AMD unveiled the Radeon RX 7900 XTX and Radeon RX 7900 XT graphics cards, revealing specs that could prove to be healthy competition for Nvidia’s 40-series GPUs. These are the first two graphics cards from AMD’s Radeon RX 7000 series, based on RDNA 3 microarchitecture and TSMC’s 5nm chiplet. AMD CEO Lisu Su teased Radeon RX 7000 reveals earlier this year, but the now-confirmed RX 7900 XTX and RX 7900 XT specs and release details likely surprised, regardless.
An important aspect of the new RX 7000 GPUs revolves around the core issue of ray tracing. AMD has been heavily criticized for the lack of ray tracing support for its RX 6000 series cards, but has taken this feedback on board. As previously known, the RX 7000 GPUs include a new ray tracing accelerator compute unit. This accelerator should provide a 50% improvement in ray tracing over standard GPU ray tracing performance. As for what that means, AMD’s recently confirmed specifications for RX 7000 traffic cards help provide clarity.
The AMD Radeon RX 7900 XTX has 96 compute units in its Graphics Computer Die. This should deliver what AMD says is a gaming clock speed of 2.3GHz. The GPU is paired with a powerful 24GB of memory, which runs at 20 Gbps over a 384-bit memory bus. The AMD Radeon RX 7900 XT is a step down, with 84 compute units, 20GB of memory over a 320-bit bus, and a 2GHz game clock speed. Both cards support DisplayPort 2.1 connections.
To frame the performance of its cards, AMD provided some of its own in-game frame rate metrics. The RX 7900 XTX is said to deliver up to 295 fps Apex Legends and 355 fps in Overwatch 2 in 4K resolution. Cyberpunk 2077, running at 4K with ultra-detect settings, delivers up to 62 fps. AMD compares it to the RX 6950 XT, which manages 42 fps of ray tracing Cyberpunk 2077. A similar ray tracing comparison is made with Dying Light 2with the RX 7900 XTX managing 32 fps next to the RX 6950 XT’s 39 fps.
While AMD didn’t provide a direct comparison between its RX 7000 GPUs and Nvidia’s 4000 series cards, it did take some shots at its competitor. He joked about the RX 7000 cards having dual 8-inch power sockets, a reference to Nvidia’s problems with the RTX 4090’s 12-pin sockets melting. DisplayPort 2.1 support was also heavily mentioned, another feature missing from Nvidia cards.
But what makes AMD’s RX 7000 cards stand out are their prices. The RX 7900 XTX costs $999 and the RX 7900 XT is $100 less at $899. While these aren’t entry-level prices, they’re more than $500 more affordable than Nvidia’s most expensive RTX 4000 cards. Both AMD Radeon RX 7900 XTX and RX 7900 XT will be released on December 13, 2022. Expect further AMD card announcements in the coming months.
