Compare any two graphics cards:
Radeon HD 5850 vs Radeon R9 380 4G
IntroThe Radeon HD 5850 features a clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is made up of 1440(288x5) SPUs, 72 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon R9 380 4G, which has a core clock speed of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 380 4G should be 43% quicker than the Radeon HD 5850 in general, due to its higher data rate. (explain)
Texel RateThe Radeon R9 380 4G should be quite a bit (approximately 108%) more effective at AF than the Radeon HD 5850. (explain)
Pixel RateThe Radeon R9 380 4G should be quite a bit (approximately 34%) more effective at AA than the Radeon HD 5850, and also will be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, 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, 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 figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
