Compare any two graphics cards:
GeForce 825M vs Radeon HD 5450
IntroThe GeForce 825M features core speeds of 850 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare that to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this particular model. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 825M, in theory, should perform just a bit faster than the Radeon HD 5450 in general. (explain)
Texel RateThe GeForce 825M will be a lot (about 162%) more effective at anisotropic filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce 825M is a lot (more or less 162%) better at AA than the Radeon HD 5450, and also able to handle higher resolutions better. (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 MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
