In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro NVS 290 are massively better than the Nvidia GeForce 6150 LE.

The Quadro NVS 290 has a 35 MHz higher core clock speed and 7 more Texture Mapping Units than the GeForce 6150 LE. This results in the Quadro NVS 290 providing 3.3 GTexel/s better texturing performance. Neither of these GPUs support DirectX 10 or higher, so Texture Rate holds more weight than when comparing more modern GPUs.

The Quadro NVS 290 has a 35 MHz higher core clock speed and 3 more Render Output Units than the GeForce 6150 LE. This results in the Quadro NVS 290 providing 1.4 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 Quadro NVS 290 was released over a year more recently than the GeForce 6150 LE, and so the Quadro NVS 290 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6150 LE.

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 290 has 256 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 290 has 16. However, the actual shader performance of the GeForce 6150 LE is 1 and the actual shader performance of the Quadro NVS 290 is 18. The Quadro NVS 290 having 17 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro NVS 290 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6150 LE.

The Quadro NVS 290 transistor size technology is 10 nm (nanometers) smaller than the GeForce 6150 LE. This means that the Quadro NVS 290 is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce 6150 LE. While they exhibit similar graphical performance, the Quadro NVS 290 should consume less power than the GeForce 6150 LE.

The Quadro NVS 290 requires 21 Watts to run but there is no entry for the GeForce 6150 LE.
