GeForce 8800 Ultra vs GeForce GTX 880M

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M		130 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 41 Watts (32%)

Memory Bandwidth

In theory, the GeForce GTX 880M should be quite a bit faster than the GeForce 8800 Ultra overall. (explain)

GeForce GTX 880M		128000 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 24320 (23%)

Texel Rate

The GeForce GTX 880M should be a lot (about 212%) more effective at texture filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 82944 (212%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 880M is superior to the GeForce 8800 Ultra, by a large margin. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 15840 (108%)

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 (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
