Intel Ultra 9 275HX vs i9-14900HX: Surprising Single-Core Performance Comparison & Benchmarks
At CES 2025, Intel made waves by unveiling its cutting-edge Arrow Lake HX series notebook processors, headlined by the powerhouse Core Ultra 9 275HX.
This revolutionary chip packs a serious punch with 8 blazing-fast Lion Cove performance cores and 16 ultra-efficient Skymont cores, ditching hyper-threading to deliver a formidable 24-core/24-thread configuration.
Surprisingly, early Cinebench R23 benchmarks reveal the Core Ultra 9 275HX narrowly trails last year’s Core i9-14900HX in single-core performance—a result that’s raising eyebrows across the tech community.
The numbers don’t lie: Intel’s newest flagship managed 2,161 points in single-core testing, falling just short of its predecessor’s typical 2,200-point performance.
But here’s where it gets interesting—despite the absence of hyper-threading, the Core Ultra 9 275HX flexes its muscles in multi-core performance, racking up an impressive 35,481 points. That’s a whopping 18% leap over Raptor Lake’s best efforts.
While single-core gains may seem modest now, industry experts anticipate significant performance boosts as BIOS updates and software optimizations roll out in coming months—making this just the beginning of Arrow Lake’s potential.
