Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 4550 256MB
IntroThe GeForce GT 440 3GB makes use of a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 memory runs at a speed of 900 MHz on this particular model. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 4550 256MB, which features clock speeds of 600 MHz on the GPU, and 800 MHz on the 256 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 440 3GB should be 238% faster than the Radeon HD 4550 256MB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GT 440 3GB should be a lot (more or less 197%) faster with regards to AF than the Radeon HD 4550 256MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 440 3GB is a better choice, by far. (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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
