Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M		33 Watts
GeForce 9600 GSO ASUS 512		84 Watts
	Difference: 51 Watts (155%)

Memory Bandwidth

Theoretically, the GeForce 9600 GSO ASUS 512 should be a little bit faster than the GeForce 825M in general. (explain)

GeForce 9600 GSO ASUS 512		16000 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 9600 GSO ASUS 512 will be a lot (more or less 94%) more effective at AF than the GeForce 825M. (explain)

GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 12800 (94%)

Pixel Rate

The GeForce 825M is just a bit (about 3%) better at FSAA than the GeForce 9600 GSO ASUS 512, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 825M		6800 Mpixels/sec
GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
	Difference: 200 (3%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
