x86-64-v3 is AVX2-capable CPUs.

by benatkin - > you will not be able to transfer your hard-drive/SSD to an older machine that does not support x86-64-v3. Usually, we try to ensure that moving drives between systems like this would work. For 26.04 LTS, we’ll be working on making this experience cleaner, and hopefully provide a method of recovering a system that is in this state.
Does anyone know what the plans are to accomplish this?
by dfc - Getting a 1% across the board general purpose improvement might sound small, but is quite significant. Happy to see Canonical invest more heavily in performance and correctness.
Would love to see which packages benefited the most in terms of percentile gain and install base. You could probably back out a kWh/tons of CO2 saved metric from it.
by Hasz - Over the past year, Intel has pulled back from Linux development.
Intel has reduced its number of employees, and has lost lots of software developers.
So we lost Clear Linux, their Linux distribution that often showcased performance improvements due to careful optimization and utilization of microarchitectural enhancements.
I believe you can still use the Intel compiler, icc, and maybe see some improvements in performance-sensitive code.
"It was actively developed from 2/6/2015-7/18/2025."
by watersb - What are the changes to dpkg and apt? Are they being shared with Debian? Could this be used to address the pesky armel vs. armel+hardfloat vs. armhf issue, or for that matter, the issue of i486 vs. i586 vs. i686 vs. the many varieties of MMX and SSE extensions for 32-bit?
(There is some older text in the Debian Wiki https://wiki.debian.org/ArchitectureVariants but it's not clear if it's directly related to this effort)

- Announce was here: https://discourse.ubuntu.com/t/introducing-architecture-vari...
and key point: "Previous benchmarks we have run (where we rebuilt the entire archive for x86-64-v3 57) show that most packages show a slight (around 1%) performance improvement and some packages, mostly those that are somewhat numerical in nature, improve more than that."
