Compare any two graphics cards:
GeForce 930M vs Radeon HD 4550 512MB
IntroThe GeForce 930M has a clock speed of 928 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.Compare that to the Radeon HD 4550 512MB, which makes use of a 55 nm design. AMD has set the core speed at 600 MHz. The GDDR3 memory works at a speed of 800 MHz on this particular model. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce 930M should be a little bit faster than the Radeon HD 4550 512MB in general. (explain)
Texel RateThe GeForce 930M will be quite a bit (about 364%) more effective at texture filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 930M is superior to the Radeon HD 4550 512MB, by far. (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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
