Intel Core i9-14900KS Draws as much as 409W at Stock Speeds with Power Limits Unlocked
Intel's upcoming limited edition desktop processor for overclockers and enthusiasts, the Core i9-14900KS, comes with a gargantuan 409 W maximum package power draw at stock speeds with its PL2 power limit unlocked, reports HKEPC, based on an OCCT database result. This was measured under OCCT stress, with all CPU cores saturated, and the PL2 (maximum turbo power) limited set to unlimited/4096 W in the BIOS. The chip allows 56 seconds of maximum turbo power at a stretch, which was measured at 409 W.
The i9-14900KS is a speed-bump over its predecessor, the i9-13900KS. It comes with a maximum P-core boost frequency of 6.20 GHz, which is 200 MHz higher; and a maximum E-core boost frequency of 4.50 GHz, which is a 100 MHz increase over both the i9-13900KS and the mass market i9-14900K. The i9-14900KS comes with a base power value of 150 W, which is the guaranteed minimum amount of power the processor can draw under load (the idle power is much lower). There's no word on when Intel plans to make the i9-14900KS available, it was earlier expected to go on sale in January, along the sidelines of CES.

Each 8-pin EPS is 225 W.
Power limits, temperatures, clocks, voltages and probably some other parameters are all part of what CPU is at stock. If you remove limits they will go beyond limits.
What might be the surprising part here is that 14900K is capable of scaling beyond the already high stock power limit. Would not expect it to scale well in performance at that range though.
I don't really think I was expecting anything else...but there's got to be almost no room for overclocking when this is the default performance. That said, who in Hades is this targeted for? It's that joyful halo between truly business workloads that would benefit from their server product...and maybe video editing machines? I'd love to be the fly on the wall trying to justify purchasing this thing just to see how to sell ice cubes to Inuits, or sand in the middle east.
i wonder when they will start using diamond ihs‘s
Slapping an air cooler on any i7 part and up since alder lake screams "should've bought AMD" to me.
I'm more concerned about how fast the heat can transfer away from the CPU itself.
Delidding is in my eyes a requirement to get your money's worth and even that is very debatable.
But hey, e-peen.
Mother of god
I'll stick with i7.
400W consumption is really nothing. Server boards have roughly just 4 VRM's powering CPU's with 400W easily.
But this is quite stupid. AMD was flamed, burned for releasing a 220W FX Chip that would run up to 5Ghz and was a world class OC'er. Now intel is in the same boat. releasing 410W CPU's (at most worst conditions). Cooling a chip like that in such density is almost impossible.
Call it
Above 3.2 GHz they're less power efficient than the P cores which make up for their higher power draw with speed in race to idle.
These chips also have per core OC, so you can get significant efficiency gains by setting only a few cores to max boost, and having the rest in their sweetspot without losing any single or lightly threaded performance.
You don't have to run these at balls to the wall settings to still have an extremely fast CPU. Basically just a 14900K with a guaranteed 6.2 OC.
1. High clock speeds and power consumption of Netburst (p-cores)
2. Low clock speeds and IPC of Atom (e-cores)
3. Iffy core/thread counting of Bulldozer (hybrid cores and dropping HT)
Yeah, I think I’ll pass on a Netbursty, Atomic Bulldozer.
:peace:
Tired of people assuming tuning the top tier chip is stupid or somehow worse than buying a lower tier bin that's slower in all respects. A higher bin will tune better even at the same power limits.
