AMD Radeon RX 7900 XT

The AMD Radeon RX 7900 XT is a high end desktop graphics card based on the RDNA 3 architecture. It uses the Navi 31 Chip with consists out of a Graphics Compute Die (GCD) manufactured in 5nm and five (out of six) Memory Cache Dies (MCD chiplets) in 6nm. The 7900 XT offers 5.376 cores clocked at up to 2.4 GHz (max, 2 GHz game average), 80 MB Infinity Cache (L3 cache) and 20 GB GDDR6 graphics memory with a 320 Bit memory bus and 20 Gbps effective speed.

The average gaming performance is slightly below the GeForce RTX 4080 in games (without raytracing). Therefore, the RX 7900 XT is best suited for QHD (for higher frame rates) up to 4K resolution and maximum detail settings of 2022 games. Raytracing performance is still a bit lower than with Nvidia cards, but a big step up from the previous generation.

The integrated video en- and decoders support AV1, H.264, and HEVC videos wit up to 8K resolution. The display ports are a big advantage of the new chip supporting DisplayPort 2.1 with UHBR13.5 for up to 54 Gbps bandwidth (up to 8K 165 Hz with DSC possible).

The power consumption is rated 315 Watt and in our tests similar to the RTX 4080.
