It will come back when Apple switches to using their own ARM-based processors. They are perfectly suited to run in an fanless system like the Macbook and far are more powerful than anything Intel has at that TDP.

and who is going to buy that arm-based laptop?

Apple doesn't compete with Dell...

and in a reality, apple really doesnt compete with anyone.

Similar set of folks that are buying Lenovo , Samsung , ASUS , and HP ones.

And the 8cx ones due out the later in 2019

https://www.anandtech.com/show/1442...5g-laptop-a-lenovo-with-qualcomms-8cx-and-x55

Similarly a C8x is probably on track in several months into the future

https://9to5google.com/2019/06/28/google-second-snapdragon-chromebook-trogdor/

( PC vendors will sell both Windows and ChromeOS variants of same baseline..... just like several previous iterations of designs. )



and in a reality, apple really doesnt compete with anyone.

At one point Apple ran a whole ad campaign that was themed "Mac vs PC". The do complete. They don't often let the competition completely dominate the feature list ('more' ports , 'better' Y than system X's ) or get into a "monkey see , monkey do" completely match the features checkboxes contest. Or exactly matching on price war competitions. Are certainly not trying to make everything for everybody ( that isn't a competition at all they even want to remotely engage in. )

But Apple knows they have some general bounds they need to be competitive in the subset of systems they do.


One of the areas that Apple tries repeatedly tried to deliver in is to the "princess and the pea" laptop class with lightest, thinnest Mac laptop but also one of the longest battery life. The MacBook didn't quite work, but they will probably "re-tool" and come back a third time with something in that space. ( The MacBook Air is now in the "affordable" Mac laptop space more so than thinnest. )
 
PCIe on ARM is absolutely possible. For example: https://www.marvell.com/server-processors/thunderx2-arm-processors/

And Thunderbolt is just external PCIe.

Thunderbolt is not "Just" external PCI-e. Wouldn't need a different data transmission protocol if it was just one thing.
Thunderbolt is primarily about transporting a mix of stuff in two directions. It has edge case uses outside of that zone but that is what it is best at.


Such as? AMD doesn’t seem willing to produce useful laptop CPUs.

AMD is willing. It just isn't as high a priority for them, so it is a matter of timing Given the margins are much thinner and their financial book position over the last 3-4 years and current debt level they are probably right in their ordering. And the lower down on the Mac Laptop spectrum you go Apple has their own "iPad Pro" solution they can probably throw into the mix. AMD trying to displace Apple in Apple products where Apple has traction isn't a 'battle' AMD should be looking to fit. They do't have that much excess R&D budget to burn. AMD is already engaged against two ore 'deep pocketed' competitors ( Intel and Nvidia ), they need no fight with a third with an even bigger 'war chest'.

By mid-late 2020 they could have something decent for the top end laptop space. That is where Apple is much weaker. If Intel has blown more deadlines by then Apple may be sufficiently pissed off to jump ship. 'When' Apple wants to switch is a big factor too.

For the 'small' die, laptop chips Intel's 10nm is going to be a bigger stopgap than their 14nm will be in the desktop and up space. In other words, Intel is weaker in the latter so that is where AMD is putting most of their weight. It isn't that AMD doesn't want to do laptop chips. It just doesn't make sense for them to go first there on each new generation for the next several cycles.

Because Intel is synonymous with Windows and, ultimately, Microsoft. Microsoft is seen as the antithesis of Apple, and that extends back to Intel. The two companies collective dominance in computing over the past 40 years raises some very primal emotions in certain users. Apple embracing Intel is seen as both a capitulation to an inferior solution and a step towards the Mac and macOS ultimately disappearing altogether and there being no alternative but Windows or iPadOS, which are both considered completely inferior to macOS. There is also a bit of elitism that surrounded PowerPC as it was seen as a superior RISC-based solution to Intel's crusty old x86 dinosaurs, and by virtue of Apple (Steve Jobs) embracing the dinosaur, something unique and special about the Mac was lost and some users felt they had been turned into the very lemmings that the famous Macintosh "1984" ad rallied against, which came off as a big corporate betrayal by someone they idolized and would never do that to them...but I'm just spitballing here.

Exactly! I think that ultimately, we’ll look back to the Mac using industry standard intel chips as an anomaly in its life.

I suspect that the Mac will still be around in 2030 in some shape or form.

So for 45 years or so, only around 15 of those will the Mac have used non specialised processors.

The Mac using A series chips will really be a return to what makes a Mac, a Mac.
 
I hope they are quick with a retina, silent, LPDDR4 machine using these CPUs.
My Macbook Air 2013 is still going strong and I told myself to wait until I get these specs.
I completely removed all VM's from this machine as it was to CPU intensive and now run Visual Studio Code and Azure Data Studio (~SSMS) for Mac. So no need for VMs or PCs anymore. Just want a better Air or Macbook using Ice Lake to do all my dev work. I should be cheering Microsoft, actually, for these great new tools that can be run on multiple platforms! Thanks!

Woah there buddy! I think we need to clarify a few things....

Apple used pre x86 chips prior to getting in bed with Power (Motorola and IBM) Jobs was not around during that transition, yet prior did use Intel chips unless I’m mistaken.

Intel has been mad trying to court Apple since long before Apple G3 burned their “bunny” lol. Jokes aside yes Intel has been trying to court Apple since the iMac yet never could.

