Compare any two graphics cards:
GeForce 825M vs Radeon HD 5450
IntroThe GeForce 825M comes with core clock speeds of 850 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare all of that to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 RAM runs at a speed of 800 MHz on this specific model. It features 80(16x5) SPUs along with 8 Texture Address Units 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 should be quite a bit (more or less 162%) faster with regards to anisotropic filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce 825M should be quite a bit (more or less 162%) faster with regards to AA than the Radeon HD 5450, and also able to handle higher screen resolutions while still performing well. (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 maximum amount of data (in units of MB per second) that can be moved 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 RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high 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 higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
