FEBRUARY 2021 PCWorld 21- AMD’s “Lucienne” chips were reportedly
designed around AMD’s older Zen 2
architecture, and “Cezanne” around the
more powerful Zen 3 architecture. AMD’s
Ryzen 5000 Mobile series included both,
those rumors said, without distinguishing
one from another (go.pcworld.com/rmz2).
Those leaks were, in fact, mostly accurate.
Three of the new Ryzen 5000 mobile
processors—the Ryzen 7 5000U, the Ryzen 5
5500U, a nd the Ryzen 3 5300U—use the
Zen 2 microarchitecture, according to AMD.
Unfortunately, there’s no marks or acronyms
to distinguish them from the other
processors within the family. As the
benchmarks showed, however, even the
“Zen 2” members of the Ryzen Mobile 5000
Yes, some of the Ryzen Mobile 5000 chips use the older Zen 2 architecture. Does that matter?
series are slightly faster than their Ryzen
Mobile 4000 predecessors. If you’re
interested in avoiding any potential
confusion, however, the answer is simple:
simply buy one of the new Ryzen 5000
H-series processors.
What’s important for AMD is the number
of processors it sells. In this, the company
may have already notched a success,
building upon its design wins in the previous
two generations. AMD said that 150
separate mobile PCs will be built upon the
Ryzen Mobile 5000 family, versus 100 in the
prior generation. In the end, those numbers
indicate that AMD has established itself as a
leading-edge processor supplier in the eyes
of its PC customers.
