Compare any two graphics cards:
Radeon HD 5870 vs Radeon R9 380X
IntroThe Radeon HD 5870 uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a frequency of 1200 MHz on this particular model. It features 1600(320x5) SPUs as well as 80 Texture Address Units and 32 ROPs.Compare those specs to the Radeon R9 380X, which makes use of a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 memory works at a speed of 1425 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 380X, in theory, should be just a bit faster than the Radeon HD 5870 overall. (explain)
Texel RateThe Radeon R9 380X will be a lot (more or less 83%) more effective at texture filtering than the Radeon HD 5870. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 380X is superior to the Radeon HD 5870, not by a very large margin though. (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 information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 applied in one second. This number is calculated by multiplying the total number 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 applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 get to the max fill rate.
