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 RAM is set to run at 792 MHz through a 320-bit bus. It also is comprised of 96 Stream Processors, 48 TAUs, and 20 Raster Operation Units.

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

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

Texel Rate

The GeForce GTX 950M should be a lot (about 48%) faster with regards to 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

If running with a high screen resolution is important to you, then the GeForce GTX 950M is superior to the GeForce 8800 GTS (G80) 320MB, and very much so. (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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If 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 processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