IBM made a fool of Apple and Jobs after their glory of the PowerMac G5 - a glorious feet which with OSX panther launched THE fastest desktop in the world for almost 11 mths and ticked off the competition having to finally come out with one faster and immediately pushing Apple to remove that marketing lol. Still Apple was first with 64bit OS and with 32-bit apps running natively (for consumers; Opteron was first to 64bit in servers yet was junk vs Power CPUs back then).

Something happened after the first year of Power G5 where IBM seems to never care pushing again for desktop or even mobile cpus.

Apple has NO CHOICE but to go with Intel and since NeXT OS was ported to RISC and CISC cpus mostly Intel the rest was history.


Apple has never hated on Intel just loved to crush them in performance, the anti Apple was IBM little did many fans know they where partners with motorla and Apple lol.

I’d love to see AMD cpus in Macs the latest revisions but we’ll see if the future of Apple OS in laptops and desktops is fully mobile as in The Navigator which is body n soul living in iPad Pro with Siri.

Not sure what this is trying to say, but prior to Power, Apple used Motorola chips, and did not use Intel chips.

Is the ARM MacBook ever coming though? It seems like it's been thrown around for 3+ years now, haven't heard anything substantial about it being a reality.

It's coming.

The most recent step happened at WWDC, when Apple revealed new technologies to allow iOS developers to target Macs. Stay tuned to next year's WWDC.
 
Who knows... next year may bring ARM-based Macs! So it would be worth the wait!

Raw clock speed is largely irrelevant in the age of parallel processing.

700MHz x 4 cores = 2.8Mhz effective processing, with LESS HEAT and BETTER BATTERY life.

I'm not an expert, but this is the general idea.

Meh, IPC is up and clock speeds are down so overall this is kind of a wash in the CPU department, but it got a significant boost in the graphics performance.

Given the 3.2Ghz max all core boost (and if OEMs include adequate cooling) this could actually be pretty great for a lot of people. Super long battery life when doing light tasks, and the on demand power for occasional heavy lifting—heavy for the average user.

True... that number looks low. But don't forget the metric "Instructions Per Clock"

My understanding of the theory is... even though it's only going at 700MHz... it's actually doing more work per cycle than an older processor that is clocked higher. In other words... you shouldn't just look at the MHz number.

Apparently Intel finally has some decent IPC gains in this generation.

And remember... that's just the base clock. It boosts to 3.5GHz single-core and 3.2GHz all-core.

Though we should probably wait for benchmarks and real-world tests before we freak out about it... :p

Do you understand anything about IPC?

This CPU line-up is probably as good a clue as any as to why the 12-inch MacBook was killed (for now). The 2015 MacBook launched with a 4.5W Y-series CPU. Last year's Y-series CPUs then went to 5-7W. Now we're at 9W. Apple designed a laptop based on the assumption — presumably promised as such by Intel — that Intel would keep iterating on a roughly 4.5W TDP CPU, and they failed to do so, even after this process shrink.



This is good, actually. Low clock rates means Intel has some breathing room for future generations at the same process size to offer more performance simply by cranking up the clock rate.



9W: probably the MacBook Air (which is currently at 7W, but presumably Apple has learnt the lesson not to trust Intel on that).

15W: low-end 13-inch MacBook Pro.

28W: possibly the higher-end 13-inch MacBook Pro, but Apple probably wants more options for that. Also, this CPU model won't ship for a while.

Critically, none of these are even remotely an option for the 15-inch (16-inch?) MacBook Pro, which likely won't see another CPU upgrade until Comet Lake-H in Q2 2020. It'll offer up to ten cores, but it will still be at 14nm and still use a revised Skylake architecture. Still no LPDDR4, even.

Yep guys, I was making a funny. I mean, you have to admit that it's pretty weird to see 700MHz in 2019. Takes me back to my youth and the race to 1GHz. Good times.

Which TDPs are MacBook pro compatible? All of them?
Yes, though all have fewer processor cores than even i7s in the current mid range MBPs. So far there is no i9 variant. Waiting for Intel to release usable gen 9 mobile chips in the 45W TDP range currently used in MBPs.
 
2015 MacBook: Core M, M-5Y51, TDP 4.5 W (Broadwell)
2016 MacBook: Core m5, 6Y54, TDP 4.5 W (Skylake)
2017 MacBook: Core m5, 7Y54, TDP 4.5 W (Kaby Lake)
2018 MacBook Air: Core i5, 8210Y, TDP 7 W (Amber Lake)

2019: Core i5, 1030G5, TDP 9 W (Ice Lake)

The 12" MacBook chassis was designed for 4.5 W TDP. The retina MacBook Air for (at least) 7 W TDP. Those Ice Lake Y-series chips really might not fit into the no-fan 12" MB body thermally.
[doublepost=1564740266][/doublepost]
They didn't kill it, they've just added a TouchBar (and TouchID). It still uses the same class of processors as the non-TB 13" MBP, still has the same two TB ports and still has the same internal layout (which is different from the 4-TB port 13" MBP).
[doublepost=1564740455][/doublepost]
Given that Apple had offered a MacBook without TB for four years, why couldn't they release an ARM-based laptop that, like the iPad Pro only comes with USB-C ports? And once we discard TB, what other "caches, memory controllers, PCIe and other stuff" would a MacBook need that are not in an iPad Pro today?
Earlier versions of the MBP line had to power hungry support spinning drives. Too, TDP is a peak figure of merit. Current processors are designed for processing demand variation so average demand now is much lower than TDP.

No Mac laptop since 2012 has had “power hungry support spinning drives”.
