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 RAM is set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 TAUs, and 24 ROPs.Compare those specifications to the Radeon HD 3650 512MB, which has GPU core speed of 725 MHz, and 512 MB of GDDR3 RAM set to run at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 440 1.5GB should perform a lot faster than the Radeon HD 3650 512MB in general. (explain)
Texel RateThe GeForce GT 440 1.5GB is quite a bit (approximately 146%) better at AF than the Radeon HD 3650 512MB. (explain)
Pixel RateThe GeForce GT 440 1.5GB will be quite a bit (about 392%) more effective at anti-aliasing than the Radeon HD 3650 512MB, and capable of handling higher resolutions more effectively. (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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
