Part of Intel's Meteor Lake generation and the first to carry the "Core Ultra" branding, the 125H combines fourteen cores and eighteen threads on a 4nm process with a dedicated NPU for on-device AI acceleration.
At 28W with a 4.5GHz boost clock, it represents a real platform shift for Intel — a tile-based chiplet design rather than a single monolithic die, aimed at laptops that want both strong everyday performance and AI-offload capability.
