Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8600 GT 1GB GDDR3 comes with 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 GT 240 GDDR5 1GB, which has a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 240 GDDR5 1GB should theoretically be much better than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB is a lot (more or less 104%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GT 240 GDDR5 1GB is superior to the GeForce 8600 GT 1GB GDDR3, but it probably won't make a huge difference. (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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
