Compare any two graphics cards:
Radeon HD 5970 vs Radeon R9 380 4G
IntroThe Radeon HD 5970 features a clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It features 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.Compare those specifications to the Radeon R9 380 4G, which uses a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 memory works at a frequency of 1425 MHz on this particular card. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 5970 should in theory be a lot superior to the Radeon R9 380 4G overall. (explain)
Texel RateThe Radeon HD 5970 should be quite a bit (about 114%) faster with regards to anisotropic filtering than the Radeon R9 380 4G. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 5970 is a better choice, by far. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: 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 bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
