Tested: Apple's patch fixes the thermal slowdowns in the 2018 i9 MacBook Pro

Apple targets thermal performance issues on 2018 MacBook Pros with software update
dws-2 said:Very happy news. I just need to wait for confirmation of this.
Oddly, I don't think people realize what a great update this is. The speed alone is great, but there really is a lot packed into this.
First, I don't think people appreciate the security aspect. This computer is almost as locked down as an iPhone now, so if I lose it, I no longer have to worry about anyone getting my business or personal data. That alone is worth a lot to me.
Second, true tone is really nice for someone who stares at a computer screen for 8 hours a day.
Third, the RAM!!! 32 GB makes running virtual machines much better, and the two extra processors don't hurt, either.
The last big thing is the keyboard, but that's still uncertain. I'm seriously thinking of updating from a 2016 MBP with touch bar, but I'm waiting to see how well the keyboard seems to be standing up. The keyboard on that 2016 drove me crazy until the second replacement.
In short, with the possible exception of the keyboard, this is a very, very nice laptop.
Exactly the same speeds with encryption on or off, even shortly after turning encryption on.
The 2017 model, on the other hand, took about 20 hours to encrypt the drive, with available speeds of 1300 read and write during encryption.
With FileVault off, we saw 2000 MB/s write and 2700 read for the 512GB model.
After FileVault encryption completed, read speeds dropped down to 2150MB/s.
2018 MacBook Pro storage speed is completely unaffected by FileVault. (1150 write speed and 2500 read speed on 256GB SSD) -
Comparing the Dell XPS 13 9370 versus Apple's 2018 13-inch MacBook Pro with Touch Bar
tjwolf said:You mention the XPS has double the SSD storage - but you didn’t give any information about their relative performances. Not all SSDs are created equal. Personal example: started a new job last year and they gave me a super powerful Lenovo Windows desktop w. 64gb RAM and a 1TB SSD. A complete build of our application - very IO intensive activity - took 15 seconds. Very fast compared to my colleague’s hard disk based times (30+ seconds). When I needed to replace it with a laptop, I got a 2017 15” MBP with 16gb RAM and a 512gb SSD. It builds the same application in 7 seconds flat. Because the SSDs in Macs are the fastest on the planet.

Tested: Thermal conditions in the 2018 i9 MacBook Pro dramatically hampering performance

There are two fundamental problems here from my point of view:
1. Apple should not offer the i9 as an option if it has no real advantage. A big part of the advantage of Apple is that they don’t dump design decisions on the user.
2. Apple needs to offer better pro desktop options. The iMac pro is ok but we need a real pro desktop. If there were a real pro desktop option then people would be more willing to accept the compromises inherent in an elegantly designed laptop
If they did not offer the i9, Dave Lee and pretty much everyone else on the internet would endlessly whine about it. As it is, shipping the i9 was the right decision even though I'm super disappointed with this and won't get one as planned now.
It's possible Intel will fix this by providing better chips to Apple, or Apple can do some magic with fan management - it's still possible there are bugs in the fan management software and it's just throttling more than it needs to be.
@AppleInsider - I would love for you to do a processor test that doesn't use the GPU as well.
Because if you use the GPU, there's a second massive heat source in the system. If you run without GPU, you should see less throttling?! I am not sure Adobe Premiere and Cinebench are using the GPU, but the article seems to imply at lease Premiere does.
In my own tests trying to play a game on my MBP, just running the GPU would nearly overheat the system, didn't even need a lot of CPU power for that.

The i7 (advertised at 2.2GHz base & 4.1GHz Turbo Boost) stayed at around 2.3 - 2.6GHz average clock speed during back-to-back CPU tests in Cinebench R15.
Reached a peak of 3.8GHz when the test started.The i9 (advertised at 2.9GHz base & 4.8GHz Turbo Boost) was at around 2.4 - 2.8GHz average clock speed.
Reached a peak of 4.2GHz when the test started.
