Not at all, more about running simulations and or statistical analysis up to 40% faster. I'm confident that if Apple produced a notebook with this level of performance many profashinals including myself would own one for the same obvious reason.
Point in fact, it's possible to produce powerful notebooks that don't massively throttle or weigh in at 10lb...
Q-6
Here we go: i9 vs base i7. Kind of the same results.
As I have expected the i9 to throttle a lot I went with the mid-range, higher clocked i7. Guess once a fan-curve update is out, the higher clocked i7 will perform just as the i9.
Any other fellow Unity devs on the thread, that have a 2018 MBP, any flavor? I'm seriously in need of an update - still rocking a maxed-out late 2013 15". I know any of the 3 models will crush what I have now, but I don't know if spending the extra $ on either the i9 or i7 2.6Gz will be $ thrown away. I'm curious if playing a large scene in Unity pegs the CPU/GPU, and whether throttling will play an issue when building a project in Unity or building XCode project.
apple is gonna have a huge lawsuit if all this i9 issue is not fixed, they cant make us pay more for a slower machine
Very interesting video. Thanks for sharing. It looks like they tested the 2.2, but does the 2.6Ghz fair as well as the 2.2. I'd really like to see a comparison of render times in applications. Cinebench scores are a good indicator, but want to see how they compare when it comes to real-world scenarios.

Meh...if it ends up in a class action lawsuit and Apple agrees to settle, it will end up like what happened with Nvidia and 970 debacle: consumers will end up with morsels. In the case of the 970, consumers ended up with only $30. So lame!
So yeah, it isn't gonna be as epic or as huge as you think. Their rep is gonna be damaged, sure, but look at Nvidia, people are still buying their GPUs in huge numbers. Same thing is gonna happen to Apple. Slight PR damage, nothing else, unfortunately.
THIS. If the 2.6 throttles to 2.2 as well, we may as well stay with the base model. FWIW I believe the Razer Blade 15 uses this 2.2GHz cpu exclusively (at least one with the same base clocks & turbo speeds) so that's a plus in my book since it's good enough for gaming and apparently runs fine in a very similar chassis (they use a better cooling solution though, but also consider that it's housing a 1060 or 1070... anyway, I digress).
Exactly this. I am trying to decide whether to return the i9 and possibly swap for an i7, but if it's also having issues hitting the base clock speed then I really should just get the 2.2Ghz...
Increasingly believing (after reading all too many pages of these threads the last 48 hours or so) that the sweet spot is a 15" 2.2 GHz with 512 GB SSD (or maybe 1 TB) and 32 GB of RAM.
My estimation is purely based on personal experience on thermals for different (server) chips with different cores and boost clocks. Given the current situation, Apple will most likely update drivers so that the fan-curve kicks in more aggressively.
As the i7 is consuming a whole lot of power less than the i9 under full load, my best guess is that the new fan-curve will lead to a i7 that reaches it's base clock under full-load with no thermal throttling. I honestly do not see any chance that this will happen to the i9 without any thermal-paste replacement or even greater physical fixes.
Plus: With the Mid-i7 model you get a slightly higher boosted CPU for about 150,- € more in an elsewhere identical build. That's the sweet spot for me. If 256GB storage is an option though (it's not for me as im running a late 2013 13inch MBP with 256GB and im really struggling with the storage space), the base model will give you the best bang for your buck.

See above. For 250€Ish more you'll get the higher clocked CPU and GPU
Long time listener, but first time poster. I really appreciate all the testing provided in this thread. I too am interested in an AE test of the i7 if anyone has time.
Seeing all the testing here and on YouTube, it does seem to me that there is the chance for SOME cooling optimization on the part of Apple? Maybe? I say this because load tests on my current 2014 Retina 5K and the 2016/2017 models seem to settle into a clock value and stay there (even if throttled). For example, when exporting in Premiere, my iMac throttles down to 3.6 GHz (from 4), but it holds that value through the whole export (20 min 4K test). The data I am seeing from the 2018 is all over the place. It doesn't seem to be able to achieve ANY steady state, which seems like an optimization problem to me.
I am no means a computer expert though. I am just going off my years building a pH stat system for my graduate work in Environmental Engineering.
Very interesting.. I just noticed the Geekbench benchmarks show the three new six cores as being almost the same! https://browser.geekbench.com/mac-benchmarks
Seems that's the consensus across sources. The only open question I'd like to see more thoroughly addressed is comparing the models in sustained single core performance (I've seen some users here doing that with their own machines, which I appreciate, but side by side comparisons is really ideal).
I’m glad I’m not alone, and that was the conclusion I reached as well. I’m thinking upgrade the video card too. Do you have thoughts on that?
No, you need to run more intensive tests such as OCCT or Cinebench R15 repeatedly.
Q-6
Not up on my Euros, but here's what I show in USD, although I may have gotten it wrong:
560X GPU / 32 GB RAM / i7 2.2 GHz / 512 GB SSD = $3,478
560X GPU / 32 GB RAM / i7 2.2 GHz / 1 TB SSD = $3,878
560X GPU / 32 GB RAM / i7 2.6 GHz / 512 GB SSD = $3,578
560X GPU / 32 GB RAM / i7 2.6 GHz / 1 TB SSD = $3,978
Edit: These prices include AppleCare ($379 for the 15" model).

Yes, forgot to mention that. Definitely the 560X. A little more bang for not many more bucks (relatively speaking).
2.6GHz 6-core only slightly faster than 2017 (2.8 GHz, 555) entry-level

“50% more cores for 13 % more performance.”
“The performance drops further after the initial run and the average result after 36 runs is just 832 points. This means the advantage over the MacBook Pro 15 2017 with the quad-core Core i7-7700HQ is just 13%, and the difference should be even smaller the more runs we perform.”
I am very curious about how the 2018 entry-level (2.2GHz 6-core) compares to last years entry-level? The MacBook Pro 15 2017 (2.8GHz, 4-core, 555) or even the 2.9GHz, 560? Would be interesting, especially for potential buyers of the 2018.

Max's reviews are the real deal... this is what I've been waiting for.
This guy is also gearing up to release a massive review and comparison with different editing programs, codecs in/out, and all thermal supervised. He's also comparing the different models, i9, i7s, etc.
