The 15th generation of Intel CPUs on the Arrow Lake architecture, represents a significant shift in Intel’s desktop and mobile CPUs strategy. The new naming scheme moves away from the traditional "Core i9" branding and introduces the "Intel Core Ultra" series. The flagship models in this generation are the Core Ultra 9 285K (desktop), the Core Ultra 9 285HX (high-performance laptop), and the Core Ultra 9 285H ( high-end laptop).
This guide combines all known market data, technical specifications, pricing, availability, and platform requirements as of 2026.
Processor Architecture & Manufacturing Process
The Core Ultra 9 series uses a multi-tile (chiplet) design, with each component built on the most suitable manufacturing node:
-
Compute tile (CPU cores): Intel 4 process (7nm-class)
-
Graphics tile (GPU): TSMC N3 (3nm)
-
NPU tile (AI accelerator): TSMC N3 (3nm)
-
I/O tile (interconnect and memory): TSMC N6 (6nm)
This hybrid approach allows Intel to combine its own process technology with TSMC’s advanced nodes to maximize performance, efficiency, and transistor density.
