Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 3850 512MB
IntroThe GeForce GT 240 GDDR5 1GB features a GPU clock speed of 550 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon HD 3850 512MB, which comes with a core clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It features 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 240 GDDR5 1GB, in theory, should perform a bit faster than the Radeon HD 3850 512MB in general. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB will be a lot (approximately 65%) faster with regards to anisotropic filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 3850 512MB is a better choice, and very much so. (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 data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
