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

Intro

The GeForce 8800 GTS (G80) 320MB has a GPU core clock speed of 513 MHz, and the 320 MB of GDDR3 memory is set to run at 792 MHz through a 320-bit bus. It also is made up of 96 Stream Processors, 48 TAUs, and 20 Raster Operation Units.

Compare those specs to the GeForce GTX 950M, which uses a 28 nm design. nVidia has clocked the core frequency at 914 MHz. The DDR3 memory works at a speed of 1000 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

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

Texel Rate

The GeForce GTX 950M will be a lot (more or less 48%) more effective 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 much (about 43%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and should be capable of handling higher resolutions better. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount 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 speed of the chip. The higher this number, the better the 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 amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
