AMD Radeon RX 7900 XTX: Nvidia GeForce RTX 4090 Ti competitor with 24 GB GDDR6 VRAM reportedly in the works ^↺

A previous report said that the AMD Radeon RX 7900 XT wouldn't be the flagship RDNA 3 graphics card and launch with 20 GB of video memory. That spot was supposedly reserved for the eventual Radeon RX 7950 XT. Now, a new report says it will be called the Radeon RX 7900 XTX. Benchlife (via Videocardz) has learned from its sources that the high-end graphics card will feature 24 GB GDDR6 VRAM on a 384-bit bus.

Kepler_L2 weighs in, stating that only the Radeon RX 7900 XT and above will use AMD's flagship Navi 31 GPU. The Radeon RX 7800 XT will be relegated to using a Navi 32 GPU; quite unlike its predecessor (Radeon RX 6800 XT), which used a Navi 21 XT GPU. Kepler adds that AMD has plans to launch a 3D V-cache variant of the Radeon RX 7900 at some point with the same number of WGPs (work group processor) as the base model but twice the amount of infinity cache. It could be launched as the Radeon RX 7950 XT or the Radeon RX 7900 XT X3D (truncated to Radeon RX 7900 XTX).

If rumours about the Radeon RX 7900 XTX are true, Team Red finally has a chance at taking the fight to Nvidia this generation. It could even take on the eventual GeForce RTX 4090 Ti due to be launched sometime next year. It'll be interesting to see how much power the Radeon RX 7900 XTX draws, but it will almost certainly be lower than its direct Ada Lovelace competitor. Additionally, AMD could also win the price war this generation due to the relatively cheap manufacturing costs of RDNA 3 graphics cards.
