Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 5770
IntroThe GeForce GT 440 3GB features a clock frequency of 594 MHz and a GDDR3 memory frequency 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 5770, which has a clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5770 should in theory perform much faster than the GeForce GT 440 3GB overall. (explain)
Texel RateThe Radeon HD 5770 is a lot (more or less 138%) faster with regards to AF than the GeForce GT 440 3GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 440 3GB is a better choice, though not 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 max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
