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 23% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the GeForce GTX 1080 is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched 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 1080 currently lists from $160 GBP, $178 GBP less than the GeForce GTX 1660 Ti at $339 GBP. Because it's both faster and competitively priced, the GeForce GTX 1080 wins on performance-per-dollar by about 160%. The GeForce GTX 1080 is trading below its $599 GBP MSRP — a genuine deal.
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
The GeForce GTX 1080 carries 8GB versus 6GB on the GeForce GTX 1660 Ti. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. 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?
The GeForce GTX 1080 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.
