So much irrationality, such ignorance.
I did not write this for the MacBook line, the same thing applies to all laptops and yes phones as well, I'm not an Apple fanboy no thank you.

First of all, since I am assuming by "throttling" we mean a reduction in clock speed (technically the term refers to both reductions and increases), we need to ask ourselves an obvious question. What is the reference point from which we determine that the clock speed has been decreased?

Well the "base frequency" of course, which in the case of the i7-8559U is at 2.7 GHz. Which the 13-in MacBook Pro can sustain at. What seems to be the problem here?
Even with the notorious 15" and i9-8950HK, which has a base frequency of 2.9 GHz, the 15" MacBook Pro again, can sustain that frequency indefinitely at regular room temperature.

So it would seem that by definition, we have no reduction in clock speed, we have no "throttling" at least not on the 2018 MacBook Pro line, period.
========================================================

Obviously, for the hater to even have a case at "throttling" accusations, they would have to define the base frequency faster than the "base frequency" Intel provides, which makes no sense. These people would have you believe that these processors are "supposed" to be running at their maximum turbo boost frequency, so that they can call it "throttling" when the processors actually runs at its "base frequency" as defined by Intel.

Intel® Turbo Boost Technology 2.01 accelerates processor and graphics performance for peak loads, automatically allowing processor cores to run faster than the rated operating frequency if they’re operating below power, current, and temperature specification limits.

If I'm reading this right, it sounds like for the i9-8950HK, anything faster than 2.9Ghz is "faster" than what it is supposed to run at. And this should only happen if the processor isn't at maximum heat or power. NOBODY EVER CLAIMED THAT THIS CAN HAPPEN CONSTANTLY.

So again there is no "throttling" what so ever, not the MBP15, not the XPS15, not the Razer Blade. These processors are running just as fast if not faster than their "rated operating frequency".
========================================================

Yes, as a matter of fact, if you put a water block on an i9-8950HK connected to a 240mm rad, with beefed up power delivery, you'll be able to run it at 4.8Ghz constantly. However it's just a twisted way of thinking and an absurd argument. Why even stop at 4.8Ghz? Why not put it under a copper tube filled with LN2 and go for 5.8Ghz? And then you can claim that any computer not running the i9 at 5.8 Ghz is therefore "throttling". You get to feel superior and look down on even more people! I'm guessing that didn't happen because most gamer nerds can't afford LN2 overclocking themselves.

There is a smooth and continuous function that describes the relationship between power draw and clock speed for every individual chip. There are no points on the curve that is special compared to any other point. When Intel says that the i7-8559U is 28W@2.7Ghz, that's just an arbitrary point on the curve. There is nothing preventing you from putting the i7-8559U in a 15W thermal environment, or a 65W power environment. So there isn't a frequency where the processor is "supposed" to run at in the first place. Just like there isn't a speed at which your car is "supposed" to run at. You simply drive faster or slower as the situation demands it.

(FYI There are different chips for different power levels because of factors like PCIE lanes, instruction sets and cache sizes that can be optimized for a specific power range. The execution cores are essentially the same.)
========================================================

Also if you just imagine yourself designing a laptop yourself you'll understand that these actual laptops are completely rational designs. And that irrational loud gaming nerds on the internet are being ridiculous with what they are asking for.

Say you are in charge for a new 15" laptop. The marketing research guys have told you that the company should make a laptop that is no thicker than 18mm and no heavier than 2kg. If you ignore that and make a 5kg brick then you'll be fired because nobody would buy such a heavy laptop.

So you ask the engineering department ok how much cooling can we fit in that case while still having enough space for 7hr honest battery life? Your guys tell you that they can cool 60W without blowing out ear drums.

Now you can pick your processors, you have two choices:
Processor A run at a constant rock solid 3.2 Ghz with all 6 cores with a TDP of 60W
Processor B run can also run at 3.2Ghz with all 6 cores at 60W power, but can spike up to 4.8Ghz if temperature isn't already at maximum.

Would you be an idiot and pick processor A just so that you can avoid "throttling"
Or would you be reasonable and pick processor B? Because you know, B is obviously better in every way possible, except some idiots on the internet will accuse it of "throttling" when it clocks down from 4.8Ghz to 3.2 after 3 seconds of maximum load. Where as A just runs at 3.2 all the time.
========================================================

Yes ok, if only they made the laptop thicker and heavier, it would have better cooling and sustain higher clock speeds. But guess what else has that? a desktop computer. Why make a laptop so large and heavy that it might as well be a desktop? If weight doesn't matter to you because you never move your laptop, just get a desktop!

