Apple’s M1 chip fastest laptop CPU in the world

I am not optimistic about how much performance "Rosetta 2"

I never noticed things being unacceptably slower in Rosetta 1, when the PowerPC - Intel transition occurred. It was totally seamless.

Will have compatibility issues too, but should hopefully still be a good trade to be able to run iOS apps.

I don't know if this requires some special developer software, or if it's native. If native, that's a big deal.

Why?

You can already execute iOS code on Intel chips. Just start an iOS virtual machine. Does it matter if it’s a Little faster on the M1?

I suppose one could jump through those hoops, but if I could just click on an app that's installed on my phone and run it on my Mac, that would be simple and a big selling points for those who don't know what a "virtual machine" is.

[Doctor Phibes]

I'm about 70% sure that Klaus is a virtual machine.

They could very easily make it such that it's just a click on the Mac now. In fact, there's loads of X86 code which those Macs need to execute and the way they execute it is also via some kind of virtualization/emulation/simulation. The main advantage of supporting it directly would be potentially higher speed, but iOS applications usually have fewer resources than what a laptop offers. Overall, I think the main business case for those processors is something else, such as maybe power savings or just good old politics.

Note the MacBook Air has only 8GB of RAM

Here's the 2020 16-inch MacBook Pro (i7)

I imagine the OS has something to do with the results (MacOS 11 is optimized for the M1 chip), but still that's pretty impressive.

[Doctor Phibes]

The 2020 Macbook pro uses the Intel Core i7-3720QM - isn't that a really old processor?

[Klaus]

I don't quite understand why the single core score is so much higher.

The base frequency is a little higher, ok. The caches are significantly bigger, that might make a difference. But I find it hard to imagine that the new chip can do that much more per cycle.

Here's a different MacBook Pro (13 inch):

[Klaus]

Yeah, it is impressive. It's not so clear, though, how well that translates into real-world performance. These are all synthetic benchmarks.

One should also add that Intel/AMD desktop/server CPUs are still way faster. The fastest AMD CPUs have a multi-core score of around 60,000.

I personally have always "philosophically" preferred RISC over CISC CPUs. It's nice to see RISC so much on the rise.

I have no doubt that there are many, many, "faster" chips.

The chip is just one part of the equation, see my "Big Sur" thread.

OTOH, that AMD CPU that scores 60K, is that available in a consumer machine for less than $2K?

No, of course not. I merely wanted to point out that this is not "the fastest CPU ever" or something, which somebody may prematurely conclude when looking at the numbers.

@Klaus intel chips are x86 chips (30 year old basic design). They have to dedicate silicon to compatibility with legacy commands, pipelines. Then there are some other features like virtualization which are important for business applications, that benefit from hardware acceleration (but are wasted if you don’t use it).

So in short - intel has a lot of design legacy to deal with and can’t just optimize for today’s common workloads.

Fair enough.

Perhaps the "Fastest CONSUMER CPU ever?"

I don’t think that this is the main factor. CISC vs RISC, that’s the big difference.

Perhaps the "Fastest CONSUMER (except Mark’s) CPU ever?"

FIFY.
