Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 3850 256MB
IntroThe GeForce GT 240 GDDR5 1GB comes with a GPU core 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 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 3850 256MB, which uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory is set to run at a speed of 828 MHz on this specific card. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator 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 256MB in general. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB is much (about 65%) faster with regards to texture filtering than the Radeon HD 3850 256MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 3850 256MB is superior to the GeForce GT 240 GDDR5 1GB, 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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
