GeForce RTX 5070 vs GeForce RTX 3090: In-Depth Breakdown
Performance: GeForce RTX 5070 vs GeForce RTX 3090
The GeForce RTX 5070 is noticeably faster, around 18% ahead of the GeForce RTX 3090. That gap is enough to move it up a tier: the GeForce RTX 5070 is comfortable at 4K with upscaling and native 1440p, while the GeForce RTX 3090 is better matched to 1440p.
Power & Efficiency
At 250W against 350W, the GeForce RTX 5070 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the GeForce RTX 3090 at 24GB versus 12GB on the GeForce RTX 5070 — that extra 12GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. The GeForce RTX 3090's memory is also faster — 936 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 5 years newer than the GeForce RTX 3090 (Blackwell 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 5070?
The GeForce RTX 5070 is the faster card by about 18%. 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.
