Compare any two graphics cards:
GeForce 8500 GT vs GeForce GTX 460 1GB
IntroThe GeForce 8500 GT features a GPU core speed of 450 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is made up of 16 SPUs, 8 Texture Address Units, and 4 ROPs.Compare that to the GeForce GTX 460 1GB, which comes with a clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 460 1GB should perform quite a bit faster than the GeForce 8500 GT overall. (explain)
Texel RateThe GeForce GTX 460 1GB will be quite a bit (more or less 950%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce GTX 460 1GB is quite a bit (approximately 1100%) more effective at FSAA than the GeForce 8500 GT, and will be capable of handling higher screen resolutions better. (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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few 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.
