Intel's 13th generation core for desktop PCs, Raptor Lake, is said to offer an additional performance mode on selected mainboards with the new 700 chipset, which allows the CPU up to 350 watts. In contrast to the 12th generation Core, Alder Lake, this should result in even more power.
Alder Lake already achieved up to 300 watts< /h2>
As a reminder: At the end of 2021, Intel declared the “turbo consumption level” PL2, which had only been officially available for a short time, as the new standard for the K-CPUs of the Alder Lake series, a fallback to a lower PL1 level (” the official TDP”) was no longer automatically provided after a certain time or when the weighted moving average of the fuel consumption reached PL1. Only excessively high temperatures should be able to cause K-CPUs to fall back from PL1 = PL2 to the Processor Base Power (PBP, the “old TDP”).
The Core i9-12900K thus continuously consumed up to 241 watts within the newly defined limits under full load. But on mainboards that ignored these limits, it went up to almost 300 watts in the editor's test.

At Alder Lake, the additional consumption was deflated
However, this brought virtually no performance advantage and Alder Lake was even more criticized for consumption at the start than the increase to a permanent 241 watts alone would have caused. Ultimately, this operating state was no longer covered by the official specifications.

Officially 350 watts at Raptor Lake should also bring something
As VideoCardz reports, citing ProHardver, Intel is said to be planning a new 350-watt mode for the 13th generation Core i9 based on Raptor Lake with the same number of P cores but more E cores, which is above the official one again slightly higher 253 watt PL1/PL2 limit.
In contrast to Alder Lake, the 100 watts should also provide more power in multi-core scenarios. This is probably due to the fact that the next Core i9 will offer e-cores instead of 16 instead of 8. The total power consumption is distributed over 24 instead of 16 cores. With the same TDP, the 13th gen of each core will therefore not work as close to the limit from which more power consumption is lost in virtually no clock gain as the predecessor. ProHardver speaks of up to 15 percent with 38 percent higher consumption.
CEO Gelsinger is presenting the 13th generation for the keynote speech at the Intel ON in-house exhibition on September 27th expected. According to the latest rumours, this is the same day AMD is releasing Ryzen 7000 – the final presentation will take place on August 30th. Raptor Lake is expected to launch in October.
