DDR5 memory makes Intel Raptor Lake CPUs at least 11% faster in Geekbench

Intel Raptor Lake gets DDR5 boost

Two Intel Raptor Lake CPUs have now been tested with DDR5 and DDR4 memory. 

A fresh Core i7-13700K 16-core CPU score is now available on Geekbench website, this time, however with DDR5 memory. The processor has now been tested with two nearly identical motherboards: ASRock Z690 Steel Legend WiFi 6E (story here) and ASRock Z690 Steel Legend WiFi 6E/D5, the only difference being the supported memory.

According to the listing, the new score was achieved with 32GB of DDR5-5200 memory while the previous score featured DDR4-3600. Such a change alone provided nearly 20% improvement in multi-core Geekbench score, but also marginally lower single-core performance.

Interestingly, a very similar leak surfaced just 2 days ago, featuring 14-core Core i5-13600K CPU. Here, unfortunately, memory specs were not listed, but we do know that both tested platforms featured either DDR5 or DDR4 memory. And again, the DDR5 system was faster, although only by 11%.

Both leak show the importance of DDR5 memory for synthetic and all memory-bound tests. We are yet to see how does synthetic benchmark difference stacks up with gaming performance though.

The flagship 24-core i9-13900K has already been tested with DDR5 memory, and it now occupies the top of the Geekbench ranking. All three K-Series SKUs will be part of the September reveal and October launch with more parts coming around January next year.
