This appears to be working as expected. Here is a graph [0] of the Intel Power Gadget while I ran Cinebench. They are not the same length because it took longer before the update and I cut out the parts before and after. Pretty striking difference IMHO and it never went below base clock after the update. I was worried about my i9 but I'm not anymore. Also if anyone is wondering it went from 780cb -> 860cb but I wouldn't put too much stock in that since I've got other apps open (same apps for both tests) and 3 external monitors attached. Some people report 1100cb score after the fix.

- onewhonknocks 8y agoThank you for letting us know.
- satysin 8y agoHmm my i7 8850H gets 1024cb[0] so I would expect your i9 to do better than 860cb even with some other stuff going on at the same time. https://i.imgur.com/o83CM33.png https://i.imgur.com/o83CM33.png
- joshstrange 8y agoI don’t doubt it can do better, I just have a bunch running in the background and this was right after startup (after applying the patch).
- DennisAleynikov 8y agoGlad to hear the fix works out for you. It's rare that apple will fix something like this so fast, but it's entirely possible this just slipped past QA since apple doesn't test throttling that thoroughly it seems.
- ams6110 8y agoWhich is strange if they're not, because their sleek and slim designs would seem to allow a very minimal margin for error on heat dissipation. you would think that would be the subject of quite a bit of testing on the hardware side of things.

- cyphar 8y agoGiven the history of graphics issues (many of which where related to heat causing capacitors or GPUs to misbehave) I'm not at all surprised that their testing of heat-related issues is subpar to what you would expect. The fact they sell fan-less machines despite a history of heat-related issues in almost every solid-aluminimum-construction laptop they've released seems particularly negligent to me. EDIT: If you'd like more information than just heresay, watch some of Louis Rossmann's videos on macbook heating problems (the video on tantalum capacitors is particularly interesting).
- white-flame 8y agoBut how do the temperatures differ before & after the update?
- joshstrange 8y agoThat I can’t really answer, I didn’t do a ton of benchmarking other than the CPU which I had seen that jagged pattern before so to see it so smooth and not fall under base clock was all I was looking for.
- grecy 8y agoDoes the fan seem to run more / higher rpm now?
- joshstrange 8y agoI have not noticed that, and I did pay attention to that while running Cinebench.
- mirimir 8y agoFrom what I've read, it's stable at ~92°C.[0] That seems damn high to me, but then I'm most familiar with desktops and servers, where you can cool far more aggressively. So is long term ~92°C hard on CPUs? 0) https://www.cnet.com/news/apple-macbook-pro-speed-throttling-patch-tested/ https://www.cnet.com/news/apple-macbook-pro-speed-throttling...
