News Intel Core i9-10900K Listed With 5.1 GHz Boost Clock

Yea, boost clock on this chip is really an irrelevant number. Once you load up those cores, this thing will throttle like crazy from all the heat.

It will be interesting to see this thing go up against my 3900x.

What heat are you talking about?
The only use case where heat will be a problem is in full AVX load and whoever uses that already knows not to use the highest clocks possible.
In any other workload power usage is extremely low and on the same general level as ryzen 3xxx series.
