Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8600 GT 512MB DDR2 comes with a GPU clock speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare that to the GeForce GT 240 GDDR5 1GB, which comes with GPU clock speed of 550 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 240 GDDR5 1GB should in theory be a lot superior to the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB will be a lot (approximately 104%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GT 240 GDDR5 1GB is a little bit (more or less 2%) better at anti-aliasing than the GeForce 8600 GT 512MB DDR2, and capable of handling higher resolutions while still performing well. (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 max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
