Compare any two graphics cards:
GeForce 930M vs Radeon HD 4550 512MB
IntroThe GeForce 930M features core clock speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.Compare those specifications to the Radeon HD 4550 512MB, which has a GPU core clock speed of 600 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 930M will be 13% faster than the Radeon HD 4550 512MB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce 930M is much (about 364%) better at AF than the Radeon HD 4550 512MB. (explain)
Pixel RateThe GeForce 930M is much (more or less 209%) faster with regards to anti-aliasing than the Radeon HD 4550 512MB, and also capable of handling higher screen resolutions without slowing down too much. (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 (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
