GeForce 8600 GT 512MB DDR2 vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which uses a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
GeForce GTX 750		55 Watts
	Difference: 8 Watts (17%)

Memory Bandwidth

In theory, the GeForce GTX 750 is 525% faster than the GeForce 8600 GT 512MB DDR2 in general, due to its greater bandwidth. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 67200 (525%)

Texel Rate

The GeForce GTX 750 is much (approximately 278%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 24000 (278%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 750 is a better choice, by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8600 GT 512MB 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 max amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
