Graphics card XFX Radeon RX 7900 XTX 24 GB GDDR6, PCIe 4.0, 384-bit, 355 W, 3x fans

The XFX MERC 310 AMD Radeon RX 7900 XTX 24 GB GDDR6 is a high-performance graphics card built on AMD RDNA™ 3 architecture with chiplet technology. Designed for 4K and beyond, it pairs 24 GB of GDDR6 memory and a 384-bit memory bus with a 1855 MHz processor frequency and PCI Express 4.0 interface. The MERC 310 cooler features a vapor chamber, triple-fan active cooling and an updated ridged backplate to improve heat dissipation and maintain stable performance under load.

Advantages

The card offers next-generation performance with AMD RDNA™ 3 compute units, 2nd generation raytracing accelerators and AI accelerators, plus 96 MB Infinity Cache for improved effective memory bandwidth. XFX cooling enhancements—vapor chamber, straight-through airflow Ghost Thermal shroud, double ball bearing fans and an enlarged ridged backplate—improve thermal transfer and longevity. A 12+3+2 phase power design and dual BIOS provide stability and flexible overclocking headroom. Additional features include DisplayPort 2.1/USB-C support, 12-bit HDR color processing and a 3-year limited warranty from XFX.
