Leaked Cinebench Run Shows Intel’s Core Ultra 7 251HX Crushing the Core i9 14900HX in Efficiency, Despite Trailing Its Own Sibling

A leaked Cinebench R23 run suggests Intel’s Core Ultra 7 251HX delivers strong multi-core performance at lower power than the Core i9-14900HX.

The chip appears especially efficient below 100W, highlighting better performance per watt than Intel’s previous flagship mobile CPU.

However, the Core Ultra 7 251HX still trails the higher-end Core Ultra 7 255HX, showing there’s still room in Intel’s Arrow Lake-HX lineup.
