Studying that headline, you are in all probability already considering: “5.2 GHz? Is not {that a} decrease pace than earlier leaks?” Sure, it completely is, however there is a cause for it: the leaker is evaluating the CPU immediately in opposition to Intel’s previous-generation Alder Lake Core i9-12900K at that very same clock fee.
Regardless of utilizing the identical Phanteks Glacier One 360-mm AIO liquid cooler for the 2 CPUs and the Raptor Lake chip having a further 8 cores, the unreleased processor attracts practically 100 much less watts underneath the AIDA64 stress take a look at whereas each chips are restricted to 4.9 GHz.
This disparity roughly balances out when each chips are overclocked to five.2 GHz throughout their P-cores, though the Raptor Lake half remains to be drawing much less energy per core—and staying cooler whereas doing it, too. This may very well be attributable to the AIDA64 stress take a look at not working correctly on the pre-release processor, as a result of the following take a look at offers us the sort of end result we’re anticipating:
Certainly, Prime95 pushes the Raptor Lake chip to its limits, with an total energy draw of 377.9 watts at 1.34 volts. Even underneath a humongous 360-mm radiator, some the CPU’s cores are pushing 92°C.
EJ {Hardware} examined the chip underneath CPU-Z and Cinebench, in fact, and got here away with unsurprising outcomes just about equivalent single-threaded efficiency to the Twelfth-gen half, and drastically improved multi-threaded efficiency due to its additional CPU cores. We do see barely decrease single-threaded efficiency when the CPU is restricted to 4.9 GHz, however that is as anticipated.
Lastly, the leakers examined some video games. There are clearly some anomalies right here; we suspect that a number of the stranger outcomes—just like the Core i9-13900K shedding in Cyberpunk 2077—are all the way down to problems with EJ {Hardware}’s early CPU, early firmware, or presumably some idiosyncrasy that resulted from the overclocking methodology used.
Raptor Lake is a comparatively modest change from Alder Lake, with the largest modification within the P-cores being the rise in L2 cache capability to 2MB. Alder Lake is already very quick, so it is going to be fascinating to see if the small tweaks made to Raptor Cove together with a mountain of additional clock fee can be sufficient to maintain Intel’s newest forward of AMD’s best.
