Compare any two graphics cards:
GeForce 920M vs Radeon R9 280X
IntroThe GeForce 920M features clock speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 32 TAUs and 8 ROPs.Compare that to the Radeon R9 280X, which makes use of a 28 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 280X should be 1900% faster than the GeForce 920M in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 280X is much (more or less 256%) better at anisotropic filtering than the GeForce 920M. (explain)
Pixel RateThe Radeon R9 280X will be much (about 256%) more effective at anti-aliasing than the GeForce 920M, and should be capable of handling higher resolutions while still performing well. (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 (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
