GeForce GTX 1080 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce GTX 1080 vs GeForce GTX 1660 Ti
The GeForce GTX 1080 is significantly faster, around 18% ahead of the GeForce GTX 1660 Ti. Both cards sit in the same broad class, well suited to entry-level 1080p. The GeForce GTX 1080 packs 2,560 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Price & Value
The GeForce GTX 1660 Ti currently lists from $426 EUR, $311 EUR less than the GeForce GTX 1080 at $737 EUR. Despite being slower, the GeForce GTX 1660 Ti offers the better performance-per-dollar (~46% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 Ti still sits about $147 EUR above its $279 EUR MSRP. The GeForce GTX 1080 still sits about $138 EUR above its $599 EUR MSRP.
Power & Efficiency
At 120W against 180W, the GeForce GTX 1660 Ti is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the GeForce GTX 1080 at 8GB versus 6GB on the GeForce GTX 1660 Ti — that extra 2GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. The GeForce GTX 1080's memory is also faster — 320 GB/s versus 288 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 Ti is roughly 3 years newer than the GeForce GTX 1080 (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1080 or GeForce GTX 1660 Ti?
Choose the GeForce GTX 1080 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.
