Looking at the long history of Nvidia GPUs here:
https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units
The closest "equivalents" are likely the GT 1030 and GTX 1630.
Yep, I knew that. As you pointed out earlier, these low end GPUs (GT equivalents) have gone out of production pretty much altogether. However, they can still be found in the used markets.GTX 1630 are out of production, so GTX 1650 are actually cheaper. Though even when new they weren't cheaper than 1650, especially used.
Is this for use with the Athlon system you asked about in another thread?What is MSI N730-2GD3V2 equivalent?
