Are you playing on Mac or Bootcamp and at what settings? On Mac I can barely get it to run at all on my i9. When it finaly loads I'm already out of the bus and half way the first circle. On Bootcamp it runs good for a minute or 2/3 before the GPU starts throttling.
Got a tip for us?

Optimal CPU Tuning settings for i9 MBP to stop VRM throttling / Explanation of Apple's Engineering F

Can you please try on a VM (on Mac)? Technically this should take advantage of Apple’s patch.
Maybe Parallels offers a trial?
Exactly with better matched power & cooling solutions this is what you would be seeing...
CPU (8750H) holds full Turbo at 3.91GHz on all cores, pulling around 60W until the short term Turbo limit (PL-2) is hit at 28 seconds. Cinebench R15 is too short a test, equally once the CPU rolls back to the steady state frequency (PL-1) at 45W it should still hold at around 3.4GHz under full load.

And if they want a size/weight target for this, they could use the 2nd generation 15" (unibody) MBP, which was 5.6 lbs. and 0.95" thick, and which pros were happy to carry around at the time. This gives Apple's engineers an additional 1.6 lbs. and 0.24" to work with (vs. the current model), which should be plenty to significantly improve the thermals.
In addition, the ports they'd be able to bring back to this hypothetical pro model (including SXDC & USB-A) would take the slight sting out of the added weight and size, since the pros would no longer need to keep track of and lug around so many dongles.

Definitely a classic design that aged very well. Those 2012 and 2014 models are still in hot demand.
I'm fairly sure you could make any macbook or macbook pro from the past 3 years hit 100C.
I'm not disputing that
. They very well could have. I guess I was spoiled at how cool my 2012 rMBP ran.
Darn it!
Asus GL703GS - i7 8750H, GTX 1070, 32Gb @2666, M.2 NVMe SSD & SATA SSHD, 17.3" 144Hz at a massive sub 3KG
It's a gaming platform, now repurposed as my primary engineering tool. Downsides battery life is plain poor, no 4K option and no i9 option. Pity as it has a ton of thermal headroom. Asus was smart opting for 12V fans with more blades than a regiment of Ninja's
With it's power/fan profiles it can be literally dead silent with the fans completely shutdown under basic productivity, then all the way to cooling the full 230W TDP.I've ran OCCT stability tests on it for hours on end with the CPU at full tilt, 100% stable at 3.3GHz/3.4Ghz, literally desktop performance in a realistically portable package. Crushes everything I throw at it
This is what Apple should have done, unfortunately Apple's not concerned about how much revenue it's customer's can potentially generate, just itself
equally a circular argument... Not real big on benchmarks, that said how else to compare comparative systems. In real world workflows the GL703GS simply tears through everything, really pleased...

I'll try Parallels for you this weekend, I have it installed but personally don't have good experiences with it on game performance.
I found the results in Bootcamp to be really odd, so I've kept digging at what the problem could be. As temperatures weren't high I thought that there should be another reason as to why its throttling. As a result I ended up at http://bootcampdrivers.com which let me update the drivers for the card. I've just run some tests and the good thing is that the card doesn't throttle anymore, which makes me believe that it's a driver issue with the current official drivers for Bootcamp.
Downsides are that the card doesn't get fully recognised as a 560x but as a Radeon Pro card, and that I can't check its temperature anymore. I can keep the CPU running op to 25x multiplier (so around 2.5ghz) without problems though and framerate at 1920x1200 is relatively stable at 55-60fps.
I really hope that others are able to test if they have similar problems and test whether this works for them.
I'm not disputing that
Shame, you missed all the action by just a year
2011 15"cMBP 103C no problem as long as you want, or at least as long as the dGPU could hold up I just used to let it rip and hope for the best, literally cooking for days one end. I honestly believe that with a spot of oil frying an egg on the base plate is possible Q-6
Sounds good. I only asked about the VM because I thought it was general knowledge default Bootcamp drivers suck at gaming. I thought you had drivers from the bootcampdrivers website already downloaded. Really happy to hear games are working good on Bootcamp. Thanks for testing

All of this is slowly sucking me into Hackintosh world. I DO love macOS.
I always thought about installing Hackintosh on my desktop PC because I am never investing in a branded desktop, Apple or not, but while you can get one running now, you can’t guarantee a big free experience when updating or upgrading to newer macOS in future :/
Old hat for me as retrofitting macOS (Sierras and now Mojave) on "unsupported" macs (macpro 3,1 and mbp 5,3) has been painful but reasonably successful. Just a matter of time before I take the full plunge with my own rig. I'm not a big studio who could care less about the price tag, every time I consider the charge to customize the mbp I really want, I pause. The recent issues haven't helped. Think Apple is driving away old die hards like me.

Not an option for me, I'm pretty much OS agnostic these days. As long as W10 behaves I'm OK with it.
New. MBP's are a step in the right direction, equally Apple should have bolstered the cooling solution to take better advantage of the 8th Gen CPU's.
Right now I'll let the dust settle and Apple work out the kinks, and it's entirely possible the performance may come up a touch more with further firmware updates.

Hi to all,
I can't read all this, for now, and I have to make a decision in 24hrs ...
Shall I, or not, to buy the I9 vs the I7?
Is Apple addressing the issue or not? Meaning shall we ever get the 'full power' of the new i9?
Thanks in advance for your remarks.

Short version: Apple released a patch. It works well, and the underlying problem is, in fact, solved. An i9 will have much greater marginal benefit in a desktop vs a more thermally limited laptop, but there IS noticeable performance improvement of the i9 over the i7, in some use cases more than others.
Whether or not a few % performance bump, maybe, depending on what you do, is worth while to you for $400 is for you to decide. I'm happy with my i9, but I think I would be perfectly fine with the i7 as well.
They addressed it few days after the issue was first discovered and discussed (assuming that you are talking about the original heavy throttling)
We certainly won't. If you want to have full power of the i9, you need a computer that is 2-2.5 times heavier and 3-4 times thicker...
You can have roughly 70-80% of that power.
The difference is not large, and it depends on what you do, but the i9 does seem to come with a slight advantage.
Thank you so much for your reply, concise and direct.

Thank you for your reply.
As I don't work as much as I used to, I intent to replace both my MBP i7 from 2014, and my Desktop, also an i7 from 2013 (not Apple but running MacOS). The difference is that the latter as 32 GB of RAM, but nowadays I don't see much use of the extra 16 GB, but it could be an issue on some scenarios that I used to work on.
I think I never go back to work as I used to, so, maybe you all are right, but in here the differences are:
+340€ for the i9 or 480€ for the extra 16 GB of RAM, on the 2.6 i7 model.
Well, lets see, Thank again for all of your opinions.
Regards.

Not a good reason to make a buying decision. Anything could happen in mean time. And with thermal issues I would have a note of concern on longevity of i9's - which would not be great for resale value

Q-6
I feel you. My 2011 ran hot for 7.5 years before it kicked the bucket (well, for the second time. The first time Apple fixed it for me)! I didn't do it for days on end, no, but certainly for 3-4 hour gaming stints on the regular. This 2018 feels cool and quiet by comparison, ha.
I'll just follow up, as the Original Poster of this thread ...
Personally, with the official patches from Apple applied, I am very happy with my i9 MBP. For my workload, which is very bursty, there is a very noticeable speed improvement over the 2017 MBP.
I don't have any experience with the 2018 i7 model.

I have the i9. I'd have been unhappy with the i7. Simply for the reason that I'd know there was another one I could have had that's a bit faster :/
Yes. I'm shallow. Don't hurt me.
