The Alder Lake line is Intel's 12th generation series of chips based on a hybrid architecture that utilizes high-performance Golden Cove cores and energy-efficient Gracemont cores.  It is manufactured using Intel's Intel 7 process, formerly known as Intel 10 nm Enhanced SuperFin (10ESF).

And Intel's most advanced line of processors. Intel officially announced 12th Gen Intel Core CPUs on October 27, 2021. Without a full year, there has already been a leak with alleged engineering sample of a Core i9-13900 of last generation is online. The alleged CPU details were first published online via Twitter by Chinese website Expreview.

The only official information available is that the 13900 is clearly not a top-tier CPU, this has been confirmed directly by Intel.

However, based on the article written by Expreview and the CPU-Z screenshots they posted, this SKU apparently comes with 24 cores; eight of them are P-Cores, while the remaining 16 cores are E-Cores, bringing the total number of threads on the CPU to 32 threads.

On another note, the non-K nature of this 13900 also explains, to a measurable degree, the CPU's 65W TDP. That's low for a Core i9 processor, as the current top-tier Alder Lake generation SKU, the Core i9-12900KS, has a TDP requirement of 150W before you can even run it.

On the other hand, that reduced TDP could also explain why its boost clock is lower at 3,8 GHz and doesn't cross the 5 GHz domain like, again, current Core i9 series CPUs from 12th Gen Intel.

That said, Intel has recently confirmed that its 13th Gen Raptor Lake CPU series will support Efficient Thermal Velocity Boost and support TVB overclocking per core or package.

However, it was unclear whether Raptor Lake's non-K SKUs will support these features, which may be why the alleged 13900 is being limited to just 3,8GHz.

Additionally, we can also see that the 13900 will be based on the same Intel 7 process node, which is Intel's name for the 10nm array lithography it currently employs, having first introduced it with the release of Alder Lake. .
