GeForce 8600 GS (OEM) vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which comes with GPU 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 comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Texel Rate

The GeForce GTX 750 is much (more or less 278%) faster with regards to anisotropic filtering than the GeForce 8600 GS (OEM). (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 24000 (278%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is superior to the GeForce 8600 GS (OEM), by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8600 GS (OEM)		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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
