AMD Radeon RX 7900 XTX
The AMD Radeon RX 7900 XTX 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 all six Memory Cache Dies (MCD chiplets) in 6nm. The 7900 XT offers 6.144 cores clocked at up to 2.5 GHz (max., 2.3 GHz average game clock), 98 MB Infinity Cache (L3 cache) and 24 GB GDDR6 graphics memory with a 384 Bit memory bus and 20 Gbps effective speed.
The average gaming performance is between a Nvidia GeForce RTX 4080 and RTX 4090 and therefore well suited for 4K gaming of 2022 games (see benchmarks below). 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 355 Watt and in our tests was similar to a RTX 4090 (but on different platforms).
