What if Apple does not release a new MBP at WWDC in June?

If we Undervolt the cpu, why do we pay more to get a high specs cpu?! Please educate mez
You can slow it down for certain operations/apps/activities, its again to throttling, but instead of waiting for the CPU to hit 100c you slow it down a bit so that it doesn't go that far. Many times undervolting will slow it down just enough to allow the fans/heat pipes to keep up with the heat but not drastically impact performance (like throttling does)
Not underclock, undervolt....
By undervolting, the performances increase but only when both CPU and GPU are stressed since, when both are full load, temperatures are so high that CPU can not reach it's max turbo speed...
Obvously this happen only in thin laptops where you can not have a cooling system with a lot thermal headroom..
By undervolting, CPU temperatures decrease so the CPU can reach it's full potential (i.e. Max Turbo speed)
Agree I'd be inclined to walkaway, I bought my new Asus S7BS750 directly from a local ROG Store, the guy's there know me. They also know that I'm not looking at a notebook to game on, more a high performance notebook for work purpose. The guy's at ROG were great having no issue with me looking at all the inner details, even testing the demo model
Although the S7BS8750 is a regional variant, I was immediately impressed by it's performance and thermal envelope, nor has it disappointed...

By undervolting you will not slow it down....on the contrary...by producing less heat cpu speed will increase because all cores can reach their full turbo speed...
Undervolting is not underclocking....
No that's inaccurate; Undervolting the CPU Core & Cache, some instance iGPU both current and power consumption is also relationally reduced (Windows). This allows the CPU to run cooler taking longer to reach T-junction, often with notebooks this allows for more performance; reaching full Turbo, with longer boost periods, reducing tripping power limits set in the system (PL-1 & PL-2)
If you want to limit performance for thermal reasons either globally or by the use of profiles, you would look to reduce the Turbo Ratios Limits, which too can help to improve performance in notebooks that have inadequate cooling systems.
It's not done at source by the OEM's as by default every CPU is unique, having it's own tolerance to core voltage etc. Aside the potential performance increase, both battery life and fan noise can also benefit from undervolting.
By undervolting one can literally eliminate throttling and certainly reduce CPU temperature significantly, easily 10C - 15C potentially more.

hm, i did not od that. I played overwatch for about 10 minutes and I didn't hear anything. At the same time, there were a lot of people in the store.
I might join ya.. That ship has sailed anyway
In some ways, we gotta feel 'cheated'
With voltages getting lower and more cores added over time its a constant race to keep down that temp for each core to hand more of a given task with more getting up to max.
lower voltage would be better on CPU, but at some stage you gotta add more cores

I don't feel like reading through 22 pages to find out if Apple is releasing a 2018 MBP. I have an opportunity to go and buy a 13" MBP at the Apple Store this Saturday, June 16, 2018, "tax-free" plus a 6% company discount. Should I move forward with this purchase? How much longer is the wait for the 2018 MBP?
Why doesn't Apple make an announcement on the keyboard issue and let customers know what they are going to do with it and the due date? Apple is way behind other manufacturers in releasing laptops with current technologies. They don't need to keep secret on the road map.
Yeah they really don’t need to keep it a secret. It’s kind of stupid anyway. We want you to buy our products but we won’t tell you when we are releasing them.
On the other hand, their big cash cow iPhone, the one bringing in all the money, is on a regular schedule and we know when it’ll be released. You’d think they’d get the hint.
Anyway, I actually might break down and pick up a TB MBP 13 tomorrow. Need one desperately and my MacBook 12 keyboard is fine so I guess I’ll take the risk.

Simple Osborne effect
Apple makes an announcement that they'll be making a stronger keyboard - boom that will cost them millions upon millions in sales because they just admitted that the keyboard is faulty. With three lawsuits already in the queue that will cost them a lot in damages.
Second issue, is that people will largely stop buying the MBPs and given that this issue is 2 years old, apple just blew a lot of brand good will and integrity. People may have a hard time trusting them and that also will affect sales. Would people trust apple in that they really did fix the keyboard. That's an issue now but by admitting it, that issue expands expoentially.
If anything apple will market the MBP as better, and more improved without giving any lip service to the issues with the keyboard.

Excellent post maflynn. Making decisions for a multi-billion corporation is much more difficult than what an average forum member here things. Companies and careers have been ruined because people have been too naive or too open. It is an unfortunate fact of business and politics...
Still, it wouldn't hurt Apple to more transparent about certain things I hope they can figure out a way to do it.

thanks, I'll produce a good post once in a blue moon
A repair program tends to offer the transparency and provides apple with a positive spin, i.e., see we're doing everything to ensure the customers are happy.
Agree with all of this.
In the interest of intellectual discussion then, don’t you think Apple should randomise the launch window of their main cash cow, the iPhone, as well?
This will prevent low sales in July and August as consumers stop buying the current models and wait for the new ones to be announced in September.
If they put it on the same secretive schedule like the Mac, then people won’t know when to stop buying, hence maximising current model sales. For example, if I didn’t know a new iPhone is coming in September, I may upgrade
my 7 right now which has been overdue for an upgrade for a while.
Or are they too stupid to apply their sales technique to all of their product lines? (And now someone will respond to me and tell me no they’re not stupid as the iPhone brings in the most amount of money so clearly Apple know what they’re doing and they’re the most profitable company etc. - which will bring me back to my original point)
They were moving to spread out product launches to have a more consistent income flow, but I think external circumstances have disrupted that from time to time. While they want to spread out new products they still want to avoid times of the year where people are not intersted in buying products. For instance July tends to be rather dead, not just for apple but for many retailers. People are not looking to buy computers, phones or tablets in July. Its just a fact of life. Its like trying to market a snow mobile in June, or water skies in January. Most people are not interested in those products during those months.
I don’t think it’s about randomizing product launches or secretive schedules. Apple has much more control over iPhone components than over Mac, where it has to depend on Intel and AMD. Not long time ago, when Intel released CPUs in regular intervals, Apples updates to macs were just as regular: two times per year. Intel is all over the place now, and is seems like there are some problems with volume availability of Coffee Lake mobile CPUs. Same goes for the GPU...
This is exactly why I'm so hesitant to buy. I guess you answered my question on the keyboard issue. I'll postpone my purchase and hold off even longer than anticipated.

Maybe, Apple should release quality products (or fix any issues that surface right away) so people like me wouldn't have to wait for the new and improved and buy what's available now.
Is it normal that playing 4K videos triggers noisy fan? That is what people at MS Store told me about the Razer Blade 15 2018. As mentioned, I asked the sales to show it to me but the manager refused to do so. (They put some kind of restrictions of all laptops in the showroom to prevent people from using yoututbe.) When I had the MBP 13" 2017 TB version, it was silent when I played Youtube 4K videos.
Video stream will be decoded in hardware, so it's not going to get hot simple as that...
