XFX Radeon RX 6700 XT Speedster 12GB GDDR6 Black

The XFX MERC319 RX 6700 XT nails cooling with a 92nd percentile thermal ranking and whisper-quiet fans, but its 46th percentile raster performance is just average. At $780, the 35th percentile affordability ranking stings. Great cooler, mid-range chipset, questionable price.

The 19,730 PassMark score puts this card in the 46th percentile for raster performance, which is about average for our database. That translates to solid 1440p gaming, and several owners report surprisingly good 4K results in less demanding titles. The 2,622MHz boost clock is a decent factory overclock, and the 12GB of VRAM gives you headroom for texture-heavy games that would choke an 8GB card.

Ray tracing is a mixed bag. The 62nd percentile RT ranking means it's above average for AMD's RDNA 2 generation, but you're not going to max out Cyberpunk with RT on and expect smooth frames. The 26.43 FP16 TFLOPS of compute power lands in the 20th percentile overall, which is a weak spot if you're doing anything beyond gaming. But for pure gaming, the 384 GB/s of memory bandwidth keeps things moving. The thermal performance is the standout here, 92nd percentile means this card stays cool and quiet, which owners confirm is the MERC319's biggest strength.

Stacked against the current competition, this card is in a tough spot. The ASUS PRIME RTX 5080 and Gigabyte AERO RTX 5080 absolutely demolish it in raw performance, though they're in a completely different price bracket. The MSI Ventus RTX 5070 Ti and ZOTAC APOCALYPSE RTX 5080 also outclass it significantly. Even the Sapphire NITRO+ 11322-01-40G, another AMD option, offers better overall performance. Where the XFX holds its own is cooling, that 92nd percentile thermal ranking beats most cards at any price. But the 46th percentile raster score means you're getting mid-range performance at a price that's creeping toward high-end territory. The 12GB of VRAM is a genuine advantage over 8GB cards in this class, but it's not enough to close the gap with newer architectures.

At $780 USD from the single US listing we track, this card sits in the 35th percentile for affordability. That's rough. You're paying a premium for the MERC319's excellent cooling solution, but the underlying RX 6700 XT chipset is a mid-range performer from 2021. The 12GB of VRAM helps justify the price somewhat, and the thermal performance means you're getting a card that will run cool and quiet for years. But when owners themselves are saying it's overpriced in the current market, that's a signal worth listening to. If you can find this card on sale or used at a reasonable price, the value equation changes dramatically.

The XFX Speedster MERC319 RX 6700 XT posts a PassMark G3D score of 19,730, which lands it right around the middle of the pack for raster performance in our database. That's not a headline-grabbing number in 2025, but it's still plenty for 1440p gaming at high settings. The real story here is the cooling. This card sits in the 92nd percentile for thermals, and owners consistently mention how quiet the triple-fan setup runs even under load.

You're getting 12GB of GDDR6 on a 192-bit bus with 384 GB/s of bandwidth, plus 40 ray tracing cores and a 2,622MHz boost clock. The 230W TDP means you'll want a decent power supply, and at 323mm long and three slots thick, it's a chunky card that won't fit in every case. The 4.3-star average across 111 reviews tells you most buyers are happy, but there are some reliability concerns worth digging into.

Skip this card if you're doing anything beyond gaming. The 20th percentile compute ranking means AI workloads, rendering, and other GPU-accelerated tasks will feel sluggish. Also skip it if you're building in a small form factor case, the 323mm length and 3-slot design rule out most compact builds. And if you're price-sensitive, the 35th percentile affordability ranking means you're paying a premium for the cooling solution rather than raw performance. The 230W TDP also means you'll need a beefier power supply than some competing cards require.

The XFX Speedster MERC319 RX 6700 XT is a well-built card with exceptional cooling, but it's fighting against its own price tag. The 92nd percentile thermal performance and quiet operation are genuinely impressive, and the 12GB of VRAM gives it legs for 1440p gaming. But the 46th percentile raster score and 35th percentile affordability ranking make it hard to recommend at $780. If you're building a quiet, cool-running 1440p rig and you find this card at a discount, it's a solid buy. At full price, you're paying a premium for cooling excellence on a mid-range chipset. The 4.3-star owner rating suggests most buyers are happy, but the stuttering issues reported by some owners are a concern worth considering.
