AMD's New 12nm Ryzen Laptop Chips Look To Put the Pressure on Intel (theverge.com)

Posted by ryuzaki0 on from the competition-heating-up dept.

AMD has been pushing its Ryzen lineup of processors for a few years now, with the company looking to put pressure on Intel's seemingly unbeatable hold on the chip landscape. From a report: At CES 2019, AMD unveiled its second generation of Ryzen laptop chips, which look to jump ahead of Intel's 14nm roadblock to offer some of the first 12nm processors on the market. To that end, AMD is launching a new lineup of Ryzen 3, Ryzen 5, and Ryzen 7 chips across both the 15W U-series and 35W H-series lineups, almost all of which are built off of the company's new 12nm Zen+ architecture. For the more powerful H-series, there are a pair of new chips: the Ryzen 7 3750H, offering four cores / eight threads, a base clock speed of 2.3 GHz (which can boost to 4.0 GHz), and the Ryzen 5 3550H, also a four core / eight thread processor, but with a 2.1 GHz base speed (which can boost to 3.7 GHz), and only eight GPU cores to the Ryzen 7 3750H's ten.

  1. Zen 1.0 by Artem+S.+Tashkinov · · Score: 4, Informative

    Mind that these mobile CPUs are first generation Zen (which is kinda confusing because people expected 3XXX to belong to Zen 2.0).

      No, the 3000 series APUs are Zen+, the second generation, same as Ryzen 2700 etc. Zen 2, the 3000 series non-APUs are third generation Zen. I know, it's confusing. Just remember, the new APUs are 12nm, with modest IPC and clock speed improvements vs first generation Zen.

  2. Re:Meltdown, Spectre, etc by laffer1 · · Score: 4, Informative

    Meltdown was never a problem on any AMD CPU. That's Intel.

    Spectre affects Intel, AMD, Power, and even some ARM designs. It's unclear what mitigations AMD may have added but since these are based on Zen+ rather than Zen 2, it's likely the same as the more recent desktop chips (Ryzen 7 2700 and so on )

  3. Try selling CPUs without built in back doors. by Ungrounded+Lightning · · Score: 3, Informative

    Intel has Management Engine - a total-control backdoor that's already been broken.

    AMD has ASP/PSP. It's claimed to be less of an issue. But as long as it's closed we can't audit it and thus must assume that it IS an issue.

    A plague on both their houses.
