AIDA64 memory bandwidth performance is about where we'd expect from a 16GB kit running at 3200MHz. The write speed is perhaps a touch lower than the competition but not by a huge amount.
Similarly, aggregate memory bandwidth in SiSoft Sandra is right between other similarly-specced kits, coming in just shy of the 39GB/s mark.
As for the SSD, we're not 100% sure who the OEM for this drive is, as almost nothing can be found online when searching the model number. Still, it is a PCIe 4.0 drive, with very fast reads at 7GB/s. The writes are a bit slower though, at 4.5GB/s, but for a gaming laptop of this class, I'd say drive performance is more than acceptable.
As for PCMark 10, the Aorus 15 is again competitive. The ROG Flow Z13, with its 12900H, does score a few hundred point more, but as an indicator of overall system performance, we can't complain with this result.
