Compare any two graphics cards:
Radeon R9 280 vs Radeon RX 570
IntroThe Radeon R9 280 features a GPU clock speed of 933 MHz, and the 3072 MB of GDDR5 RAM runs at 1250 MHz through a 384-bit bus. It also features 1792 Stream Processors, 112 Texture Address Units, and 32 Raster Operation Units.
Compare all of that to the Radeon RX 570, which makes use of a 14 nm design. AMD has clocked the core speed at 1168 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon R9 280, in theory, should perform a bit faster than the Radeon RX 570 overall. (explain)
Texel RateThe Radeon RX 570 will be quite a bit (more or less 43%) faster with regards to anisotropic filtering than the Radeon R9 280. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 570 is a better choice, 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
