GeForce 9600 GT 512MB vs GeForce GTX 880M

Intro

Compare all of that to the GeForce GTX 880M, which comes with a clock frequency of 954 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

	Difference: 70400 (122%)

Texel Rate

The GeForce GTX 880M will be a lot (more or less 487%) more effective at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 101312 (487%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 880M is a better choice, by a large margin. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 20128 (194%)

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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
