Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 5570
IntroThe GeForce GT 440 1.5GB features a GPU core speed of 594 MHz, and the 1536 MB of GDDR3 RAM is set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 Texture Address Units, and 24 Raster Operation Units.Compare all of that to the Radeon HD 5570, which features a core clock frequency of 650 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 400(80x5) SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 440 1.5GB should theoretically be much better than the Radeon HD 5570 in general. (explain)
Texel RateThe GeForce GT 440 1.5GB will be a small bit (approximately 10%) better at AF than the Radeon HD 5570. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GT 440 1.5GB 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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly record to the local memory in one 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
