GeForce 920M 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 memory set to run at 900 MHz through a 256-bit bus. It also features 64 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9600 GT 512MB, in theory, should be quite a bit faster than the GeForce 920M in general. (explain)

GeForce 9600 GT 512MB		57600 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 920M is quite a bit (more or less 47%) faster with regards to AF than the GeForce 9600 GT 512MB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 9728 (47%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 9600 GT 512MB is superior to the GeForce 920M, by a large margin. (explain)

GeForce 9600 GT 512MB		10400 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 2768 (36%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's 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 better the card's 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 can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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