If nothing else, the 7-Zip benchmark makes for an fascinating check. That is each as a result of it’s a sensible benchmark (quite than an artificial check) and likewise as a result of it reveals uncommon efficiency conduct. Common leaker Raichu (@OneRaichu on Twitter) is coming at us once more with one other pre-release Raptor Lake leak of, you guessed it, the 7-Zip benchmark.
7-Zip’s venerable benchmark utility received a big step-up with the v22 launch of the open-source archiver. Whereas it would not really look any fancier, the no-nonsense check now presents its information in a extra related format for contemporary programs, and it additionally features a modicum of monitoring information as properly. It is this model that Raichu used for his personal testing on each a pre-release Core i9-13900K in addition to a Twelfth-gen Core i9-12900K.
You’ll be able to see these two outcomes above and beneath. Should you pore over the numbers, take into account that the Raptor Lake half is rocking not solely the next clock charge—seen within the monitoring information on the suitable facet—but additionally eight extra Gracemont E-cores.
The positive aspects in compression duties aren’t that nice—in truth, the Raptor Lake half really performs worse on a per-core foundation, for some cause—however the decompression efficiency is phenomenal, outstripping the older Alder Lake machine by practically 60% on common throughout the ten benchmark runs.
For extra perspective, we additionally in contrast the end result to a Ryzen 7 5800X3D chip. 7-Zip is understood to love huge CPU caches and the Ryzen structure, so the spectacular displaying right here (by way of per-core efficiency) is not shocking. In fact, the massively multi-core Intel chips far outstrip the overall efficiency of the 3D V-Cache Ryzen and its puny 8 cores.
The huge enchancment in per-core decompression efficiency is probably going largely because of the elevated L2 cache measurement in Raptor Lake. Whereas the upcoming chips aren’t anticipated to have huge architectural adjustments, each P-cores and E-cores are seeing elevated cache sizes and clock charges.
These easy adjustments alone ought to add as much as vital efficiency enhancements in most purposes, at the very least for the desktop Raptor Lake CPUs. In fact, the extra E-cores will assist in multi-threaded duties, too. We’ll discover out simply how a lot distinction the adjustments make when these elements hit the market, which could possibly be in late September.
