making its own custom-designed chips

for the Mac at WWDC 2020.

- Were announcing that the Mac is transitioning

to our own Apple Silicon.

- It's only the second time ever

that Apple's made a shift like this.

The last one was when it shifts from PowerPC chips

to Intel chips in 2005, and it was a big change.

It made Macs more like PCs,

so much so that those Macs could even run Windows.

But this change is very different,

and it's gonna make your Macs a whole lot more

like an iPhone instead.

Apple may be new to making Mac chips,

but it's actually been making processors

for a really long time.

It's actually one of the biggest advantages

to Apple's process.

Ever since the iPhone 4 and the iPad a decade ago,

Apple makes the software, Apple makes the hardware

and Apple makes the chips that it all runs on.

Every part of the process is under Apple's control,

and now Apple's potentially poised

to bring those same benefits to the Mac.

Apple's complete control over its devices

is why your iPhone can get updates

years after Android manufacturers have given up on support,

or why your iPhone can feel so snappy

even though it has far less RAM and system resources

than an Android flagship.

Apple gets to custom design its chips

for each of its devices instead of relying

on the same Snapdragon processor

that every other flagship's using.

Compare it to something like the Google Pixel

and the benefits of Apple's approach are clear.

Google makes Android, and it can do incredible things

on the software side like the amazing AI camera stuff,

but it's struggled for years

just getting the hardware right.

Or look at Samsung, which is an expert at hardware design,

but it's struggled with software

and its weird Android add-ons for years.

One analyst even estimates that Apple

spends four times as much on built-to-order parts

for its iPhones than it did just five years ago.

In other words, today's iPhones

are more uniquely Apple than ever before.

The switch to ARM, which the company refers to

as Apple Silicon, marks the third

major platform shift for the Mac.

The last one was in 2005 when Apple switched to Intel chips,

which then-CEO Steve Jobs explained at the time

as being for a very simple reason.

- We are gonna begin the transition

from the PowerPC to Intel processors.

Why are we gonna do this?

Because we wanna be making the best computers

for our customer looking forward.

- PowerPC just couldn't keep up with Apple's ambitions

of smaller, faster and longer-lasting computers.

It's easy to see the impact that those Intel chips brought:

new designs like the MacBook, the MacBook Pro

and the ultrathin MacBook Air,

which have come to define a generation of laptops

over the last 15 years.

And the switch to ARM promises

even better power consumption than Intel,

which means that we could have a similar jump forward

for even thinner and lighter designs

with better battery life than ever before.

There are other benefits too.

Apple won't have to rely on Intel's roadmap

for new chip designs, something that's seen delays

that have slowed down the entire computing world

over the past few years.

And by not having to rely on a third party for chips,

Apple can cut down on its costs for those processors

by up to 40-60%, although knowing Apple,

I wouldn't get your hopes up that you'll see those savings

passed on to the price of your next Mac.

While all that sounds great,

there's still a big elephant in the room

when it comes to the ARM transition:

how fast are Apple's ARM chips actually gonna be?

And the answer's unfortunately: we don't know.

Apple's made some big promises here,

claiming that its chips will offer better performance

and lower power consumption than Intel's,

across both desktops and laptops.

And there are rumors of a 12-core chip in the works

that would be vastly more powerful

than Apple's best chip right now,

the A12Z, which powers both the iPad Pro

and Apple's own original ARM developer kits.

But Apple makes a lot of different types of Macs,

and ARM computing is a relatively new field

when it comes to building desktops and laptop computers.

The most powerful devices we've seen

are tablets like the iPad Pro

or early laptops like the Galaxy Book S

or Microsoft's Surface X.

No one's actually made even a high-powered laptop

powered by ARM chips, to say nothing of desktops

like the iMac or a full-fledged professional device

like a MacBook Pro or the Mac Pro.

There's also the issue of software.

A new platform means that developers

are gonna have to port their apps over

or rely on Apple's Rosetta emulation software,

and much like that Intel transition in 2005,

things are probably gonna be rocky for a bit.

A lot of these questions are still unanswered.

We don't know how well Rosetta 2 is going to work

and some developers might just not port their apps at all.

You only need to look at the Surface X

to see that transitioning from x86 to ARM

can lead to big issues with app support.

I'll let Dieter explain more about that.

- (sighs) So let's talk about apps.

So the apps that run best on the SQ1

are the ones that have been compiled to ARM64.

That means they're 64 bit and that they've been designed

to run on this chip.

Those apps are fast and they don't

hurt your battery life much,

and they are pretty rare, actually.

There are a bunch of Windows apps,

and especially the newest and most powerful Windows apps,

that are 64 bit but designed to work for x86 and not ARM,

and they don't run at all.

I'm also talking about games.

Games are a full-on nonstarter.

I don't mean that they're slow.

I mean they literally don't start.

So here's a game that I love, it's called "Into the Breach,"

and it's a disaster.

What is happening on the screen here?

Well, okay. You can play "Angry Birds 2".

Woo!

See, everybody has that one app that they need,

and mine's Lightroom, and you have to do a ton of research

to figure out if your app actually works on this computer.

There's no list that you can just go look it up on.

I will give Microsoft some credit

for making an ARM machine that's fast enough

and that runs real Windows 10 instead of RT

or Windows S or whatever.

And again, this is one of the best-looking computers around.

But the apps are not ready yet.

- With all that uncertainty,

there are a couple of good signs though.

Craig Federighi, Apple's senior vice president

of software engineering, says that he expects

that most developers will be able to get their apps

up and running within a couple of days.

And during the keynote, Apple demoed several key apps

already running on ARM.

- So of course, when we updated our apps for Big Sur,

we built everything as native for Apple Silicon.

Some of the biggest Mac developers

have already gotten started.

Let's take a look at Word.

And PowerPoint.

Here's Lightroom running native on Apple Silicon.

Here's a five-gigabyte Photoshop file.

Final Cut Pro.

Here it is running on Apple Silicon for the first time.

- Plus, Apple has a major ace up its sleeve

that neither the 2005 Intel transition or Microsoft had:

the iPhone.

Developers have been building iPhone

and iPad apps for years,

and all of those apps will run natively
