GeForce GTX 1070 Laptop vs GeForce GTX 1660 Laptop: In-Depth Breakdown
Performance: GeForce GTX 1070 Laptop vs GeForce GTX 1660 Laptop
The GeForce GTX 1070 Laptop is significantly faster, around 33% ahead of the GeForce GTX 1660 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 1,408 on the GeForce GTX 1660 Laptop.
Price & Value
On price, expect to pay $450 GBP for the GeForce GTX 1660 Laptop versus $1,899 GBP for the GeForce GTX 1070 Laptop.
Power & Efficiency
The GeForce GTX 1660 Laptop draws just 80W versus 115W for the GeForce GTX 1070 Laptop, 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 Laptop has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 Laptop's 6GB can fall short. The GeForce GTX 1070 Laptop'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 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.
