GeForce RTX 2080 vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce RTX 2080 vs GeForce GTX 1660
The GeForce RTX 2080 is dramatically faster, around 90% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the GeForce RTX 2080 is comfortable at 1080p, while the GeForce GTX 1660 is better matched to entry-level 1080p. The GeForce RTX 2080 packs 2,944 CUDA cores versus 1,408 on the GeForce GTX 1660.
Price & Value
The GeForce GTX 1660 currently lists from $268 EUR, $852 EUR less than the GeForce RTX 2080 at $1,120 EUR. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~120% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 2080 still sits about $421 EUR above its $699 EUR MSRP.
Power & Efficiency
On power, the GeForce GTX 1660 is the gentler choice at 120W versus 225W. The GeForce RTX 2080 is more efficient per watt because it's faster, but its higher 225W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The GeForce RTX 2080 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 RTX 2080's memory is also faster — 448 GB/s versus 192 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce GTX 1660 or GeForce RTX 2080?
Choose the GeForce RTX 2080 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.
