GeForce GTX 1070 Laptop vs GeForce GTX 1660 Ti Laptop: In-Depth Breakdown
Performance: GeForce GTX 1070 Laptop vs GeForce GTX 1660 Ti Laptop
The GeForce GTX 1070 Laptop is noticeably faster, around 9% ahead of the GeForce GTX 1660 Ti Laptop. Both cards sit in the same broad class, well suited to entry-level 1080p. The GeForce GTX 1070 Laptop packs 2,048 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti Laptop.
Power & Efficiency
The GeForce GTX 1660 Ti Laptop sips power at 80W next to the GeForce GTX 1070 Laptop's 115W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce GTX 1070 Laptop's 8GB (vs 6GB on the GeForce GTX 1660 Ti Laptop) gives it more room for 4K textures and memory-hungry creative or AI workloads. The GeForce GTX 1660 Ti Laptop'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 Laptop is roughly 3 years newer than the GeForce GTX 1070 Laptop (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1070 Laptop or GeForce GTX 1660 Ti Laptop?
