Intel officially announced its 14th generation Meteor Lake series chips towards the end of last year. We have seen plenty of high-end laptops with Core Ultra chips since then. Aside from the performance-focused Meteor Lake chips such as the Intel Core Ultra 9 185H or Core Ultra 5 125H, the company has silently released another efficiency-focused chip – the Intel Core Ultra 5 115U. Surprisingly, the company didn’t even include it in its SKU release list.

Key details about Core Ultra 5 115U

This new Meteor Lake offering comes with a 2+4+2 configuration, that is two performance-cores, four efficient-cores and two more low power efficient-cores, with a total of 10 threads. These two performance cores offer a max turbo frequency of 4.2 GHz where their base frequency is only 1.5GHz.

The max turbo and the base frequency of the four efficient cores are 3.5GHz and 1GHz respectively. Speaking of the two low-power efficient cores their max turbo and base frequencies are measured at 2.1 GHz and only 700MHz respectively.

In comparison to the performance focused Core Ultra 5 125H (4+8+2 configuration), which powers recently launched laptops like the ThinkBook 14 2024 Core Edition and the ThinkBook 14+ 2024 SE, the Core Ultra 115U runs on lower peak frequencies for all cores. Notably, it is rated for a 300MHz higher base frequency for the E and LPE cores as compared to the 125H, probably to compensate for the less number of cores in certain scenarios.

The newly released processor comes with a 10MB cache. For context, the Core Ultra 5 125H boasts 18MB cache.

Speaking of graphics, the Core Ultra 115U can render up to 7680 x 4320 at 60Hz both with HDMI 2.1 and DP. Notably, the resolution output of this chip is exactly the same as the Core Ultra 125H.

Core Ultra 5 115U offers a base power consumption of 15W, which is nearly half of the 125H’s 28W. The maximum turbo power is also a lot lower at just 57W as compared to the 115W of the other.
