XFX Radeon RX 7900 XT SPEEDSTER MERC310 20GB GDDR6 Black

The XFX MERC310 RX 7900 XT is a 4K gaming beast with 20GB of VRAM and top-tier raster performance. It runs cool but it's huge, power-hungry, and some units have coil whine. At $770, it's one of the best values in high-end gaming right now.

The 7900 XT chews through 1440p and 4K gaming without breaking a sweat. With 5376 stream processors and a 2560MHz boost clock, it lands in the 89th percentile for compute and ray tracing in our database. The 20GB of VRAM is a standout too, giving you plenty of headroom for high-res textures. PassMark G3D hits 29059, which puts it among the best cards we've tracked. The weak spot is AI and LLM workloads, scoring 69.1 out of 100. If you're training models or running local AI, this isn't the card for you. For pure gaming, it's a monster.

Against the RTX 5080 cards from ASUS and Gigabyte, the 7900 XT holds its own in rasterization but falls behind in ray tracing and AI workloads. The MSI Ventus RTX 5070 Ti is a closer match on price, but the XFX card's 20GB of VRAM gives it an edge for high-res gaming. The Sapphire NITRO+ 7900 XTX is the step-up option if you want even more performance, but you'll pay for it. For pure gaming value, this XFX card is hard to beat.

At $770 USD, this card is a strong deal for high-end gaming. You're getting near-flagship raster performance and 20GB of VRAM for hundreds less than comparable Nvidia cards. The affordability score sits at the 32nd percentile, which sounds rough, but that's because we're comparing against budget cards too. For what it delivers, owners consistently call it a great value. If you're avoiding Nvidia's pricing, this is one of the best ways to get 4K gaming without selling a kidney.

The XFX Speedster MERC310 RX 7900 XT is a big, fast, no-nonsense 4K card. It packs 20GB of GDDR6 and AMD's RDNA 3 architecture, and our database puts it in the 90th percentile for features and 89th for compute. That's top-tier territory without the top-tier Nvidia tax.

But this thing is huge. At 344mm long and nearly three slots thick, it's going to bully its way into your case. You'll want an anti-sag bracket and a serious power supply. If you've got the space and the watts, though, this card delivers serious frame rates for the money.

Skip this if you're into AI workloads, local LLMs, or heavy ray tracing. The AI score of 69.1 is mediocre, and Nvidia's RTX cards pull ahead in ray-traced titles. Also skip it if you have a compact case or a PSU under 800W, this card demands space and power.

If you want a 4K gaming card that doesn't cost Nvidia money, this is it. The XFX MERC310 7900 XT delivers excellent frame rates, runs cool, and has enough VRAM to stay relevant for years. Just make sure your case can fit a 344mm card and your PSU can handle 315W. Gamers who want top-tier ray tracing or AI performance should look elsewhere, but for pure rasterized gaming, this is a fantastic buy.
