GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti
The GeForce GTX 1070 Ti is marginally faster, around 8% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the GeForce GTX 1070 Ti is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p. The GeForce GTX 1070 Ti packs 2,432 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Power & Efficiency
The GeForce GTX 1660 Ti 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 Ti's 6GB can fall short. The GeForce GTX 1660 Ti's memory is also faster — 288 GB/s versus 256 GB/s (192-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce GTX 1660 Ti 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.
