Compare any two graphics cards:
GeForce 930M vs Radeon HD 5550
IntroThe GeForce 930M features a core clock speed of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 5550, which uses a 40 nm design. AMD has clocked the core frequency at 550 MHz. The DDR2 memory runs at a frequency of 400 MHz on this particular model. It features 320(64x5) SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 930M, in theory, should perform a small bit faster than the Radeon HD 5550 overall. (explain)
Texel RateThe GeForce 930M is quite a bit (about 153%) faster with regards to anisotropic filtering than the Radeon HD 5550. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 930M is a better choice, and very much so. (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 megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
