Price & Value
Right now the Radeon RX 9070 starts at $500 GBP against $633 GBP for the Radeon RX 7900 XT. Despite being slower, the Radeon RX 9070 offers the better performance-per-dollar (~20% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 9070 is trading below its $549 GBP MSRP — a genuine deal. The Radeon RX 7900 XT is trading below its $899 GBP MSRP — a genuine deal.
Power & Efficiency
The Radeon RX 9070 draws just 220W versus 300W for the Radeon RX 7900 XT, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 4 architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 20GB against 16GB, the Radeon RX 7900 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 9070's 16GB can fall short. The Radeon RX 7900 XT's memory is also faster — 800 GB/s versus 645 GB/s (320-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 9070 is roughly 3 years newer than the Radeon RX 7900 XT (RDNA 4 vs RDNA 3), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 7900 XT or Radeon RX 9070?
Choose the Radeon RX 7900 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 9070 stretches your money further for only slightly lower performance.
