GeForce RTX 3090 vs GeForce RTX 4070: In-Depth Breakdown
Performance: GeForce RTX 3090 vs GeForce RTX 4070
The GeForce RTX 3090 is marginally faster, around 5% ahead of the GeForce RTX 4070. Both cards sit in the same broad class, well suited to 1440p. The GeForce RTX 3090 packs 10,496 CUDA cores versus 5,888 on the GeForce RTX 4070.
Power & Efficiency
The GeForce RTX 4070 draws just 200W 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 Ada Lovelace architecture on a TSMC N4 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 GeForce RTX 4070's 12GB can fall short. The GeForce RTX 3090's memory is also faster — 936 GB/s versus 504 GB/s (384-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 4070 is roughly 3 years newer than the GeForce RTX 3090 (Ada Lovelace vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3090 or GeForce RTX 4070?
The GeForce RTX 3090 is the faster card. 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.
