XFX SPEEDSTER MERC310 Radeon RX 7900 XT graphics card RX-79TMERCB9

XFX SPEEDSTER MERC310 Radeon RX 7900 XT

The XFX SPEEDSTER MERC310 Radeon RX 7900 XT is a refurbished graphics card built for gamers and creators who need high frame rates at 4K resolution. It uses the AMD RDNA 3 architecture with 5376 stream processors and a 320-bit memory bus. The card connects through a PCI Express 4.0 x16 slot and supports up to four displays via one HDMI 2.1 and three DisplayPort 1.4 outputs.

Sustained load behaviour with triple-fan cooler

A triple-fan thermal solution manages the 290 watt thermal design power during extended gaming or rendering sessions. The boost clock reaches 2560 MHz while the game clock sits at 2200 MHz, allowing the GPU to maintain higher frequencies for longer periods. An 800 watt power supply is recommended to keep the system stable under continuous heavy workloads.

20GB GDDR6 decides 4K texture headroom

The 20GB GDDR6 frame buffer connected over a 320-bit interface determines whether this card can hold the largest texture packs and geometry datasets at 7680 x 4320 resolution. If your workflow or favourite titles regularly exceed 16GB of video memory, this capacity prevents swapping to system RAM. If they stay below that threshold, a smaller buffer would deliver similar frame rates.
