In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9300 GE are massively better than the Nvidia GeForce 6150 LE.

The GeForce 9300 GE has a 115 MHz higher core clock speed and 7 more Texture Mapping Units than the GeForce 6150 LE. This results in the GeForce 9300 GE providing 3.9 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 GeForce 9300 GE has a 115 MHz higher core clock speed and 3 more Render Output Units than the GeForce 6150 LE. This results in the GeForce 9300 GE providing 1.8 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 GeForce 9300 GE was released over three years more recently than the GeForce 6150 LE, and so the GeForce 9300 GE 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 GeForce 9300 GE 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 GeForce 9300 GE has 8. However, the actual shader performance of the GeForce 6150 LE is 1 and the actual shader performance of the GeForce 9300 GE is 4. The GeForce 9300 GE having 3 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 9300 GE delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6150 LE.

The GeForce 9300 GE transistor size technology is 25 nm (nanometers) smaller than the GeForce 6150 LE. This means that the GeForce 9300 GE is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 6150 LE. While they exhibit similar graphical performance, the GeForce 9300 GE should consume less power than the GeForce 6150 LE.

We would recommend a PSU with at least 300 Watts for the GeForce 9300 GE, but we do not have a recommended PSU wattage for the GeForce 6150 LE.
