For comparison, the GTX 1650 has a MSRP of $149 and the GeForce GTX 1660 costs $229. There's a pretty big gap between these two cards and the GTX 1660 is about 13 percent faster on average than the RX 580.
The GTX 1650 Ti is believed to be based on a new TU117 variant with 1024 CUDA cores, 32 ROPs, and 64 TMUs, in combination with a 128-bit memory bus and 4GB GDDR5 memory clocked at 8000MHz. This results in memory bandwidth of 128GB/s.
In terms of power efficiency, the difference between the GTX 1650 Ti and the RX 580 will be massive:
Should NVIDIA be able to pull the feat of keeping the same 75W TDP between its Ti and non-Ti GTX 1650 (as it did with the GTX 1660), that could mean that a 75 W graphics card would be contending with AMD's 185W RX 580 - a mean, green feet in the power efficiency arena.Via: TPU
