Memory bandwidth is still 76 GB/s. One reason I’m moving science workloads to M1 is for the cache line size and memory bandwidth, which bump by factor 2-3x the speed.
"science workloads". What kind of science workloads?

I suspect you'll get downvoted into oblivion for your PoV by the pro-Apple HN crowd and even though I do agree with you to some extent on the the high pricing (a basic M1 MacBook is half my NET take home pay as a dev in Europe, and double my rent costs) but value is subjective to most people, and for most, buying into the Apple ecosystem the value the ecosystem brings to their lives is justified, otherwise they would…
The thing is, I’m not sure your laptop is better than an M1, let alone the newer gen ones. Apple is really ahead in the CPU game and I say that as someone who was never there fan.
Therefore I am more comfortable buying something that, while not the fastest in the world at topping benchmarks, is plenty fast enough (faster than anything Apple ever made pre-M1 which many users still use just fine), fits my needs better, is easier to repair/upgrade, and as an added bonus, is significantly cheaper than an M1, so I can take the difference in money I would have spent on an M1 and buying into the Apple ecosystem and put it into Apple stock and I'd be even better off in the long run :)) Everybody wins.

2 TB of NVME storage is little more than $200 off-the-shelf. 64 gigs of DDR4, high-bandwidth laptop memory costs ~$250. Even assuming Apple is springing for high-quality, high-speed RAM, $800 borders on insanity when other laptops offer similar configuration options at less than half the price. Apple's price gouging in this department is well-documented, I don't think I need to argue with HN users about that.
I just checked out some random Dell Precision laptop. They want $800 for 64GB RAM and $720 for SSD. Seems pretty comparable to me. Samsung 970 Pro 1TB is $270 on newegg, so it makes $540 for 2TB. Cheaper, but it's only PCI-E 3.

The other thing is that specs alone don’t tell the whole story. There’s plenty of x86 laptops that on paper have better looking specs than the MacBook Air, but few or none of them are as good at what makes a laptop a laptop — mainly, battery life and heat output. There are laptops that are thinner and lighter, like the Thinkpad X1 Nano that I own, but that thing can’t touch an Air in battery life, heat output, and in…
Meh, my Ryzen laptop, while not M1 level, handles performance, heat and battery just fine for my needs, considering it costs well under half the price of an equivalent M1, and, as a major necessity for me, is easier to repair/upgrade but most importantly, it runs both Windows and Linux plus all X86 binaries I could ever want natively and I have full control over it (on Linux at least), instead of the manufacturer dictating what I'm allowed to run on it.
M1s are great but they aren't the magic silver bullet that solves everyone's problems, as I have no use for benchmark topping chips that can't run the SW I use.
Does the method whereby they circumvent the T2 security enclave work on Intel-based Macs? I have a 2018 Mac mini which I would love to repurpose with Linux once the end-of-life support stage is reached.
There should be a driver to support apple NVME implementation, and that should get you to boot on a t2 mac.

> But how many HP/Dell/Lenovo etc laptops do you have from 2013 that still run like new? many I don't see many old macs around, because they're harder and more expensive to repair. > if replaced every year that's a big if. The assumption is that Pro market will drive general adoption. It's a false premise. Pro market, especially Apple Pro market, it's predictive of exactly nothing.
> I don't see many old macs around Just anecdata, but from walking through German trains, I disagree. I still see non-Retina MacBook Airs on some trays, for example, last sold in 2015. Some Mac models are clearly more reliable and maintainable than others, see the butterfly keyboard fiasco. But I think companies should be judged by their better products, not the duds.

> But how many HP/Dell/Lenovo etc laptops do you have from 2013 that still run like new? >> many I find that hard to believe. You're claiming plastic race-to-the-bottom laptop pc makers are building machines that last as long as all aluminium premium Macs? Fat chance. Re the software issue, yeah, that's a pain. I do plan on putting Linux on it when I replace it with another Mac laptop, probably a M1. But that just fu…
> find that hard to believe. You're claiming plastic race-to-the-bottom laptop pc makers are building machines that last as long as all aluminium premium Macs? Fat chance. I'm not saying that, at all. I am saying that people keep reasonably priced hardware for longer than Mac owners because they don't have money to waste and can actually repair and upgrade them for cheap.
> Amusingly, while implementing support for this in Linux, we ran into a bug in Linux’s ARM SMMU support that had been there ever since 52-bit address support was introduced. This was breaking systems with more than 256 TiB of RAM - I wonder why nobody noticed? Either way, Linux now correctly supports standard ARM systems with up to 4 PiB of RAM ;-). Interesting how working on new technologies helps improve existing…
Are there even ARM systems with that amount of RAM? I assume it's something in the order of what super computers use, but I don't think any of them are ARM. That doesn't sound that surprising to me that no one noticed if no one uses that much RAM.
It's still not really ready for prime-time, but I've got a M1 mac mini running debian as an arm64 build bot (and a few other small things) now, and I can say that the bits that work, work really well. Storage is fast, CPU performance is solid, PCIe for ethernet works just fine. Now if I could just get one with 64G of RAM and 2TB of SSD... ;) edit: the setup process is still far from polished but that's not unexpected…
> Now if I could just get one with 64G of RAM and 2TB of SSD... ;) Careful what you wish for. With the way Apple marks up memory and storage upgrades, you might be looking at a $5,000 machine there...

I literally just dropped £4,099 on a fully loaded MacBook Pro 16" with those specs. I could not be happier. Its going to be a great daily driver for many years to come. Also the construction is A+ and solid, makes my 2015 MacBook Pro feel cheap in comparison.
