AMD Readies Radeon RX 6500 XT and RX 6400 Graphics Cards
The Navi 24 silicon features a 64-bit wide GDDR6 memory interface, which is paired with 4 GB of discrete memory on both SKUs. This memory operates at 14 Gbps data-rate, which works out to 112 GB/s memory bandwidth. Interestingly, the Infinity Cache makes a comeback, in the form of a tiny 16 MB on-die cache that cushions the memory sub-system. The RX 6500 XT could have just enough muscle for e-sports gaming at 1080p, while the RX 6400 seems more like a card you’d buy just because your processor lacks integrated graphics (eg: if you’re using a Ryzen 5000X processor and just need a graphics solution that meets the latest display I/O and media-acceleration standards). At this point we don’t know if the Navi 24 is DirectX 12 Ultimate compliant, i.e., featuring Ray Accelerators on its compute units. Both cards are expected to launch in Q1, 2022.
