GeForce GTX 1080 vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce GTX 1080 vs GeForce GTX 1660
The GeForce GTX 1080 is dramatically faster, around 45% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the GeForce GTX 1080 is comfortable at 1080p, while the GeForce GTX 1660 is better matched to entry-level 1080p. The GeForce GTX 1080 packs 2,560 CUDA cores versus 1,408 on the GeForce GTX 1660.
Price & Value
The GeForce GTX 1660 currently lists from $59 GBP, $101 GBP less than the GeForce GTX 1080 at $160 GBP. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~87% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 is trading below its $219 GBP MSRP — a genuine deal. The GeForce GTX 1080 is trading below its $599 GBP MSRP — a genuine deal.
Power & Efficiency
At 120W against 180W, the GeForce GTX 1660 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. 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 192 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 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?
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 stretches your money further for only slightly lower performance.
