Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 3650 512MB
IntroThe GeForce GT 320 has a GPU core speed of 540 MHz, and the 1024 MB of GDDR3 memory is set to run at 790 MHz through a 128-bit bus. It also is made up of 72 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon HD 3650 512MB, which comes with core speeds of 725 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 120(24x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3650 512MB should perform a small bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GT 320 should be a lot (about 123%) better at AF than the Radeon HD 3650 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 320 is superior to the Radeon HD 3650 512MB, by a large margin. (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 transported across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
