Compare any two graphics cards:
GeForce GTX 880M vs Radeon R9 M380
IntroThe GeForce GTX 880M features a GPU core clock speed of 954 MHz, and the 4096 MB of GDDR5 memory is set to run at 1000 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon R9 M380, which has a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GTX 880M should theoretically be much superior to the Radeon R9 M380 overall. (explain)
Texel RateThe GeForce GTX 880M will be quite a bit (more or less 205%) faster with regards to AF than the Radeon R9 M380. (explain)
Pixel RateThe GeForce GTX 880M will be a lot (approximately 91%) faster with regards to full screen anti-aliasing than the Radeon R9 M380, and will be able to handle higher resolutions without slowing down too much. (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 information (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated 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 graphics 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 maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
