Compare any two graphics cards:
GeForce GTX 580 vs Radeon RX 470
IntroThe GeForce GTX 580 uses a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 memory works at a speed of 1002 MHz on this particular card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.
Compare all of that to the Radeon RX 470, which has a clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon RX 470 will be 10% quicker than the GeForce GTX 580 overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon RX 470 is quite a bit (approximately 140%) faster with regards to anisotropic filtering than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 will be quite a bit (approximately 25%) faster with regards to full screen anti-aliasing than the Radeon RX 470, and also capable of handling higher screen resolutions more effectively. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