The higher end processors are in fact cooler than the lower end ones, contrary to ignorant speculations. Intel's "base frequency" is rated for the TDP of that processor model. So for 45W processors, if one is rated at 2.9Ghz and another at 2.2Ghz, the former generates less heat than the latter when run at equal frequencies.

So there is nothing more ridiculously stupid than claiming that an i9 will be slower than an i7 due to throttling. There is no throttling, and the i9 has been shown to be always after under all circumstances.

You're missing the point - the issue is not about throttling but how it is implemented. And it is mostly already fixed by Apple in MacOS at least. If you want to have fun - boot Windows on your Mac and enjoy the ride, the clocks fluctuating between 1.1 and 3.8 GHz at steady load. I can program control scheme for a 600MW coal fired boiler keeping steam temperatures within 2 degrees of the setpoint that has literally hundreds of disturbances, and it blows my mind that Intel can't implement a robust algorithm that depends only on one.
 
The thermal management has to be addressed.

Bootcamp is horrid!

There has always been a lack of thermal management when running Bootcamp. However, it has never been to the point of thermal throttling out of the gate and causing such erratic performance.

Bootcamp will be pushed off and dismissed by many with the following statement. "If you want to run Windows, buy a PC"

To my response is, If your going to have a feature called Bootcamp, make sure the feature works correctly.
 
I commend the effort. However I think it's far too long for certain people to actually read through sadly. I don't think people actually want to understand, it's must easier to jump on a hate train to boom town than it is to hop onto the nerd express to virginville after all...

People are awfully confused, and there's always some particular that dominates and people jump on, with absolutely every single launch of a new product. Conspiracy theories will always pop up because they're interesting, problem is when people claim fact and push views based on misguided teachings.

I still see people looking into things such as "My CPU is only running at 1.2Ghz?!", and not understanding that this has always happened, why would a device being powered by a battery waste twice the power when you're only browsing Netflix?

Anyway, thank you for taking the time and I hope it helps some people understand and calm down a little. :(

Wait....

Please tell us the last time Apple launched a laptop with such blatant throttling issues? (In my memory, we would have to call back to the original MacBook Air.)

Yes, they addressed and patched the system under OSX. This did not address the system/device as a whole.

Additionally, Apple has the Bridge OS KP mess on their hands. This is the equivalent to a windows BSOD. Seriously?! This has been ongoing since the release of the iMac Pro.

Their fix today did NOT fix the issues of Bridge OS and the speaker issues on 2018 MBP's.

I'm not hating, just completely in disbelief that Apple, the one that had things ironed out before release company, has become this dismissive and arrogant. (Another OEM)

I don't understand why we are being called Haters for expecting the product Apple has traditionally delivered and stability they have been know for over the years.

We, the haters have been conditioned, some over 20 years to expect this type of JV League behavior to be left to Window's OEM's. Those that slap together and churn out a new product every other month without support or care.

Let not forget that Apple has had PLENTY of time to work on software since they had not upgraded these machines for longer than most. What on earth were they doing with their development time? Was the focus plainly on moving from the old campus to the spaceship?

I'm one of the confused. I don't understand the need to explain the basic principles of a 14 year old technology on a internet forum frequented by people who know about computers and in vast majority are aware of this revelation. While at the same time completely ignoring the core of the throttling issues experienced at launch of 2018 MBP and still continuing into Bootcamp.

Nobody is talking about that issue, why don't you take that somewhere else.
I'm not saying there is or is not an issue with the T2 or Bridge OS, because it has nothing to do with this post.

Yes that was a problem but that isn't the problem I have in mind because it has been fixed.
I thought that was obvious since I also mention other laptops that did not have this problem and do not run bootcamp.

Intel in their infinite wisdom left throttling to the computer manufacturers to implement, although they (Intel) hold all the keys and data about their silicon that would allow them to implement throttling algorithm on chip, with pinpoint accuracy. There is no denying that at launch Apple screwed up, and i9 was especially affected because of higher allowed clocks. Right now it is a non-issue, on Bootcamp I'm just running power settings at 98%, that limits the clock to 2.1 in my case and allows enough headroom for the 555x to run freely for games, which is the only thing I'm using Windows for now. But since Apple never provided anything that would use SpeedStep in some sensible manner in bootcamp I'm forced to take care of this myself, although a proper Apple implementation would be far better.

