GeForce RTX 4070 SUPER vs Radeon RX 6900 XT: In-Depth Breakdown
Performance: GeForce RTX 4070 SUPER vs Radeon RX 6900 XT
The GeForce RTX 4070 SUPER and Radeon RX 6900 XT post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to 4K with upscaling and native 1440p gaming.
Price & Value
Right now the Radeon RX 6900 XT starts at $700 GBP against $719 GBP for the GeForce RTX 4070 SUPER. Despite being slower, the Radeon RX 6900 XT offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The Radeon RX 6900 XT is trading below its $999 GBP MSRP — a genuine deal. The GeForce RTX 4070 SUPER still sits about $120 GBP above its $599 GBP MSRP.
Power & Efficiency
The GeForce RTX 4070 SUPER draws just 220W versus 300W for the Radeon RX 6900 XT, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Ada Lovelace architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 16GB against 12GB, the Radeon RX 6900 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 4070 SUPER's 12GB can fall short.
Generation & Longevity
The GeForce RTX 4070 SUPER is roughly 4 years newer than the Radeon RX 6900 XT (Ada Lovelace vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 4070 SUPER brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6900 XT offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce RTX 4070 SUPER or Radeon RX 6900 XT?
Choose the GeForce RTX 4070 SUPER if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6900 XT stretches your money further for near-identical performance.
