Yesterday I had the chance to check out both of AMD's reference cards for the Radeon RX 7900 XTX and XT launch. Well, today cards are available for sale and alongside of that, I have the opportunity to check out an aftermarket card from XFX, specifically the XFX MERC 310 7900 XT. This gives us a great chance to check out how XFX’s card compares with the stock-clocked reference design both in performance but also in cooling and noise. Being an aftermarket card, the MERC 310 7900 XT is larger than AMDs design, and XFX has used that as a chance to up the clock speeds as well with the game clock increased from 2000 MHz up to 2220 MHz and the boost clock which on the reference card can go up to 2400 MHz can go up to 2560 MHz on XFX’s card which is a big overclock. So let’s dive in and see what XFX has to offer!

As I mentioned in the opening, this is an overclocked card and XFX has given it a bigger than average overclock over the stock reference card clock speeds. The game clock is set to up to 2220 MHz compared to 2000 of the reference card and the boost clock is up to 2560 MHz compared to 2400 MHz on the reference card. I did run GPUz before testing but sadly as of writing this it hasn’t been updated with support for the new cards so the clock speeds were all over the place and with that, I couldn’t confirm the clock speeds match the specs. I tested with the press prerelease driver and GPUz also isn’t picking up the BIOS revision number just yet so it isn’t documenting that like we normally do.
