Well I’m not working 100% of the time. So in those moments I’d like to get as good a battery life as possible.
Not saying that's what's happening here but, as a general technical point, I thought 800MHz CPU clocks could also be a response to overheating discrete video cards.
Mine is i7 2.2
I tested it with Dota2. Unfortunately it throttled as well. Every a few secs the fps in Dota2 dropped to 10~20 while CPU frequency dropped to 0.8. I already set the settings to lowest. It's impossible to play the game.
Even my 2013 13'' mbp can play Dota2 smoothly under low settings. My friends' 2017 15'' mbp can also play the game. Why 2018 mbp 15 can't ?
I think the machine just can't handle the heat when CPU and GPU both working.
Honestly, I can bear with the soft keyboard and the useless touchbar but take away my occasionally fun of gaming on mbp eh.. I have to reconsider my dicision of buying this.
I know mbp is great for work not gaming. But ****** GPU + 6 core CPU which this machine cant handle it's just getting worse not better.
That’s what I was thinking.
I’ll probably pull the trigger on that. Should be fast enough for music work even with huge track load and lots of heavy plugins running.
This I find strange. Even with throttling it shouldn’t be as unplayable as you mention. I have my brothers playing Dota2 on their Airs.
Could this be another software optimisation issue?
It will make it unplayable if there isn't enough power available to keep the CPU at at least 2.0 ghz while the dGPU is active. When the xps 15 9550 would get VRM throttling, the voltage available would drop to 8-12W and that often meant 800MHz clock speeds. That low frequency will cause any modern 3d game to become unplayable.
The 87W power supply is likely starving the GPU and CPU when both are in use because of coffee lake's higher power consumption. If you throttle the CPU down manually by disabling turbo, I think you should be able to play dota 2. If it still happens even after disabling turbo, then I think the 2018 is falling victim to VRM throttling. I think the first solution will work, but if it doesn't, then the machine belongs in the trash, truly.

Anyone with a 2.2ghz or 2.6ghz model able to run this Xcode benchmark?

Anyone with a 2.6GHz 16GB and 32GB model able to run an After Effects benchmark?
Really would love to test my most used application.

The build times on that MacBook Pro Retina, 15", 2018 i9 look pretty dang good.
Right? It does appear to be a fairly small project.
Waiting on John Poole to complete his testing. His initial tests showed i9 and i7 2.6gz neck and neck, with i9 actually somewhat slower in some tests:

In the meantime, I ended up ordering a 2.6gz machine, since my workflow includes Unity3d, and everything I’ve seen so far leads me to believe that even if Apple tweaks their voltage/wattage and fan curves approach, i9 will still suffer from thermal issues when taxing both CPU and GPU. Figure I’ll spend the extra $300 on a Caldigit T3+
you're opting for just too many compromises in my opinion at that point
Still haven't answered the question. Does the i7 have better battery life than the i9 when just browsing the web?
Using volta:
power limit to 45w, without Turbo Boost - CPU around 2.2Ghz, Temperature 67C
power limit to 45w, with Turbo Boost, undervolt a bit - CPU around 2.9Ghz, Temperature 72C
Dota2 mid settings, 60hz, battles drop to 40-50hz
It works!
Been watching this thread for a while as I'm trying to decide what to replace my 2012 Retina i7 2.6 with (either the 2018 i7 2.6 or i9 2.9)
I run primarily Lightroom and with Canon Eos Utility tethered at photo shoots, (Eos Utility ramps the fans up to 100% the second live view is on, and I use it to line up my shots, but slows down everything significantly), then I do edits, some HDR merging, then export a few dozen files at 3 sizes. I'm thinking this workflow is going to really max out the CPU and am curious if the Cinebench test is a good analogy to lightroom exports and which would be faster (i7 2.6 or i9 2.9).... if I'm charging by the hour ... maybe slower IS better in this case ;/
So far I've found this, which seems to suggest the i9 is going to throttle pretty hard with Lightroom similar to Cinebench on default fan and power settings...
https://www.reddit.com/r/macbookpro...perience_with_the_i9_mbp_and_adobe_lightroom/
Really curious when/if there will be a firmware tweak from Apple, what gains it could realistically bring, and if the i9 is going to pull ahead enough to make it worth the $300 upgrade.... It seems like notebookcheck have had significant improvements using Volta (which is limited to 45 W, and not dynamically controlled), so far only tested on the 2.6 i7 though.
On another note, who is willing to take a hole saw to their brand new $4000 MacBook Pro and do this mod:
https://medium.com/be-expert-101/my-macbook-is-too-hot-89afa1a0079a
It might just do the trick ... perhaps just the thermal pads on the heat pipe touching the bottom cover could give it the extra bit of heat dissipation (right into your legs!) ....

I would also like to know this. Apple hasn't even made the brightness control work on the new Macbook Pros in Mojave beta 4 so I doubt they've done any optimizations.
Same here. Peeling apart the betas for a while now and have no indication that this issue is being addressed in Mojave. In fact the new 2018s just recently made it to official « supported » list...
But talosive also slated the new macbook on a live stream he just changes his tune to get john to notice him lol he isnt a real apple sheep
[doublepost=1532324201][/doublepost]Im getting the i9 today maxed out ill so real tests, people are mad to think apple would release a slower cpu for extra dont believe all the hype the i9 is the best period
You're WELCOME
Definitely wait for the end. This guy is EPIC
