Sandra Memory Bandwidth

AIDA64 Memory Performance

Memory bandwidth falls right in line with what we expect from Zen 2. The 8-core, single-CCD 3800XT gets the half-speed write bandwidth, as is common for other single-CCD Zen 2 chips.

Latency is also similar to the other Zen 2 chips, unsurprisingly. Intel’s Skylake-based architecture for its mainstream processors still enjoy far superior memory latency behaviour.
