Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 460
IntroThe GeForce 8600 GT 512MB DDR2 comes with a clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit bus, and makes use of a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.
Compare those specs to the GeForce GTX 460, which comes with a clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 192-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 460 should theoretically be a lot better than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 460 is much (about 338%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 460 is superior to the GeForce 8600 GT 512MB DDR2, 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
