    Very interesting. Have speculated on that for a while. It'll be interesting to see.

    Will they drop 32bit from the big cores and leave it on the little?
    Atom cores for little?

    And how will AMD respond?

    Dig out the original Athlon64 core? Build a new one?

    Where'd you hear these rumors?

    I read a rumor that they were going to pack in:
    - two DDR4 channels, each supporting up to DDR4-2933 for up to 45.8GB/s aggregate bandwidth
    - 16 lanes of PCIe3.0,
    - 4/6/8 core options with turbo speeds up to 5.1GHz
    - 14nm Lithography
    - 125W TDP
    - LGA1700 socket

    big.little is a total waste of time for Desktop.

    I suspect they might use it to retain x86 compatibility once windows' kernel is fixed to cope with big.little better.

    Then they can streamline the x64 core and keep a few atoms around to deal with the bullshit.

    Pretty spot on for a June 2020 Guess mate :thumbup:

    I intend on upgrading to Adler lake myself, still on the trusty 7700K till then.

    I heard Intel's gonna ditch 7nm and go straight to 3-5nm after 10nm.

    Not according to their earnings call

    Wonder if it's worth waiting to upgrade the wife's PC...
    and HOW long i have to wait...

    No its not, the majority of CPU sales for Intel is still in that 10400 / 10500 / 10700 range that go into the millions of pre-built HP / Dell / Lenovo desktops. Having a a few energy efficient low performance cores to handle basic browsing and outlook duties and some high performance cores for when they work load actually needs it makes sense.

    Well, no it doesn't make sense because the power consumption differences between running Big.Little setup vs just a lower number of high performance cores run into, lets say "negligible territory" for that use case scenario. Beneficial for Mobile, and ultra-portable, where even a 1 Watt saving is a lot for improving battery life during mundane tasks, but something you plug into a wall.. Nah. Not worth the peak performance sacrifice where limited by max practical scaling of desktop workoads (i.e, you can't just throw 20 little cores on there to counteract their lack performance) , nor the Scheduling complexity / headaches.

    Further to that, if Intel's 'high performance' cores weren't so fundamentally power hungry and huge, there would be even less of a need.. This is something they are really not good at currently, which somewhat explains the motivation to go down this path. Especially with the Atom Design's actually achieving good perf/watt

    The assumption on power consumption on Intel performance cores is largely based on a rapidly aging process that is reaching its natural end of life. The back porting of the 11th gen design to 14nm process should not be used as a yard stick on future efficiency gains. Intel themselves seems pretty optimistic of there 10nm Superfin process. The Tiger Lake / Ice Lake mobiles cores on the 10nm process are showing decent gains in efficiency.

    Well I'm no talking about 14nm, I'm referencing Tigerlake 10nm SF. It's still not efficient, and it's still a large core compared to, well everything in it's performance realm.. Zen 3, even M1 if you scaled it up to 7nm.

    That's what is says . 8 P ,(performance) +8 E ( Efficiency )
