GeForce 8800 GT 1GB vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which comes with GPU core speed of 914 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 950M		32000 MB/sec
	Difference: 25600 (80%)

Texel Rate

The GeForce GTX 950M will be a small bit (more or less 9%) better at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 2960 (9%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, by a large margin. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 8800 GT 1GB		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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR 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 better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
