Performance Per Watt matters to Intel except when it doesn't. But really when you have to dissipate so much heat then the chip will be throttled. Apple's ARM chips are only getting started.
Exactly. Apple is not even trying and Intel only just caught up. This year, they will find out that the M2 will set them back another 2 years.
Luckily there will be the new zen 4 apus to wipe the floor with them

I don’t think this is going to happen, but: It would be extremely funny if Apple strapped a heavy copper heatsink and a turbo fan to an M1 and just overclocked the ever-lasting crap out of it. The crazy thing about using a Macbook Pro (with an M1 Pro or M1 Max CPU) is that, in single-threaded performance, it's really no faster than a dippy little Macbook Air. And at the end of the day, single-thread performance is mo…
> in single-threaded performance, it's really no faster than a dippy little Macbook Air. Maybe in terms of raw FLOPS or something, but more importantly it has enormous levels of memory and storage bandwidth, which is what's actually important for most user workloads these days. That's not even accounting for the performance of the GPU cores which can be used for a ton of multimedia workloads.
I've heard this tossed around a lot, but is there any evidence that it's actually true? I struggle to imagine a regular workload that benefits from 32gbps of bandwidth, much less a scenario where the average layman could saturate a 200gbps or 400gbps bus.
3.5%-5% increase in performance at more than double the wattage, for a chip that is not in consumers hands against a chip that basically hasn't changed and was released 14 months ago~ This is not the victory that the title implies. It's also a _little_ bit funny that the i9 laptop was double the price, given people usually rant loudly about how expensive Apple computers are.
Do that, same wattage, less than twice the price, twice the performance. Now what, Intel?

Google propogation delay, your pipeline's length and delay of devices within that pipe determine the max frequency your circuit can run at (a very high level overview).
How is pipeline length related to max frequency?

Out of curiosity what jobs need a good CPU but also can't take advantage of a good GPU? It seems like most of the high performance numerical computing software today is GPU-accelerated. If performance for your job is super important, why isn't your software GPU-accelerated? I might just be naive but it's honestly hard for me to imagine why anybody would need a good CPU and not also want a good GPU.
Since this is HN... compiling.

Still using a Note 8. This phone is awesome. I forget how many years... I would be OK with my M1 Air performing in a similar way.
This is a decent example of what folks are talking about in terms of supported lifespan. Your Note 8 was EOL'd in October 2021. It came out in September of 2017. That's four years of support. My iPhone came out around the same time and Apple is planning to support devices several generations older than mine with iOS 16...
Just saying.
Otherwise, yeah! My wife has an older iPhone still nicely supported, and older than my Note.
My last Mac was a 2012 i7. I used it 6, 7 years? It is still useful, but got coke on keyboard! I fixed it myself last time. Not doing it again.

Sadly, I don't think the M1 family will clock any higher than it's already going. The rumored M1 Max Duo and M1 Max Quadro will have more cores but they'll still trail Intel in single-thread performance (although not enough for most people to notice).
4-die Apple Silicon machines will surely come, but not with the M1 Max die. It'll be a new design.

Overclocking isn't just limited by heat dissipation, and dealing with the additional heat generation is one of the easier issues to overcome. Much more limiting is the fact that the electronic components in the hardware (everything from RAM to the more "integrated" components on the PCBs) have certain amounts of time which they need to take in order to tie voltages high or low, to either read or output a bit. This am…
AMD chips are doing similar clocks to Intel on TSMC N7, so Apple could (but won't) have a chip running way higher than the clocks they are currently shipping with.
Also, it's kinda inaccurate to imply any overclocked setup will crash, there's plenty of room unless they come turned up to the max from stock like the 12900k.
