GeForce 8800 GS vs GeForce GTX 950M

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce 8800 GS		105 Watts
	Difference: 50 Watts (91%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GS should be 20% faster than the GeForce GTX 950M in general, due to its higher data rate. (explain)

GeForce 8800 GS		38400 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The GeForce GTX 950M is much (about 38%) more effective at AF than the GeForce 8800 GS. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 10160 (38%)

Pixel Rate

The GeForce GTX 950M should be a lot (more or less 122%) faster with regards to full screen anti-aliasing than the GeForce 8800 GS, and will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 8024 (122%)

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 max amount of data (measured in MB per second) that can be transported past the external memory interface in one 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 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
