Radeon RADV "ACO" Performance On Mesa 19.3 Looking Good

Phoronix - 6. Říjen 2019 - 1:17
With the ACO shader compiler back-end merged for Mesa 19.3 as of mid-September and more improvements merged since then, it's now very easy to try out this alternative to AMD's longstanding AMDGPU LLVM compiler back-end. ACO, which is developed by Valve and their contractors outside of AMD, is looking quite good not only for quicker shader compilation (more punctual game load times) but also helping the performance of some Vulkan-powered games. Here are our latest ACO benchmarks.

Ubuntu dostává podporu ZFS, Google má vlastní AV1 dekodér [Stalo se] - 5. Říjen 2019 - 23:00
[4 minuty čtení] Vyšel MX Linux 19 Beta 3, vyšlo FreeBSD 12.1-BETA3, AMD je na vzestupu i v enterprise segmentu a možná chystá Zen 3 s 4×SMT, TSMC rozjede 5nm proces v březnu. Tým projektu FreeBSD pozvolna finišuje práce na prvním aktualizačním vydání v rámci nejnovější řady 12. Čekat tak sice nemůžeme převratné novinky, ale „jedničkové“ aktualizace jsou typicky tím, na co mnozí admini čekají – vychytané chyby a pár drobností navíc. Zde dochází k několika opravám, jejichž stabilitu je možno v rámci třetí beta verze testovat.
