Beat me to it.
Ive been using this thing for most of the morning today and I gotta say its FAST. One thing I expected to be quicker would be applying filters to some large-ish datasets in Numbers. Its faster than my 13" 3.5 but I kinda expected more with 8 cores.

Yes, because Apple changed the thermal paste for the cpu, FINALY they put a decent one after 2 years of issues especially with the i9I received my 2019 yesterday, i9 2.3GHz, Vega 20. In normal use at least, it seems to run significantly cooler and quieter than my 2018 i7 2.6GHz, 560X.
I haven't tried pushing the gfx hardware yet though.

Yeah, TIM (you know, the compound, not the other one) has nothing to do with it, laptop still maxes out at 50-55W. But it is a lot faster, higher clocks at this power level - only voltage change can do it.Little more than that methinks, some serious under volting more likely...

The die is naked in laptops, soldering doesn't apply.I think you mean Intel's STIM technology. https://venturebeat.com/2018/10/08/intel-solder-9900k-i9/

The guys from LTT believe Apple implemented some fancy undervolting techniques, since the behaviour in Bootcamp/Windows is very different from macOSYes, because Apple changed the thermal paste for the cpu, FINALY they put a decent one after 2 years of issues especially with the i9
I rely on Mac OS and i have about 15 users.We will see if and when. For the most part we should be hoping for none, outside of the usual "I spilled" For those that use and or rely on OS X the Buttery Keyboard issues bring absolutely no joy whatsoever...
Q-6
Its called CPU whine. Some of my models over the years have had it, some not. In the case of my new 2.4 8 core, no whine to be heard. Touch ID button solid as a rock.so I just brought home the 8 core base model.
two things:
a) I can actually hear the CPU when it runs, it's a little high pitched, quick stop/starting sound
b) the touchID seems a little wobbly, I tap it and it makes a plasticy sound
Either of these normal based on others' experience? Thanks!
Do you have iStatMenus, or something else that would show the CPU voltage? If you have, could you check what the voltage is while running the CB20, it should be pretty constant at the same frequency, so just make a mental note what the GHz are.
Those results are very good, it scales almost 1:1 with number of cores, while power remains the same. On the 6 core MBP I'm getting 2550 and a number of others were getting the same. Using my 6 core desktop as a test bed, to get 2550 I have to run at 3.4 GHz. To get 3250, like 8 core MBP, I need to be at 4.25 GHz. You're getting this at ~3.2 average (trying to spread to initial spike over duration of the test), so the IPC seem to be the same as the 8th gen, but the performance/watt insanely improved, to the tune of ~25%. Looking at the 9th gen 6 core results doesn't seem like there is anything in the architecture itself, cooling and thermal ceiling the same, so Apple has to run the 8 core at much lower voltages.
My friends 2.6 6core just arrived. And it got a 2338 on CB R20 in a warm-ish room.

Thanks, good thing that room temp was high, it was much easier to run some comparison tests with the 6 core. Looks like -65mV undervolt on CPU by Apple, pretty conservative, but still yields good results. I've set my GS65 to 0.94V at 3GHz, and everything scales beautifully with 8:6 ratio - 38W, 2280 score vs your 47W and 3030. More or less, because it wasn't constant on Mac. If you'll be bored, you could disable turbo (with an app) and run this again at 2.4 GHz flat - then we could nail exact number.Back to the 8 core 2.4-
Like this? The room is a good 10 degrees warmer FYI. Interesting how iStat and IPG report different values for the CPU frequency. Maybe just a biproduct of out of sync polling rates.
Yeah I’ll get it in the cooler room tomorrow and re-run as well.Thank you for your post. Could you please check the idle temperature for the 6-core? I saw a video that the 8core idle temp is ~35°C, 10°C lower than the 2018 model. What about the 6-core?

On the 2.6 6c 2019 - Fluctuating very slightly around 29c at 1.3ghz with nothing open just looking at the desktop. The room is about 22 degrees celsius/73F.Thank you for your post.

Thats funny. You are right. It does only show 6 cores and I do have 8. Look above in the visual meters and theres 8 bars. I wonder if they just havent updated iStat yet? Just looked in the prefs and I don't see a way to add 7 and 8.I see in your screenshot that iStat Menu shows only 6 Cores but you have i9-9980HK 8-Cores.
Am I wrong?

Yeah that sounds fine. Congrats on the resolution.Well, I went back and swapped it out. New one doesn't make a peep, even with dropbox pegged the cpu with 130 threads. keyboard is getting kind of warm, but I guess that's the cost of indexing and dropbox updates the first day.
