Intel Core Ultra "Arrow Lake Refresh" Chips Focus on E-core Count and L3 Cache Uplifts
Intel's upcoming Core Ultra Series 2 "Arrow Lake Refresh" desktop processors are confirmed to bring CPU E-core count and L3 cache uplifts at their given price-points, recent benchmark leaks confirm. The series was originally rumored to consist of three SKUs, the Core Ultra 5 250K Plus, the Core Ultra 7 270K Plus, and the Core Ultra 9 290K Plus. The company was later reported to have cancelled the 290K Plus, and will proceed to launch the 250K Plus and 270K Plus very soon (details in our upcoming article).
The Core Ultra 5 250K Plus is significantly spruced up from the current Core Ultra 5 245K. The company has given this chip a 6P+12E core configuration, up from 6P+8E of the 245K. With three "Skymont" E-core clusters at its disposal, the chip also gets an increase in L3 cache, now increased to 30 MB, from the 24 MB of the 245K. There's also a nominal increase in frequency, with the P-cores boosting up to 5.30 GHz, a 100 MHz increase over the 245K. The Core Ultra 7 270K Plus is essentially a downclocked Core Ultra 9 285K. It maxes out the "Arrow Lake-S" silicon, enabling all 8 P-cores, all 16 E-cores, and the entire 36 MB L3 cache present, but has clock speeds resembling the Core Ultra 7 265K, with a maximum P-core boost frequency of 5.50 GHz, compared to 5.70 GHz of the 285K. The 270K Plus could also lack Thermal Velocity Boost available in the 285K. The 270K could come at an attractive price-point below that of the 285K.
