Price & Value
Right now the Radeon RX 6600 XT starts at $502 GBP against $899 GBP for the Radeon RX 6800. Despite being slower, the Radeon RX 6600 XT offers the better performance-per-dollar (~8% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6600 XT still sits about $123 GBP above its $379 GBP MSRP. The Radeon RX 6800 still sits about $320 GBP above its $579 GBP MSRP.
Power & Efficiency
The Radeon RX 6600 XT pulls less power (160W vs 250W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6800 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 8GB, the Radeon RX 6800 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600 XT's 8GB can fall short. The Radeon RX 6800'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?
Choose the Radeon RX 6800 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6600 XT stretches your money further for only slightly lower performance.
