Embedded Processor Features & Applications
- 255H is the Core Ultra 7 Arrow Lake H-series: 16 cores (6 P-cores) but only 16 threads because Hyper-Threading is removed in Arrow Lake H-series.
- Intel Arc 140T GPU has 8 Xe-vectors (vs 7 in 225H Arc 130T) and higher GPU compute for content creation and gaming.
- P-cores reach 5.1 GHz max turbo (vs 4.9 GHz in 225H); 200 MHz advantage in single-thread performance for premium notebooks.
- 24 MB Intel Smart Cache (vs 18 MB in 225H) and support for LPDDR5 × 8400 MT/s with 128 GB max target high-end notebook platforms.
- Same FCBGA2049 footprint as Meteor Lake and Arrow Lake H-series; board can be reused with BIOS update for different Core Ultra tiers.
- NPU 13 TOPS with WebNN support; TSMC N3B process brings efficiency improvements vs Intel 4 in Meteor Lake.
