GeForce RTX 3070 vs GeForce GTX 1080 Ti: In-Depth Breakdown
Performance: GeForce RTX 3070 vs GeForce GTX 1080 Ti
The GeForce RTX 3070 is dramatically faster, around 40% ahead of the GeForce GTX 1080 Ti. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the GeForce GTX 1080 Ti is better matched to 1080p. The GeForce RTX 3070 packs 5,888 CUDA cores versus 3,584 on the GeForce GTX 1080 Ti.
Price & Value
The GeForce GTX 1080 Ti currently lists from $227 GBP, $69 GBP less than the GeForce RTX 3070 at $297 GBP. Because it's both faster and competitively priced, the GeForce RTX 3070 wins on performance-per-dollar by about 7%. The GeForce GTX 1080 Ti is trading below its $699 GBP MSRP — a genuine deal. The GeForce RTX 3070 is trading below its $499 GBP MSRP — a genuine deal.
Power & Efficiency
At 220W against 250W, the GeForce RTX 3070 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce GTX 1080 Ti carries 11GB versus 8GB on the GeForce RTX 3070. The extra 3GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce GTX 1080 Ti's memory is also faster — 484 GB/s versus 448 GB/s (352-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 3070 is roughly 3 years newer than the GeForce GTX 1080 Ti (Ampere vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1080 Ti or GeForce RTX 3070?
The GeForce RTX 3070 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 GTX 1080 Ti if you find it at a steep discount.
