GeForce 940M vs GeForce 9600 GT 512MB

Intro

Compare all of that to the GeForce 9600 GT 512MB, which features GPU clock speed of 650 MHz, and 512 MB of GDDR3 RAM set to run at 900 MHz through a 256-bit bus. It also features 64 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9600 GT 512MB should in theory be quite a bit better than the GeForce 940M overall. (explain)

GeForce 9600 GT 512MB		57600 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The GeForce 940M will be quite a bit (more or less 24%) faster with regards to texture filtering than the GeForce 9600 GT 512MB. (explain)

GeForce 940M		25728 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 4928 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9600 GT 512MB is the winner, by far. (explain)

GeForce 9600 GT 512MB		10400 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 1824 (21%)

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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
