Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 660
IntroThe GeForce 8600 GT 1GB GDDR3 has a GPU core clock speed of 540 MHz, and the 1024 MB of GDDR3 RAM runs at 700 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare that to the GeForce GTX 660, which has a clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 192-bit memory bus, and makes use of a 28 nm design. It is made up of 960 SPUs, 80 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 660 should be quite a bit faster than the GeForce 8600 GT 1GB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 660 should be quite a bit (approximately 807%) faster with regards to texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 660 is a better choice, by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
