GeForce 8600 GT 512MB DDR2 vs GeForce GTX 960

Intro

The GeForce 8600 GT 512MB DDR2 has core clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare those specs to the GeForce GTX 960, which comes with GPU core speed of 1127 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also features 1024 SPUs, 64 TAUs, and 32 ROPs.

Theoretically speaking, the GeForce GTX 960 is 775% faster than the GeForce 8600 GT 512MB DDR2 in general, due to its higher data rate. (explain)

GeForce GTX 960 112000 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 99200 (775%)

Texel Rate

The GeForce GTX 960 should be quite a bit (about 735%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GTX 960 72128 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 63488 (735%)

Pixel Rate

The GeForce GTX 960 is quite a bit (approximately 735%) more effective at full screen anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 960 36064 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 31744 (735%)

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 largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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