GeForce RTX 4090 vs GeForce RTX 5070: In-Depth Breakdown
Performance: GeForce RTX 4090 vs GeForce RTX 5070
The GeForce RTX 4090 is dramatically faster, around 57% ahead of the GeForce RTX 5070. That gap is enough to move it up a tier: the GeForce RTX 4090 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 5070 is better matched to 4K with upscaling and native 1440p. The GeForce RTX 4090 packs 16,384 CUDA cores versus 6,144 on the GeForce RTX 5070.
Power & Efficiency
The GeForce RTX 5070 draws just 250W 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. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
With 24GB against 12GB, the GeForce RTX 4090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 5070's 12GB can fall short. The GeForce RTX 4090's memory is also faster — 1,008 GB/s versus 672 GB/s (384-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 5070 is roughly 3 years newer than the GeForce RTX 4090 (Blackwell vs Ada Lovelace), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 5070 or GeForce RTX 4090?
The GeForce RTX 4090 is the faster card by about 57%. 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.
