Compare any two graphics cards:
GeForce 825M vs Radeon HD 4550 512MB
IntroThe GeForce 825M has a GPU core speed of 850 MHz, and the 2048 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all of that to the Radeon HD 4550 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 600 MHz. The GDDR3 memory works at a speed of 800 MHz on this particular model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 825M should be a bit faster than the Radeon HD 4550 512MB in general. (explain)
Texel RateThe GeForce 825M is quite a bit (about 183%) more effective at texture filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateThe GeForce 825M is much (about 183%) better at AA than the Radeon HD 4550 512MB, and also will be capable of handling higher screen resolutions more effectively. (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 data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
