From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is the AMD Phoenix power draw really just THAT bad right now? (lemmy.world)

Tldr; Have tested multiple different Ryzen 7000 configurations on various kernels, and the power draw just seems really bad.

Been looking for a decent new laptop workstation that fits various tasks. Phoenix chips check a lot of the boxes that I want, but the power draw on Linux for these chips seems a bit...crazy.

The product docs say these chips are 35W-45W, but I figured that was just the range of maximums. What I'm seeing on fresh installs of various Debian variants is a CONSTANT power draw of at least 35W on the low end at all times. I've stepped kernel point releases from 6.0 to 6.6 to test out, and the later versions are definitely better at using a bit less power thanks to the amd_pstate_epp being included directly in the kernel, but this power draw is still there for the CPU package on idle.

A few different laptop models I've tested will only get 90 mins on battery because of this. I've now tried four different models from three different manufacturers, and all show the same type of power draw.

Is this just a "thing" with these chips? I understand they were modified from desktop to be a more mobile platform, but this is just terrible from an end-user perspective. I want the CPU and iGPU, and hell, even the FPGA XDNA thingie, but not when the machine can't run off of AC.

I'd expect the Framework to perform better than most since it was designed around this specific chipset. I have an order in for the 16, but won't be getting it til next year. Just looking for something until then.
