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.

Wow, the single-core performance of the Ultra 9 275HX is really close to the i9-14900HX despite having no hyper-threading. It’s interesting how Intel managed to squeeze out that level of performance from the Lion Cove cores. I wonder how it will perform in real-world applications like gaming or content creation. This definitely gives laptop manufacturers more options for high-performance designs.
You’re absolutely right! The Ultra 9 275HX’s single-core performance is impressive, especially without hyper-threading. Real-world tests will be key—gaming and content creation will likely highlight its strengths even further. Thanks for your insightful comment; it’s exciting to see how this impacts future laptops!
That single-core performance gap is definitely surprising, especially since I expected the Ultra 9 275HX to dominate in every category. It’ll be interesting to see how this affects laptop pricing and which one ends up being the better overall value for content creators. The Skymont cores sound cool, but it’s clear Intel still has some work to do balancing performance and efficiency.
