AMD is gearing up for its mid-range Radeon RX 6750 XT refresh GPU launch, which is reportedly taking place on May 10 -- where the new flagship Radeon RX 6950 XT will also reportedly be introduced.Ahead of the launch, PowerColor's new Radeon RX 6750 XT Red Devil has been teased with a new filing with the RAA on March 29. The listing doesn't tell us much, as it is listed as the "AXRX 6750XT 12GBD6-3DHEOC". You can see the "6750XT" there and "12GB" as well, and "OC" of course -- so an overclocked Radeon RX 6750 XT with 12GB of GDDR6 (non-X) from PowerColor.Inside, the Radeon RX 6750 XT will be using the Navi 22 GPU which has 2560 Stream Processors and 12GB of GDDR6 memory on a 128-bit memory bus. AMD is refreshing all of its new GPUs with 18Gbps GDDR6 memory (up from 16Gbps on the other cards) which includes the lower-end Radeon RX 6650 XT, the Radeon RX 6750 XT, and the new flagship Radeon RX 6950 XT graphics cards.AMD is expected to launch its new Radeon RX 6000 series refresh GPUs on May 10.
