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.
Price & Value
On price, expect to pay $15,800 JPY for the GeForce GTX 1070 versus $42,243 JPY for the GeForce GTX 1660 SUPER. Because it's both faster and competitively priced, the GeForce GTX 1070 wins on performance-per-dollar by about 167%. The GeForce GTX 1070 still sits about $15,421 JPY above its $379 JPY MSRP. The GeForce GTX 1660 SUPER still sits about $42,014 JPY above its $229 JPY MSRP.
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 all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX 1660 SUPER if you find it at a steep discount.
