Compare any two graphics cards:
GeForce 920M vs Radeon R5 M330
IntroThe GeForce 920M features a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 32 TAUs, and 8 ROPs.Compare that to the Radeon R5 M330, which comes with a core clock speed of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce 920M will be much (more or less 48%) more effective at texture filtering than the Radeon R5 M330. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R5 M330 is the winner, but only just. (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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
