XFX Radeon RX 7900 XTX SPEEDSTER MERC310 24GB GDDR6
The 24GB GDDR6 frame buffer and 384-bit memory bus make this RDNA 3 card a strong choice for high-resolution texture packs and AI workloads, scoring 70.9 for AI/LLM tasks. Its triple-fan cooler and 2.9-slot design prioritize sustained thermal performance under the 327W TDP. This GPU is best for 4K gamers and AI hobbyists who need massive VRAM without stepping up to a professional workstation card.
Resumen
The 30-Second Version
The XFX 7900 XTX MERC310 is a 4K raster monster with 24GB of VRAM and a loud stock fan curve. Buy it cheap, set a custom curve, and skip it if you're paying RTX 5080 prices.
Pros & Cons
Ventajas
- 24GB GDDR6 with 960 GB/s bandwidth crushes 4K texture loads 96th
- Top-tier compute and AI performance for the price 95th
- Triple fan cooler keeps temps in check once you set a custom curve 95th
- 3x DP 2.1 plus HDMI 2.1 gives you real next-gen display options 92nd
Desventajas
- Default fan curve is loud and pointless
- Stock BIOS blocks undervolting and overclocking
- 344mm long and nearly 3 slots, check your case clearance
- Efficiency is mid-pack at best

Las pruebas
Performance
What surprised us most is how this thing lands in the 99th percentile for compute while still holding a 92nd percentile ray tracing score. That's a combo you don't see often. The 960 GB/s memory bandwidth and 24GB frame buffer mean 4K textures load fast and stay loaded. But the default fan curve is unnecessarily aggressive, and the stock BIOS locks out undervolting, which is a weird choice for a card this thirsty at 327W TDP.

vs Competition
Against the ASUS ProArt RTX 5080 and Gigabyte AERO RTX 5080, the XFX wins on raw VRAM and compute but loses on efficiency and feature polish. The MSI Ventus RTX 5070 Ti is cheaper but gives up 8GB of VRAM and a chunk of raster performance. If you want pure 4K raster and AI workloads without DLSS dependency, the XFX is the pick. If you care about ray tracing and power draw, the RTX 5080 cards are better rounded.

Overview
The XFX Radeon RX 7900 XTX SPEEDSTER MERC310 is a monster of a card that sits at the top of our compute charts. It's got 24GB of GDDR6 on a 384-bit bus, 6144 stream processors, and enough raw FP32 grunt (61.39 TFLOPS) to make 4K gaming feel almost casual. The one thing to know? This is the card you buy when you want flagship AMD raster performance without paying RTX 5090 money.
Common Questions
Q: Will this fit in my case?
It's 344mm long and nearly 3 slots thick. Measure your case before you buy. If you've got a compact mid-tower, you might need to remove a drive cage or look at a smaller card.
Q: Can I undervolt or overclock this card?
Not on the stock BIOS. XFX locked it down. You can set a custom fan curve, but if you want voltage control you'll need to flash a different BIOS or look at another model.
Q: Is 24GB of VRAM overkill?
For 1440p, yes. For 4K with high-res texture packs and AI workloads, no. It's future-proofing that actually pays off if you keep cards for 3-4 years.
Who Should Skip This
If you're building a small form factor rig or you care about power efficiency, this isn't your card. It's huge, it's thirsty, and the stock fan curve is obnoxious. Go grab an RTX 5070 Ti or a more compact 7900 XTX variant instead.
Verdict
Buy it if you find it under USD 1,100 or CAD 1,200 and you want a 4K raster beast with 24GB of VRAM. Set a custom fan curve, accept the locked BIOS, and enjoy the frames. If you're paying more than that, get an RTX 5080 instead.
