The AMD Radeon RX 6700 and RX 6700 XT are expected during March

AMD's Radeon RX 6800 and 6900 series graphics cards are just the beginning of the company's RDNA 2 line. Radeon RX 6000 models from the lower segment are also arriving, offering gamers a lower price with a better value compared to the premium Big Navi line.

The Radeon RX 6700 and RX 6700 XT graphics cards will replace the models from the current RX 5700 series. Gamers will thus be offered the benefits of the AMD RDNA 2 architecture, which include support for Microsoft DirectX 12 Ultimate feature set, higher clock speeds, and support for hardware-accelerated ray tracing via Vulcan and DirectX 12.

The Radeon RX 6700 series is expected to be released at the end of the first quarter, and if earlier rumors are true, the standard and XT GPU models will have Infinity Cache memory, 12GB of GDDR6 RAM, and a 192-bit memory bus.

The series will be based on the AMD Navi 22 XT architecture, which reportedly has 40 CUs (compute units), suggesting that the RX 6700 XT model will have those 40 CUs and will be an RDNA 2 replacement for the RX 5700 XT model.
