  • This is kinda old information, but my understanding was that there were 3 issues with dasiy-chained UPSes.

    The first is that you’re potentially going to cause a ground loop, which is not healthy for the life of anything plugged into those UPSes.

    The second is that there’s a potential for a voltage droop going through from the first to second UPS, which means the UPSes will flap constantly and screw their batteries up, though I’d be shocked if that was necessarily still true for modern high-quality units.

    And of course, the UPS itself won’t be outputting a proper sinewave when it’s on battery, which means your 2nd UPS in the chain will freak out (though again, maybe modern ones don’t have that limitation).






  • That’s a wee revisionist: Zen/Zen+/Zen2 were not especially performant and Intel still ran circles around them with Coffee Lake chips, though in fairness that was probably because Zen forced them to stuff more cores on them.

    Zen3 and newer, though, yeah, Intel has been firmly in 2nd place or 1st place with asterisks.

    But the last 18 months has them fucking up in such a way that if you told me that they were doing it on purpose, I wouldn’t really doubt it.

    It’s not so much failing to execute well-conceived plans as it was shipping meltingly hot, sub-par performing chips that turned out to self-immolate, combined with also giving up on being their own fab, and THEN torching the relationship with TSMC before you launched your first products they’re fabbing.

    You could write the story as a malicious evil CEO wanting to destroy the company and it’d read much the same as what’s actually happening (not that I think Patty G is doing that, mind you) right now.


  • Yeah but it’s priced the same as a cheap laptop and/or desktop, which of course doesn’t then require you to pay monthly to actually use the stupid thing.

    It feels like another ‘Microsoft asked Microsoft what Microsoft management would buy, and came up with this’ product, and less one that actually has a substantial market, especially when you’re trying to sell a $350 box that costs you $x a month to actually use as a ‘business solution’.

    This would probably be a cool product at $0 with-a-required-contract-with-Azure, but at $350… meh, I suspect it’s a hard sale given the VDI stuff on Azure isn’t cheap.



  • Yeah, it doesn’t appear that PSSR (which I cannot help but pronounce with an added i) is the highest quality upscaling out there, combined with console gamers not having experienced FSR/FSR2/FSR3’s uh, specialness is leading to people being confused why their faster console looks worse.

    Hopefully Sony does something about the less than stellar quality in a PSSR2 or something relatively quickly, or they’re going to burn a lot of goodwill around the whole concept, much like how FSR is pretty much considered pretty trash by PC gamers.



  • really effects performance that much

    Depending on the exact flags, some workloads will be faster, some will be identical, and some will be slower. Compilier optimization is some dark magic that relies on a ton of factors, but you can’t just assume that going from like -O2 to -O3 will provide better performance, since the optimizations also rely on the underlying code as to what they’ll actually make happen… and is why, for the most part, everyone suggests you stop at -O2 since you can start getting unexpected behavior the further up the curve you go.

    And we’re talking low single digit performance improvements at best, not anything that anyone who is doing anything that’s not running benchmarks 24/7 would ever even notice in real world performance.

    Disclaimer: there are workloads that are going to show different performance uplifts, but we’re talking Firefox and KDE and games here, per the OP’s comments.

    Also they do default to a different scheduler, which is almost certainly why anyone using it will notice it feels “faster”, but it’s mainlined in the kernel so it’s not like you can’t use that anywhere else.
