suspect would run faster on the Ryzen 9 if we
only had a faster GPU. That in itself is insane,
because our card is the $1,200 GeForce RTX
2080 Ti, but there are definitely faster
graphics cards out today—we just didn’t have
access to any for our testing.
If it doesn’t seem like a big deal to be
basically slightly faster to about the same as the
Core i9, you have to remember that AMD
hasn’t beaten Intel in gaming ever. It’s a huge
accomplishment for the company. Like single-
threaded performance victories in productivity
applications, Ryzen 9 basically does everything
Core i9 can do—except it can do it better.
CPU THREADSCALING
Before we reach our conclusion, we do want
to look at how well the new Ryzens scale
across their cores, because software doesn’t
always run on a single core or all cores. For
that we use Cinebench R15 and run it from
one thread to the maximum threads available
