XFX Radeon RX 7900 XT Speedster MERC310 20GB GDDR6

The XFX MERC310 RX 7900 XT posts a PassMark G3D score of 29,059, putting it in the top tier for gaming performance. With 20GB of VRAM and excellent 1440p and 4K results, it's a strong buy at the USD 650 low end of its price range. Just make sure your case can handle the 344mm length and you're okay with some fan noise under load.

The 29,059 PassMark G3D score is the star here. That's a standout result, putting this card among the best on the market for rasterization. The 2,535MHz boost clock and 20GB of GDDR6 give it serious legs in demanding titles. Owners report high frame rates in Cyberpunk 2077 and Baldur's Gate 3 at both 1440p and 4K, which matches what we'd expect from the 81st percentile raster ranking. Ray tracing performance is strong too, landing in the 79th percentile, though it's not quite the absolute best right now.

The 96 RT cores and 192 Tensor cores handle ray tracing and AI workloads respectably, but the compute score tells a different story. At 2.611 FP32 TFLOPS, this card sits in the 28th percentile for compute, which is mediocre for workstation tasks. Our scoring reflects that: 56.8/100 for workstation use is the weakest area. If you're gaming, you'll love it. If you're rendering or doing heavy compute, there are better options at this price point. The 350W TDP also means efficiency is underwhelming at the 39th percentile, so your power bill will notice this card.

Against the current crop of competitors, the MERC310 holds its own in gaming but falls behind in other areas. The ASUS PRIME RTX 5080 and Gigabyte AORUS RTX 5080 both beat it on ray tracing and compute, though they typically cost more. The MSI Ventus RTX 5070 Ti is a closer match on price and offers better efficiency, but gives up VRAM with 16GB versus this card's 20GB. The Sapphire NITRO+ is the most direct AMD alternative, and it trades blows on raster performance while offering a slightly different cooling approach. The ZOTAC APOCALYPSE RTX 5080 is the wildcard, with stronger compute but a higher typical price. If pure gaming frame rates are your priority and you can find this XFX at the low end of its price range, it's hard to beat. If you need workstation performance or care about power draw, the RTX 5080 options pull ahead.

Pricing on this card is all over the place depending on where you shop. In the US, we're seeing listings from USD 650 to USD 1,275 across three vendors. That's a USD 625 spread, which is wild. The USD 650 listing is the one to jump on if you can find it in stock, because at that price this card is an absolute steal for 4K gaming. In Europe, the spread is EUR 523, ranging from EUR 1,009 to EUR 1,532 across four listings. The EUR 1,009 option is the best deal there. At the higher end of those ranges, you're paying too much for what you get, especially with the compute and efficiency weaknesses. The 28th percentile affordability ranking reflects that the typical asking price is on the steep side, but the value proposition changes dramatically if you catch a good listing.

The XFX Speedster MERC310 RX 7900 XT lands a PassMark G3D score of 29,059, which puts it in the top tier of our GPU database for raw raster performance. That's the headline number, and it translates to a card that chews through 1440p and 4K gaming without breaking a sweat. With 20GB of GDDR6 on a 256-bit bus, you're also getting enough VRAM headroom to keep texture-heavy titles happy for a while. Our scoring backs this up: 77.5/100 for 4K gaming and 76.7/100 for 1440p, both well above average.

But this card is not subtle about its physical presence. At 344mm long and 2.75 slots thick, it demands a case with real estate to spare. Owners consistently mention the length as the first thing you notice when unboxing. The triple fan MERC cooling solution keeps temperatures in the 55-75°C range under load, which is genuinely impressive for a 350W TDP card. The trade-off is noise: the stock fan curve gets loud when you push it, and a handful of users report coil whine that fades after a few seconds.

If you're doing workstation tasks like rendering, video editing, or heavy compute, this card is not your best option. The 56.8/100 workstation score and 28th percentile compute ranking tell the story: the 2.611 FP32 TFLOPS just doesn't compete with similarly priced options. The 350W TDP and 39th percentile efficiency also mean higher power bills over time. And if your case is on the smaller side, the 344mm length is a dealbreaker. You'd be better served by an RTX 5080 variant or a more compact card that fits your build without a case upgrade.

The XFX Speedster MERC310 RX 7900 XT is a gaming beast that makes a strong case for itself, especially if you catch it at the USD 650 end of the pricing spectrum. The 29,059 PassMark score and 20GB of VRAM deliver excellent 1440p and 4K performance, and the cooling keeps temperatures impressively low. The 88/100 user sentiment score from our review analysis confirms owners are happy with the purchase. The main things to weigh are the physical size, the noise under load, and the mediocre compute performance. For pure gaming, this is one of the best values in the current market when priced right.
