Intel Core i9-13900KS Could be World's First 6 GHz Processor
With Intel's 13th Gen Core "Raptor Lake" facing stiff competition from AMD's Ryzen 7000 series, and the "Zen 4" series being augmented with 7000X3D series in early-2023, it's becoming a foregone conclusion that Intel will launch a possible "Core i9-13900KS" SKU, which is on its way to being the world's first desktop processor that can boost up to the 6.00 GHz mark. The processor should be able to boost its 8 "Raptor Cove" P-cores to the 6.00 GHz mark, given that the maximum boost frequency of the stock i9-13900K is already rumored to be at 5.70 GHz.
At its Tech Tour event in Israel, Intel confirmed that "Raptor Lake" brings a 15% single-threaded, and 41% multi-threaded performance gain over "Alder Lake." The single-threaded gain is from the higher IPC of the "Raptor Cove" P-core, coupled with its frequency set as high as 5.70 GHz; whereas the multi-threaded performance gain is a combination of increased IPC of the P-cores, and increased frequencies for both the P-cores and E-cores. The E-core clusters get more shared L2 cache, which should improve their performance, too.

Did they actually looked up the OC WR ?
Btw, That 'Ghz' is a terrible mistake if it is an official Intel PPT
Anyway. Unnecessary move, considering they will have the opportunity to advertise the maximum number of cores on the mainstream market. But it will help them to get on the top spots on benchmark charts, making people think that Intel's CPUs are the most advanced.
To be fair this does not look promising.
A '6GHz first' can definitely do PR work very well.
For example, on my Ryzen 9 5900X, it should be 3.7 GHz, but CPU-Z reports 3.599 GHz as the lowest, while the Task Manager 3.8 GHz as the lowest but most of the time around 4.0 GHz.
And even that is wrong reporting because the CPU must idle at much lower clock.
For the people who are happy with "just" 5.8ghz, i'm sure that will be doable on a single core within around 250 w.
Anyway, let's wait and see what happens before jumping to conclusions.
The most power hungry GPUs were 350-400w with >600mm^2 die
There's also TEC coolers which Intel has recently pushed. Just an engineering/design challenge really. CPU's aren't going to change anytime soon in their die sizes compared to GPUs, and the bleeding edge of performance will always cost that exponential bit more.
CPU micro-architectures have different designs which define the frequency potential and ceilings.
It might be that the intel micro-architecture has more pipeline stages.
I don't think there is a problem to clock a 45 nm chip up to 7 GHz. AMD Phenom II Processor is Overclocked to 6.93 GHz | WIRED
Or a 32 nm Bulldozer up to 8.4 GHz. AMD overclocks Bulldozer to 8.429GHz | bit-tech.net
