GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which has core speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 57600 (257%)

Texel Rate

The GeForce GTX 750 is a lot (about 278%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 24000 (278%)

Pixel Rate

The GeForce GTX 750 is much (approximately 278%) more effective at full screen anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		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 (measured in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
