Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 5570
IntroThe GeForce GT 440 3GB features a core clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.Compare all of that to the Radeon HD 5570, which has clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 3GB is 50% faster than the Radeon HD 5570 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GT 440 3GB should be a small bit (more or less 10%) faster with regards to texture filtering than the Radeon HD 5570. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 440 3GB is a better choice, by a large margin. (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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
