VERDICT
Recommended Core™ Ultra 9 Processor 285H
Same tier, both fine; Core™ Ultra 9 Processor 285H just crosses the G-SCORE line first. Spec sheet: up to 5.4 GHz, 24 MB L3 cache, 16 / 16—Core™ Ultra 9 Processor 285H is built for sustained load, not just burst. Narrow the lens to AI Capability before you argue with G-SCORE alone. If Content Creation Index, Compute Index outranks everything, Core™ i9-12900 is the honest pick. Match your week against 35% higher on Efficiency Index, AI Capability (+11%)—that is the practical test. Happy building—may this save you one wrong click in the cart.
