Alder Lake-S will require a new motherboard as the chips will adopt the new LGA1700 socket. There will be a number of new features too, including DDR5 and PCI Express 5.0 support. Intel was really late with PCI Express 4.0, but they're following up with PCI Express 5.0 very rapidly.
Intel Core-1800 ES2 spotted with up to 4.6GHz Boost
German tech site Igor's Lab spotted a datasheet that details the specifications of the Intel "Core-1800" processor. This seems like a temporary name, based on the base clockspeed of this engineering sample. The specifications list reveals it's an Alder Lake-S processor with B0 stepping, it's a second revision engineering sample (ES2).The part has a total of 16 cores, which includes 8 high-performance cores and 8 energy-efficient cores. Only the high-performance cores support hyper-threading so you get a total of 24 threads on this chip.
As this is not a qualification sample (QS) yet, we can expect the final retail parts to have higher clockspeeds. The values listed for this ES2 part are all a lot lower than what we see with Rocket Lake-S. This sample has a relatively low base frequency of 1.8GHz. The datasheet reveals there is a 4.6GHz Boost with two cores, a 4.4GHz Boost with four cores, and a 4.2GHz Boost with six cores. The all-core Boost is listed as 4.0GHz.
The hybrid architecture makes talking about frequencies a bit more complex. The above-listed values are for the high-performance cores. The datasheet does not reveal the frequency of the Atom cores, but notes a 3.4GHz Boost will be possible with up to half of the Atom cores. The all-core Boost for the Atom cores is 3.0GHz.
This sample has a Power Limit 1 TDP of 125W but the PL2 value is increased to 228W.
