Compare any two graphics cards:
GeForce 810M vs Radeon HD 4550 256MB
IntroThe GeForce 810M has a GPU clock speed of 738 MHz, and the 1024 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also features 48 SPUs, 8 TAUs, and 4 Raster Operation Units.Compare all that to the Radeon HD 4550 256MB, which makes use of a 55 nm design. AMD has clocked the core speed at 600 MHz. The DDR3 memory runs at a speed of 800 MHz on this specific model. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 810M should be a small bit faster than the Radeon HD 4550 256MB overall. (explain)
Texel RateThe GeForce 810M will be much (about 23%) better at AF than the Radeon HD 4550 256MB. (explain)
Pixel RateThe GeForce 810M is a lot (more or less 23%) better at anti-aliasing than the Radeon HD 4550 256MB, 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: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
