Hi there
I suppose, that is because the ryzen APU is monitoring all the time the TDP, if it goes too high you will blow the capacitors depending on the chip, in this case the main apu capacitors. By reducing the CPU portion (when possible), you are cheating the APU TDP monitor, giving you more tolerance for a higher gpu frequency, it can be a nice boost given it would be better sustained and not throttled back when heat is an issue; and with no apparent damage to the capacitors life. Obviously this will help you in some games but not in others that do not depend on frequency(for example a game that depends on shader units count and not clock, or one game that depends more on cpu and not gpu).
I have question, if you scaled down the cpu clock to 60%, how much % up did you achieved with the GPU, a 40%? If not mistaken with 1300mhz, a 40% clock increase will be 1820mhz... I suppose you didn't end that high but if that was the case, the capacitors would have endure but vram will prematurely die if not well ventilated. Bad Vram is a pain in the ass, it can show up anytime without advise, and is not immediately evident to diagnose. Lots of used cards are like this on ebay, they randomly crash without, can be playing a game or using Word.
Something very similar to what AMD/Nvidia/Intel do, but in reverse whenever a chip design or manufacturing process is flawed, they deactivate some internals, tweak the clocks and sell them as a lower tier product.
