GeForce GTX 1070 vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce GTX 1070 vs GeForce GTX 1660
The GeForce GTX 1070 is significantly faster, around 18% ahead of the GeForce GTX 1660. Both cards sit in the same broad class, well suited to entry-level 1080p. The GeForce GTX 1070 packs 1,920 CUDA cores versus 1,408 on the GeForce GTX 1660.
Price & Value
Right now the GeForce GTX 1660 starts at $59 GBP against $158 GBP for the GeForce GTX 1070. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~126% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 is trading below its $219 GBP MSRP — a genuine deal. The GeForce GTX 1070 is trading below its $379 GBP MSRP — a genuine deal.
Power & Efficiency
The GeForce GTX 1660 draws just 120W 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's 6GB can fall short. The GeForce GTX 1070'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 (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?
Choose the GeForce GTX 1070 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 stretches your money further for only slightly lower performance.
