The link: X470 vs. X370 motherboards
When we look at the new AMD X470 motherboards, the differences with their X370 based predecessors are not very big. However, there are a number of trends that have been embraced by almost the entire market.
Whereas the RGB hype has been going on for years, last year a new connector was added. The 3-pin addressable RGB header can be found on almost all of the more expensive X470 motherboards, whereas in the previous generation it was still unique. It differs per manufacturer what this connection is called - addressable, digital or rainbow RGB - but it does the same in all cases: you can control the LEDs of a suitable strip individually.
On nine of the fourteen boards we also find an M.2-heatsink, which you can stick on an NVMe SSD so that it loses its heat more easily. In our X370 roundup, that feature was still limited to two high-end models. By the way, at the end of last year we searched for the best M.2 heatsink, but you can be sure that such a heatsink always brings about an improvement of the cooling.
What's more, we see that many manufacturers are a little bit more loose with the memory speeds you can set. Although Ryzen remains more selective in terms of memory than Intel's socket 1151 platform, there is a tendency for second-generation CPUs to be able to operate at somewhat higher speeds - manufacturers therefore make it possible to set these speeds. With ASRock you can set the memory to at most DDR4-4000, with the other brands DDR4-4200 is possible, although there is little chance that you will get close to such speeds without serious overclocking.
Every manufacturer has now also built-in support for loading XMP profiles for your memory. That's actually an Intel technology for automatically setting the correct speeds and timings, but you can also do that on all X470 boards with the touch of a button.
