Zen 3 is coming to the Ryzen Mobile 7000 series.
While it is already known that AMD will offer Ryzen 7000-series processors for laptops with different microarchitectures, AMD has refrained from publicly listing its Zen 3-based Ryzen 7000-series processors. However, in a new document covering the Spectre Variant 2 flaw, AMD formally acknowledged its Ryzen 7030-series and Ryzen Pro 7030-series mobile processors (via @komachi ensaka).
AMD announced in September that beginning with its Ryzen 7000-series processors for laptops and moving forward, it would market CPUs based on different microarchitectures within a single family to offer a broader selection of products to meet a variety of performance and price requirements. Consequently, the Ryzen 7000 family of notebook processors will include models based on Zen 2, Zen 3, and Zen 4 microarchitectures.
The company’s website already features entry-level Ryzen 3 7320U and Ryzen 5 7520U processors with Zen 2 cores. In addition, the company will offer Ryzen 7030-series ‘Rembrandt’ processors with Zen 3 and RDNA 2 graphics for midrange laptops. The most powerful Dragon Range and Phoenix APUs will be a part of the Ryzen 7040 family and feature Zen 4 CPU cores and (presumably) RDNA 3-based graphics units.
Meanwhile, AMD’s new model number scheme for mobile CPUs is quite complex, making it difficult to predict a processor’s performance based solely on its family membership, formal positioning, and microarchitecture. The best way to determine the performance of a specific CPU is to consult its independent evaluation.
According to the AMD document, the Spectre Variant 2-class potential vulnerabilities known as CVE-2017-5715 and CVE-2022-23824 affect all AMD pre-Zen 4 processors for desktops, laptops, and servers. An operating system or hypervisor update is required to mitigate the issue.
