    Baytrail: Intel's Basket case chip

    Intel is producing Baytrial because it likes to finish projects that it has started, but the indication from the Surface Pro launch is clear -- they would rather sell high priced Core series Haswells into tablets than cheap Baytrails. There's no other way they're maintaining ASPs with the continuing growth in the tablet market. Secondly, when compared with core series laptops, a Baytrail based tablet would suck at running legacy apps. Intel doesn't ever want to put out an under-performing solution with their chips.

    At this point Intel's claims that heavily tweaked idle power will result in a major average power draw reduction will have to be tested in the market. Too bad they couldn't accelerate their deployment of 14nm for Haswell.

    • "the Surface Pro launch is clear -- they would rather sell high priced Core series Haswells into tablets than cheap Baytrails."

      Intel would "rather" but they will sell what the customer wants. ASUS is building a Lexington based "Fonepad". Intel will not maintain ASP at their current levels but that will not slow them from selling a lower cost part into a socket at a lower price. Hitting a specific product "ASP" is not the Intel goal. They will have to sell more chips at a lower ASP to make up for any cannibalization.

      "Secondly, when compared with core series laptops, a Baytrail based tablet would suck at running legacy apps. Intel doesn't ever want to put out an under-performing solution with their chips."

      When compared to core series, you are right, Baytrail would underperform in comparison. ASUS is smart enough to know how their system will perform and will target it for the market they want. Their name is on the front too. IMO, I am not sure what legacy app would not perform quite fine on a system configured with a Baytrail.

      "At this point Intel's claims that heavily tweaked idle power will result in a major average power draw reduction will have to be tested in the market."

      The recent detailed power measurements on Atom vs ARM had me scratching my head. ARM had a lower IDLE draw but the ATOM seemed to have a lower EXECUTION draw.

      I think it is due to the onchip ATOM cache memory. The ATOM has to maintain coherrency of the cache even when idling but has a lower miss rate (accesses memory less) than ARM. When you access external memory, it takes larger buffer transistors to drive the address and data lines lines. When running an application, ARM has to access external memory more and burns more power than the ATOM because ATOM memory references are satisfied by cache hits. When idling, ATOM has to power the cache.

      Intel CPU designs in the future (maybe except server chips) will have an onchip voltage regulator that will allow them to lower the voltage (reduces power consumption) or completely power down chip sections.

      "Too bad they couldn't accelerate their deployment of 14nm for Haswell."
      A 22nm Haswell with its redesigned power distribution system will be fine. Intel release 14nm midyear with Haswell but it is more likely they will stay on schedule and move 14nm into productions this year but not with Haswell as a lead product.

      • If there was no Haswell in the picture then I agree Intel would provide what the customer wanted. But with Haswell in the running for tablet and with a $200+ ASP, selling any Baytrail based systems would cannibalize Haswell sales. Why would they want any of that? They would put all their marketing muscle behind Haswell and not Baytrail for tablets.

        If what you say about idle power is true, then Haswell should start approaching the power dissipation point suitable for acceptable tablet battery life. I'm somewhat skeptical about Intel's idle power theory.

    • Baytrail will keep ARM at bay. It does things better than any ARM chip.
