Compare any two graphics cards:
GeForce GTX 980 vs Radeon RX 580
IntroThe GeForce GTX 980 has a clock frequency of 1126 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.
Compare those specifications to the Radeon RX 580, which uses a 14 nm design. AMD has clocked the core frequency at 1257 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Performance-wise, the Radeon RX 580 should theoretically be a small bit superior to the GeForce GTX 980 overall. (explain)
Texel RateThe Radeon RX 580 is much (approximately 26%) better at anisotropic filtering than the GeForce GTX 980. (explain)
Pixel RateThe GeForce GTX 980 is a lot (more or less 79%) faster with regards to FSAA than the Radeon RX 580, and able to handle higher screen resolutions while still performing well. (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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
