One of Intel’s Alder Lake processors has seemingly been spotted again, and this model is apparently the Core i7-12700K, going by the specs listed.
As highlighted by hardware leaker @harukaze5719 on Twitter, the processor was discovered lurking in the SiSoftware Sandra database.
Probably i7 12700K- 12C 20T (misreported as 24T)- 8*1.25MB + 4*384KB = 11.5MB L2> L2 cache is reported as 9 core, I think that is right due to 4 small core = 1 cluster. Benchmark could recognize cluster unit. - 8*2.75MB(cut from full of 3MB) + 4*768KB = 25MB L3 https://t.co/fO84Bz2qM3August 9, 2021
While this sample chip isn’t identified in the database entry, based on previous leakage around Alder Lake, assuming this is a genuine CPU and not some kind of fabrication, it’s likely to be the Core i7-12700K – as that’s the processor which is rumored to run with 8 high-power cores and 4 power-efficient ones.

As @harukaze5719 observes, there appears to be an error in reporting the threads, which are listed as 24 – when this should be 20-threads (the 8 performance cores offer multi-threading, for 16-threads, but the low-power cores don’t, so that adds just another 4-threads to make 20 in total).
Another oddity is that the L2 cache is reported for 9-cores, but what seems to be happening here is the 4 low-power cores being recognized as a single cluster – one core – added to the 8 performance cores, as @harukaze5719 clarifies.
Sadly, the clock speeds detailed here – a base clock of 1.2GHz and Turbo to 3.4GHz – are obviously way too low, which is due to this being an early sample chip, with the finished CPU going to run much faster than that, of course.
Remember that the top-tier Core i9-12900K is expected to boost to 5.3GHz according to the word from the CPU grapevine, and the Core i7 shouldn’t be too far off that mark – but take plenty of condiments with all this speculation, naturally.
Analysis: Alder Lake is on track for end of October?
The Alder Lake rumors are starting to flow more regularly now, and the sighting of another sample chip – among a number of other leaks in the past month or so – is yet another morsel of evidence pointing towards Intel staying on track with its launch timeframe for the 12th-generation desktop silicon. (Don't forget that we've also seen reports of pre-release samples already being sold over in China on the black market).
That launch could come as early as October 27, with Intel itself having dropped hints that the Intel ON event, which kicks off on that date in San Francisco, could be the platform for the revelation of Alder Lake. The rumor mill has already put forward this timeframe, and that Alder Lake chips could launch alongside Window 11, with Microsoft making under the hood tweaks to allow Intel’s processors to run better with its revamped operating system.
If this speculated launch timeframe is in the right ballpark, we can expect further sightings of the 12700K – and other Alder Lake products – to pitch up soon enough, with hopefully further insight into the kind of performance we might be looking at when, as will inevitably happen, more leaked benchmarks emerge.
