More evidence is mounting about clock speeds for Intel Arrow Lake Us, and it looks as though the company is taking a much more conservative approach to megahertz with its forthcoming desktop processors. According to the latest leak, the new Intel Core Ultra 9 285K boost clock is significantly lower than that of its current two flagship 14th gen Us, which are currently struggling with stability problems in a number of games.
While the Intel is seemingly happy to run it at a lower clock speed, even when it's boosting.
This latest leak comes from regular Intel tech leaker OneRaichu, who has put up a cryptic Intel Arrow Lake range, which is widely rumored to be called the Core 9 Ultra 285K.
That "57" suggests that the maximum boost clock for the chip's P-Cores in lightly-threaded workloads will be 5.7GHz, dropping to 5.4GHz when all cores are engaged. We assume that the "47" refers to the boost clock of the power-efficient E-Cores in the chip being 4.7GHz, although, given that the E-Cores are only engaged in multi-threaded workloads, it's unclear what the "6" means here.
As a point of comparison, the Core i9 14900K has a top turbo boost clock of 6GHz, while the top-end Core i9 14900KS boosts to up to 6.2GHz, as long as you have a cooling system that can cope with it. Interestingly, though, both these Us have lower E-Core clock speeds than the 4.7GHz potentially mooted in OneRaichu's post. It may well be that Intel's new Us have more potent multi-threaded performance as a result.
Of course, none of this has been confirmed by Intel, and this is our reading of a cryptic post, so take this with a pinch of salt right now, but this isn't the first time Intel has been rumored to be winding down clock speeds on its new top-end chip. An earlier Intel clock speed rumor pointed to the Core Ultra 9 285K's clock speed being 12% lower than that of the Core i9 14900KS, putting it at around 5.53GHz.
