Wondered how my 2015 i7 MBP held up to the Prime 95 torture test.

I note two things.
First, the chip is running at 1.1 Ghz.
Second, the chip is consuming 10 W.
Cool, but slow. Which CPU is this?
Wondered how my 2015 i7 MBP held up to the Prime 95 torture test.
Resale, futureproofing, workload overhead, and, “just because,” are all valid answers.This begs the question: Why did she pay more for the i9 if she's not going to utilize it to its full potential?
Then I got to thinking, maybe the two extra cores at, say 80%, utilization (and without throttling down) may outperform a quad core at 100% utilization. Never really tested this theory to see if there's any merit to it.
Or how about a putting the i9 in a portable Mac Mini with great cooling and battery life, and using a thin new MacBook as the keyboard and monitor? I’d buy both immediately.Silly Apple.
Put it in a thicker chassis or a 17" form factor, to fully utilise the CPU.
That's what the Pros should get when they're already paying for the Core i9 upgrade.

Or, a little girl with an iPad is wondering why the old lady next door is calling her iPad a computer.Apple has forgotten what a computer is

They should've designed the cooling around it, or use a different chip (ryzen?), simple as that.But it is Intel's fault for designing a CPU that seems to run away thermally so easily and with such major issues as Intel seems to keep having.
Apple can only work with what they have.
The AVX [not sure it is available on the i7 even yet] instruction set (which up until a version ago was only on Xeon) [which I think has to do with 512 bit floating point calculations] seems to be easy to cause throttling (not overly knowledgeable about that - apparently Adobe Premiere might use them if they are available). The iGPU typically takes up 50+% of the die space - so if you are a power user not worrying about power - you might be able to take that offline during peak CPU usage [might require a CPU microprocessor update to allow it], there is also a possibility that the fan profile could be updated which might provide extra airflow and help, then it might also be an early manufacturing process Thermal Paste issue (this happened before and was corrected early on in the production cycle). So as far as I can guess, might be the chance of software solutions... but all this is just theory.The only way I can think they'll be able to achieve such a "fix" through software is by limiting performance.
Or the actual computing power could be right next to the laptop, in a MacMini with its own battery, tons of ports, a fan, big heat sink,IMHO, we are nearing the limit where performance is severely impacted by physical limitations (thermal, space constraints, comfort, and so on).
People want thin, light and sleek but with hyper computing capabilities. Personally nowadays I prefer to just get a cheaper and lighter model, while remotely access the actual computing power that lie somewhere at home on a desktop or on the cloud, where the performance can be limitless and I do not need to spend very high costs upfront.
As in running the fans at higher speeds? You mean it doesn't do that now?Or by better and more responsive fan management. Too many questions. Too many people aimlessly theorising and blaming. Not enough answers. Patience is going to be how I handle this issue.
You called a guy who owns an iPhone X and says he “likes” Apple “anti-Apple” because he wrote something about his experience—and documented it with data—that doesn’t support your blind belief that Apple can do no wrong. You also made a factually incorrect statement about what he has and hasn’t posted and tested.By "balanced perspective" you mean "eat any sh-- YouTuber or the press makes up about Apple".
Seriously, go live in your bubble.
To be fair, this isn't so much Apple's fault as it is Intel's. Intel has really dropped the ball in the past couple of years. If they don't right the ship soon, AMD will take over the CPU game for a while. They are late with everything and are having lots of trouble shrinking the dies.
I believe you think you're smarter than you are.
I don't think you really know if your computer is running at 100% capability, 100% of the time.
I have seen nothing about the fan speed -- but on the iMac Pro it is very very laid back about engaging fans until it is nearing the peak... (94C). This is something Apple would do... the question is did they and did they go to far.As in running the fans at higher speeds? You mean it doesn't do that now?
Isn't the workload in that test 100% ?no.
the original video has 2017 quadcore and it outperforms the i9 due to throttling.
Are you not getting this? It tells you at that moment. My point is, unless you have reporting that tells you what % you are using for the entire time you're on the computer, this kind of nonsense is irrelevant.I'm not even trying to be smart here. But I appreciate the compliment.
You should do more with your computer(s) i.e. look at Activity Monitor / Task Manager / "top" when you're running apps. The monitor literally tells you how many cores you have running and what % they are running.
His screen name essentially says it all.You called a guy who owns an iPhone X and says he “likes” Apple “anti-Apple” because he wrote something about his experience—and documented it with data—that doesn’t support your blind belief that Apple can do no wrong.

Talk about living in a bubble!
I don't think we've established that it doesn't.The top of the line 2018 machine should have better performance than the top of the line 2017 machine for typical “pro” jobs. Not that hard to define the problem here.
Porsche is German, which literally has the best engineering of any car in the world. I was hoping no one would be smart enough to reference Porsche, but those things are tanks.But if you buy a real car, say a Porsche 911 Turbo S, you can launch it 50 times in a row, with no overheating, no limp mode engaged, no degradation of performance. I worked for Porsche for 6 years, and while I admit to being bias towards them, they back up their engineering by delivering consistently high performing, highly reliable cars (check JD Power and Consumer Reports for the last several years).
Maybe it’s time Apple involve Porsche Design and Engineering over.![]()
What you're saying is Apple has set the upper limit on fan speed to be insufficient to provide the necessary, assuming it's capable of doing so, cooling capacity under heavy load?I have seen nothing about the fan speed -- but on the iMac Pro it is very very laid back about engaging fans until it is nearing the peak... (94C). This is something Apple would do... the question is did they and did they go to far.
Not sure what you mean by this? Apple give you a no quibble 14 day return period in the UK (in practice up to 28 days).
Why not test the i9 out with your RAW processing jobs and let us know how you got on? The would be a good real-world test.
I am saying there are possibilities... but since I don't have one and cannot test the hardware to see if the fan has more room. They did do some slight throttling on the iMac Pro early on while the fans were still so quiet as to not be audible.... i.e. they had lots of room to power up.What you're saying is Apple has set the upper limit on fan speed to be insufficient to provide the necessary, assuming it's capable of doing so, cooling capacity under heavy load?
Not at all surprised. This isn’t just Apple. The entire 8th gen hex and quad mobile line from Intel is fraud, in my humble opinion. There isn’t a laptop on the market that can sustain the turbo clock speeds, from the 8750H all the way down to 8250U. Razer, Dell, Asus, Lenovo, MSI all suffer from thermal and power limits.
This wasn’t the case for 7th gen. My old Blade with the 7700HQ could sustain its turbo clocks on all 4 cores during Prime 95.
My understanding is that the no quibble 14 day return is as per UK Consumer Rights Act 2015, and refers to unopened and unused products. In other words, unless the machine was not as described, or was faulty, Apple has no obligation (or promise) to provide you with a full refund.

Not really.Evidently more so than you do.
