Intel’s upcoming Arrow Lake processors are set to be released in late October. This is in relation to the Arrow Lake-S desktop CPUs, but Intel has more coming up – HX processors for laptops. We don’t yet know whether these chips will be launched at the same time, but we can at least take a closer look at the specifications following a leak online.
While we have some performance leaks for the 15th-generation desktop CPUs, as well as the specifications and their box design, a recent leak has also showcased the specifications of their mobile counterparts, the HX variants for laptops.
Arrow Lake HX processor specifications
A post on X by Jaykihn (@jaykihn0) has showcased the specifications of six HX processors. There are two Core Ultra 9, 7, and 5 HX processors, each with varying clock speeds and cores, which isn’t unusual. We’ve put together a table highlighting the specifications.
| Name | Cores | Threads | Base clock speed (P/E) | Boost clock speed (P/E) | Single-core max clock speed (P/E) | iGPU EU/clock speed | TVB/TB3 |
| Core Ultra 9 285HX | 8+16 | 24 | 2.8 / 2.1 GHz | 5.5 / 4.6 GHz | 5.2 / 4.6 GHz | 64 / 2.0 GHz | Yes / Yes |
| Core Ultra 9 275HX | 8+16 | 24 | 2.7 / 2.1 GHz | 5.4 / 4.6 GHz | 5.2 / 4.6 GHz | 64 / 1.9 GHz | Yes / Yes |
| Core Ultra 7 265HX | 8+12 | 20 | 2.6 / 2.3 GHz | 5.3 / 4.6 GHz | 5.1 / 4.6 GHz | 64 / 1.9 GHz | Yes / Yes |
| Core Ultra 7 255HX | 8+12 | 20 | 2.4 / 1.8 GHz | 5.2 / 4.5 GHz | 5.0 / 4.5 GHz | 64 / 1.9 GHz | Yes / Yes |
| Core Ultra 5 245HX | 6+8 | 14 | 3.1 / 2.6 GHz | 5.1 / 4.5 GHz | 5.0 / 4.5 GHz | 48 / 1.9 GHz | Yes / No |
| Core Ultra 5 235HX | 6+8 | 14 | 2.9 / 2.6 GHz | 5.1 / 4.5 GHz | 5.0 / 4.5 GHz | 48 / 1.8 GHz | Yes / No |
So, as you can see, there isn’t much difference between the two Core Ultra 9 processors except that 275HX has a 0.1 GHz slower P-core base clock speed. As for the Core Ultra 7 CPUs, similar discrepancies can be seen, with the most noticeable difference being that the 255HX has 0.2 and 0.5 GHz slower P- and E-core base clock speeds.
This pattern is also noticeable in the Core Ultra 5 processors, but if the leaked benchmarks are correct, these chips should give the Ryzen 9000 series a run for their money. All in all, these specifications are leaked, and we recommend taking this information with a pinch of salt. This is the official word from Intel.
That said, we just have to wait a little longer before the 15th-generation desktop processors are unleashed, and their laptop HX variants should soon follow suit. In other Team Blue news, Intel is playing it safe to avoid more instability issues like with previous-generation processors.
