Compare any two graphics cards:
Radeon HD 3650 256MB vs Radeon R9 M380
IntroThe Radeon HD 3650 256MB features a GPU clock speed of 725 MHz, and the 256 MB of DDR2 memory is set to run 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 those specs to the Radeon R9 M380, which comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M380 will be 275% faster than the Radeon HD 3650 256MB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 M380 is a lot (more or less 590%) more effective at AF than the Radeon HD 3650 256MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 M380 is superior to the Radeon HD 3650 256MB, 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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount 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 processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out 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 drawing the pixels (image) on the screen. The actual pixel fill 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 ability to get to the maximum fill rate.
