    RIP intel

    I dunno... ice lake is pretty competitive.

    Are you unable to read basic graphs or something? Ryzen 4000 (Ryzen 7 4800U to be specific) beats the best Ice Lake chip Intel has (i7-1065G7) in literally every single metric (+4% in single-thread, +90% in multi-thread, & +28% in iGPU). Perhaps go back to elementary school lol; it seems you need it more than you might think.

    The only metric that remains is battery life. If Renoir can match Ice Lake on efficiency (specifically idle power draw) then AMD should finally get some premium designs wins.

    It they could match i think they would make a fancy graph about it, but nowhere in the article was battery life mentioned which makes me think it'll still be behind intel.

    I can't buy that with the absolutely INSANE power efficiency advantage 7nm Zen 2 based Ryzen 3000 CPU's have on desktop (nearly 2x vs 14nm CL-R).

    My guess is that it's only a definitive win against the Skylake based machines (aka Coffee Lake Refresh Mobile & Comet Lake Mobile), with 10nm Ice Lake able to put up a MUCH closer (and less flattering) fight. And unless you're winning in a category across the board like they are with the other parameters, perhaps it is best not to bring any direct attention to it at all.

    They don't have a power efficiency advantage on desktop for idle power: the chipset alone wants 11-15W. Most laptops spend most of their time idle; it's the low end of perf AMD needs to demonstrate wins in to be viable in notebooks (except giant gaming monsters with terrible battery life anyway).

    I'm not saying they can't do it, I'm saying they haven't proven that they have done it yet.

    - mobile Ryzen 4000 laptops only support PCIe Gen 3
    - Ryzen APUs have traditionally had 8 fewer PCIe links than regular CPUs; makes sense for mobile use, since it will cut down die area and power consumption
    - on desktop, the I/O dies are manufactured on 12/14 nm nodes and are the same design as the X570 chipset; since the mobile Ryzen is a monolithic 7 nm die, this power consumption should be reduced
    - Ryzen CPUs (even on desktop) are SoCs, with a limited number of integrated SATA and USB controllers, so they don't necessarily need a chipset at all
    - even if a chipset were to be used, it could be much smaller than the desktop X570

    What I'm getting at is that basing power estimates on the vastly different desktop design (with completely different design goals) doesn't help here.

    Source for Ryzen 4000 being PCIe 3.0 only or I call total BS on that one.
  • Hul8 - Monday, January 6, 2020 - link

    @Cooe Simply searching in this article (for "PCIe" or something) would have sufficed.

    Here's the relevant string for you: "It should be noted that for both U-series and H-series, the chips only support PCIe 3.0".
