Compare any two graphics cards:
GeForce 830M vs Radeon R7 M265
IntroThe GeForce 830M comes with a GPU clock speed of 1029 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is comprised of 256 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the Radeon R7 M265, which features a clock speed of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon R7 M265 should perform a lot faster than the GeForce 830M overall. (explain)
Texel RateThe Radeon R7 M265 is a little bit (more or less 6%) faster with regards to AF than the GeForce 830M. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 830M is a better choice, by far. (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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 by the core 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
