Features a clean, industrial silver and black design with a highly efficient vapor chamber cooling system. A 24GB VRAM behemoth.

A 24GB GDDR6 configuration with a 384-bit memory bus provides up to 960 GB/s of memory bandwidth.
The three-fan thermal solution uses a vapor chamber cooling design in a silver-and-black card measuring 344 x 128 x 57 mm.
The Radeon RX 7900 XTX features 6,144 stream processors, ray tracing support, and DisplayPort 2.1 and HDMI 2.1 interfaces.
The XFX Speedster MERC310 AMD Radeon RX 7900 XTX Black is an AMD RDNA 3 graphics card with 24GB of GDDR6 memory, a triple-fan vapor chamber cooling design, and PCIe 4.0 x16 connectivity.
The reviewer highlights the card's exceptional thermal management and silent operation, calling it a perfect refinement of the reference RX 7900 XTX design. It is praised for delivering performance that exceeds the RTX 4080 and provides a value-oriented high-end option, though ray tracing capabilities lag behind Nvidia's 40-series cards. It received an Editors' Choice Award.
The reviewer concludes that the card is a great custom design featuring superior thermals, a beefed-up board, and beautiful aesthetics, making it a strong choice for those opting for AMD this generation. It is noted to be a large, chunky card, and users are advised to be mindful of pricing.
The card is described as a beast that provides impressive next-gen performance for high-end gaming rigs. The review emphasizes its ability to build virtual worlds in spectacular fashion if paired with appropriate components.
