GeForce RTX 3070 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce RTX 3070 vs GeForce GTX 1660 Ti
The GeForce RTX 3070 is dramatically faster, around 145% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p. The GeForce RTX 3070 packs 5,888 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Price & Value
The GeForce GTX 1660 Ti currently lists from $53,717 JPY, $19,813 JPY less than the GeForce RTX 3070 at $73,530 JPY. Because it's both faster and competitively priced, the GeForce RTX 3070 wins on performance-per-dollar by about 79%. The GeForce GTX 1660 Ti still sits about $53,438 JPY above its $279 JPY MSRP. The GeForce RTX 3070 still sits about $73,031 JPY above its $499 JPY MSRP.
Power & Efficiency
On power, the GeForce GTX 1660 Ti is the gentler choice at 120W versus 220W. The GeForce RTX 3070 is more efficient per watt because it's faster, but its higher 220W draw means more heat and a bigger PSU. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the GeForce RTX 3070 at 8GB versus 6GB on the GeForce GTX 1660 Ti — that extra 2GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. The GeForce RTX 3070's memory is also faster — 448 GB/s versus 288 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 Ti or GeForce RTX 3070?
The GeForce RTX 3070 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.
