is far too early to predict how it'll perform, but it is unlikely to dethrone the GeForce RTX 4090 anytime soon, at least not with these lukewarm clocks.
