2018 i7 MacBook Pro throttling discussion.

’m getting 95.61fps on the 560X. How about your 555X? And regarding the Dell, I guess this shows that while Intel is not blameless in this, Apple really screwed the pooch on cooling this year.

That is not much of an improvement from the 560. I get between 92/93 - 87/88 fps on multiple runs... had registered a high of 99 once, but not been able to replicate it

I'll be doing that myself. When I bought the Razer Blade, I spent days running tests and seeing what the thermals were. For the most part they were decent, but to get to better battery life and I play with the performance settings. I'm expecting to get better temps (lower end GPU will cause less heat), and better battery life. I will run a firestrike benchmark and compare it against what I got for the razer but I really believe the results will be significantly lower. The razer is after all a gaming system and the MBP's GPU is no where near that.

Excellent, please let me know how it goes.
 
Does anyone have comparisons between the i9 and i7 in regards to real world use in Adobe CC software? Other than the D2D video I haven’t seen comparisons of render times from an application like After Effects between the i7 and i9 in this years models.

I currently have an i9 but was considering swapping it out for an i7 if the truth is that the i7 performs better than the i9.

If anyone could test After Effects with this test file I would love to compare the 2018 i7 to the i9 in render times. mediafire.com/file/qgoacxne6567wxn/AE_Test_2016.zip

Why does Apple do this? No one can tell me they didn't know this would happen.

Whats the point of putting a really high performing CPU in these machines if you can't unlock its full potential for an extended period of time.

The chassis redesign cycle isn’t up yet. And people were clamouring for the newer CPUs like the competition has. If they didn’t, they’d take criticism and likely lose sales.

Except shoving more power, and thus, more heat into a non-modified chassis has had the expected result.

Lose-lose really.

That they thought the real pros who need consistent high performance wouldn’t recognise their decision is the real shame here.

Are these 6-core i7 machines (the 2.6GHz specifically) warm to the touch when idling, word processing or using Photoshop or Illustrator?

I can’t comment on Photoshop or Illustrator, but for idling, word processing and web browsing I can. The idle temp seems be about normal, maybe a little higher than previous Mac notebooks: around 115-120F. Word processing keeps it in the same ballpark. Web content can cause the machine to enter the 130-140F area. It’s warm to touch, but not in any way as bad as you may think. Slightly warmer than my previous non-TB3 Retina.

2.6GHz i7-8850H here.

Do you have access to After Effects to run a benchmark to compare it to the i9 model?

They should have a put a newer Quad Core with a lower TDP. From what I’m seeing, the Quad 13” on Geekbench just as fast if not faster than the previous 2017 15” CPU wise. (Does anyone know if they’re thermal throttling too?) At least in that case we could brag about having exceptional battery life. Instead we’re left with CPUs that, while look faster on paper, are actually not that significant of a bump thanks to the lack of cooling. And from what I’m seeing on the GPU side, it doesn’t look like the 560X is that much better than the 560 or even the 555X.

Sorry, not an Adobe user in anyway. Final Cut for editing and Motion for the occasional animation when needed.

Oh I have FCP X. That should be close enough to test.

Would you mind running this benchmarK? https://blog.alex4d.com/2013/10/30/brucex-a-new-fcpx-benchmark/

Edit: Nevermind. That test doesn't seem to tax the CPU enough. Does anyone have a FCP X benchmark to compare?

I am very curious about how the i7 (2018) and i9 (2018) compare under real world circumstances.

So what I am gathering here is if you want a fast sprinter this machine works great and if you need more elongated CPU power currently it throttles too hard to be useful for that. Is that about it?

Would someone with an i7 2.6ghz mind reporting (estimating) how the computer behaves (would behave) with 1 Parallels VM open (8gb and 4 vCPUS) to run MS Office, Chrome and a few other Windows apps, as well as some Mac Apps (Safari, Note, iMessage, Spotify, photo, etc)? Would this kind of setup make the computer throttle? Get hot? Kick on the fans?

Am obviously no power user, but prefer the computer to remain silent, and would like to try the bigger screen as my eyesight declines.

Thanks in advance and apologize for the noob question. Have never had a 15", and am still using a 2013 13" MBP with Core i5 2.4.

I would've been happy to test, but as soon as I booted my VM for Windows 10 it started downloading updates causing the CPU to warm up to a toasty 208F and have the fans spin all the way up.

Oh, Windows. You never change.

My MBP just got delivered last night, and so I'm setting it up this morning. I have it sitting next to my iMac as I have dropbox sync up and I start installing other apps, when I noticed the temps spiking :eek:

2018-07-20_06-41-22.png


I just finished installing Macs Fan Control and put the fan speed at 3,000 and for idle activity, the temps have receded to a respectable 42c I know there's some activity behind the scenes with spotlight and what not, but still looking over and seeing such high temps, was (and is) alarming

So your 2017 hits 100c at one point? That in a weird sort of way is a bit encouraging. Below's mine and

I seem to be getting better numbers from my 2.2 base model then your 2.6 model :eek:

I'm using Macs Fan Control, but even without that, I'm seeing CPU only numbers in the 920 range. It spikes right up at 100c and then starts banging around the 90c range until it recedes back to something more respectable.
