Compare any two graphics cards:
GeForce GTX 590 vs Radeon R9 M290X
IntroThe GeForce GTX 590 has clock speeds of 607 MHz on the GPU, and 855 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs as well as 64 TAUs and 48 ROPs.Compare that to the Radeon R9 M290X, which comes with a core clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 590 should be 114% quicker than the Radeon R9 M290X in general, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 590 will be just a bit (about 14%) faster with regards to texture filtering than the Radeon R9 M290X. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 590 is superior to the Radeon R9 M290X, by a large margin. (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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
