After Apples announcement of M1, I feel like it is mandatory for such a laptop test to discuss power per watt and for how long you can game on the 11 vs 12th gen processor. I also feel like it is worth mentioning that 12th gen laptop is priced ~ $150 over the 11th gen. If you're coding against an online build system and 11 last an extra hour (or whatever), it's a no-brainer to stick with the old one.

You can't game on M1 or Mac AFAIK

Completely untrue. I replaced my gaming desktop with a Mac Mini for several months. I was able to play many games:

* League of Legends

* Civilization 6

* Stellaris, EU4, etc.

* Minecraft

* Factorio

I have been using a 6800U on Linux for the past two weeks. With kernel 5.18 almost everything is supported out of the box. The few issues I have: - Kernel logs show that the GPU driver crashes from time to time. When it happens the screen freezes for a few seconds but recovers. - HVEC hardware decoder gives green artifacts on VLC using VA-API. - It seems not to support advanced power management, on battery the CPU wi…

AMD does automatically switch to a "power saving" profile on battery that lowers power consumption significantly vs on charger, but if you want, you can tweak even further with a fantastic tool: https://github.com/FlyGoat/RyzenAdj - it's a simple CLI util so easy to set up w/ udev rules to run automatically. On my old Ryzen laptop, I have it set to run `ryzenadj -f 48` when I go on battery, which limits the temperatu…

Is it possible somehow to set separate CPU/GPU power limits like is possible on the steam deck?

I believe Intel 12th gen is not properly tweaked yet, currently the benchmarks show that the battery performance is worse with 12th gen than 12th gen. But if you 'limit' the chip and force the usage of the efficiency cores then you should be able to beat 11th gen.

Good to know ty!

That's super exciting, but I'm not familiar with Xcalibyte. are they a good and reputable maker?

Is frame.work a good and reputable maker? Not saying they won't turn out to be, but they are still young considering the space they are in. Similar holds for any other hw maker that is only starting out!

Yes I think frame.work is a good and reputable maker. They are indeed still young, but they've made and kept a number of big early promises, and have been consistently shipping. There are some bugs/quality concerns but I'm confident they'll work them out.

I've bought hardware before though from companies I'd never heard of, and either never received it or when I did it was much poorer quality than advertised or was so long after the order that I'd nearly forgotten about it. Would hate for that to happen with xcalibyte

Maybe the new efficiency cores improve battery life over the 11th gen Intel CPUs but they're still far from the battery life of AMD or Apple silicon CPUs

For sure.

Apples M1 only worked because everything is in one chip. Very different from the goals of framework. There aren't any vendors offering M1 competitors either.

AMD's laptop CPUs are also "everything in one chip." Intel still has a separate chipset die on the package as far as I can tell.

This is not true. AMD CPUs do not include NVME controllers for example. There probably are more things AMD does not do on the CPU itself.

I've played with an AMD 6800u laptop and I would say it's the ideal x86 laptop chip right now. Normal usage at the 12w mode or light gaming at 20w mode was super impressive. Even though 12th Gen Intel chips have made great performance gains Intel is still relying on unsustainable high turbo boosts to get the benchmark numbers. I just recently stumbled across these two otherwise identical laptops. https://psref.lenovo…

At least on most ThinkPads, the AMD versions lack Thunderbolt 3/4/ USB 4.0 Full Feature (e.g. including TB) so if I have a Thunderbolt docking station, it will probably not work. Nobody confirmed to me, what would work in such a setting. Will Lenovo/ AMD provide USB 4 upgrade using firmware? Of course, the next question is the potentially asymmetric RAM on the ThinkPads with one channel soldered and one SO-DIMM slot,…

The newer AMD 6xxx series supports Thunderbolt 3 and USB 4 (USB 4 spec includes TB3), which has quite a few compatible docking stations available

Also note that Cinebench R23 is a terrible general purpose CPU benchmark. It uses Intel Embree engine which is hand optimized for x86. It heavily favors CPUs with many slow cores even though most people will benefit from CPUs with fewer, faster cores. Cinebench is a great benchmark if you use Cinema4D, which I asumme 99.99% of the people buying these laptops won't use. Cinema4D is a niche of a niche. Geekbench is far…

To clarify, Cinebench correlates poorly with gaming, office software, web browsing, and video editing. Those are what the vast majority of people buying laptops will use it for. For people that code, it also correlates poorly with parallel code compilation.

Thanks for your input, this isn't said enough. So many CPU benchmarks aren't effective at evaluating the general use case and yet are held up as this golden standard

Because I have visual studio open, a solution loaded and organized with all the files I need for this sprint, SSMS with the servers all connected that I need, all my tabs open to see my jira board, support tickets, etc, a notepad doc i was using to take notes on a phone call, my ssh key loaded into pageant, and if my computer reboots, i'm going to forget half of that when it starts back up and lose 30+ minutes trying…

In our network there are no developers. That would be a different usecase which would require different policies. All tools required by staff are online and autosave everything. This in fact is another reason why proper restarts are enforced nightly, as most browsers with multiple tabs of heavy web apps start misbehaving very quickly. Forcing a nightly shutdown of browsers is an added bonus of proper shutdowns. Be aw…

Ok - that makes sense. Obviously being on the dev side of things, I've never worked for a company that didn't have devs (and admins, devops, etc). Sounds like it definitely works in your case.

Is this an arm MacBook? It sounds a lot like an Intel one.

Unfortunately, all Macbooks will get pretty hot running Docker, Apple's fan curves will always let your machine heat up before being audible.

I am not sure how accurate this is - I have run my Macbook M1 in clamshell mode for the past year and have almost never heard the fans, and never even felt heat coming off of it, despite having Docker / JetBrains full IDEs open
