Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 5570
IntroThe GeForce GT 440 3GB has a GPU clock speed of 594 MHz, and the 3072 MB of GDDR3 RAM runs at 900 MHz through a 192-bit bus. It also features 144 Stream Processors, 24 Texture Address Units, and 24 Raster Operation Units.Compare those specifications to the Radeon HD 5570, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 memory works at a frequency of 900 MHz on this particular card. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 440 3GB should be 50% quicker than the Radeon HD 5570 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GT 440 3GB should be a little bit (approximately 10%) more effective at texture filtering than the Radeon HD 5570. (explain)
Pixel RateThe GeForce GT 440 3GB should be a lot (approximately 174%) better at FSAA than the Radeon HD 5570, and also able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
