Compare any two graphics cards:
GeForce GTX 880M vs Radeon HD 7850
IntroThe GeForce GTX 880M has a GPU core clock speed of 954 MHz, and the 4096 MB of GDDR5 RAM runs at 1000 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the Radeon HD 7850, which comes with GPU clock speed of 860 MHz, and 2048 MB of GDDR5 memory set to run at 1200 MHz through a 256-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthTheoretically speaking, the Radeon HD 7850 should be a bit faster than the GeForce GTX 880M in general. (explain)
Texel RateThe GeForce GTX 880M is much (about 122%) faster with regards to AF than the Radeon HD 7850. (explain)
Pixel RateThe GeForce GTX 880M should be a small bit (about 11%) better at anti-aliasing than the Radeon HD 7850, and also will be able to handle 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 within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 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 AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
