FEBRUARY 2020 PCWorld 13versions in thin and
light laptops and
“H-class” 45-watt
gaming and content
creation laptops.
The Ryzen 7
4800U is the top-end
low power version,
packing 8-cores and
16-threads. It will hit
boost clock of
4.2GHz and have a
base clock of 1.8GHz. The chip will feature
eight compute units in its Radeon graphics
cores, which—surprisingly—use an optimized
version of the company’s 7nm Vega cores
rather than being based on the company’s
newest RDNA architecture.
AMD said a Ryzen 7 with 8 compute units
actually outperforms its previous Ryzen 7
3000 mobile chips, which had 11 compute
units. The newer Ryzen 7 4000’s graphics
cores actually offer 59 percent more
performance per
compute unit over
the older Ryzen 7
3000 offerings, the
company stated.
AMD isn’t aiming at
older Ryzen 7 3000
though. It’s finally
hoping to dethrone
Intel’s mobile chips, and
if what AMD claims is
true, it’s happening.
AMD said the Ryzen 7 4800U, for
example, will offer about a 4 percent
advantage over Intel’s most advanced
10nm-based Ice Lake Core i7-1065G7 in
single-threaded performance. But single-
threaded performance is just part of it.RYZEN 7 HAS MORE CORES
As Intel’s “Ice Lake” 10th-gen Core chip tops
out at four cores, it’s no surprise that the
