Intel Core Ultra 285K/265K and 245K get rumored boost clocks
Raichu reveals Intel next-gen desktop clocks.

The new leak featuring Core Ultra 7 265KF processor confirmed the configuration that was rumored for a few weeks before the new disclosure. This means that the leak from Raichu who was first to name the new lineup was indeed correct. New info on the boost clocks is helping to fill the specs gap in the Core Ultra 200K lineup.
According to Raichu, the Core Ultra series will feature the following boost clocks:
Core Ultra 9 285K vs. Raptor Lake-Refresh
- P-Core Boost : 5.7 GHz -300 MHz
- All-core Boost: 5.4 GHz
- E-Cores Boost: 4.6 GHz +200 MHz
Core Ultra 7 265K
- P-Core Boost : 5.5 GHz -100 MHz
- All-core Boost: 5.2 GHz
- E-Cores Boost: 4.6 GHz +300 MHz
Core Ultra 5 245K
- P-Core Boost : 5.2 GHz -100 MHz
- All-core Boost: 5.0 GHz
- E-Cores Boost: 4.6 GHz +600 MHz
It would appear that the E-Core (Skymont core) boost will be the same across all parts, which is 4.6 GHz. In terms of boost clocks for P-Cores (Lion Cove) this would be between 5.2 to 5.7 GHz and all-core boost would reach 5.0 to 5.4 GHz depending on the SKU. Overall, one is looking at 300 to 100 MHz lower P-Core speed and 200 to 600 MHz faster E-Core vs. 14th Gen Core “Raptor Lake Refresh”.
This isn’t the full spec disclosure yet. There are three non-K parts rumored to appear later, and their specs may need further confirmation. However, it is known that there will be K and KF variants, indicating that some SKUs will lack integrated graphics (Arc GPU).
Intel is expected to launch its Core Ultra 200K series, comprising six SKUs, in September, with availability anticipated a month later.
