Why did you pay a fortune for 32GB RAM, a larger screen, and a dGPU if you don't need it? You could have bought a 13" MBP and saved enough cash to get the new Air and now have 2 laptops.

1. How do you know he didn’t need it? 2. Even if he didn’t need it, why assume he didn’t want it? 3. Why are you assuming that money is an issue for him?

Also: Why assume he would want to have two separate laptops

I've been holding onto my late 2013 15" MacBook Pro for almost 7 years now and it's wild to see it get absolutely out-spec'd by the MacBook Air. It's been a long time, but I've always convinced myself that I'm not missing out on that big of a processor improvement. I do a lot of audio work with it, but even then it doesn't always feel like a slow experience.

Your 2013 would be at a huge performance disadvantage to the 2020 Intel Air and Pro.

Those are supposed at just as much of a disadvantage compared to the new Apple Silicon Air and Pro.

That's where shock comes in.

All those thinking of buying the new MBA, are you not concerned about availability of applications? Not all x86 applications will have an ARM alternative, yet.

Had access to a DTK, and know even more devs who have one. Even that machine could run essentially all x86 software just fine with Rosetta (including things like dynamically loaded plugins). Only thing missing is virtualization, but that's coming soon (Docker & Parallels are working with Apple).

Air vs. Tiger Lake 1165: https://browser.geekbench.com/v5/cpu/compare/4306696?baselin... And the GPGPU: https://browser.geekbench.com/v5/compute/compare/1800719?bas...

The one you shared looked crazy overclocked or something(it says 4.7 ghz). Almost all other tests of 1165 is in the range of single core performance of 1500. This is more representative of the chip of the same laptop: https://browser.geekbench.com/v5/cpu/compare/4648891?baselin...

Their line from the video about being the highest performance chip in single core appears to be true. This is of course a synthetic benchmark but the single core result is very promising. Note that the single core and multi core scores exceed the top-of-the-line 16” MacBook Pro (9th generation 8-core i9 2.4 ghz). I actually made the call to sell my 16” for the new Air yesterday. It’s looking like a good call. Glad I’…

They need to put out a 16" MBA.

Yes, in fact, the A14 (iPhone 12) already surpassed most Intel chips: https://images.anandtech.com/doci/16226/perf-trajectory_575p... Intel is now #3

A modern mobile CPU with a TDP of 6 watts is beating a modern desktop CPU with a TDP of 125 watts? Is it just me or this seems too good to be true?

It is true. Note that a single core can only use ~20W so high TDPs only matter for multicore.

Nope. This transition will be fast. Not like PPC -> Intel at all.

Everyone is on Xcode these days and using much higher level frameworks. Adobe and Microsoft already announced early 2021 availability of native binaries.

Besides, Rosetta 2 is even more impressive than the original was. I’m betting it will be a breeze. 6 months in and almost everything will be native.

It's a mobile CPU with many silicon advantages (widest decoder in industry, memory closer, deepest re-order buffer of any CPU and much more) plus a sane ISA and optimized OS. So yeah, you're seeing the benefit of Apples integration. That's why even the Anandtech page calls that graph "absurd", because it seems unreal, but it's real.

Gotta be frank because it's not getting through: you're jumping way ahead here. Every time one of these threads has happened, there's an ever-increasing # of people who vaguely remember reading a story about Apple GeekBench numbers, so therefore this one is credible too - I used to be one of those people. This has been going regularly for 3-4 years now, and your interlocutor as well as other comments on this article are correct - comparing X86 versus ARM on GeekBench is nonsensical due to the way GeekBench eliminates thermal concerns and the impact of sustained load. Your iPhone can't magically do video editing or compile code faster than an i5.

TDP lost meaning years and years ago, and power usage isn't linear. The extra 100-300mhz at the top end is a huge impact to power.

Check out for example the per core power charts that Anandtech does: https://www.anandtech.com/show/16214/amd-zen-3-ryzen-deep-di...

Compare for example the 1 core power numbers between the chips. The 5600X 1 core result is 11w @ 4.6ghz, whereas the other two chips boost higher and hit 4.8-4.9ghz 1 core turbos, but it costs 17-18w to do it. Huge increase in power for that last 1-2% performance. So you really can't or shouldn't compare more power-concious configurations with the top end desktop where power is infinite and well worth spending for even single digit percentage gains.

And then of course you should also note that the single-core power draw in all of those is vastly lower than their TDP numbers (65w for the 5600x, and 125w for the 5800x/5900x).

Is geekbench accurate at comparing across different architectures?

Generally, yes. The benchmarks are calculating/computing the same things on both architectures, and the various sub-benchmarks are based on real-world non-trivial computational problems rather than microbenchmarks that are easily manipulated by instruction set differences.

Unless they are written in optimised Asm I would not compare across architectures, because there is considerable leeway in compilers and my experience has shown that a good human can often beat a compiler solidly --- at least on x86.
