Intel made an official announcement last year about the 14th generation Meteor Lake chip series. Since then, many high-end laptops featuring Core Ultra chips have been introduced. Alongside the high-performance Meteor Lake chips like the Intel Core Ultra 9 185H or Core Ultra 5 125H, Intel has quietly unveiled a new efficiency-focused chip, the Intel Core Ultra 5 115U, which interestingly was not initially included in the company's list of releases.
Key Details about Core Ultra 5 115U
This latest addition to the Meteor Lake lineup features a 2+4+2 configuration, comprising two performance cores, four efficient cores, and two low-power efficient cores, providing a total of 10 threads. The two performance cores deliver a maximum turbo frequency of 4.2 GHz, while their base frequency is set at 1.5GHz.
The four efficient cores have a maximum turbo frequency of 3.5GHz and a base frequency of 1GHz. As for the two low-power efficient cores, their maximum turbo and base frequencies are 2.1 GHz and 700MHz, respectively.
A Closer Look at Core Ultra 5 115U
Compared to the performance-oriented Core Ultra 5 125H (with a 4+8+2 configuration) found in recent laptop models like the ThinkBook 14 2024 Core Edition and ThinkBook 14+ 2024 SE, the Core Ultra 115U operates at lower peak frequencies across all cores. Notably, it boasts a 300MHz higher base frequency for the E and LPE cores in certain scenarios, likely to make up for the fewer number of cores.
This newly released chip comes equipped with a 10MB cache, whereas the Core Ultra 5 125H features an 18MB cache.
Graphics and Power Efficiency
The Core Ultra 115U supports rendering up to 7680 x 4320 at 60Hz through both HDMI 2.1 and DP interfaces, matching the resolution output capability of the Core Ultra 125H.
With a base power consumption of 15W, the Core Ultra 5 115U consumes nearly half the power of the 125H, which has a 28W base power consumption. Additionally, the maximum turbo power of the 115U is significantly lower at 57W compared to the 115W of the Core Ultra 125H.
