Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 3650 512MB
IntroThe GeForce GT 440 1.5GB features a GPU core speed of 594 MHz, and the 1536 MB of GDDR3 memory is set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.Compare those specifications to the Radeon HD 3650 512MB, which comes with a GPU core clock speed of 725 MHz, and 512 MB of GDDR3 RAM set to run at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 1.5GB should perform quite a bit faster than the Radeon HD 3650 512MB overall. (explain)
Texel RateThe GeForce GT 440 1.5GB should be a lot (more or less 146%) better at AF than the Radeon HD 3650 512MB. (explain)
Pixel RateThe GeForce GT 440 1.5GB will be much (more or less 392%) more effective at anti-aliasing than the Radeon HD 3650 512MB, and should be able to handle higher 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

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling 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 the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
