8 PCWorld JULY 2019NEWS AMD RYZEN 9 3950X
But its arrival means that AMD has fully
fleshed out its lineup that will take on Intel’s
9th-gen chips.WHAT MAKES RYZEN
3000 SO MUCH FASTER?
Ryzen 3000’s performance increases don’t
seem to come from just one single aspect,
but an accumulation of changes between theRyzen 3000 series and
older Ryzen 2000 chips.
Obviously, one of
the big advances is the
process shrink from
Ryzen 2000’s 12nm to
Ryzen 3000’s 7nm.
AMD officials said
process shrinks typically
increase wire resistance,
as the wires literally get
smaller. But the
company has
successfully gone
against that and actually
increased clock
frequencies generation
to generation.
The smaller process
yields sizable power
efficiency increases,
too. For example, AMD
said a Ryzen 7 3700X
offers 75 percent more
performance than a
Ryzen 2700X in Cinebench R20 multi-
threaded tests. During that test, the Ryzen 7
3700X consumes 135 watts at the wall, while
the Ryzen 7 2700X demands 195 watts.
When companies move to a completely
new process technology, they usually keep
other aspects of the chips intact. In the move
from 12nm to 7nm process, however, AMD
took the additional step of redesigning the xIt’s finally here! AMD’s Ryzen 9 3950X features 16-cores and 72MB of
cache, and is built on a 7nm process.Here are the chips AMD will put up for sale on July 7.
