Intel's Core Ultra 5 245HX Laptop CPU Outruns Its Desktop Twin

[AleksandarK]

An early PassMark entry posted on X by the account "X86 is dead&back" offers a glimpse of Intel's Core Ultra 5 245HX notebook processor. The 14-core "Arrow Lake-H" mobile chip quietly outpaced its desktop counterpart, the Core Ultra 5 245, in both single-core and multi-core tests. The numbers themselves are straightforward. The 245HX recorded 4,706 points in single-core and 41,045 points in multi-core runs. By comparison, the desktop Core Ultra 5 245 logged 4,409 and 37,930, respectively, handing the notebook silicon a 7% lead in single-core results and an 8% advantage when all cores are engaged. Against the Core i5-14500, the 245HX is 19% faster in single-core work and 30% faster in heavily threaded tasks.

The gap widens further versus last year's mobile i5-14500HX, where the newcomer enjoys a 30% single-core margin and a 41% multi-core edge. The explanation is partly thermal. Intel grants the 245HX a maximum turbo power envelope of 160 W, well above the 121 W ceiling of the desktop 245. Clock speeds peak at 5.1 GHz, and the core configuration remains identical, pairing six performance cores with eight efficient cores. The higher TDP gives the HX version a chance to run at higher clocks for longer. Notebook manufacturers are expected to reveal Arrow Lake-HX systems later this quarter. Real-world gaming is a different arena, and PassMark is only one ruler. Yet the signs are hard to ignore: a mid-range laptop processor now outworks desktop counterparts.

Woops, thanks for pointing it out!

@AleksandarK would you know, for reference, what numbers the 245K achieves?

How do you mess up so badly.

 

[kondamin]

not the first time this happens, same happened back with the pentium m

I guess they're just binned chips hoping to optimize efficiency/battery life for laptops.

Battery life? With an HX-configured processor!? (I guess if you idle a lot! )

Yeah imagine how much worse they'd be if they just used the desktop dies or unbinned. I have a 13700H and the battery life sucks bad on it, IDK what Intel/Microsoft are doing but they're insanely power hungry compared to macs.
