Radeon RX 6800 vs Radeon RX 6600: In-Depth Breakdown
Performance: Radeon RX 6800 vs Radeon RX 6600
The Radeon RX 6800 is dramatically faster, around 94% ahead of the Radeon RX 6600. That gap is enough to move it up a tier: the Radeon RX 6800 is comfortable at 1440p, while the Radeon RX 6600 is better matched to 1080p. The Radeon RX 6800 packs 3,840 stream processors versus 1,792 on the Radeon RX 6600. The Radeon RX 6800 also has more RT cores (60 vs 28), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
The Radeon RX 6600 currently lists from $550 GBP, $349 GBP less than the Radeon RX 6800 at $899 GBP. Because it's both faster and competitively priced, the Radeon RX 6800 wins on performance-per-dollar by about 19%. The Radeon RX 6600 still sits about $220 GBP above its $330 GBP MSRP. The Radeon RX 6800 still sits about $320 GBP above its $579 GBP MSRP.
Power & Efficiency
On power, the Radeon RX 6600 is the gentler choice at 132W versus 250W. The Radeon RX 6800 is more efficient per watt because it's faster, but its higher 250W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 6800 carries 16GB versus 8GB on the Radeon RX 6600. 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's memory is also faster — 512 GB/s versus 224 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 or Radeon RX 6800?
The Radeon RX 6800 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 if you find it at a steep discount.
