Because it's both faster and competitively priced, the Radeon RX 6900 XT wins on performance-per-dollar by about 141%. The Radeon RX 6900 XT is trading below its $999 GBP MSRP — a genuine deal. The Radeon RX 5700 XT still sits about $362 GBP above its $399 GBP MSRP.
Power & Efficiency
The Radeon RX 5700 XT pulls less power (225W vs 300W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6900 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 2 architecture on a TSMC N7 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 16GB against 8GB, the Radeon RX 6900 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 5700 XT's 8GB can fall short. The Radeon RX 6900 XT's memory is also faster — 512 GB/s versus 448 GB/s — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 5700 XT or Radeon RX 6900 XT?
The Radeon RX 6900 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 5700 XT if you find it at a steep discount.
