Sandra Memory Bandwidth
AIDA64 Memory Performance
Memory performance is as we expect from a single-CCD Zen processor. You get reduced overall memory bandwidth versus the dual-CCD Ryzen 9 chips. You also get the half-speed write performance that is common for the single-CCD Ryzen processors on Zen 2 and Zen 3. The similarities between Zen 2 and Zen 3 are understandable given the use of the same 12nm central IO die.
Memory latency versus Zen 2 continues to show improvement, even with this single-CCD Zen 3 part.
