Price & Value
On price, expect to pay $200 GBP for the Radeon RX 6600 versus $420 GBP for the Radeon RX 7700 XT. Because it's both faster and competitively priced, the Radeon RX 7700 XT wins on performance-per-dollar. The Radeon RX 6600 is trading below its $330 GBP MSRP — a genuine deal. The Radeon RX 7700 XT is trading below its $449 GBP MSRP — a genuine deal.
Power & Efficiency
The Radeon RX 6600 pulls less power (132W vs 245W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7700 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 12GB against 8GB, the Radeon RX 7700 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600's 8GB can fall short. The Radeon RX 7700 XT's memory is also faster — 432 GB/s versus 224 GB/s (192-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 7700 XT is roughly 2 years newer than the Radeon RX 6600 (RDNA 3 vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 6600 or Radeon RX 7700 XT?
The Radeon RX 7700 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 if you find it at a steep discount.
