I've said it before, but TSMC's 12nm in practice doesn't appear to be much more than a refinement of its 16nm tech-what Intel would have called 16nm+. Transistor counts increased from 4.4 billion to 6.6 billion, and die size also went up from 200mm^2 to 284mm^2. Perhaps more interesting is when you look at the GPU and compare it with the GP106 used in the GTX 1060. The GPU at the heart of the GTX 1660 is the same TU116 as in the 1660 Ti, only with two of the SMs disabled, which in turn disables 128 CUDA cores and 8 texture units. If you're using such a card, the 1660 is a great upgrade, while anyone with a GTX 970 or better will probably want to wait a bit longer (or go with a faster and more expensive GPU like the GeForce RTX 2060). That's why I generally recommend trying to skip a generation or two of hardware between upgrades, especially for budget and mainstream gamers, which means the GTX 1660 is better positioned as a replacement for an old GTX 960 or earlier GPU. The GTX 1660 will be faster than the GTX 1060 6GB-it has some architectural enhancements, higher clockspeeds, and more shader cores-but it's not going to be a massive upgrade. Getting more performance at a lower price is great, but with graphics cards there's always a problem of competing with the previous generation.
