Compare any two graphics cards:
GeForce GTX 590 vs Radeon R9 390X 8G
IntroThe GeForce GTX 590 makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM runs at a frequency of 855 MHz on this specific card. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.Compare those specs to the Radeon R9 390X 8G, which comes with a core clock frequency of 1050 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 512-bit memory bus, and makes use of a 28 nm design. It features 2816 SPUs, 176 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390X 8G should be 17% faster than the GeForce GTX 590 overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 390X 8G is quite a bit (about 138%) better at AF than the GeForce GTX 590. (explain)
Pixel RateThe Radeon R9 390X 8G will be a little bit (more or less 15%) better at anti-aliasing than the GeForce GTX 590, and will be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
