In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro NVS 450 are massively better than the Nvidia GeForce 6150 LE.

The Quadro NVS 450 was released over three years more recently than the GeForce 6150 LE, and so the Quadro NVS 450 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6150 LE 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 Quadro NVS 450 has 512 MB video memory, but the GeForce 6150 LE does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 6150 LE has 2 Shader Processing Units and the Quadro NVS 450 has 16. However, the actual shader performance of the GeForce 6150 LE is 1 and the actual shader performance of the Quadro NVS 450 is 9. The Quadro NVS 450 having 8 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro NVS 450 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6150 LE.

The Quadro NVS 450 requires 35 Watts to run but there is no entry for the GeForce 6150 LE. We would recommend a PSU with at least 300 Watts for the Quadro NVS 450, but we do not have a recommended PSU wattage for the GeForce 6150 LE.
