The wild thing is, your benchmarks with turbo boost disabled (GB5 single: 617 / multi: 5163) almost identically match the benchmarks on levono's new ARM laptop[1], the Thinkpad x13s (GB5 single: 1118 / multi: 5776). True, Windows on ARM will likely keep on being a pain for some time, but linux support seems to be coming[2], and for those of us that target Linux ARM development anyways, this is one of the first perfor…

If I'm not misreading what you wrote about the x13s, isn't it 2x the perf of the turbo-boost disabled i5-1240P in single core? That's a lot! EDIT: Also confirmed that WSL2 runs natively on Win11 ARM. So you can have an optimized full Linux kernel running on the Thinkpad as well.

I mean, yeah, laptop CPUs will some times go like 3x slower without Turbo Boost. As others wrote, you can tune for battery life and keep it on.

Recently discovered that Infosec has now mandated that all laptops have sleep disabled (the reason given is to be able to do endpoint patching). ¯\_(ツ)_/¯ So I'm faced with having to log out and power off every day or suck up the cost of keeping the laptop on. /r/maliciouscompliance, here I come I suppose. Tempted to get one of these: https://us.amazon.com/Vegamax-Button-Ethernet-Internet-Netwo...

Yeah, at a previous company, the IT team were complaining about users disabling powernap or shutting down laptops as it meant they wouldn't patch overnight. But these laptops were in bags, the last thing I wanted was a mac to start a house fire by heating up in a bag, so fuck that.

These numbers are usually lower in real life There are data sheets and then there is real life. People were raving about AMD laptops before. I got a ThinkPad T14 AMD with a 4750U. The stated psref battery life is MobileMark 2014: 14 hr, MobileMark 2018: 11.5 hr. In practice that was more like 7 hours on Windows (with a mild workload) and 3 hours on Linux. The CPU performance was merely ok and I could get the fans blo…

Within a year the kernel should support proper Power management on these new AMD systems. I have a year old 5800H that went from 3 hours to 11 hours battery life in typical use, just due to kernel version updates. It's like a new system.

This. The newer kernels support amd_pstate and it's a big difference.

How is 12th gen compared to 10th gen, in your experience? My XPS 13 on a 10th gen i7 just becomes absolute syrup on battery, even if I put it in high performance mode.

I have an XPS 17 with 12th gen and it drains around 50% battery per hour on a zoom call. edit: My laptop has a i7-12700H, which uses more power than the cpu in the framework laptop. More thoughts: The laptop is pretty much always plugged in. When I'm out I carry a little 60W charger with me. However for other reasons I wouldn't recommend the XPS 17. I have a Lenovo legion 7 at home that I'm more happy with (cheaper,…

Zoom battery usage per hour should be a standard metric. Nothing kills a battery faster.

Exactly. Not just 1 model but you can compare identical ThinkPad models as well and AMD versions have significantly better battery life. Not only that, even last year's identical models with 11th Gen Intel CPUs have better battery life than their new 12th Gen models. So Intel's power efficiency actually decreased compared to last year, even though they introduced the hybrid architecture. In some instances Alder Lake…

Something was screwed up, very likely on Windows, definitely on Linux. My 5800H gets 9 hours of battery life on Linux with KDE (full glass blur effect, IntelliJ, Firefox, etc...), without any undervolting or underclocking, at ~80% battery, 1440p60 15.6 inch screen. And about a third of the power consumption comes from the desktop class SSD I put into it.

I am able to get 4 or 5 hours of intensive programming done on battery power... running multiple IDEs, Android emulators, browsers, etc. I've never tried it with a normal usage pattern because I only use battery power for working.

That’s pretty bad compared to m1. Less than half the battery life. Also Samsung laptops don’t last in my experience. They make short term tradeoffs at the expense of long term reliability.

I just got an M1 Pro 14” 10c 32GB RAM and while the battery life is great compared to anything else I’ve used, it’s not as amazing as I would have hoped.

I get around 6 hours from 100% with a light Webpack dev workflow + Docker for Mac running in the background (arm64 postgres and redis containers).

Is that normal? powermetrics shows package power bouncing around 500mW - 10 watts when compiling, which would suggest I should be getting a lot more battery life. Is there a utility to reliably check power consumption of the whole system? Stats.app seems to think my system idles around 5 watts and goes to 40 watts when compiling which is much higher than the package power and my screen is only 1/3 brightness.

Should I? I have docker-desktop for the things I need it for - building the odd linux native image, or running testcontainers for postgres, same as we do when building on linux - and it works great. But for the day to day stuff, no.

I’ve been considering an M2 air with maxed out ram for development and I’ve been wondering what kind of memory pressure people with Airs are facing. On Intel I needed 32mb for all the containers at work, with a fairly modest CPU, but I expect my own projects to be a bit lighter. None of the reviews are useful. All useless junk about exporting 8k videos.

I have an M1 Air where I max out the 16G RAM all the time. It works because swap works painlessly for me, but I would have been really, really happy with 24G (or better 32G). It works but I have unfortunately no breathing room in RAM.

Often, I use 11-18G, rarely I use 20-50G.

Definitely go for M2 Air if you like the form factor (I prefer the M1 Air’s form factor though).

What type of battery life are you getting on an Mx MacBook?

I'm getting about 10 hours on my M1 16" MBP running a JetBrains IDE and 8 Docker containers.

FWIW I get about the same battery life on Linux with an AMD laptop. It's not as power efficient under load but not having to run a VM for docker helps a lot.

In a laptop, I care far more about battery life and the fan noise. However, Intel 12th gen is only able to pull these impressive performance feats due to very high turbo boost clocks. It's not that Intel is bad, it's still pretty great but in the age of M1 I wish Intel released a processor with similar power consumption. I use my Intel i5-1240p with turbo boost disabled when on battery. Here's the geekbench with TB d…

The AMD offerings are much closer to M1 although they're not yet on TSMC 5nm so they don't quite match it. It's a historic event. Intel was #1 in laptops for an eternity. Even when the Pentium 4 was being outclassed by AMD Intel still kept the crown in mobile. This time around they first got overtaken by AMD and then by Apple and are now #3. Puts into perspective how huge of a miss their process node fail was.

I have a laptop with the AMD 6900HS.

The CPU is great. It’s power envelope and performance feel amazing.

My biggest complaint is the there is a very limited selection of Laptops with AMD’s chips, especially the top tier. The one I bought required me to replace the Wifi/Bluetooth card (it came with a barely “supported” MediaTek one) for Linux.

So far I haven't noticed any issues with the 16GB in my air, but then I haven't really been looking for them either. I run a couple of containers in docker desktop, my IDE (IntelliJ) and its builds/test-runs etc, a browser with a doze or so tabs, but little else of any particular 'weight'.

I have heard anecdotal reports of those on 8GB machines facing the spinning beachball from time to time. It's never happened to me.
