$ phoronix-test-suite benchmark ramspeed
RAMspeed tests the system memory (RAM) performance. With the exception of the N100 mini PC, all the machines are running dual-channel memory.
RAMspeed exposes a clear limitation of the PELADN WO4 review unit. The machine is supplied with a single-channel DDR4 memory configuration, and that severely restricts memory bandwidth. In both the SMP Floating Point and SMP Integer tests, the WO4 sits at the bottom of the chart, even slightly behind the Intel N100 system. That result needs context: the N100 machine is also single-channel, but it uses DDR5, whereas the WO4 uses DDR4.
The Ryzen 5 5600H is a much faster processor than the N100, but here it’s being held back by memory bandwidth. A second RAM module would enable dual-channel operation and should make a noticeable difference in memory-sensitive workloads, as well as integrated graphics performance.
The other systems in the comparison are running in dual-channel mode, which gives them a substantial bandwidth advantage.

This benchmark also tests the system memory performance. memcpy() copies a block of memory from one location to another. memset() fills a block of memory with a specified byte value.
The takeaway is simple: the WO4’s supplied memory configuration is the limiting factor. Adding a second DDR4 module to enable dual-channel operation will noticeably improve memory bandwidth and help the integrated GPU a little too.
