XFX MERC 310 Radeon RX 7900 XT Review: Bigger, Badder RDNA 3
XFX MERC 310 Radeon RX 7900 XT: A Massive Navi 31 For Gamers
|XFX MERC 310 Radeon RX 7900 XT: $949 - $979 (expected)
The new XFX MERC 310 Radeon RX 7900 XT offers higher clocks and beefier cooler than AMD's cards, but that results in a larger form factor and higher price.
Radeon RX 7900 series cards can do, but in this piece we’ll be highlighting a third-party partner board from XFX, the MERC 310 Radeon RX 7900 XT. As we saw with NVIDIA’s initial GeForce RTX 40 series launches, AMD board partners seem to be taking the company’s reference designs and then pushing them to the extreme. The MERC 310, for example, offers modestly higher boost clocks, but features a much larger PCB and cooling assembly that extends the card's length to 13.5”. AMD’s own Radeon RX 7900 XTX is only 11.2” long, for context.
The MERC 310 Radeon RX 7900 XT diverges from AMD’s design in a number of additional ways as well, which we’ll get to shortly. First up, we have some specs to go over and then it’s time for a tour and some benchmarks...

At its core the MERC 310 Radeon RX 7900 XT is just like AMD’s own Radeon RX 7900 XT. Both cards share the same base feature set and have somewhat similar power and performance targets, give or take a few percentage points. In addition to the different PCB and cooler designs, the XFX MERC 310 ups the expected frequencies from AMD’s reference 2,000MHz game clock and 2,400MHz boost clock, to "up to” 2,220MHz and 2,560MHz and the BIOS is tweaked for slightly higher power (by 18-33 watts). Memory clock and capacity remains similar to AMD’s cards with 20GB on board, at an effective data rate of 20Gbps.
To support those higher clocks and power, the XFX MERC 310 Radeon RX 7900 XT employs a full digital 13+1 PWM, to ensure the GPU and memory have stable power delivery. There are also thermal pads incorporated throughout the card for components on both the front and back of the PCB – there are 20 thermal pads used in total, to aid in cooling the memory and VREGs. Those thermal pads make contact with the PCB components, back plate, and large heatsink fin stack.
Although the XFX MERC 310 Radeon RX 7900 XT is built like a tank and as solid as they come, all of the weight that comes by way of a massive cooler which can place a lot of stress on an expansion slot. To that end, XFX includes what they’re calling a “Z Support Bar System” that wraps around the entire card and screws into a chassis for additional support.
