GeForce 8800 Ultra vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which features core speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

GeForce GTX 950M		55 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 116 Watts (211%)

Memory Bandwidth

Theoretically, the GeForce 8800 Ultra should be quite a bit faster than the GeForce GTX 950M in general. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 71680 (224%)

Texel Rate

The GeForce 8800 Ultra is a small bit (more or less 7%) faster with regards to texture filtering than the GeForce GTX 950M. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 2608 (7%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 8800 Ultra is the winner, but only just. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 64 (0%)

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 data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
