Intel Core i9-13900KS Could be World's First 6 GHz Processor

[btarunr]

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.

6GHz base clock would be impressive. Oh wait, boost clocks? Those don't count. That's like going to a race as a spectator, seeing the finish line before the race has even started and saying, "I finished!".

 

[Crackong]

8GHz OC WR?

Did they actually looked up the OC WR ?

Btw, That 'Ghz' is a terrible mistake if it is an official Intel PPT

LOL. AMD's 5.7GHz spoiled Intel's marketing?

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.

Or maybe boosted Intels frequency and doubled the power consumed? Since Intel is advertising the 6ghz, the idea of an Intel top chip sucking 400watts seems plausible now.

Worlds first CPU to combust at 6GHz......

 

[fevgatos]

Ipc increase over alderlake? Doubt

 

[Deleted member 185088]

Given that high end AIOs struggle with 12900KS what kind of cooling solution you'd need to cool this alleged CPU?

 

[Fasola]

Time to bring that old chiller out.

[Outback Bronze]

Looking forward to reviews to see how much higher these can be clocked.

 

[ratirt]

I see that the advertisement and bragging is about the OC. Like it matters much though. It would seem this has nothing to cover except an OC numbers.
To be fair this does not look promising.

 

[Solid State Brain]

Lower-than-average silicon quality 12900KS had an internally programmed voltage target above 1.5V for the highest frequency point of 5500 MHz, I wonder if the 13900KS will go beyond that.

 

[Dirt Chip]

Well, thay need something to counter the 3D AMD magic chips.

A '6GHz first' can definitely do PR work very well.

What is "base clock"?

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.

So the CPU can draw up to 400 w if pushed to 6 Ghz? Ok? The people who want that can cool it, it's a similar load to GPUs, which have been successfully watercooled with ambient hardware for years.

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.

Be nice for them to manage a first, it's been a while.

Intel 10nm is superior to tsmc's 5nm.. intel 4 will break the 10ghz

400w, but on ~240-250mm^2 at most.
The most power hungry GPUs were 350-400w with >600mm^2 die

Fixed with good IHS substrate and solder, further fixed if you delid and apply liquid metal. For the people who care about 200Mhz 6Ghz numbers, this isn't a significant obstacle.

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.

Funny and wrong.
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

Tec coolers are useless for all core workloads

Good thing 6 Ghz won't be an all core workload then.
