GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti
The GeForce GTX 1070 Ti is noticeably faster, around 9% ahead of the GeForce GTX 1660 Ti. Both cards sit in the same broad class, well suited to entry-level 1080p. The GeForce GTX 1070 Ti packs 2,432 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Price & Value
On price, expect to pay $2,898 BRL for the GeForce GTX 1660 Ti versus $6,530 BRL for the GeForce GTX 1070 Ti. Despite being slower, the GeForce GTX 1660 Ti offers the better performance-per-dollar (~107% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 Ti still sits about $2,619 BRL above its $279 BRL MSRP. The GeForce GTX 1070 Ti still sits about $6,081 BRL above its $449 BRL MSRP.
Power & Efficiency
The GeForce GTX 1660 Ti draws just 120W versus 180W for the GeForce GTX 1070 Ti, 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 Ti has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 Ti's 6GB can fall short. The GeForce GTX 1660 Ti's memory is also faster — 288 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 Ti is roughly 2 years newer than the GeForce GTX 1070 Ti (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1070 Ti or GeForce GTX 1660 Ti?
Choose the GeForce GTX 1070 Ti if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 Ti stretches your money further for only slightly lower performance.
