    I hope that whatever APU is used in the PS5 will find its way to individual mobos too. PS4 has nice graphics performance and now runs Linux, but the low single-thread performance is sufficient only for a gaming console, not PC gaming nor general PC tasks. With Zen in the PS5 APU that should be all fine.
    Why would you want a closed and locked down gaming console for your Linux tasks? (I know it was usually Gentoo that was booting first on the opened consoles, but still, it's a lot of work to get those things open (enough) to run some Linux kernel + userland.) And I am rather certain they won't put the very PS5 chips on normal mobos / sockets. It still is a semi-custom design with a lot of problematic "IP" around, so they'd probably run into problems.
    And aren't the current APUs already fairly good?
    Stop TCPA, stupid software patents and corrupt politicians!

      I think chithanh meant "the same APU power but in a more PC-like platform" with less lockdown.

        On my 2200g and x470 board, with these patches to Mesa 18.2 dev, I'm now recording glmark2 scores of above 3600 for the first time. This is on Mint with 14.7.1. Prior to the patch, the scores were 3500. And with all of the work in this area, about 1 month ago, the scores were around 2800.

        So there have been a lot of improvements. If only the system booted properly more than 50% of the time.

          From the PS4 Linux project's presentation at 33c3, there were a number of quirks to address, firmware needed reverse engineering, and some PC legacy which Linux expected wasn't there. And there was the "southbridge" which was its own can of worms. In principle these problems could be readily solved by AMD and by using something sane as southbridge.

          No. They are acceptable for some games and not for others. Also a couple of games which are just playable on a 2400G on Windows after OC are still unplayable on Linux. Deus Ex:MD for example.

          Raven Ridge raw processing power is somewhere between Xbox One and PS4 (circa 2013), but lacks ESRAM compared to Xbone and GDDR5 compared to PS4.

          If it were exactly the same APU with the Sony-specific parts and lockdown disabled it would be fine.
