    Is it worth staying with a slightly older CPU for 18.04 LTS?

    My days of distro hopping and upgrading the point release every 6 months is over as i only browse the web and watch media so unless Ubuntu moves to a rolling release i've decided just to stick with the latest LTS from now on.

    I've just started looking at parts for a Coffee lake machine but as LTS uses an older Kernel and backports and patches can take ages (sometimes years) i wondered if it would be best to stay with slightly older hardware like Haswell or Skylake?

    Maybe this thread would be better in either the Hardware or the General Help section........

    Could a Mod move it please?

    Thanks

    Moved to hardware, but since not specific may be better in discussion.

    I have both a Haswell & Skylake systems. With the Skylake I built it in Feb 2016, but had to install 16.04 before released to have it work. And that worked well.

    But Phoronix often uses ppa to install newest kernel & support software.

    Thanks oldfred , I think you're right that it would be best as a general discussion as it's not a specific problem.

    Thank you all so for taking the time to post up all those links and information , i'll be using a Nvidia card so the intel graphics shouldn't be a problem.

    There is lots of older hardware that still isn't well supported. I think it's probably more important to look closely at all the components (chipsets) in a new system to see what driver support will be like.

    If you want good Linux support, sticking with Linux-friendly vendors (Intel for ethernet, Atheros for wifi, nvidia for graphics) helps a lot both with new-ish hardware and over the long term.

    I've changed the topic as it was misleading with the term Hardware , I meant staying with an older CPU for the older Kernel of LTS , oldfred knew what i meant.

    Sorry about that.

    The big takeaway from the Phoronix review is that the CPU worked fine in Ubuntu 17.10. I wouldn't worry about using a Coffeelake CPU in 18.04, especially if you're not using the iGPU.

    I think it's probably more important to look closely at all the components (chipsets) in a new system to see what driver support will be like.
    +1 to that

    Thanks all for the feedback.

    I wish Ubuntu would move over to a rolling format rather than the current LTS and point release.
