GeForce 8800 GS vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 914 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

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

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

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

Texel Rate

The GeForce GTX 950M will be much (more or less 38%) faster with regards to texture 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 lots of anti-aliasing 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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 can be applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
