Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 6450 (OEM)
IntroThe GeForce GT 440 3GB has a clock frequency of 594 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 ROPs.Compare that to the Radeon HD 6450 (OEM), which comes with a core clock frequency of 625 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 64-bit bus, and makes use of a 40 nm design. It features 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 440 3GB should in theory be quite a bit superior to the Radeon HD 6450 (OEM) in general. (explain)
Texel RateThe GeForce GT 440 3GB is a lot (about 185%) better at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 440 3GB is the winner, 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 largest amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
