In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6150 SE 256MB are massively better than the Nvidia GeForce GTX 1650 Super Gainward Pegasus 4GB.

The GTX 1650 was released over three years more recently than the 6150 SE, and so the GTX 1650 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 6150 SE when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GTX 1650 has 3840 MB more video memory than the 6150 SE, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 1650 also has superior memory performance overall.

The GTX 1650 has 256 GB/sec greater memory bandwidth than the 6150 SE, which means that the memory performance of the GTX 1650 is massively better than the 6150 SE.

The GeForce GTX 1650 Super Gainward Pegasus 4GB has 1280 Shader Processing Units and the GeForce 6150 SE 256MB has 2. However, the actual shader performance of the GTX 1650 is 2208 and the actual shader performance of the 6150 SE is 1. The GTX 1650 having 2207 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 1650 delivers a massively smoother and more efficient experience when processing graphical data than the 6150 SE.

The GeForce GTX 1650 Super Gainward Pegasus 4GB requires 100 Watts to run but there is no entry for the GeForce 6150 SE 256MB. We would recommend a PSU with at least 350 Watts for the GTX 1650.
