    Default Intel Adds Initial Cherryview Support To Their Linux 3D Driver

    Phoronix: Intel Adds Initial Cherryview Support To Their Linux 3D Driver

    Cherryview Atom SoCs aren't being released for several months but the first bits of hardware enablement have landed within the open-source Mesa 3D Linux graphics driver. Cherryview with the Cherry Trail platform is the next-generation successor to the wonderful Bay Trail hardware...

    what exactly is cherrytrail? willow trail will feature new cores and will be released right after cherrytrail.

    is cherrytrail just a shrinked baytrail to 14nm?

    After some googling it looks like Bay Trail matches up with Silvermont, which is kinda sorta Haswell. So if we work off that...

    Baytrail ---> Haswell
    Cherry Trail ---> Broadwell
    Willow Trail ---> Silverlake


    Tock's like Haswell and Will Trail add in new features and a revamped Architectures. Tick's like Broadwell are a die shrink and a fine tunement of the previous Tock (better performance, slight modifications. But nothing major). If you're looking for an upgrade path I'd recommend Tick's since a Die Shrink normally brings along better temperature and power consumption for a given Tick-Tock cycle.

    EDIT: If someone from Intel could post and either confirm or disprove me, that'd be awesome. Because this is just what I found googling around and trying to Match up SOC Architecture's with Mainstream Architectures.

    Eric, only "Core" branded chips are in the Tick/Tock cycle. The Atoms are officially not. Let me list some Atom vs Core cores.

    Core:
    Ivy Bridge-3rd Gen Core "Tick" 22nm
    Haswell-4th Gen Core "Tock" 22nm
    Broadwell-5th Gen Core "Tick" 14nm
    Skylake-6th(?) Gen Core "Tock" 14nm

    (you are probably confusing Skylake with Silverlake, but the latter does not exist)

    Atom:

    Medfield/Clover Trail: Atom Z2xxx series 32nm
    Silvermont/Bay Trail: Atom Z3xxx series 22nm
    Airmont/Cherry Trail: Atom ???? series 14nm

    Medfield, Clover Trail, Bay Trail, Cherry Trail is a PLATFORM(CPU/chipset and board) code-name while Silvermont and Airmont is the CORE codename. Medfield/Clover Trail uses same cores, and is based off "Silverthorne" core that came back in 2008 with 45nm Atom chips.

    what exactly is cherrytrail? willow trail will feature new cores and will be released right after cherrytrail.

    is cherrytrail just a shrinked baytrail to 14nm?
    Yes, and maybe some small enhancements to the CPU core. The GPU is expected to have a large gain. "Willow Trail" that Eric mentioned is actually platform code-name to the successor of Cherry Trail, and it uses the "Broxton core, still on 14nm process.

    thanks for the clarification, guys. did anyone of you see the leaked roadmap for 2014? according to this slide intel will release willow trail (core codename Goldmont(?)) this year, although we have yet so see cherry trail..

    why would i even look at the die shrink called "cherry trail" when there's a new architecture within "willow trail" a few months later?

    I doubt that its true. If it is though there is probably a good explanation. One I can guess would be that Cherry Trail is for low-mid range devices and Willow Trail for high/very high end, so we'd have a 3-line division of Atom/Atom High end/Core.

    No sane manufacturer releases replacement products a mere quarter after current ones.

    That's not very smart. The "high-end" Atoms will eat into Intel's margins for low-power Celerons and Pentiums.

    No tech manufacturer is immune to resorting to such choices. Not even Apple and Samsung.

    There's of course a caveat though. High-end means higher prices. Also I doubt the leaked "roadmap" is right.

    This Roadmap is nonsense, Intel doesn't use such design for their Roadmaps. If all goes well Broxton comes mid-2015. Cherry Trail is expected for November. So this could end up with a two or three quarters gap between these two.
