Compare any two graphics cards:
GeForce GTX 880M vs Radeon HD 3850 256MB
IntroThe GeForce GTX 880M comes with a GPU core speed of 954 MHz, and the 4096 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 TAUs, and 32 ROPs.Compare all of that to the Radeon HD 3850 256MB, which comes with GPU core speed of 668 MHz, and 256 MB of GDDR3 memory set to run at 828 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 880M should in theory be much faster than the Radeon HD 3850 256MB overall. (explain)
Texel RateThe GeForce GTX 880M should be a lot (more or less 1043%) better at AF than the Radeon HD 3850 256MB. (explain)
Pixel RateThe GeForce GTX 880M is a lot (more or less 186%) faster with regards to anti-aliasing than the Radeon HD 3850 256MB, and should be capable of handling higher screen 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once 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 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 clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
