GeForce 8800 GS vs GeForce GTX 950M

Intro

Compare that to the GeForce GTX 950M, which comes with a clock speed of 914 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce 8800 GS		105 Watts
	Difference: 50 Watts (91%)

Memory Bandwidth

In theory, the GeForce 8800 GS should perform just a bit faster than the GeForce GTX 950M overall. (explain)

GeForce 8800 GS		38400 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The GeForce GTX 950M will be a lot (approximately 38%) more effective at anisotropic filtering than the GeForce 8800 GS. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 10160 (38%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950M is the winner, and very much so. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 8024 (122%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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