Compare any two graphics cards:
GeForce 9500 GT DDR2 vs Radeon HD 4550 256MB
IntroThe GeForce 9500 GT DDR2 comes with a GPU core speed of 550 MHz, and the 256 MB of DDR2 memory runs at 500 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon HD 4550 256MB, which comes with a core clock speed of 600 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9500 GT DDR2, in theory, should be a lot faster than the Radeon HD 4550 256MB in general. (explain)
Texel RateThe GeForce 9500 GT DDR2 should be quite a bit (about 83%) more effective at AF than the Radeon HD 4550 256MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 9500 GT DDR2 is the winner, and very much so. (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 data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
