Compare any two graphics cards:
Radeon HD 4730 vs Radeon R9 M380
IntroThe Radeon HD 4730 features a GPU clock speed of 700 MHz, and the 512 MB of GDDR5 memory is set to run at 900 MHz through a 128-bit bus. It also features 640(128x5) Stream Processors, 32 TAUs, and 8 ROPs.Compare that to the Radeon R9 M380, which features a clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M380 should be quite a bit faster than the Radeon HD 4730 in general. (explain)
Texel RateThe Radeon R9 M380 will be much (more or less 79%) better at anisotropic filtering than the Radeon HD 4730. (explain)
Pixel RateThe Radeon R9 M380 is much (about 186%) better at full screen anti-aliasing than the Radeon HD 4730, and also will be capable of handling higher resolutions more effectively. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
