GeForce RTX 3090 vs Radeon RX 6800M: In-Depth Breakdown
Performance: GeForce RTX 3090 vs Radeon RX 6800M
The GeForce RTX 3090 is dramatically faster, around 44% ahead of the Radeon RX 6800M. Both cards sit in the same broad class, well suited to 1440p.
Power & Efficiency
The Radeon RX 6800M draws just 145W versus 350W for the GeForce RTX 3090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 2 architecture on a TSMC 7nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 24GB against 12GB, the GeForce RTX 3090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6800M's 12GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 3090 brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6800M 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 3090 or Radeon RX 6800M?
The GeForce RTX 3090 is the faster card by about 44%. 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.
