Compare any two graphics cards:
GeForce GTX 580 vs Radeon R9 380 4G
IntroThe GeForce GTX 580 features a clock frequency of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.Compare all of that to the Radeon R9 380 4G, which has a clock frequency of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 580 should in theory be a bit superior to the Radeon R9 380 4G in general. (explain)
Texel RateThe Radeon R9 380 4G should be quite a bit (approximately 120%) faster with regards to texture filtering than the GeForce GTX 580. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 580 is the winner, though not 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 applied in one second. This is calculated by multiplying the total amount of texture units by the core 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 applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
