GeForce 8600 GT 1GB DDR2 vs GeForce GTX 750

Intro

Compare that to the GeForce GTX 750, which has a GPU core clock speed of 1020 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2		47 Watts
GeForce GTX 750		55 Watts
	Difference: 8 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 should perform a lot faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 67200 (525%)

Texel Rate

The GeForce GTX 750 is quite a bit (more or less 278%) more effective at AF than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 24000 (278%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 is the winner, by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 12000 (278%)

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 megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
