Alder Lake-S sample has 5.3GHz boost clock scores 11300 points in Cinebench R20
It's a rumor of the highest category this one, but a Chinese forum user claims to have a sample that reaches a boost clock speed of 5.3 GHz. At the end of this year, Intel will introduce the CPUs of Alder Lake; samples info will get leaked sometimes.
In any event, Core i9 12900K in question is an overclockable CPU with 8 Golden Cove cores and 8 Gracemont cores (BIG.little). In Cinebench R20's multi-threaded test he'd score about 11,300 points, which is 10% fasterer than a Ryzen 9 5950X.
The boost clock of 5.3 GHz is lower than expected, previously there were rumors of a boost clock of 5.5 GHz. The qualification sample designation means that it should perform more or less the same as the actual production model, while further improvements are possible for an engineering sample.
Twitter-based YuuKi AnS, says it does not yet have the full potential of Alder Lake, Windows 11 would be needed. This may have to do with the task scheduler since Windows 11 should better be able to handle CPU cores of various sizes. In addition, the frequency of the clock may still improve.
Corsair Talks DDR5-6400 And Faster Memory Incoming For Intel Alder Lake - 05/17/2021 09:37 AM
Corsair is thinking bigger and faster for Alder-Lake, in fact, if it's up to Corsair, 512GB or 1 TB systems of system memory are in the vicinity. The introduction of DDR5 is very close, and it should...

Cinebench and the like would probably be the best-case scenario for Alder Lake though, right?
Going to pull some numbers out of my backside just to illustrate my line of thinking here...
Let's say SMP adds ~30% to the performance of the big, conventional, cores under multi-core load. That would mean that in the top-end Alder Lake configuration (8+16) the little cores would need to achieve 65% (130/2) of the performance of the big cores to be competitive with a conventional, all-big, 16-core design with SMP.
That seems doable, or close to, and considering the die area used quite efficient.
Loads up to 8, or whatever number of large cores, should also be good.
Mixed loads between the end spectrums would probably be weaker but those workloads are likely rare in comparison, so Intel's design for Alder Lake makes a lot of sense.
All this assumes Windows can flawlessly manage hybrid processor designs and assign work appropriately. A big ask and I'd imagine the weakest point of this strategy.

I don't care about cinebench score, but care about gaming performance.
Intel better don't f..... up the latency like they did with Rocketlake.
Rocketlake has 20% higher cache latency than "Comedylake", so higher IPC goes down the drain with higher latency.
That's why tweaked cometlake with ~35ns memory is impossible to beat for tweaked Rocketlake in games.

11300 in Cinebench is only speculation by some random person on a Chinese forum. 9300 is the only actual (still only rumoured but at least not completely made up) CB R20 score so far.

I'd rather have lower clocks with more cores and threads.
Efficient, low power, highly optimized awesomeness - because clock speed is all intel can do, and that is not good enough.

not buying these scores.8 big + 8 little cores beating 5950x,by some margin.....
