XFX Speedster Merc 310 20GB

The XFX Speedster Merc 310 is a Radeon RX 7900 XT graphics card equipped with 20GB of GDDR6 memory on a 320-Bit interface. It targets gamers and creators who need high frame rates at 4K resolution and beyond. The GPU runs on AMD RDNA 3 architecture with 5376 stream processors. Core, game and boost clocks are rated at 1500 MHz, 2200 MHz and 2560 MHz respectively.

PCIe 4.0 x16 and display outputs

The card plugs into a PCI Express 4.0 x16 slot and provides one HDMI 2.1 port alongside three DisplayPort 1.4 connectors. This layout supports up to four simultaneous monitors at a maximum resolution of 7680 x 4320. DirectX 12 Ultimate and OpenGL 4.6 compatibility ensures current API coverage for games and creative workloads.

Triple-fan cooler and build

A triple-fan cooling assembly covers the full-length board, moving heat away from the 7900 XT GPU and 20GB memory array. The shroud and backplate form a rigid structure that resists flex during installation and transport. Standard bracket screws secure the I/O plate to the chassis, keeping the HDMI and DisplayPort connectors aligned for reliable cable seating day to day.

Questions about this item

Will the triple-fan cooler on the MERC 310 need dust cleaning or thermal-paste renewal after long use?

The card uses a triple-fan cooler; dust can be removed with compressed air and thermal paste typically lasts several years before any renewal is considered.

What thermal limit appears first when the Radeon RX 7900 XT runs at its 2560 MHz boost clock for hours?

The GPU will hit its power and temperature targets before any memory bottleneck, so the boost clock sustains until the cooler reaches its thermal ceiling.

How loud and hot does the triple-fan design get during all-day 4K gaming at 7680 x 4320?

Three fans keep the Radeon RX 7900 XT at moderate noise levels while exhausting heat through the rear bracket, even at the 2560 MHz boost clock.
