GeForce 8600 GTS vs GeForce GTX 650 Ti

Intro

Compare those specifications to the GeForce GTX 650 Ti, which comes with clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 memory. It features 768 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GTS		75 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 35 Watts (47%)

Memory Bandwidth

The GeForce GTX 650 Ti should in theory be much faster than the GeForce 8600 GTS in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 8600 GTS		32000 MB/sec
	Difference: 54400 (170%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (more or less 450%) better at texture filtering than the GeForce 8600 GTS. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 8600 GTS		10800 Mtexels/sec
	Difference: 48592 (450%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 650 Ti is superior to the GeForce 8600 GTS, by a large margin. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 8600 GTS		5400 Mpixels/sec
	Difference: 9448 (175%)

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 maximum amount of data (in units of 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 its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
