GeForce 9600 GSO 768MB vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which features clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce 9600 GSO 768MB		84 Watts
	Difference: 29 Watts (53%)

Memory Bandwidth

As far as performance goes, the GeForce 9600 GSO 768MB should in theory be a small bit superior to the GeForce GTX 950M in general. (explain)

GeForce 9600 GSO 768MB		38400 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The GeForce GTX 950M should be quite a bit (more or less 38%) better at texture filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 10160 (38%)

Pixel Rate

The GeForce GTX 950M is quite a bit (about 122%) more effective at anti-aliasing than the GeForce 9600 GSO 768MB, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 8024 (122%)

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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
