AMD
is
releasing
new
BIOS
updates
that
will
boost
performance
for
its
Ryzen
9600X
/
9700X
processors
and
address
some
latency
issues.
The
performance
improvements
and
latency
reductions
arrive
around
a
month
after
disappointing
Zen
5
desktop
CPU
reviews
and
appear
alongside
updates
to
Windows
11
that
include
optimized
AMD-specific
branch
prediction
for
both
Zen
4
and
Zen
5
chips.
CPU
reviewers
have
been
reporting
a
higher-than-expected
core-to-core
latency
across
the
Ryzen
9000-series
of
desktop
processors,
and
now
AMD
has
addressed
this
with
a
new
BIOS
optimization.
The
latest
AMD
updates
for
AM5
motherboards
include
AGESA
PI
1.2.0.2
firmware,
which
AMD
says
will
address
some
“corner
cases”
where
it
takes
two
transactions
to
read
and
write
when
information
is
shared
across
different
parts
of
a
Ryzen
9
9000
processor.
“We’ve
managed
to
cut
the
number
of
transactions
in
half
for
this
use
case,
which
helps
reduce
core-to-core
latency
in
multi-CCD
models,”
says
AMD.
AMD
is
promising
a
10
percent
uplift
on
the
9700X
with
its
new
105-watt
mode.Image:

This
BIOS
update
also
includes
a
new
105-watt
cTDP
option
to
push
the
thermal
design
power
of
the
Ryzen
9600X
and
9700X.
“These
processors
have
been
validated
at
105W
since
their
release,
so
you
won’t
be
pushing
them
beyond
their
design
limits,”
says
AMD.
“This
boost
is
especially
beneficial
for
multithreaded
workloads,
but
you
might
see
some
gains
in
less-threaded
apps
too.”
You’ll
need
to
make
sure
you
have
appropriate
cooling
to
enable
the
105-watt
mode,
but
AMD
says
it
should
result
in
around
10
percent
more
performance
on
the
Ryzen
9600X
and
9700X.
This
new
mode
won’t
void
your
warranty,
either.
AMD
is
also
launching
its
next
round
of
AM5
motherboards
this
week,
with
the
X870
and
X870E
boards
both
available
at
retailers.
You
don’t
need
these
new
boards
for
AMD’s
latest
Ryzen
9000-series
CPUs,
but
they
do
come
with
USB
4.0
as
standard,
and
they
also
include
PCIe
5
Gen
5
on
the
graphics
and
NVMe
sides
that
can
be
used
simultaneously.
There
are
rumors
that
the
upcoming
RTX
5090
will
be
a
PCIe
Gen
5
card,
and
AMD
teases
it’s
“more
important
than
ever
now
that
we
are
on
the
cusp
of
a
new
generation
of
graphics
cards”
to
have
full
PCIe
Gen
5
support.
The
X870
and
X870E
boards
also
include
support
for
higher-clocked
memory.
AMD
has
now
enabled
DDR5-8000
EXPO
support
on
these
new
boards,
which
includes
around
1
to
2ns
of
latency
improvements
over
DDR5-6000.
