GeForce 8800 GTS (G92) vs GeForce GTX 880M

Intro

Compare those specs to the GeForce GTX 880M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 954 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Texel Rate

The GeForce GTX 880M should be quite a bit (more or less 194%) more effective at texture filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 80512 (194%)

Pixel Rate

The GeForce GTX 880M should be much (approximately 194%) more effective at anti-aliasing than the GeForce 8800 GTS (G92), and will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce 8800 GTS (G92)		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 largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 get to the maximum fill rate.
