Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 5450
IntroThe GeForce GT 220 GDDR3 comes with a GPU core speed of 625 MHz, and the 512 MB of GDDR3 memory runs at 1012 MHz through a 128-bit bus. It also is made up of 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 5450, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 memory runs at a frequency of 800 MHz on this specific model. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 220 GDDR3 should in theory be a lot superior to the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce GT 220 GDDR3 will be a lot (more or less 92%) more effective at texture filtering than the Radeon HD 5450. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 220 GDDR3 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 max amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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.
