Compare any two graphics cards:
Radeon HD 7970 vs Radeon R9 380 4G
IntroThe Radeon HD 7970 makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.Compare all of that to the Radeon R9 380 4G, which comes with GPU clock speed of 970 MHz, and 4096 MB of GDDR5 memory set to run at 1425 MHz through a 256-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7970, in theory, should perform quite a bit faster than the Radeon R9 380 4G in general. (explain)
Texel RateThe Radeon HD 7970 will be a bit (about 9%) more effective at anisotropic filtering than the Radeon R9 380 4G. (explain)
Pixel RateThe Radeon R9 380 4G is a small bit (about 5%) more effective at FSAA than the Radeon HD 7970, and should be capable of handling higher 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 max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
