GeForce 9800 GT 1GB vs GeForce GTX 880M

Intro

Compare all of that to the GeForce GTX 880M, which features GPU core speed of 954 MHz, and 4096 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 TAUs, and 32 ROPs.

GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 70400 (122%)

Texel Rate

The GeForce GTX 880M should be much (approximately 263%) more effective at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 88512 (263%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 880M is superior to the GeForce 9800 GT 1GB, and very much so. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 20928 (218%)

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 past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
