Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon R7 M265
IntroThe Radeon HD 3650 512MB has a GPU clock speed of 725 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare all that to the Radeon R7 M265, which comes with a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 M265, in theory, should be much faster than the Radeon HD 3650 512MB in general. (explain)
Texel RateThe Radeon R7 M265 should be much (more or less 200%) better at texture filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R7 M265 is the winner, 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: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
