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

Intro

The GeForce 8800 GTS (G80) 320MB comes with core clock speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 RAM. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.

Compare all of that to the GeForce GTX 950M, which has a GPU core clock speed of 914 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 950M 32000 MB/sec
Difference: 31360 (98%)

Texel Rate

The GeForce GTX 950M will be a lot (more or less 48%) better at anisotropic 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

The GeForce GTX 950M is quite a bit (about 43%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and should be able to handle higher screen resolutions more effectively. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
