In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 are significantly better than the Nvidia GeForce GTX 1650 Ultra.

The GeForce GTX 1080 has a 197 MHz higher core clock speed and 104 more Texture Mapping Units than the GTX 1650. This results in the GeForce GTX 1080 providing 178.1 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTX 1080 has a 197 MHz higher core clock speed and 32 more Render Output Units than the GTX 1650. This results in the GeForce GTX 1080 providing 57.7 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 1650 was released over three years more recently than the GeForce GTX 1080, 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 GeForce GTX 1080 when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GeForce GTX 1080 has 4096 MB more video memory than the GTX 1650, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 1080 also has superior memory performance overall.

The GeForce GTX 1080 has 64 GB/sec greater memory bandwidth than the GTX 1650, which means that the memory performance of the GeForce GTX 1080 is much better than the GTX 1650.

The GeForce GTX 1650 Ultra has 896 Shader Processing Units and the GeForce GTX 1080 has 2560. However, the actual shader performance of the GTX 1650 is 1425 and the actual shader performance of the GeForce GTX 1080 is 5989. The GeForce GTX 1080 having 4564 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 1080 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 1650.

The GTX 1650 transistor size technology is 4 nm (nanometers) smaller than the GeForce GTX 1080. This means that the GTX 1650 is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GTX 1080.

The GeForce GTX 1650 Ultra requires 90 Watts to run and the GeForce GTX 1080 requires 180 Watts. We would recommend a PSU with at least 400 Watts for the GTX 1650 and a PSU with at least 500 Watts for the GeForce GTX 1080. The GeForce GTX 1080 requires 90 Watts more than the GTX 1650 to run. The difference is significant enough that the GeForce GTX 1080 may have an adverse affect on your yearly electricity bills in comparison to the GTX 1650.
