Tangential, what are the options for an AMD to drive a 5k screen? I chose an Intel laptop and then Mac with Thunderbolt. Seems AMD laptops with Thunderbolt are rare but exist, and upcoming USB standards could drive 5k.

These AMD chips support DP2.1, USB4 which should do 8K60Hz HDR. That is what you should look for instead of thunderbolt.

> but the device failed to win us over in terms of multi-core performance If a dev machine I'd get it, but biz users are email and a few small spreadsheets. I don't get why biz users need multicore anything.

Webapps like Salesforce, Gmail, Slack, Google Docs drink resources. They occasionally get stuck pegging an entire core indefinitely. Also Microsoft Teams.

When line of business apps like email use 1GB of memory each you need a faster machine than if you use mutt.

As a counterpoint, I've had a 12-gen Framework (i7, 32GB RAM) for almost a year and half now. I use Docker on a daily basis (using Windows and WSL2) and it works fine for my development workloads. Like other Intel laptops I've had, the fans do come on occasionally but not very often. I do have some qualms about this laptop but I'm happy with it and the tradeoffs I chose.

That's actually quite interesting - same configuration with i7 1280p and on windows and wsl2! Blah, I wish I knew what you were doing differently. The moment that Chrome, Slack, Docker and PyCharm are up and running, it gets quite loud :(

Honestly, not much! I also run PyCharm, Slack, Firefox, and other things. This does get the fans spinning from time to time but no so much to make it a complete deal breaker. When it happens I may open task manager and see what's up in case there's something odd going on.

Seems like I lost access to my old account, so had to create a new one. I just bought this a couple of days ago. I went with the ryzen, OLED version and 32GB RAM. I ordered without an OS and run Ubuntu on it. The decision was between T14 , the carbon x1 and the framework. My previous laptop was a x1 gen 3. The laptop hinge broke :/ I absolute love this machine. Impressions so far: * Ubuntu 23.04 and Gnome runs so goo…

What kind of programs do you use? I can get ~20 hours on a zenbook flip with OLED, because I use mostly terminal programs (black background, so most of the pixels are off). Have you tried running powertop for a bit? It would be interesting to see if the screen was consuming most of the power, or if the draw can be attributed to a particular device (maybe it is something useless like a Bluetooth radio that you can shu…

Also the power tuning in power top can be amazingly helpful sometimes. powertop --auto-tune is usually fine!

Thankfully modern kernels have turned a bunch of settings on by default. But for a while a bunch of pretty simple power saving measures like iirc the sata link wouldn't go into low power states by default.

According to the spec sheet, they come in models up to 32GB soldered: https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_T...

I'm sorry, I had the T14 up on Lenovo's site, not the T14s. It looks like the T14s has no RAM sockets, and they only sell it with 16 GB of soldered RAM (unless there's a way to special order it or something). https://www.lenovo.com/us/en/p/laptops/thinkpad/thinkpadt/th...

in Europe - you can by 32GB version from the shops.

Mostly just web development stuff - firefox, terminal, vs code, thundebird, background music etc. I am hardly ever without power so I haven't really spent much time on this. But thanks for the suggestion, will look into powertop. I assume this means that you use linux on zenbook flip ? Which distro do you use?

As for resolution, I wanted to try to run it lower res but Ubuntu crashes in lower res :/ Will have more time on the weekend to investigate.

What is the hardware decoding/acceleration scene with Linux on modern laptops such as this?

1. Can you expect to watch Netflix, fandom video services like F1tv without tinkering with some tunables in the OS?

2. What is the sleep/wakeup situation like? Can it do MacBook style - shut your lid when you go away from desk for a coffee and come back and open the lid for instant ON(back to work)? Reliably?

3. Also, does x86 laptops have the sane sleep state back? Or does it still keep sipping power and heat up while stashed in the backpack?

The only thing I hate about powertop is seeing how much power my wireless interface draws even when it is mostly idle. I’m not downloading a website, wlo1, so why are you on?

Maybe I need to map a new key in my window manager: rfkill unblock wlan on keydown, rfkill block wlan on keyup, hahaha.

> How come? Most video being 16:9 means you useball of the screen you have, 16:10 adds bars on one side doesn't it? Do you use your laptop to work, or just watch video all the time? Because if you actually do work, 16:10 or 3:2 is much better.

I'm not writing code, but I edit video and write text on a 16:9 and have never thought that the screen format had anything to do with anything else than video crops. What do you get out of 16:10 for "working"?

16:10 is tall enough it doesn't feel like you're viewing your screen through some kind of short fortified viewport-slit.
