GeForce GTX 1080 vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce GTX 1080 vs GeForce GTX 1660
The GeForce GTX 1080 is significantly faster, around 30% ahead of the GeForce GTX 1660. Both cards sit in the same broad class, well suited to entry-level 1080p. The GeForce GTX 1080 packs 2,560 CUDA cores versus 1,408 on the GeForce GTX 1660.
Price & Value
The GeForce GTX 1080 currently lists from $183 EUR, $243 EUR less than the GeForce GTX 1660 at $427 EUR. Because it's both faster and competitively priced, the GeForce GTX 1080 wins on performance-per-dollar by about 202%. The GeForce GTX 1080 is trading below its $599 EUR MSRP — a genuine deal. The GeForce GTX 1660 still sits about $208 EUR above its $219 EUR MSRP.
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?
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 if you find it at a steep discount.
