AMD Radeon RX 7900 XT

320-bit · 5,376 cores

The Radeon RX 7900 XT launched alongside the RX 7900 XTX on December 13, 2022 as one of the first consumer graphics cards built from chiplets: a 5 nm graphics compute die surrounded by 6 nm memory cache dies that carry its 80 MB of Infinity Cache. It is a cut-down Navi 31 with 84 of the 96 compute units and five of the six memory cache dies enabled, and AMD aimed it at high-refresh 1440p and 4K gaming at a launch price of $899.

Notes
RDNA 3 WMMA matrix instructions support FP16, BF16, INT8 and INT4. No FP8 and no TF32 (TF32 is an NVIDIA format). FP64 is supported at a reduced rate. The 103 TOPS figure is AMD's dense INT8 matrix rate; INT4 is 206 TOPS.
