The Intel Core-1800 chips is an engineering sample (ES), given its low base frequency of 1.8 GHz and early B0 stepping. The datasheet indicates the 16-core 24-thread processor to have eight Atom efficiency cores (which would be Gracemont cores without hyperthreading) and eight performance cores (Golden Cove with hyperthreading).

The leak shows that the Core-1800 ES has a PL1 (TDP) of 125 W that lasts for 56 seconds. The short-burst PL2 goes up to 228 W and lasts for just 2.44 ms. The PL2 value in this engineering sample is lower than the 251 W PL2 seen in Rocket Lake 8-core while being of extremely short duration. Rocket Lake 8-core and Comet Lake 10-core have a PL2 Tau that can last for up to 56 seconds. 

Apart from the power values, the datasheet also shows the turbo ratio limits for the Golden Coves and Gracemont cores at a 1.3147 V voltage. At this voltage, the big Golden Cove cores can attain:

• 4.6 GHz on 1-2 cores
• 4.4 GHz on 3-4 cores
• 4.2 GHz on 5-6 cores
• 4 GHz on all 8 cores

Alder Lake can support DDR5-4800 memory but only when paired with high-end Z690 chipset boards, which can also support DDR4-3200. Other 600-series chipset boards will offer only DDR4-3200 support. This makes sense considering that there's still some uncertainty regarding the mass production of DDR5 memory.

Alder Lake will also be the first mainstream desktop platform to support PCIe Gen5 with the CPU offering a total of 20 PCIe lanes (16 Gen5 + 4 Gen4). The PCH will offer another 28 PCIe lanes (16 Gen4 + 12 Gen3).

We are expecting the chip to be in the shops in September.
