GeForce GTX 1070 Ti vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce GTX 1070 Ti vs GeForce GTX 1660
The GeForce GTX 1070 Ti is significantly faster, around 27% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the GeForce GTX 1070 Ti is comfortable at 1080p, while the GeForce GTX 1660 is better matched to entry-level 1080p. The GeForce GTX 1070 Ti packs 2,432 CUDA cores versus 1,408 on the GeForce GTX 1660.
Price & Value
Right now the GeForce GTX 1660 starts at $59 GBP against $181 GBP for the GeForce GTX 1070 Ti. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~141% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 is trading below its $219 GBP MSRP — a genuine deal. The GeForce GTX 1070 Ti is trading below its $449 GBP MSRP — a genuine deal.
Power & Efficiency
The GeForce GTX 1660 draws just 120W versus 180W for the GeForce GTX 1070 Ti, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 6GB, the GeForce GTX 1070 Ti has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660's 6GB can fall short. The GeForce GTX 1070 Ti's memory is also faster — 256 GB/s versus 192 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce GTX 1660 is roughly 2 years newer than the GeForce GTX 1070 Ti (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1660 or GeForce GTX 1070 Ti?
Choose the GeForce GTX 1070 Ti if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 stretches your money further for only slightly lower performance.
