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 1660 currently lists from $230 EUR, $305 EUR less than the GeForce GTX 1080 at $535 EUR. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~79% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1080 is trading below its $599 EUR 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.

Frequently Asked Questions

Is the GeForce GTX 1080 better than the GeForce GTX 1660?

The GeForce GTX 1080 is significantly faster, roughly 30% ahead. The GeForce GTX 1660 is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the GeForce GTX 1080 or the GeForce GTX 1660?

Neither is a dedicated 4K card; both are best at entry-level 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the GeForce GTX 1080 worth the extra $305 EUR over the GeForce GTX 1660?

Only if you need the extra performance or features; on pure value the GeForce GTX 1660 comes out ahead.

Does the GeForce GTX 1080 have enough VRAM advantage to matter?

Its 8GB (vs 6GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
