Intel may be launching its enthusiast-segment desktop processor, the Core i9-14900KS Special Edition next week, but the chip is already in the hands of several elite overclockers, such as Pakhtunov from OCN. Once he got his hands on one of these, Pakhtunov wasted little time in de-lidding the chip, cleaning it up, grabbing some pics, before throwing it back in the arena for some before-and-after comparisons.

With its stock integrated heatspreader (IHS) in place, a Cinebench 2024 load sees a boost frequency on the P-cores of 5.90 GHz, in which the processor draws a staggering 376 W (as reported by the motherboard's ACPI to software); and a temperature of 85°C, when cooled with a Deepcool LS720 SE 360 mm AIO CLC. With the IHS removed, and at the same 5.90 GHz clocks and Cinebench 2024 load, sees the temperatures drop to 75°C, and power-draw to 366 W. The story repeats with the more brutal Y-cruncher stress test. The original chip with the IHS in place, and a 5.90 GHz boost on the P-cores, pulls a staggering 432 W, and 89°C temperatures. Remove the IHS, and the temperature drops to 82°C, with 409 W package power. It's worth noting here, that with the IHS removed, Pakhtunov used a liquid-metal TIM application between the die and the cold-plate.

Stock at 5.9 GHz with 432 W on an AIO yet only reaching 89°C is nuts.

These are going to be fun chips for tuning delidded with custom watercooling.

Swansong of monolithic, wonder if 6.4 GHz+ all core is possible, maybe with E cores disabled.

Obviously arrow-S is also monolithic. Shrunk from 10nm to 5nm whatevers that entails as density doubled 10nm to 7 is 2X, and another 50% to 5 nm. 257mm2 to 100mm2. Why do anything else why do foveros package on a desktop and under the IHS such a non sense

Intel 7 is not a 10 nm process. The gain from Intel 7 to 4 won't decrease die size by as much as you think. At best, you would get a reduction of 2x for logic, but SRAM sees scaling between 0.77 and 0.81. A significant portion of these processors is made up of SRAM so actual scaling wouldn't even be 2x. Assuming a typical 33% of area devoted to SRAM in the Intel 7 products, the die won't be less than 150 mm^2 in Intel 4. In all likelihood, it would be even larger as some of the density gains would be used to increase transistor counts.

By the way, how far have overclockers been able to push E cores alone, with P cores idle? I'm sure somebody's gonna try that with this KS chip too.

It's not.

Multiple dies combined on foveros packaging.

Did he lap the die as well? It looks like the middle has been flattened out a little bit. Either that or the camera lens reflection.

While this is an absolutely ridiculous product in almost every way, and doesn't make sense in 99.999% of scenarios, I will admit this thing would probably be incredibly fun to tune and try and squeeze every last drop of performance out of. Godspeed Intel, y'all got some big ol' balls releasing this thing into the wild.

Was Intel on some sort of bet for how much they can slapdash that product lol?

It's nice that Intel and AMD are now both better in their own ways. A younger me would definitely buy this and spend months tuning and benching it, even though a 7800X3D would be better for my use case at a lower price and a quarter of the power draw. We'll come to miss chips like this.

Don't think 6.2 all core will be possible, but that VID does seem crazy good to me.

And you mean AMD goes the the opposite way? Hmmm. Maybe Guru3d editor screwed up the chart. Who knows:D
