Compare any two graphics cards:
GeForce GTX 580 vs Radeon R9 M385X
IntroThe GeForce GTX 580 makes use of a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 RAM works at a speed of 1002 MHz on this particular card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.Compare those specs to the Radeon R9 M385X, which has core speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce GTX 580 should be quite a bit faster than the Radeon R9 M385X in general. (explain)
Texel RateThe Radeon R9 M385X will be a lot (approximately 25%) better at anisotropic filtering than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 will be much (about 111%) faster with regards to full screen anti-aliasing than the Radeon R9 M385X, and also able to handle higher screen resolutions without losing too much performance. (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 maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
