These cards aren’t merely specced upgrades. Su claims that RDNA 3 is the world’s first chipset-based GPU, with a modular architecture that can be readily modified in the future. These chiplets currently feature a 5nm GPU compute die and a 6nm memory cache die. It has a computational capability of up to 61 teraflops (up from a maximum of 23 TFLOPs in RDNA 2), can handle up to 24GB of GDDR6 RAM, and has 58 billion transistors.
Naturally, the Radeon RX 7900 XTX receives the entire 24GB of RAM, while the 7900 XT gets 20GB. Both cards resemble AMD’s previous-generation technology, but with larger fans and a sleeker heatsink design. AMD SVP Sam Naffziger also joked that these cards won’t need any additional power cords and should fit into your old system.
