GeForce 8800 GTS (G92) vs GeForce GTX 880M

Intro

Compare those specs to the GeForce GTX 880M, which uses a 28 nm design. nVidia has set the core speed at 954 MHz. The GDDR5 RAM 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.

GeForce GTX 880M		130 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 5 Watts (4%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 880M should be 106% faster than the GeForce 8800 GTS (G92) overall, due to its higher bandwidth. (explain)

GeForce GTX 880M		128000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 65920 (106%)

Texel Rate

The GeForce GTX 880M will be a lot (about 194%) faster with regards to anisotropic 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

If using a high screen resolution is important to you, then the GeForce GTX 880M is the winner, by far. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
