Intel Core Ultra 9 285K "Arrow Lake" CPU surfaces with 5.7GHz clock speed

What just happened? Intel is expected to officially announce its Arrow Lake-S desktop CPU lineup later this year. A steady stream of leaks has already provided some insight into what to expect from the new processors, and a recent Geekbench listing appears to have revealed the clock speed of the flagship Arrow Lake chip.

According to the listing, the Intel Core Ultra 9 285K CPU will offer a boost speed of up to 5.7GHz, which is about 500MHz lower than the 6.2GHz Max Turbo Frequency of the Raptor Lake flagship, the Core i9-14900KS. The 285K is also expected to have a 3.7GHz base clock, slightly higher than the 3.2GHz P-core base clock of the Raptor Lake flagship.

In the Geekbench 6.3 runs, the Core Ultra 9 285K scored 3,449 points in the single-core test and 23,024 points in the multi-core test. These scores are notably higher than those of the Core i9-14900K, suggesting that Arrow Lake could indeed be a worthy upgrade over Raptor Lake, as leaks have indicated. For comparison, the i9-14900KS achieved 3,189 points in the single-core test and 21,890 points in the multi-core benchmark on the same platform.

The Core Ultra 285K was tested on an Asus ROG STRIX Z890-A Gaming WIFI motherboard with 64 GB of DDR5-6400 memory. The listing also confirms earlier leaks that the new chip has 24 cores in total, including eight performance cores and 16 efficiency cores. The chip is also rumored to include 36 MB of L3 cache and feature a 125W PL1 TDP.

While Intel has yet to announce a definite launch date for the Arrow Lake lineup, a recent leak suggested it could arrive on October 10. Alongside the flagship Core Ultra 9 285K, Intel will likely also unveil the more mainstream Core Ultra 7 265K and Core Ultra 5 245K, all of which are expected to feature unlocked multipliers for overclocking. Intel's motherboard partners are also anticipated to announce their flagship LGA 1851 boards on the same day.

The new processors are rumored not only to offer significant performance gains over Raptor Lake but also to be more power efficient and stable than their predecessors. At a recent event in China, the company claimed that Arrow Lake will consume "at least" 100 watts less power than its current lineup. Intel is also hoping that the new lineup will avoid the stability issues that have affected many of its 13th- and 14th-gen Core CPUs.