And really - I seriously doubt there is a lot of people who don't understand what throttling is and how it works. Or at least, I hope so.

I spend 12 minutes of my life I'm never going to get back. Thank you. BTW - your link was pointing to a different video which I closed after the revelations about 8600GT. I was using my rework station to revive dead Asus G1S back in the days, and no - it wasn't Apple fault. Actually Apple behaved better than all the others during this particular fiasco. I remember thinking I should have bought a Macbook instead of Windows box. Funny thing - after replacing the board with 9500GT the bloody laptop refuses to die and is still in use by my 4 year old. And more funny thing - when I was showing my collection of vintage computers to some of my coworkers, making the same remarks about the Santa Rosa CPU, one of them was like "I'm still using core 2 duo work issued laptop". In 2018.

But that Linus guy, I'm assuming that was the video you were referring to, on top of the thread, I don't even know what to think about it, 1 million views, I guess it is the sign of the times we live in. Jumping to a conclusion without asking simple WHY? Again the name reminiscent of Linus Torvalds, which makes it look legitimate, but just simply is not. "Your conclusions were all wrong, Ryan..."

He's a tech journalist, 'tech' being the keyword... Known for simply parroting company claims without doing any journalism into whether these claims are valid. Tech journalists are great sources of misinformation :)

Your delusional.

There is a throttling issue.

In your frame of mind I guess the software patch Apple sent down to put a bandage on OSX was not needed. Why bother right because at some point it’s gonna throttle...

Give me a break!

The T2 and Sound issues are relevant because you can just add that to the pile of things that need to be addressed.

Todays patch did nothing but buy them more time. Not fixed....

I’m not going to argue or belabor this point.

The more you try and dismiss these issues, the less credibility your case become.

This is not Intels fault. Please don’t even try that one.
 
Where is it? show me! it runs above the "base frequency" as advertised by Intel and Apple.

I have a better idea.

Why don't YOU install Windows 10 on your machine and run Cinebench a few time and report back?

This way you get an accurate feel and results so they cant be misconstrued.

Also, try playing a game for about five minutes and enjoy the fame spikes caused by unnecessary power limit throttling forcing the clocks to become erratic and the chip to heat up beyond thermal limits.

Sound familiar?

It acts just like OSX did pre-patch.
Don't give me that garbage about (Base Clocks)

If Lenovo, Dell, Razer and others can create laptops that continually boost well beyond their base clocks for extended periods of time, in a smaller package I might add, then this lame duck excuse is only more finger pointing.

You don't HONESTLY believe that base clocks should be the performance level garnered and be appropriate when others OEM's products boost all day long? Come on man.... I don't believe that one bit.

If you can solve this for all of us, we would greatly appreciate it.

This post isn't about bootcamp, or even the MacBook. it's about laptop thermal design.
Just because there are frame spikes doesn't mean there is throttling.
 
There is a throttling issue.

What throttling issue are you talking about? All test I've ever seen (or run myself) show that these CPUs are comfortably running within their specs and within the frequency range they should run. Haven't seen a single case of evidence to the contrary yet.

In your frame of mind I guess the software patch Apple sent down to put a bandage on OSX was not needed. Why bother right because at some point it’s gonna throttle...

What are you even talking about? At launch, there was a power management firmware bug that could cause erratic performance under certain circumstances. Apple has long fixed it. Is that your "throttling issue"?
.

Who is talking about faults? The CPUs have certain specs and the MBP perfectly adheres to those. If Intel is to "blame" for something, that would be crappy marketing and arguably customer-hostile practices (like repackaging the same CPU for the forth years and selling it under a new name).

IF cpu and gpu are both loaded for extended period the cpu frequency will drop below 'base'.
 
It isn't a conspiracy, but as you said, unrealistic expectations.

There are some who come from desktops or huge laptops which managed to keep the turbo boosted speeds indefinitely and as you said, that is unreasonable to expect in these machines.

I don't think there is a lot of people who think like this - and to be fair the main issue came about because the throttle issue resulted in the MacBook's going below the base clock (which has now been fixed). Truthfully, I think you are talking about a non-issue as I rarely have seen complaints about throttling over the years (and the recent spike as stated earlier was due to a VRM issue). Even on Notebookreview.com on the gaming notebook subforums, it is pretty much accepted that the laptops won't hold max clock speed all the time.

