Intel's 13th Gen Core CPU Lineup Seemingly Leaks a Month Ahead of the Launch
Although this information hasn't been verified yet, it looks very plausible, but there are also some crucial bits missing. However, we now appear to have the full list of Intel Core 13000-series CPUs, that ranges from the Core i9-13900KF to the Core i3-13100. The information comes via Bilibili and should as such be taken with a grain of salt, but there are no big surprises here, except possibly the fairly low base clocks for some of the Core i9-13900K and KF SKUs, which sits at 3 GHz, compared to 3.2 GHz for the 12th gen equivalents.
What the leaker doesn't appear to have gotten hold of, is the boost frequency for the CPUs, possibly because Intel has kept it away from its partners so far. Earlier rumours have suggested boost speeds of 5.5 GHz or potentially even higher for a future KS SKU. Thanks to Intel adding additional E-cores into the mix, even the lower-end Core i5 CPUs will get four to eight E-cores this time around, whereas the 12th gen CPUs only offered E-cores on the Core i5-12600K and KF. Sadly the Core i3-13100 still gets to make do with only four P-cores. Intel is expected to reveal its 13th gen Core CPUs on the 27th or 28th of September.

It barely says anything really other than being a ballpark number for what is possible on that node.

Also, base clocks do not mean what a lot of people seem to think they mean. The base clock is the *highest* frequency that can be sustained by all cores indefinitely. At idle the cores run *below* the base clock. My Llano laptop idles at 800 MHz, while my Ryzen desktop has at least some cores running at 2.7 GHz or lower when idling despite having a 3.2 GHz base clock. "Turbo" clock is also a really misleading term. "Nitro" would be a much better analogy, actually.
HOWEVER a lower base clock in parallel and threaded loads is definitely harming your sustained perf in favor of higher peak clocks. Thats how it simply works. We used to have that in mobile CPUs, now its everywhere and its not desktop/workstation oriented even in 2022. Its just Intel marketing interfering with more efficient clocking. Thats their sell. Its not in our favor, its our energy bill that does suffer here.
For example, the 13600 is a 6+8 part and was leaked as a C0 stepping.
Which Alder Lake part is 6+8? None of the desktop parts are.
Or do we assume it is a cut down 8+8? Or perhaps a reworked Alder Lake mobile part (12700H was 6+8) to work in a different socket and chipset bus?
I find a lot of that to be highly unlikely.
They are assuming that if the Raptor Lake part stepping is at or above Alder Lake stepping it is Alder Lake, which may not be true at all.
The point I was highlighting in my 1st post of this thread is how they can stack more cache with 10nm in to raptor lake with the same die space as alder lake. But apparently according to thesmokingman, I'm a "fool" cause' I ain't no expert in node technology with cpu manufacturing. :rolleyes:
What TSMC Samsung and others did, was when they had 20nm and added FinFet they called it 16nm. There was no node shrink. Intel on the other hand, went from 22nm down an entire node and added FinFet. 14nm was accurate, but everyone else was on a 14/16nm node that was really 20nm + FinFet. They did not actually catch Intel's 14nm node until their 12/10nm nodes came out.
This is why Intel's 14nm node was about 30%-50% more dense than anyone elses 14/16nm node.
So using TSMC/Samsung standards, Intel 14nm = their 12/10nm. Imagine that.
That's when 'nanometers' became meaningless. It isn't something that Intel did, but all you have to do is look around and see how every analyst and 90% of 'enthusiasts' are completely taken in by the idea that N7 means 7nm. It doesn't, and it never has. TSMC N7 is about 10nm if you use the old logic gate + flip flop method of measurement.
Intel 4 is also more dense than TSMC N4 HP (high power, not for phones) node. It lands between TSMC N4 and N3.
- there are two base frequencies... one for the P-cores and another for the E-cores. The table doesn't specify. Unless the 2GHz is the E-core base frequency, it's a downgrade from AL (2.4GHz base). This could compromise OS responsiveness.
- it's missing the max boost clock. Why would you opt to leave out max boost? That will probably be the single most important spec for many users. I don't see a scenario where a leaker would only have access to base clocks, TDP, cache values but no max boost clocks?
- there is no total power rating for the CPUs, something Intel would've advised on, because early slideware targets system integrators...
That's why I think this is just a mix of speculation and facts taken from other posts, rather than an actual leak.It requires the motherboard to have been set with proper limits of course, which is almost never the case for "gaming" ones.
