If it has to remain below 50c to turbo boost this thing will never reach 4.8ghz...

The Intel Core i9-8950HK is a high-end processor for laptops with six cores based on the Coffee Lake architecture and was announced early 2018. The processor clocks at between 2.9- 4.8 GHz (4.3 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. The 4.8 GHz can only be reached using the "Thermal Velocity Boost" which allows one core to boost to 4.8 GHz (+200 MHz) as long as the CPU temperature is below 50°C. Multiple cores can be boosted +100 MHz below 50°C.
 
Would be interesting to see the first ifixit tear downs, don't think they went all over board with figuring out a new or better cooling for the cpu. Might be wrong though. But wouldn't get my hopes up, never see my cpu temp below 50°C as soon as start "using" my MacBook Pro.
 
4.8 ghz in a laptop is a marketing trick, it will work at that clock for 3 seconds then throttle to around 3ghz which isn't bad either.

Maybe Linus will liquid cool this one just like the 12” MacBook LOL. But the heat pipes on rMBPs are pathetic. I feel like it’s gonna be hard for this to run at maximum performance unless there are significant changes. We’ll have to wait and see I guess
