Whereas we already know that AMD plans to supply CPUs based mostly on completely different microarchitectures in its Ryzen 7000-series processors for laptops, AMD has kept away from publicly itemizing its Zen 3-based Ryzen 7000-series CPUs. However in a brand new doc overlaying a Spectre Variant 2 vulnerability, it formally talked about its Ryzen 7030-series and Ryzen Professional 7030-series cell processors (by way of @komachi_ensaka).
AMD disclosed again in September that ranging from its Ryzen 7000-series processors for laptops and onwards, it might market CPUs based mostly on completely different microarchitectures inside one household to supply a broader vary of merchandise for numerous efficiency wants and worth ranges. In consequence, the Ryzen 7000 lineup of pocket book processors will embrace fashions based mostly on AMD’s Zen 2, Zen 3, and Zen 4 microarchitectures.
In reality, the corporate already lists entry-level Ryzen 3 7320U and Ryzen 5 7520U processors that includes Zen 2 cores on its web site. The corporate may also provide Zen 3-powered Ryzen 7030-series ‘Rembrandt’ CPUs with Zen 3 and RDNA 2 graphics for midrange laptops. The best-end Dragon Vary and Phoenix APUs will belong to the Ryzen 7040 household and can pack Zen 4 CPU cores in addition to (presumably) RDNA 3-based graphics models.
In the meantime, AMD’s new mannequin quantity scheme for cell CPUs is sort of difficult, making it laborious to guess the efficiency of a processor based mostly solely on issues like belonging to its household, formal positioning, and microarchitecture. As all the time, the easiest way to search out out the efficiency of a selected CPU is to take a look at its unbiased analysis.
As for the Spectre Variant 2-class potential vulnerabilities often known as the CVE-2017-5715 and CVE-2022-23824, it apparently impacts all AMD pre-Zen 4 processors for desktops, laptops, and servers, in accordance with the AMD doc. To mitigate the difficulty, an OS or Hypervisor replace is required.
