GeForce 8800 GT 512MB vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which features a core clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 2960 (9%)

Pixel Rate

The GeForce GTX 950M should be quite a bit (about 52%) more effective at FSAA than the GeForce 8800 GT 512MB, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 5024 (52%)

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 largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
