A 20c reduction yes I got that but that is just temperature. He is doing an all core overclock at a fixed voltage and from what I understand he is primarily testing temperature reduction NOT under normal conditions (ie: letting the CPU decide what to do) because he ultimately want to produce and sell delidding products. (nothing wrong with that btw)Not easy to speak with AMD supporters that ignore what Black's Equation means...
Are you serious ?
It is on the web since 26 Sept...
20° just by delidding it.
It is an insane result, showing us how bad designed this IHS is.
So he got a 50MHz gain. Then after increasing voltage to 5.5GHz all core so maybe in total 100Mhz gain? It's not that clear to me from the video there was a tangible performance benefit per risk/cost to delidding so I would prefer to have a good analysis from a more controlled experiment before and after deledding. This limited data doesn't really answer if the IHS is really a problem let alone if delidding is really the beneficial answer. (I degress that there is something I may have missed in the video so feel free to correct me if I missed something)
Interestingly he notes the the CPU package power reduces with reduced temperature (still under 200W) so strictly speaking what I have read so far the CPU will drive to 95c. However I take it why that is not happening here is is because he is manually setting clocks and voltage in this case, thusly NOT raising the power limits which the CPU will typically control given the parameter limits in PBO.
If he was letting the CPU be in control and raised his PBO limits would the CPU still continue to drive to 95c when delidded? Would that still produce real gains over 200W?
I suspect not but I have a burning desire for someone to prove to me what happens.
