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 $2,417 BRL, $943 BRL less than the GeForce GTX 1080 Ti at $3,360 BRL. Because it's both faster and competitively priced, the GeForce GTX 1080 Ti wins on performance-per-dollar by about 11%. The GeForce GTX 1660 Ti still sits about $2,138 BRL above its $279 BRL MSRP. The GeForce GTX 1080 Ti still sits about $2,661 BRL above its $699 BRL 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?
The GeForce GTX 1080 Ti 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 Ti if you find it at a steep discount.
