Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 4550 512MB
IntroThe GeForce GT 440 1.5GB uses a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 4550 512MB, which has core clock speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 1.5GB should be 238% quicker than the Radeon HD 4550 512MB in general, because of its greater data rate. (explain)
Texel RateThe GeForce GT 440 1.5GB will be quite a bit (more or less 197%) better at anisotropic filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 440 1.5GB 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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
