Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon R9 M385X
IntroThe Radeon HD 3650 512MB uses a 55 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR3 memory works at a speed of 800 MHz on this specific card. It features 120(24x5) SPUs along with 8 TAUs and 4 ROPs.Compare that to the Radeon R9 M385X, which has a clock frequency of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M385X should be 275% quicker than the Radeon HD 3650 512MB overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 M385X should be much (more or less 962%) more effective at anisotropic filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 M385X is the winner, and very much so. (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 transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
