Compare any two graphics cards:
GeForce 920M vs Radeon HD 6770
IntroThe GeForce 920M features a core clock frequency of 954 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the Radeon HD 6770, which features GPU clock speed of 900 MHz, and 512 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is comprised of 800 SPUs, 40 Texture Address Units, and 16 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 6770 should in theory be a lot faster than the GeForce 920M overall. (explain)
Texel RateThe Radeon HD 6770 should be just a bit (about 18%) faster with regards to anisotropic filtering than the GeForce 920M. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6770 is the winner, 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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
