Running an array of benchmarks from the #Phoronix Test Suite on my old and new laptop to see how they compare.I expect to see similar single-core performance, but better results on multithreaded loads. They're also running different distros, which might skew some results.

The #System76 setup menu is somewhat minimalistic, but there's a version, and that's enough to confirm that it's indeed running my scratch build from git head.I guess I won't have to learn any recovery procedures today 😅

The NVMe drive is a cheap WD Blue, but I entirely expected it: I always buy my laptops with the minimum storage option because it's cheaper to buy NVMe drives separately. In this regard, #System76 is no different from other hardware vendors.Whenever I upgrade my PC or laptop, I simply move the old drive with my home and OS partitions. Thanks to #UEFI and Secure Boot, nowadays getting it to boot has become more complicated, but Linux doesn't mind moving across machines.

As @10leej already noted, the speakers are the only disappointment with the Lemur Pro.My ThinkPad X1 speakers weren't great, but these are truly dreadful 😖I mostly use my laptop with headphones, but I wonder if they could be upgraded with better ones? I'd definitely give #System76 a few extra bucks for mid-range speakers.

@freakazoid Even if you could, I would still recommend getting the cheapest storage option for the integrated "first boot" process and to try #PopOS at least once.#Ubuntu Jammy users will probably consider switching at this point. I think I'll keep using Fedora with KDE, but I would recommend PopOS to almost anyone who wants a polished and integrated Linux experience.

Final step: I move the NVMe drive to the new laptop and power up. As expected, Fedora 36 immediately boots.Actually, I got a glimpse of a blue screen during POST, but it disappeared before I could read it.

Some of you might be thinking that #System76 laptops are still not 100% free from proprietary blobs. And that's true. But please, appreciate how huge of a leap this is.I wished to see this happen for over a decade. In 2014, it was barely possible for a highly motivated geek to flash Coreboot on a 2-years old ThinkPad:https://codewiz.org/wiki/CorebootX230

Google shipped #Coreboot on millions of Chromebooks, bot those were low-end machines with smartphone-grade SoCs and not enough flash on board to be a proper developer's laptop.I mean, kudos to Google for liberating an entire market segment from vendor-locked proprietary BIOSes. It's just not the kind of machine I need every day.

@globalc Yes, I saw that #System76 use a custom tool:https://support.system76.com/articles/system-firmware/The "firmware-cli schedule" command creates a new boot entry and reboots into a firmware updater.I wonder what it would take to add support for standard UEFI capsules:https://uefi.org/sites/default/files/resources/UEFI%20Fall%202018%20Intel%20UEFI%20Capsules.pdf

If you have to compile C++ code, do it on a desktop with lots of fast cores. Keep in mind that modern Intel CPUs come with two kinds of cores: P (performance) and E (efficient, but slower).My #System76 Lemur Pro has 10 cores, but only two of them are P 😅The older Thinkpad X1 had a 10th generation Intel CPU with 6 cores (12 threads), but they're evidently much slower, at least when compiling LLVM.#benchmarks

@codewiz @globalc It takes somebody willing to work with UEFI enough to make it all work. The UEFI efforts in coreboot-land are rather barebones because nobody _wants_ to deal with that mess created by a committee of architecture astronauts.

@naufraghi There are several benchmarks showing generally better performance with Intel's distro ClearLinux. It's likely due to culling expensive kernel options AND better cpu tuning flags for the userland.https://www.phoronix.com/search/Clear%20Linux

@penguin42 Good question, I'll try to find out... In longer compile benchmarks, thermal behavior matters too, so perhaps using all 8 efficient cores might be better than using 2 cores that must be throttled down after 30 seconds.
