Nvidia gtx 1660 ti vs amd rx 580
With 6GB GDDR5 memory capacity, memory bandwidth is reduced by 33%. The
has a bigger gap in speed. The 12Gbps of the Ti card is much faster than the 8Gbps of the 1660, which makes up for the deficiencies of the CUDA core to a certain extent. In this case, Super surpassed both graphics cards with a maximum speed of 14 Gbps.
Of course, it depends on the settings you use and the quality of the resolution, but you will notice some changes when using either of these two GPUs for gaming, and the GTX 1660 lags behind the 1660 Ti between 10 and 10. Between 25%.

But compared to GTX 1660, is the Ti nickname worth the extra money? If you can afford it, then yes. You get several stream multiprocessors and 128 CUDA cores from your architecture. The memory drop can be said to be the biggest drop of GTX 1660.
