16 PCWorld FEBRUARY 2020NEWS AMD’S 7NM RYZEN 4000 LAPTOP CPUS
4800H with a boost clock of 4.2GHz and
base clock of 2.9GHz, and a 6-core,
12-thread Ryzen 5 4600H with a boost clock
of 4GHz and base clock of 3GHz. Both also
feature optimized Vega-based Radeon
graphics cores.
AMD said the Ryzen 7
4800H’s eight cores let it easily
outperform Intel’s Core
i7-9750H by 46 percent in
multi-threaded performance, as
that chip only has six cores.
Single-threaded performance
closes up, but AMD claims it has
about a 5 percent advantage
over the popular Core
i7-9750H. In other performance
tests, AMD said Ryzen 7 4800H
leads Core i7-9750H by 25
percent in Adobe Premiere CC,
32 percent in POV-Ray, and 31
percent in Blender.
Even crazier: AMD said its
laptop Ryzen 7 4800H can
actually outperform Intel’s
desktop Core i7-9700K in
multi-threaded performance.
How? Intel’s Core i7-9700K has
8-cores at fairly high clocks, but
the company doesn’t offer
Hyper-Threading on it. These
Ryzen mobile H-series chips, on
the other hand, do offer
simultaneous multi-threading.There are some indications of just how
impressive Ryzen 4800H might be though.
One of the new laptops is Asus’ ROG
Zephyrus G14 laptop (go.pcworld.com/
