GeForce 8600 GT 1GB DDR2 vs GeForce GTX 750

Intro

The GeForce 8600 GT 1GB DDR2 comes with a GPU core speed of 540 MHz, and the 1024 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the GeForce GTX 750, which uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular card. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

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

Memory Bandwidth

The GeForce GTX 750, in theory, should be much faster than 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 should be a lot (about 278%) faster with regards to 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 high levels of AA is important to you, then the GeForce GTX 750 is a better choice, and very much so. (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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied in one second. This 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
