GeForce RTX 4090 vs Radeon RX 6700M: In-Depth Breakdown
Performance: GeForce RTX 4090 vs Radeon RX 6700M
The GeForce RTX 4090 is dramatically faster, around 213% ahead of the Radeon RX 6700M. That gap is enough to move it up a tier: the GeForce RTX 4090 is comfortable at 4K and high-refresh 1440p, while the Radeon RX 6700M is better matched to 1080p.
Price & Value
Right now the Radeon RX 6700M starts at $2,335 GBP against $4,262 GBP for the GeForce RTX 4090. The GeForce RTX 4090 still sits about $2,663 GBP above its $1,599 GBP MSRP.
Power & Efficiency
The Radeon RX 6700M draws just 135W versus 450W for the GeForce RTX 4090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 24GB against 10GB, the GeForce RTX 4090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6700M's 10GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 4090 brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6700M 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 4090 or Radeon RX 6700M?
The GeForce RTX 4090 is the faster card by about 213%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
