Intel Core Ultra 275HX Outshines Core i9-14900HX by 33% in Early Passmark Appearance
A recent Cinebench R23 result portrayed the upcoming Intel Core Ultra 9 275HX lagging behind its predecessor by a few points in single-core performance, despite pulling well ahead in multicore performance. Now, the high-end Arrow Lake-HX chip has made its debut on Passmark, and the result appears quite enticing, to say the least. In single-core, the Core Ultra 9 275HX leads the i9 14900HX by around 10% - a fair generational uplift. In overall performance, however, the Core Ultra 9 275HX shines bright, pulling off a 33% lead over its predecessor. Of course, the actual improvements are likely to be lower, considering that the Passmark database contains over 1800 entries for Core i9 14900HX-powered systems with varying thermal capabilities, while only a single one so far for the 275HX.
For a refresher, the Core Ultra 9 275HX debuted at CES 2025, and packs 8 Lion Cove P-cores along with 16 Skymont E-cores. Intel has left Hyper-Threading in the rearview mirror with its Arrow Lake lineup, although the Passmark entry seems to suggest Arrow Lake-HX will do just fine without it. Unsurprisingly, for laptops, the performance of the system will boil down to its thermal capabilities, which basically means that there will be a plethora of systems where the 275HX will be unable to fully spread its wings. Besides that, as with all pre-release performance benchmark leaks, be sure to accept this information with a grain of salt. The Ryzen 7945HX3D is also left behind, albeit by a far smaller margin of just around 7% in overall performance. With the Ryzen 9 9955HX3D just around the corner, however, Intel's high-end laptop reign might be short-lived after all.

Also, it is Not clear where the 33% came from?
To add, when you look at turbo speeds, the exact opposite of what you assume is happening here.
The reason it doesn't do better vs the 14900HX in single thread is likely due to having ~7% slower max turbo speed. That affects single thread, where the CPUs can maintain that turbo on one core.
So if you normalized in the correct direction, if both were running at the same clock, the 275HX would be ~17% faster in single thread. That is just mental masturbation though, the chips run at the frequencies they run at.
In multi-thread, they can't maintain max turbo and it's anyone's guess where they land without a benchmark. However, based on this benchmark, the 275HX is able to maintain its turbo much better than the older 14900HX. Plus it has an IPC advantage.
This shouldn't be very surprising though. 14900HX is an Intel 7 part and derivative of a design launched 4 years ago. 275HX is TSMC N3B and a new design.
Me: so wtf have you been doing previously?
This feels like progress Intel already had and then threw in the shitter
Both results are Valid and final calculated result depends on what number is selected as a base for 100%, that is 45615 or 61010.
Not a big deal to continue talks... :)
