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.

The cooler a chip is, the less voltage is required to run it stably, as a general rule.
Clearly you're running a manually honed setup that's had way more time and thought put in then the average Joe yet. Use your setup as a cludgeon to bait AMD user's with bullshit comments like mine runs fast cool and efficient, perhaps but not without an amount of effort most Won't put in.
Thanks for the clarity, post noted.
I'm finding the better silicone you've got the better off you are, as a general rule for the average overclocker.
There's also chips that have excellent core silicon but terrible IMC, fast cores that aren't fed with fast memory at low latency are bandwidth starved, and won't actually end up faster than a different chip with worse cores but a more normal IMC e.g.
The real question is "at what cost?"
6GHz at 250W simply isn't worth it when 5.5GHz is only 100W.
Had it on an Kraken X73 AIO direct die cooled with Conductonaut LM paste. At 1.3v the thing was an absolute fireball sucking down 384W TBP. Needed that AIO running max pump/fan speed to keep temps in check but it was game stable at 1035MHz and bench stable at 1067MHz. Sometimes the worse the silicon the harder you can push it.

Abandoning power efficiency and making the last juice of gigahertz is just far from smart. I'm saying this on both AMD and Intel.
What's the actual/realistic meaning of huge amount of power bringing that high clock speed? Who's gonna buy a CPU and see that number in monitoring software flying so high and making himself happy?
After all, if it's good, it's good; if it's rubbish, it's rubbish. Frequency game changes nothing.
Adjusting for more efficiency is a different ball park.
So I say the competition is going the wrong way. The major way I believe is still designing excellent microarchitecture and making it efficient. Otherwise, why not make a 10 nm version of Pentium 4 and make it 10 GHz, and say look we've got the first 10 GHz CPU in the world with small-sized footprint saying "oops if you ignore rubbish performance and astonishing power consumption". What about 7 nm version of 10 GHz Bulldozer? Does anybody like it or does it make any sense?
We all knew 13900KS would go for broke for bragging rights, power be damned. Brain dead and egregious waste of resources. Huang will do the same with Lovelace. Both will be under immense pressure going forward and Intel has to raise prices. 13900KS will be $850+ IMO. WIll be a perfect match for the ludicrous 4090Ti, better get that 1.5kW PSU order in quick.
