GeForce 8600 GT 1GB DDR2 vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which features core clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

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

As far as performance goes, the GeForce GTX 750 should in theory be quite a bit superior to the GeForce 8600 GT 1GB DDR2 overall. (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 a lot (approximately 278%) more effective at texture filtering 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 750 is superior to the GeForce 8600 GT 1GB DDR2, by a large margin. (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 data (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
