Core Ultra 5 115U: a Meteor Lake with power far from being that “ultra”

Latest in the Meteor Lake range, the Core Ultra 5 115U is a processor equipped with only 2 efficient cores, but it consumes little.

Last December, Intel communicated on the revolution of its CPU offering for mobile computers, with the presentation and release of the Meteor Lake range through a large number of chips, including 6 for the U series.

These 6 chips have a clearly established hierarchy, but that was without counting on a latecomer. The Core Ultra 5 115 comes out of hiding, and we wonder if Intel’s new nomenclature is so relevant after all.

When presenting Meteor Lake, Intel logically insisted on the strongest processor in the range, the Core Ultra 9 185H and its 16 cores/22 threads, but the U series and its small TDP were not left out.

Indeed, to distinguish itself from the Meteor Lake H series, the U series has a TPD of 15 watts, with a maximum of 57 watts. It also counts on relatively high operating frequencies of 4.9 GHz on the efficient cores (P-cores) and another 3.8 GHz on the efficient cores (E-cores).

The objective of these frequencies is to compensate for the low number of cores, since on the entire U series, from the Core Ultra 5 125U to the Core Ultra 7 165U, you have to make do with 2 P-cores, 8 E-cores and 2 LP E-cores for up to 14 threads.

…well, not exactly, the 115U is in 2/4/2

Quite surprisingly, Intel had a seventh thief in its pocket. The latter is revealed today, while the American brand clearly indicates that its release dates back to December 2023. Like the others.

Why this secrecy? Perhaps because this newcomer does not quite fit the scenario written by Intel. Indeed, the Core Ultra 5 115U seems a step behind the Core Ultra 5 125U. So, instead of 8 E-cores and 14 threads, we have to make do with 4 E-cores and 10 threads.

The associated cache is logically limited to 10 MB (compared to 12 MB on all the others), and the frequencies drop a little further (100 MHz less than on the 125U). To make matters worse, the graphics part is cut by one Xe-core (3 against 4 on the other U), while the TDP is identical.

Already the name Core Ultra for the U series could seem excessive, especially compared to the H series, but here, we find ourselves with a 115U which seems very behind the scenes… at the risk of confusing or disappointing potential buyers.
