Rumors: On some 700-series motherboards, Intel is said to enable a 350 W power limit for the i9-13900K Raptor Lake CPUs. The Intel i9-13900K may consume as much power as the RTX 3080 Ti GPU from Nvidia. (Photo credit: VNReview) The Intel i9-13900K could consume as much power as the RTX 3080 Ti GPU from Nvidia. (Photo credit: VNReview) The 350 W PL mode may be easily accessed through a BIOS setting, but in addition to the high-end Intel 700-series motherboard, efficient CPU running also necessitates better cooling and, maybe, a more potent PSU.
A few weeks ago, we were reporting on an Intel Raptor Lake i9-13900K qualification sample that had its PL1 and PL2 unlocked manually to accept power loads of up to 4095.9 W and this maneuver essentially boosted the TDP to 345 W, which is around 100 W higher than the nominal PL2. A more recent report coming from Hungarian publication ProHardver suggests that this PL override is actually a feature easily accessible on the upcoming Intel 700 series motherboards. It looks like Nvidia and now Intel are going to ignore all the climate change concerns advocating for optimized power consumption just to get ahead of AMD.
Tests performed on the aforementioned i9-13900K qualification sample running at 345 W showed only 15% gains in multi-thread loads over samples running in 253 W PL2 mode. Not exactly worth the additional 100 W plus the costs of a new cooling system, new premium motherboard and eventually a new PSU, but, depending on how Intel polishes things for the rumored October launch, final Raptor Lake CPU versions could show better results.
