Intel Core Ultra 9-285K 24-Core 24-Threads Desktop Processor

The Intel Core Ultra 9-285K Arrow Lake desktop processor forms an important link in the new generation.

The Core Ultra 9-285K retains the core configuration of its immediate predecessor—8P+16E, which means you get all eight Lion Cove performance cores present on the Arrow Lake-S silicon, and 12 out of 16 Skymont E-cores. A lot has been said about Skymont since its debut with the Lunar Lake mobile processor. Intel has given this E-core a 50% generational leap in IPC over Crestmont, and more than 30% compared to the Gracemont cores in Raptor Lake, considering the moderately high clock-speeds, they should contribute in a big way to multithreaded productivity workloads that scale across all cores. Unlike on Lunar Lake, the Arrow Lake E-cores and P-cores sit on a common CPU complex, sharing a ringbus and an L3 cache. The Core Ultra 9-285K is configured with 36 MB L3 cache. Each of the 8 P-cores comes with 3 MB of dedicated L2 cache, while the E-cores, organized in clusters of 4 cores each, has 4 MB of it per cluster.

Each of the eight Lion Cove P-cores on the Core Ultra 9-285K comes with a 3.70 GHz base frequency, while the maximum P-core boost is set to 5.70 GHz. From this, Turbo Boost 2.0 takes the P-cores to 5.40 GHz, while Turbo Boost Max 3.70 is used to push a couple of cores further up to 5.70 GHz. The twelve Skymont E-cores come with a 3.20 GHz base frequency, and boost up to 4.60 GHz. Intel 285K base power is rated at 125 W, and maximum turbo power at 250 W.
