GeForce RTX 5070 vs GeForce RTX 3090 Ti: In-Depth Breakdown
Performance: GeForce RTX 5070 vs GeForce RTX 3090 Ti
The GeForce RTX 5070 is marginally faster, around 4% ahead of the GeForce RTX 3090 Ti. Both cards sit in the same broad class, well suited to 4K with upscaling and native 1440p.
Price & Value
The GeForce RTX 5070 currently lists from $539 GBP, $925 GBP less than the GeForce RTX 3090 Ti at $1,464 GBP. Because it's both faster and competitively priced, the GeForce RTX 5070 wins on performance-per-dollar by about 184%. The GeForce RTX 3090 Ti is trading below its $1,999 GBP MSRP — a genuine deal.
Power & Efficiency
At 250W against 450W, 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 Ti 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 Ti'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 3090 Ti (Blackwell vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3090 Ti 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 Ti if you find it at a steep discount.
