The purportedly increase of performance in older devices is accomplished by overclocking the CPU faster rather than any underlying core code optimization. This means that battery life will be impacted negatively for those older devices... It all plays in the favor of selling new devices.. :)
False
 
These Apple Ax chips have been amazing for years.

One thing I don't understand though - many speed tests on youtube actually show modern android phones (i.e. S9) launching apps faster than the iPhone.

Any idea how this is possible? Is iOS that bloated? It seems like Android should have no chance given much slower cpu's and the overhead of java.

They are packed with more RAM and usually more cores. I wouldn’t base performance on app launching time alone. This doesn’t mean much. I’d be more interested in the time it takes to export video.

UI design and animations. Android has been designed to skip the fluff and execute actions as fast as possible. That’s one reason. However the iOS CPU scheduler has been tweaked in iOS 12, which is the biggest reason for the speed improvements. So I think the results would be different now.

Those YouTube videos are so unscientific it’s not even funny. Take 2 stop watches and tell me if you can, at least once, get them to stop at the exact same time using 2 hands at once. Nearly impossible which completely invalidates any sort of speed test comparison.

I did see one guy is using a machine now. Still a pretty silly test IMO
 
A Hackintosh is hardware running MacOS without Apple's approval/blessing. So an iPad would be included.

The only reason the Hackintosh is possible is because Apple is using Intel CPUs. That’s it. If they went to custom ARM, this would be over in a heartbeat. Keep I mind that Hackintosh builds are severely limited as far as what pieces of hardware are compatible and updating the OS usually breaks everything. It is not a solution for mission critical machines. It’s more for people that want to use a high-end nVidia GTX1080ti or RTX1080 with macOS.
 
Good job finding drivers to run macOS on ARM, though. This is entirely impractical without Apple’s help.

Who said it was practical?! Have you seen the crazy things people build just for the heck of it? If not check out YouTube it will bkow your mind.
 
I don't understand why a smartphone needs so much computing power. Is it because of mobile gaming?.

I'd say it's similar to what tablets were to laptops. Tablets as a whole were designed as an alternative for lightweight tasks. Now our phones are basically cannibalizing on tablets. People are doing similar things on their phones such as editing pictures, playing more intense games (as you've mentioned), recording video and editing, docs editing, etc.

Nope, never done any of those things, never likely to either. Why bother when a Desktop is a far superior user experience?
 
Is that true about two a12’s in the iPad Pro?
Very unlikely.

The A12 has two fast and four "slow" CPU cores. Two A12 (that is two separate chips) would have enormous design challenges. What would be much more likely would be a single processor with more cores. (Not that I expect that either, just saying it is more likely).

Let's say CPU A takes 100ms to perform a given operation.

Let's say CPU B takes 10ms to perform the same operation.

CPU B can be in a 'sleep' mode for the other 90ms, not consuming anywhere near as much power.

Then you might measure things like 'the average app launch takes 90% less power than before'.

Sure, there's plenty of power optimisation possible, but 'just get stuff done quicker' is an excellent approach. If you can keep going faster whilst sipping the power, you're going to see benefits.

I wish we knew more about how the Ax chips were designed. Back in the old PowerPC/Intel wars, we'd get detailed reports about how architecture changes improved performance in different ways-- now it's just a black box to benchmark.

I'm sure there's a ton of innovation happening to achieve these levels of performance/efficiency, but somehow it's less exciting without being able to see behind the curtain.

Read the AnandTech article. Lots of good information there.

How big is the intel 8700k, and how much power does it draw?
Imagine if apple put more cores in a new a series chip without the limitations of size and power draw?
Apple doesn't make them, but you can buy ARM CPUs with 32 cores that are used in servers, drawing around 120 Watt.
 
"If Apple doesn’t develop marzipan, the Mac in 5 years time is basically going to be a legacy platform (for most users) and a highly specialised one for pro users."

As the iPad Pro becomes more powerful and takes on more tasks designed for the Mac, the future of the Mac is as a specialized device for Pro users. I could be wrong, but I still Marzipan as nothing more than a way to run iOS / iPad apps on your Mac.

My take is that it will incentivise developers to bring iPhone apps to the Mac, which in turn means Mac apps will run in ios as well, and the biggest beneficiary appears to be the iPad.

So it feels like one roundabout way of getting people to develop more apps for the iPad.

That may be true for you, but a growing plurality of people in the world already use a phone as their primary (and often only) computer.

Because if you write an app you want to sell it to as many people as possible; you target the low-end not the high-end
And if a high-end up needs 1GB of RAM, 4GB means you can run four of these apps.

Never is wrong. They have in the past. Heck, they did it on the original iPhone, and sent me a refund for the difference after the price drop.

Not recently. But of course the technology in their phones has gotten more expensive, not cheaper.
If you look at prices for _the same_ phone, they have actually gone down quite substantially. Something like an iPhone 7+ has gone done in price quite a bit since it was introduced. (And it used to be top of the range, now it's the cheap model).

Why do people still bring up the "PowerPC to Intel transition" what makes people think it's gonna be that easy to go from Intel to an A12?
There will never be Intel emulation for ARM processors - because there is no need to. Most software needs nothing more than being re-compiled. As an iOS developer, you can already run iOS software on an Intel processor. And you can submit apps to the App Store that will run on any future processor.

Rosetta? Horrid experience & phase.

The vast majority of people, myself included, would strongly disagree with you.

And your evidence is what exactly?
 
It’s really amazing what Apple has done here. We all have to appreciate the design and technology. A chip so powerful and efficient at the same time. Just ran an Antutu just to see. Got a 364,000. Insane.
 
Apple chips are much better than Intel, which is why the upscaled version will dominate every class of machine in the very near future.

I'm a very casual iPhone user, and even I use these things. It really has nothing to do with user experience, but more with convenience and intuition.

Let's talk about photo editing. Much of the camera editing software on the iPhone lets you quickly add filters, modify attributes, and send it out via email or post to social media. You can do this without being near a computer. I'd argue from a user experience, this exact flow is much easier on a mobile phone than a desktop primarily because you don't need to find and sit at a desktop to do this.

The purpose for the increase in computing power helps with faster transcoding/transmuxing of media out of the iPhone.
 
Synthetic benchmarks are not the entire story. Just tells you a One Sided story.

That said, it’s quite remarkable how a mobile CPU is almost on par with a last gen Desktop CPU. However, the grain of salt here is if the A-Series CPUs have the same CPU features as the Intel chips. My guess, most likely not.

I don’t think they have virtualization support for instance in an A-Series.

It’s all well and good to have a supercomputer in your pocket (at significant cost mind you), but that just makes the neglect of the MacBook, Mac Mini and iMac lines all the more stark.

If Apple only put a fraction of the effort into Mac as it does the iPhone.

There already is for windows, I don't see any reason Apple wouldn't do the same on mac for the first year or two to ease transition: https://docs.microsoft.com/en-us/windows/uwp/porting/apps-on-arm-x86-emulation
