Compare any two graphics cards:
GeForce 920M vs Radeon HD 5550
IntroThe GeForce 920M features a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare all that to the Radeon HD 5550, which comes with a clock speed of 550 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 920M should theoretically perform just a bit faster than the Radeon HD 5550 in general. (explain)
Texel RateThe GeForce 920M is much (approximately 247%) better at AF than the Radeon HD 5550. (explain)
Pixel RateThe GeForce 920M should be much (approximately 73%) better at full screen anti-aliasing than the Radeon HD 5550, and capable of handling higher resolutions better. (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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number 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 the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends 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.
