GeForce GTX 1080 Ti vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce GTX 1080 Ti vs GeForce GTX 1660 Ti
The GeForce GTX 1080 Ti is dramatically faster, around 55% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the GeForce GTX 1080 Ti is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p. The GeForce GTX 1080 Ti packs 3,584 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Price & Value
The GeForce GTX 1660 Ti currently lists from $421 EUR, $583 EUR less than the GeForce GTX 1080 Ti at $1,004 EUR. Despite being slower, the GeForce GTX 1660 Ti offers the better performance-per-dollar (~54% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 Ti still sits about $142 EUR above its $279 EUR MSRP. The GeForce GTX 1080 Ti still sits about $305 EUR above its $699 EUR MSRP.
Power & Efficiency
At 120W against 250W, 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
The GeForce GTX 1080 Ti carries 11GB versus 6GB on the GeForce GTX 1660 Ti. The extra 5GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce GTX 1080 Ti's memory is also faster — 484 GB/s versus 288 GB/s (352-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 2 years newer than the GeForce GTX 1080 Ti (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1080 Ti or GeForce GTX 1660 Ti?
Choose the GeForce GTX 1080 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.