What is a valid cricitism (this isn't Apple related, but I am talking laptops in general including Windows) is comparing average frequency when stressed. Some laptops can manage say the max turbo boost for 1-2 seconds before going down, while another laptop may be able to handle it for a minute. Some manufactuers can greatly improve how much CPU they utilise by quality cooling solutions/heatsinks (it doesn't have to become a 5kg behemoth). For example, an i5 XPS 13 has managed to out perform many Window laptops on the i7, just because it offered a better cooling solution (without being larger). Even in the gaming community, some laptops downclock a lot more than others particularly on the dGPU and the main culprit wasn't because the laptop isn't a 5KG behemoth, but the company made poor design decisions evidenced by the fact that laptops the same size or smaller managed to beat them at it with the same components.

If this is true, then that is unfortunate. But I am sure Apple are catering to the 98% of scenario's rather than the 2%, which understandably may sit sourly in people's mouth given these are "Pro" machines and not Netbooks to watch Youtube and browse Facebook.

I take it your running strictly OSX.

Throttling and pre-patch behavior still exists when running Bootcamp. - That's what i'm talkin' bout.

This generations 28w 4c chip inside the 13" MBP and or the 45w 6c have no resemblance to outgoing chips from last year. Intel is not perfect, but this was not their issue.

Listen, I understand that Boots clocks are not indefinite and need to scale back. However, its not unrealistic to expect level management to allow headroom for the processor to breath.

I am happy that you are pleased with your machines and their performance.

Really? Coffee Lake is just Kaby Lake with two cores added. All you get more cores and slightly increased speed. And now they have released Aber Lake/Whiskey Lake, which is basically just overclocked Kaby Lake...

Yes really!

Adding 2 cores to a package is just rebranding in your eyes?

I would expect the opposite stance with the 2018 MBP if its that hard to impress you.

Whiskey Lake is indeed a refresh, the first since the release of a 15w 4c CPU. (One that matches a 7700hq when tuned right) That's pretty darn impressive.

Very much true. And also the case for any other laptop in the same weight/size category. Dell XPS designer for instance has publicly admitted that this is the case.

Personally, what I would really like to see is a combined CPU/GPU package with dynamic power management, just as the G class chips from Intel. Having 80W combined is so much more flexible than separate 45W for the CPU and 35W for the GPU. Need CPU power? Let the CPU run at 70Watts sustained and really crank those clocks up. Working with videos or gaming? Get the CPU clocks down and send more power to the GPU, etc. etc.

I don't see much of a difference. Its a cheap "way out" and a way to sell stuff without any real under the hood improvements.

Performance increase are adequate for my purpose, but I am unhappy with the tech stagnation Intel has been experiencing. Best to stay realistic. We have the state of affairs we have and I think that MBP is an excellent computer considering the limitations of components it has to rely on.

And what are 15w 4c CPUs? Nothing more but down clocked Skylake/Kaby lake chips (the same as the 7700hq you mention) that just have been optimised to the max on both process efficiency and power curve. Again, no real progress here. Same architecture, just minor efficiency improvements and just rebalanced clocks. Hint: when it matches a 7700hq, it also consumes nearly as much power for a short period of time. Before it plummets down to meet its 15W limit.

I understand that you may not see that much of a difference, but it significantly helps those with workloads requiring the cores.

Come on now... taking the architecture from 45w to 15w and blowing the door open for ultra portables to harness the power is more than a rebadge.

Hopefully I can have a 7980XE 15w chip next year :) (Its a joke)

I thought the G chips were interesting too - however the two laptops using them at present (XPS 15 2-1 and the Spectre x360) weren't too convincing.

The XPS 9575 was comparable in performance to the 7th gen CPU combined with a GTX 1050.

The HP Spectre x360 seemed to have regressed as per the following excerpt from Notebookcheck.net:

Dig deeper into the performance of the Kaby Lake-G Spectre and the system begins to disappoint when compared to the Kaby Lake-R configuration. On paper, the Core i7-8705G and Radeon RX Vega M GL should be significantly faster than the i7-8550U and GeForce MX150. In practice, however, the Kaby Lake-G SKU suffers from considerable throttling issues that ultimately mitigate much of the performance advantages that the chipset brings to the table. Owners who intend to use the notebook for mostly word processing, streaming, or browsing will not notice the throttling, but running demanding sustained loads like games will bring the system to its knees.

The lower power profiles of the i7-8550U and GeForce MX150 also work in favor of the less expensive Kaby Lake-R configuration. Our Kaby Lake-G unit is generally louder and with a much shorter battery life than the Kaby Lake-R version.

This is their first run at it so it could only improve in the future (hopefully).
