Intel Core Ultra “Arrow Lake-S” desktop processors are expected to debut later this year, and introduce the new Lion Cove P-cores, along with Skymont E-cores to the desktop platform. Engineering samples and qualification samples with specs close to retail chips seem to already be in the hands of PC OEMs and motherboard vendors, given the volume of leaks over the past few days. Jaykihn0, one of the more influential sources of these leaks, revealed a few interesting details of the maximum boost frequencies of these chips.
The QS of a top Core Ultra 9 “Arrow Lake-S” SKU, probably the flagship model that succeeds the current Core i9-14900K, is described as having a maximum P-core boost frequency of 5.70 GHz, and an all-P-core boost frequency of 5.40 GHz. The maximum E-core boost frequency, which is also the all-E-core boost frequency, is said to be 4.60 GHz. Let’s unpack this. “Arrow Lake” uses the same mix of “Lion Cove” P-cores and “Skymont” E-cores as “Lunar Lake,” albeit arranged along a ringbus, and sharing an L3 cache, unlike on “Lunar Lake,” where the P-cores have their own exclusive L3 cache, and the E-cores are arranged in a low-power island, with the fabric of the SoC tile connecting the two.
