Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon HD 3650 256MB
IntroThe GeForce 8600 GT 256MB GDDR3 comes with a GPU clock speed of 540 MHz, and the 256 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the Radeon HD 3650 256MB, which has a clock speed of 725 MHz and a DDR2 memory frequency of 800 MHz. It also features a 128-bit bus, and uses a 55 nm design. It is made up of 120(24x5) SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3650 256MB will be 14% quicker than the GeForce 8600 GT 256MB GDDR3 overall, due to its greater data rate. (explain)
Texel RateThe GeForce 8600 GT 256MB GDDR3 is a lot (more or less 49%) more effective at AF than the Radeon HD 3650 256MB. (explain)
Pixel RateThe GeForce 8600 GT 256MB GDDR3 is quite a bit (about 49%) more effective at FSAA than the Radeon HD 3650 256MB, and able to handle higher resolutions without slowing down too much. (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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
