GeForce 8800 GTS (G92) vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 memory works at a frequency of 1000 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

GeForce GTX 950M		36560 Mtexels/sec
	Difference: 5040 (14%)

Pixel Rate

The GeForce GTX 950M should be a lot (approximately 41%) better at anti-aliasing than the GeForce 8800 GTS (G92), and able to handle higher screen resolutions better. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 4224 (41%)

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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
