Our first price for a laptop with the Snapdragon Elite X just leaked:

14" Galaxy Book Edge: 1800 EUR with 16+512GB.

The same laptop with Intel Core Ultra apparently starts at 1899 and a similar memory spec 13.6" MacBook Air goes for 1749 (though you have the option for lower specs).

A bit disappointed tbh. Galaxy Books always launch weirdly expensive & I guess this might include touch + OLED + pen, but Windows really needs to at least match prices IMO

Good news for those wanting to build out a custom Arm64 desktop:

ASRock Rack has a mobo+Ampere CPU combo that restocks every few weeks on Newegg: https://newegg.com/p/N82E16813140134

And Noctua's prototyping two new LGA 4926 coolers (pictured: NH-D9 AMP-4926 4U)

I am building out my 45Drives HL15 server with this board and will hopefully have a video up on it soon!

Full review will take longer though—need to test out software, get an idea of power draw, test performance/networking... but so far so good!

I'm so happy to announce that the first NPU driver has been accepted in Mesa.

Have written a bigger update to celebrate this and properly thank everybody who has been supporting me in this amazing trip so far.

We're done here, contention totally gone, improvement now +300% for both cases. I believe it's weekend time.

For the 2023 ClangBuiltLinux meetup, I decided to revisit my benchmarks comparing how building LLVM with different optimizations such as LTO, PGO, and BOLT can impact how fast it can build Linux kernels:

https://github.com/ClangBuiltLinux/cbl-meetup-2023/blob/9b399fe8f3b886d549105a82068e3a441e496b46/nathan_making_llvm_faster_with_build_time_optimization_technologies.pdf

TL;DR: PGO and BOLT can give huge wins, LTO not so much.

It was pretty wild to see how much PGO made a difference, almost twice as fast in some cases... The kernel.org LLVM toolchains I provide are built with PGO and BOLT for this reason:
