It is close to TU116 .
Lets take Overwatch as an example.
AMD tested RX 5500 with RX 3600X CPU, and 3200 MHz RAM. What this means?
With the same config, GTX 1660 Ti averages 140 FPS in Overwatch 1080p, Epic presets, On some maps its higher, on some maps its lower, on some maps it nails this point. Overall - average it is 140 FPS.
RX 5500 in the same settings, same preset, same CPU, averaged, according to AMD 135 FPS.
You canexpect that with Intel CPU, both of those GPU will get 150 FPS, or higher(GTX 1660 Ti averages actually 155 FPS in Overwatch, 1080p, Epic preset with 9400F CPU).
AMD undersold their product, once again .
