Performance: Radeon RX 6800 XT vs Radeon RX 6600 XT
The Radeon RX 6800 XT is dramatically faster, around 100% ahead of the Radeon RX 6600 XT. That gap is enough to move it up a tier: the Radeon RX 6800 XT is comfortable at 1440p, while the Radeon RX 6600 XT is better matched to 1080p. The Radeon RX 6800 XT packs 4,608 stream processors versus 2,048 on the Radeon RX 6600 XT. The Radeon RX 6800 XT also has more RT cores (72 vs 32), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
The Radeon RX 6600 XT currently lists from $502 GBP, $334 GBP less than the Radeon RX 6800 XT at $836 GBP. Because it's both faster and competitively priced, the Radeon RX 6800 XT wins on performance-per-dollar by about 20%. The Radeon RX 6600 XT still sits about $123 GBP above its $379 GBP MSRP. The Radeon RX 6800 XT still sits about $187 GBP above its $649 GBP MSRP.
Power & Efficiency
On power, the Radeon RX 6600 XT is the gentler choice at 160W versus 300W. The Radeon RX 6800 XT is more efficient per watt because it's faster, but its higher 300W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 6800 XT carries 16GB versus 8GB on the Radeon RX 6600 XT. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Radeon RX 6800 XT's memory is also faster — 512 GB/s versus 256 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 6600 XT or Radeon RX 6800 XT?
The Radeon RX 6800 XT is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 6600 XT if you find it at a steep discount.
