GeForce GTX 1070 Laptop vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce GTX 1070 Laptop vs GeForce GTX 1660
The GeForce GTX 1070 Laptop is significantly faster, around 20% ahead of the GeForce GTX 1660. 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.
VRAM & Future-Proofing
The GeForce GTX 1070 Laptop carries 8GB versus 6GB on the GeForce GTX 1660. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. 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 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?
The GeForce GTX 1070 Laptop is the faster card by about 20%. Since one of these is a laptop GPU, its listed price covers the whole system rather than just the chip, so it isn't directly comparable — base your decision on the spec differences above.
