GeForce GTX 1070 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: GeForce GTX 1070 vs GeForce GTX 1660 SUPER
The GeForce GTX 1070 and GeForce GTX 1660 SUPER post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to entry-level 1080p gaming. The GeForce GTX 1070 packs 1,920 CUDA cores versus 1,408 on the GeForce GTX 1660 SUPER.
Power & Efficiency
The GeForce GTX 1660 SUPER draws just 125W versus 150W for the GeForce GTX 1070, 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 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 SUPER's 6GB can fall short. The GeForce GTX 1660 SUPER's memory is also faster — 336 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 SUPER is roughly 3 years newer than the GeForce GTX 1070 (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1070 or GeForce GTX 1660 SUPER?
The GeForce GTX 1070 is the faster card. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
