I'm not well versed in CPU design; how does a 3.1Ghz peak clock A14X outperform a 4.8GHz peak clock i9 [1]? The only thing that immediately comes to mind is a massive hypothetical instructions-per-clock advantage.

The time it takes to execute an x86 instruction is not constant and the amount of concurrently executing instructions (pipelining) is not the same between these two CPUs. Also, power management works every different in arm so it has a lot of boosting head room.

Not too familiar with cpus but if it's known that arm outperforms x86 while also being more power efficient, why aren't everyone using it? Why did it take until now for a major computer manufacturer to switch?

Apple's IPC advantage isn't hypothetical; it's been measured (mostly by AnandTech) for years.

That being said, I'm a little skeptical of a 4 big + 4 little A14X beating Intel's 8 big cores.

Geekbench is a scam

Note that it says it outperformed an "Core i9 MacBook Pro" not a "Core i9" so depends on throttling due to heat. It's quite easy to believe the A14X is more efficient and can win in those conditions.

It's not always just instructions-per-clock, sometimes it's also data-per-clock. Specifically, the Apple Neural Engine in the Bionic chips can perform some vector computations faster than anything in either the CPU or GPU of any Intel Mac.

Apple should of made the iPhone dockable years ago. They could own the PC market right now. There’s no reason I should have a separate laptop or desktop with an iPhone 11 in my hand.

whats the advantage? A tad cheaper?

I gladly prefer to be able to use my phone and laptop simultaneously for different tasks and will pay that premium.

Don't know why you got downvoted. I makes a lot of sense to tightly integrate desktop and phone (answer and make calls from the desktop, continue browsing on any other device) but it makes little sense to demand the phone to also be a good desktop, as those are two conflicting engineering goals.

trixie_5• 6 years ago

Depends how it is 'attached'. If it were wirelessly attached you could use both. Similar to how wireless CarPlay works.

I believe HP tried a dockable Windows phone a few years ago. Looked neat.

It's a pity that Windows phone failed, it was pretty good and we could use a third choice.

Edit: 2016 HP Elite X3, e.g. https://www.cnet.com/reviews/hp-elite-x3-preview/

Asus tried too. Many companies tried to make MP3 players before Apple as well. The point is execution, and I believe it is a slam dunk for Apple. Majorly upsetting the balance of PC ownership.

rbanffy6• 6 years ago

You will still want a keyboard, trackpad, and at least one screen. At that point, you might as well add a CPU and some memory, flash and battery and have a full laptop that can sync with (icloud does an excellent job at that) and charge your phone. Many companies tried dockable phones and it never worked well. The cost of a dock is more or less the same as the cost of a desktop as smart or smarter than a smartphone.

trixie_5• 6 years ago

Other companies tried mp3 players, and then there was apple. A cost of a desktop dock would be nothing compared to the cost of a tower. The mouse/keyboard/monitor you'd have to buy either way.

How it compares to normal i9 device. Linus took apart a macbook air and the cooling was so bad that it may be the reason the i9 cooling so badly designed. It may be badly designed on purpose to show that the performance of arm chips in macbooks is comparable to an i9 without cooling https://youtube.com/watch?v=MlOPPuNv4Ec

The i9 is not in an Macbook air. It's in a Macbook pro 16 inch which has a completely different design. But you are right that all ultra mobile laptops on the market have way too shitty cooling. You could easily get an additional 10% of performance if the OEM would stop the insane thinness war.

Interestingly the latest MacBook Pro did get thicker than its predecessor. Not a lot but perhaps they have got to the point where they are thin enough.
