Its table lists the 275HX with 24 cores (8+16), 5.4 GHz P-core turbo and 55 W base and 160 W turbo power. The table's E-core base clock of 1.9 GHz differs from ARK's 2.1 GHz, so ARK is used.

ARK states no module type, rank or LPDDR option for this chip. The SODIMM module type comes from Intel's CES 2025 release and Wccftech. No module configuration is stated, so config is left out.5Press articlewccftech.com/intel-core-ultra-200hx-core-ultra-200h-arrow-lake-cpus-debut-high-end-gaming-premium-laptops/ampRead 14 October 2026Wccftech, January 2025, from Intel's briefing: the 200HX CPUs support standard DDR5-6400 SO-DIMMs, or OEMs can use LPDDR5X or LP5/5x CAMM2. ARK lists only DDR5 for this chip, so only the DDR5 SODIMM row is stored.
