GeForce 8800 GTS (G80) 320MB vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which has GPU core speed of 914 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce 8800 GTS (G80) 320MB		143 Watts
	Difference: 88 Watts (160%)

Memory Bandwidth

Theoretically, the GeForce 8800 GTS (G80) 320MB should be quite a bit faster than the GeForce GTX 950M in general. (explain)

GeForce 8800 GTS (G80) 320MB		63360 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 31360 (98%)

Texel Rate

The GeForce GTX 950M will be much (more or less 48%) more effective at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 11936 (48%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950M is a better choice, by a large margin. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 4364 (43%)

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 data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
