Overclocking on Ryzen is a waste of time anyhow. You are better off simply running at the default precision boost profile or if you have good enough cooling, using PBO/PBO2. Precision boost overdrive in almost all cases seems to offer better gains than what you'll see from manually overclocking or using any kind of automatic utility.
I think the tool is mainly aimed at laptops with severely locked down power limits.
Its been available awhile but needed manual interaction with no easy frontend interface.
I have a 3500u laptop with a crippled 12w power limit, manually getting it upto 25w increases performance dramatically.
I have a £350 laptop that can actually game even though that's not what I bought it for.
Obviously theres room for abuse and I await the 'I killed my laptop' posts when people overdo it on laptops with poor thermal design.
Mine though tops out at 72c max when under full cpu/gpu stress so it's entirely capable of managing much more than the stock 12w power limit imposed from the factory (lenovo v155).
Its an incredibly useful tool for a ryzen laptop owner that has some semblance of common sense.
