Pyprime 2.0 2b
Let’s now move on to the synthetic benchmarks, which we will only use in our upcoming RAM tests. Pyprime 2.0 from Monabuntur is actually a benchmark for competitive overclocking, but it is also well suited for comparing working memory kits. The software is also completely open-source, based on Python and integrated into the Benchmate Launcher, which makes it easier to use.
I have already put a tested DDR5 “Kit X” in the diagrams, anonymized so as not to spoil the review, to get a feeling for the ranking. Since Pyprime almost exclusively emphasizes low latency, the DDR4 kit is at the top in XMP and OC. After that, the XMP kits follow in the order you could already deduce from the kits’ data sheet – higher clock rate and tight timings on top, low clock rate and loose timings on the bottom.
For the overclocked configs, the order is also relatively predictable, but all kits make a significant jump in benchmark time with manual optimization. Our anonymous test Kit X slips a bit to the back – I wonder what kind of kit it could be? 😀
y-cruncher 2.5b
The y-cruncher is also integrated into Benchmate and is also open-source, but prefers almost the complete opposite for RAM, namely bandwidth. Accordingly, DDR4 has no chance here. However, the distances are not as great as one might expect. This is because, unlike with Pyprime, the CPU cores have to do real hard work here, and supplying them with data ever faster has increasingly smaller relative advantages as the bandwidth increases – keyword “diminishing returns”.
Again, the order is no surprise and can already be seen on the kit sticker in the XMP configs. But especially in manual overclocking, this benchmark is relatively sensitive to subtimings, which explains the Kit X falling behind the Samsung B-Die Kit. I can already spoil: Kit X has Hynix ICs.
