Apple Expands High Power Mode to MacBook Pro and Mac Mini Models With M4 Pro Chip

Wow that's a throwback to the 90', I'd always wonder what does the TURBO button do? The tot of having force induction on the computer is kinda...
Please provide proof that giving the consumer the ability to clock an SOC higher but still within its manufacturer spec “never ends well”.
The "turbo" mode might be more useful in a warmer room. It's hard to test it in November, at least here. In the summer I let the house get up to 80 F. Now it's 67.
Some DOS programs, mostly a few games, implemented a wait loop based on the MHz of the CPU. When CPU speeds increased it would cause these games to run too fast.
Lots of stupid here, to be sure, but not in Apple's nomenclature.About Power Modes on your Mac - Apple Support
Power Modes allow you to tailor your Mac's performance to your workload.support.apple.com
This high power mode only control the fan speed based on the temperature, nothing else. Yes, you might be shocked but that's an official info from Apple themselves. Calling this high power mode is a joke itself. If it's really a high power mode, then they supposed to support overclocking mode by consuming more power.
Such a stupid way to branding the fan speed control as high power mode, lol.
Fan speed and clocks are intrinsically bound. You can't separate one from the other. What this does is change the rules about how fast the fans run, and perhaps the duration of such. This means that the M4 can run for longer at higher speeds before shifting to slower speeds to prevent overheating. (What people call "throttling", though that's an ill-defined word of poor utility.)
This mode is explicitly about allowing longer-term operation at high clocks. It is not, nor does it claim to be, a way to increase the max clock speed. You *want* it to be about "overclocking" (another ill-defined word, at least in this context), but you are not the arbiter of meaning. You don't get to declare that that's what "high performance mode" is all about. Of course you can always start your own company, sell your own computers, and decide how to talk about them. Go right ahead.
For high performance tasks, it does not change the fact that the fan will spin faster. Besides, Apple Silicon chip can NOT be overclocked so it's totally pointless to have a high power mode.
It may be helpful to engage your brain before posting.
For high performance tasks, the fan *may* spin faster. That's the whole point of high-perf mode. In other news, the sun rises in the east.
As for "overclocked", that word is ill-defined and not useful for this discussion. What does matter is that h-p mode will allow the chip to run at higher clocks for longer, completing CPU- or GPU-bound tasks faster. Few people not running benchmarks will ever need that, but for those who do, it's very helpful.
Then you never used PC after all which is totally normal for a long time. Just spin faster? Is it a joke? Like I said, it only controls the fan speed, nothing more. And yet, they are calling it, a high performance mode. Since the fan speed is bound with the temperature, what's up with adding the high performance mode for when it's already normal to spin faster on high temperature?
Another Apple logic?
You know, I read this three times and I have no idea what you think you're saying. It's just nonsense.
High performance mode is not about faster instantaneous performance. That is, it's not about improving the result of a one-second benchmark. It's about allowing the machine to maintain performance for longer without reducing clocks, and reducing clocks less when they are reduced. That makes long jobs complete faster. Thus, it's higher performance integrated over time.
Since the M4 is the fastest CPU core on the planet, I have no problem with Apple just saying "high performance".
As for using PCs... I own racks full of servers, as well as a few random towers. And I have owned literally thousands of x86 machines over the last ~40 years. The vast majority were rackmounts, quite a few were blades, some were towers/desktops. In recent years we'd mostly buy SuperMicro servers, but in years past we built hundreds of servers from parts. Occasionally we'll still throw something together by hand, if it's warranted. So what?
You literally explained how the cooling works and that's what fan speed supposed to control. You said the fan speed is bound by the temperature and yet you are explaining the same thing over and over again. What's so special about this high power mode compared to how fans normally works. If sustaining the performance at a long term is a problem, then let the fan controls the speed based on the temperature which has been normal for several decades and yet, Apple is marketing as if it's totally new.
Seriously, since the high power mode only controls the fan speed, it's already pointless to cover up Apple's branding.
My guess is your whine is off base. Why do you assume that fan operation is simplistically linear to temperature? Why should Apple not create a different fan curve (H-P mode) specifically for sustained heavy workloads?
Note also that high power mode is designed for sustained heavy workloads whereas benchmarks are typically brief, e.g. 5 minutes.

Again, your words literally have no meaning. It's like a monkey typing on a typewriter. "Cover up Apple's branding"??What???
If it will help you to understand... when you see "high performance mode", think "better sustained performance mode". It's really that simple.
Or, perhaps even better, think of it as: "I would prefer better sustained performance at the cost of my fans ramping up RPMs more aggressively".
For most people, there's no need for that, since the default sustained performance is already amazing.
In the G4 and G5 days, that was a big difference. Use it on my iMac G5 and the PowerBook G4. I always used Better Performance when using them as my main machine since the Mac felt faster and every MHz made such a difference back then. But today I use the "Lower Performance" mode for the G5 iMac so nothing overheats or is overtaxed for no reason.Old timers may remember the "Better Performance" and "Better Conservation" options in the Control Strip.
Time is a flat circle.
When Apple moved to Intel, they got rid of being able to select those. Now that Apple is making their own chips again, they are bring the feature back. I love how they are reintroducing these old features again.
Edited: for clarity.

But Apple never used a Turbo button. That was a PC thing and why people turned that off, I have no idea, since every PC I saw and used, with that feature, ran with it on all the time.Now apple it would have been your chance to reintroduce the TURBO button
Why would you think that? They did not. Basically all chips from all vendors can run anywhere on a fairly large performance/power curve. That definitely includes Apple, Intel, and AMD.
Whether your OS exposes that functionality is a different story.
intel did not "get rid of" anything
apple chose not to allow the user to tune intel chips inside their macs
that was apples decision, not Intels
@Confused-User and @nathansz, that is actually what I meant by that statement. When Apple moved to Intel that all went away. I wasn't saying that the Intel chips didn't have the ability or anything like that. I was talking strictly from a Mac/Apple perspective and thought that would be understood. Sorry for the confusion.
