AMD Ryzen 9 7950X & Ryzen 7 7700X ‘Zen 4’ Review

Sandra Memory Bandwidth

AIDA64 Memory Performance

Support for dual-channel DDR5 memory on the new Ryzen 7000 chips provides a significant boost to memory bandwidth scores versus Zen 3 with DDR4.

With that said, Intel’s DDR5-equipped 12^th Gen platform offers consistently higher memory bandwidth in our testing. And the margins in favour of Intel’s setup are actually very wide, despite running at the same DDR5-6000MHz configuration.

As a side-note, it is good to see the half-speed write penalty for single-CCD Zen 3 chips not present on the single-CCD Zen 4 Ryzen 7 7700X.

Despite jumping up to higher-speed, higher-latency DDR5 memory, AMD does a good job to keep actual latency numbers in check. Here, we see values that roughly match Intel’s 12^th Gen platform in its DDR5 configuration.
