Core i9-9900K 8-core Will have Soldered Heatspreader

You know that Intel eight-core Core i9-9900K that is coming. Word out on the street is that Intel has been shipping some samples to overclockers. And as they found out, the 8-core parts do not use thermal paste, however, have the heat spreader directly soldered towards the die, much like Ryzen has.

If you think about it, the reason behind this could be twofold.

1. Intel has been listening to the cries of all of us requesting a soldered SKUs for better thermal performance. 
2. Just that, they need it for thermal performance.

Of course, the answer is the last one, the extra cores based on the very same Coffee Lake architecture that well pretty much is Skylake when you think about it, will produce more heat and that is a challenge to deal with. But yeah, in the end, it is good news. It should be possible to reach 5 GHz overclocked (not on all cores), but that is the word on the floor. According to a well-informed user in the Coolaler forum, the Core i9-9900K runs at 4.7 GHz on all cores and at 5 GHz on two cores. The Core i7-9700K also has eight cores, but has to do without hyperthreading. And let me reiterate, several Intel-related sources have independently confirmed that Intel connects the metal lids to the processor via solder. This is only the case with the two Octacores, the Core i9-9900K and the Core i9-9700K. For the smaller models with six cores like the Core i5-9600K, the manufacturer still seems to use the classic thermal compound.

From what we hear, the release date is expected in September 2018.
