GeForce 8600 GT 512MB DDR2 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this card. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 63 Watts (134%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti should be 575% quicker than the GeForce 8600 GT 512MB DDR2 in general, due to its higher bandwidth. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 73600 (575%)

Texel Rate

The GeForce GTX 650 Ti will be quite a bit (about 587%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 50752 (587%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is superior to the GeForce 8600 GT 512MB DDR2, and very much so. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 10528 (244%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
