GeForce RTX 2080 Ti vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce RTX 2080 Ti vs GeForce GTX 1660 Ti
The GeForce RTX 2080 Ti is dramatically faster, around 127% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the GeForce RTX 2080 Ti is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p. The GeForce RTX 2080 Ti packs 4,352 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Price & Value
The GeForce GTX 1660 Ti currently lists from $32,350 JPY, $21,010 JPY less than the GeForce RTX 2080 Ti at $53,360 JPY. Because it's both faster and competitively priced, the GeForce RTX 2080 Ti wins on performance-per-dollar by about 38%. The GeForce GTX 1660 Ti still sits about $32,071 JPY above its $279 JPY MSRP. The GeForce RTX 2080 Ti still sits about $52,361 JPY above its $999 JPY MSRP.
Power & Efficiency
On power, the GeForce GTX 1660 Ti is the gentler choice at 120W versus 250W. The GeForce RTX 2080 Ti is more efficient per watt because it's faster, but its higher 250W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The GeForce RTX 2080 Ti carries 11GB versus 6GB on the GeForce GTX 1660 Ti. The extra 5GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 2080 Ti's memory is also faster — 616 GB/s versus 288 GB/s (352-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce GTX 1660 Ti or GeForce RTX 2080 Ti?
The GeForce RTX 2080 Ti 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.
