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 15% 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.
Price & Value
The GeForce RTX 5070 currently lists from $539 GBP, $680 GBP less than the GeForce RTX 3090 at $1,219 GBP. Because it's both faster and competitively priced, the GeForce RTX 5070 wins on performance-per-dollar by about 159%. The GeForce RTX 3090 is trading below its $1,499 GBP MSRP — a genuine deal.
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
The GeForce RTX 3090 carries 24GB versus 12GB on the GeForce RTX 5070. The extra 12GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. 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 all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce RTX 3090 if you find it at a steep discount.
