I have the M1 air with 8GB and it's unusable with pycharm on an external 4K display.

Should be better when this land (next version) https://youtrack.jetbrains.com/issue/JBR-745 (switch rendering API in JRE used by Intellj/Pycharm to Metal for rendering)

I've been following that ticket for yeeears. Is it actually shipping in the next release?

Ah beat me to it! The idea that Mx swapping to NVME is essentially no-op from performance perspective is patently wrong.

I don't know what people are reading into my comment. I said _if_ SSD speeds were comparable to RAM, RAM wouldn't be needed. The reason we need it is precisely because disk is slower and cheaper.

I think people just want to argue, so they half read your comment.

This looks like what the Macbook (2015) wanted to be. Keyboard and single port aside, it was a fantastic form factor, albeit crushingly slow. Mine no longer holds a charge, and am eagerly awaiting replacing it with one of these. Over time I've also noticed I no longer care about having the fastest possible laptop, since my job provides me with an MBP and that's where serious work gets done. I have a feeling this is g…

New one is heavy, much more so than 12" one

12" was 0.92kg. New MBA is 1.24kg.

I can run my Samsung CRG9 (a 49” UW monitor) with one of my M1 machines (an original 13” Pro w/ M1) at 120hz with no issues, FWIW. I suspect it would probably have issues running 4K @120hz however.

Thanks, that's an interesting data point. Back when I had my M1 MBP, I never managed to get above 60Hz, and I found some articles suggesting that nobody could. I'm curious why you had more success.

In my case, I had to get a new DisplayPort cable (not all cables will support 120hz). Things were rocky at the start but I believe Apple also released an update to improve compatibility.

Why does my $500 Samsung Galaxy Book Flex have the webcam in a tiny little bezel and this thing has a giant notch?

Most likely design consistency; to have the same design element across all devices

make every laptop look the same with a huge notch even if its not strictly necessary...?

If the Touch Bar could refresh at 60 hz or something, maybe it's a display. But if it (as it actually is I suspect) a USB connected thing that refreshes very slowly, it's not a display at all. And the MacBook Air can take a USB "monitor" for whatever that's worth.

It seems to refresh fast enough to run Doom on it. https://www.theverge.com/circuitbreaker/2016/11/21/13697058/... Framerate's hard to determine from a youtube video of someone pointing a camera at it, single-stepping has some things seeming to move at the same framerate as the camera but redrawing the whole screen as the player moves around looks more like 1/3 of the camera's framerate to me.

True, but the "can run Doom" framerate could be 1 per minute. It obviously can update decently fast, but whether it's a "display" is arguable.

In addition to that, today's 2000 GBP are more comparable to 1600 GBP in 2012 due to inflation.

Also, software bloat means that the old macbook can't do shit with today's software.

My spinning-rust 24” iMac from 2011 mostly manages to trundle along with Linux Mint on it for my partner to use. LibreOffice and Firefox for web browsing, mostly.

Anything more than that and it chokes. Too many tabs, it chokes. Too many software updates, woo boy does she choke. That poor machine!

> a poor understanding of computers would be to think that speed is all that matters. > What good is 16GB of super fast RAM if the machine is swapping out to disk regularly? If the swapping is fast enough not to be noticeable, then speed is all that matters. In fact, if SSDs were about as fast as RAM, we wouldn't need RAM at all! The whole reason why we have all these layers of memory (disk, RAM, L3, L2 and L1 cache,…

Apple must've spent a fortune on marketing bamboozlement ("you don't need as much RAM with apple silicone") that even people on HN now seem to parrot it. NVME is around two orders of magnitude slower than DDR3 RAM, so as soon as your heap is tapped out you'll hit a performance wall. As I sit here and type this, my 10.15.7 Catalina desktop is sitting at 12.25Gb of used memory with 2 Edge tabs and an open Citrix sessio…

> NVME is around two orders of magnitude slower than DDR3 RAM,

No. Dual channel DDR3 went up to about 18 GB/s read and 14 GB/s write. [1]

The latest NVMe PCIe 5.0 SSD are about 13 GB/s read and 12 GB/s write. [2]

Apple SSD are about half that now, but most DDR3 users didn't have highest clocked dual channel RAM either. So roughly a factor of 2 or so at best, about a 50x difference compared to two orders of magnitude :-)

And for the first time, MacBook Air supports fast charge for charging up to 50 percent in just 30 minutes with an optional 67W USB-C power adapter. Anybody know if the 67W USB-C power adapter is finally stock? Edit: Nope, still gotta wait a month: https://www.apple.com/shop/product/MKU63AM/A/67w-usb-c-power... Other (bigger) chargers are a 2 month wait. Looks like Apple is still suffering from supply chain issues.

If that means they ship with something like a 45W that's just cruel. I bet the charge merely maintains when the computer is under load.

You can choose from either at no additional charge.

Not to be rude but this is an inaccurate and poor understanding of computers. The entire chip architecture of the Mac changed since 2010. 16 gigs of RAM on an M1-based chip gets you much, much better performance than 16 gigs on an Intel chip from 10 years ago. Even the RAM and SSD stats you cite are apples and oranges - both have gotten dramatically faster in the last decade.

> 16 gigs of RAM on an M1-based chip gets you much, much better performance than 16 gigs on an Intel chip from 10 years ago. Unless you want to run VMs. Then more RAM is generally more better.

While your second statement is probably true, do you actually disagree that 16 gigs of RAM on an M1 gets you much better performance than 16 gigs on an Intel Mac?
