Can someone explain the 8gb obsession (edit: 16gb is possible, but why not more) ? is there a real limitation with this architecture or are they just making a business decision so they can sell multiple models over 2-3 years instead of creating what the market wants immediately

There's no 8GB limitation. You can order one with 16GB memory.

The tech specs page shows up to 16GB of unified memory, but the store itself only shows 8gb?

Look how big the escape key is on that keyboard, finally, revenge for the touch bar!

I like the direction Apple is going here, I assume they will have higher end iMacs later this year or early next year, and that's what I'll be waiting for.

I'd like 27 inches of screen, at least 16GB of ram, but preferably 32, and that's about all I'd ask for. My current workstation is a 2013 27" iMac fully upgraded (fusion drive, 16gb, good dGPU for its time - still plays Kerbal Space Program fine), so looking forward to more upgrades on the internals.

I've already run into the old WiFi and Bluetooth 4.0 as being bottlenecks and those are difficult to replace in an iMac by a normal person.

Earlier quoted context omitted.

former x86-64 hardware manufacturer view: the max TDP in watts of a CPU that can reasonably fit in something as thin as an air is a lot lower than a macbook pro or similar cooling solution (combined heatsink/heatpipe/blower fan). in the intel world there's a whole class of CPUs that absolutely max out at 8W, 12W or 15W, you can go somewhat higher in a fatter laptop.

Both Pro and Air use the same M1 chip. Same performance, clocks, thermal output. They just handle the cooling differently.

If I had to guess I'd say that the air probably thermal throttles or reaches a steady-state of lower performance at an earlier time than the Pro, if the pro has a larger cooling package on the same CPU...

If you were to sit the two side by side on a desk and run a complicated pure-cpu x265 1.5 hour ffmpeg encode of a 4K video from raw y4m, the pro will probably race ahead after about 20 minutes, after the heat has soaked into the air.

I am not excited at all for the Ethernet port to be part of the power supply. It just makes my job harder. I will probably be buying external 10Gbe adapters anyway. The memory is also a concern. They didn't show the memory in the summary slide like they did with the MacBooks and Mac mini. This is just disappointing. I hope 16gb an option. I really wish we could get back to 32gb. [edit] 16GB is an option according to…

I think you’re a holdout for the pro version. This one is only 24” anyway.

Still just 16 GB RAM?

I don’t see how this is appropriate for today’s MacOS. MacOS will use RAM. Currently it’s using about 34 GB of 64 GB on my machine.

I understood on their ultralight notebooks, but the iMac is not giving me confidence about what they might offer for their Mac Pro.

The lightness, size, wireless connectivity, and boot speed of this device makes it more likely to move around the house than a traditional desktop or even the recent iMacs. I could certainly imagine scenarios in which someone purchases multiple power cables, plugs them in throughout the house, and then brings the computer from their desk into the kitchen while making dinner or something. That is already a common prac…

Except this doesn't have a battery, touchscreen or keyboard attached. It seems extremely unlikely for someone to do this instead of just getting a laptop or tablet for this price.

Probably only introduced the 24inch because of maximum pixel output limitation of M1. The 24inch is 4.5k and it supports one external display up to 6k.

A 27”+ would require to push at least 5k (possibly 6k) for the internal monitor + 6k for the external

For comparison the M1 Mac mini supports one 4K display and one 6k display. So it seems that this is close to the maximum for the M1 chip

It also means that for us with 5k2k monitors we will not get back our missing scaling options (at least not with M1)
