Ryzen 9 5950X is slightly faster at 14.3 percent.
Both scores are solid wins, and a clear
advantage for Ryzen 5000, but it’s not the yield
you’d see with 3D modelling tasks. Still, if the
cost is similar or close, we’d take the Ryzen
5000, and that’s all that matters to AMD.

COMPRESSION
PERFORMANCE
Next we move on to compression tests using
the popular 7-Zip app. The first result is 7-Zip
19.00’s performance compression test. The
compression side is sensitive to memory
latency, cache performance and out of order
performance. The result is no surprise.
Decompression performance is sensitive to
integer performance, and branch prediction
performance. With this test less reliable on
memory latency and memory bandwidth per
core, we again see that more cores matter. The
16-core Ryzen 9 5950X opens up a huge lead
over the 12-core Zen 3 chip.
We’ll close off our 7-Zip section with

single-threaded results, which favor AMD’s

chips again. We don’t need to show you the

decompress single-threaded performance,

because it’s the same, with AMD running

over Intel.

So far nothing—nothing—has put the Intel

Core i9 in front of the Zen 3 chips.

Nevertheless, we were surprised when the

Intel chip lost WinRAR’s built-in benchmark

using all of the cores. The test itself doesn’t

use every single thread, but it has long run

horribly on AMD CPUs--the 10-core Core i9

has a 15 percent advantage over the 12-core
