GeForce 9800 GT 1GB vs GeForce GTX 880M

Intro

Compare all of that to the GeForce GTX 880M, which comes with core clock speeds of 954 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

GeForce 9800 GT 1GB		105 Watts
GeForce GTX 880M		130 Watts
	Difference: 25 Watts (24%)

Memory Bandwidth

In theory, the GeForce GTX 880M should be 122% faster than the GeForce 9800 GT 1GB in general, because of its greater data rate. (explain)

GeForce GTX 880M		128000 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 70400 (122%)

Texel Rate

The GeForce GTX 880M should be a lot (approximately 263%) faster with regards to AF 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 using a high screen resolution is important to you, then the GeForce GTX 880M is a better choice, 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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
