VideoCardz writes we can expect the Radeon RX 6500 XT and Radeon RX 6400 in the first quarter of 2022.
The Radeon RX 6500 XT uses the Navi 24 XT and allegedly has 1024 streaming processors. The Radeon RX 6400 on the other hand will get the Navi 24 XL, with an alleged core count of 768. Both models will feature Ray Accelerators. Memory configurations are pretty poor though, both cards will get just 4GB GDDR6 memory clocked at 14Gbps on a 64-bit memory bus, resulting in 112GB/s of memory bandwidth.
AMD Radeon RX 6400 is also based on Navi 24 GPU however it has fewer Compute Units enabled (12 out of 16). Thus, the graphics card is to offer 768 Stream Processors. Similarly to RX 6500 XT, it will ship with 4GB GDDR6 memory across the 64-bit bus. The most important difference is that RX 6400 will not require a separate power connector as the power delivered through the PCIe slot will be sufficient. The RX 6400, therefore, has a TBP lower than 75W.
