Intel® Core™ Ultra 5 115U

The Intel Core Ultra 5 115U is a laptop processor with a hybrid 8-core layout (2 performance cores + 6 efficiency cores) and 10 threads, built on the Meteor Lake architecture (Intel 4 process). It launched in 2025. Clocks run from 1.5 GHz base to 4.2 GHz boost. A 10-MB L3 cache backs the cores (2.4 MB per core). The chip drops into the FCBGA2049 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 15 W.

The Intel Core Ultra 5 115U scores 3,126 in single-core performance and 11,532 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,004 for overall performance, 11,872 for productivity performance, 11,969 for creator performance, 11,820 for engineering performance and 12,261 for gaming performance. Its multi-core throughput works out to 1,442 per core, 1,153 per thread and 769 per watt. Its computed efficiency index is 1,550. Its performance index is 74, so its overall performance is 26% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Core Ultra 5 115U scores 38,545 in integer math, 28,296 in floating-point math, 126,933 in compression, 7,729 in cryptography, 840 in physics simulation, 7,511 in vector SIMD, 51 in the prime sieve and 13,844 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 35% below in integer math, 38% below in floating-point math, 44% below in compression, 33% below in cryptography, 23% below in physics simulation, 52% below in vector SIMD, 24% below in the prime sieve and 39% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Core Ultra 5 115U has 8 physical cores and runs 10 logical threads. It uses a hybrid layout of 2 performance cores and 6 efficiency cores. It runs at a base clock of 1.50 GHz and boosts up to 4.20 GHz.

The Intel Core Ultra 5 115U is a laptop processor, belongs to the Intel Core Ultra 5 family, uses the Meteor Lake architecture, carries the codename Meteor Lake and is manufactured on a Intel 4 process. It launched in 2025.

The Intel Core Ultra 5 115U has 800 KB of L1 cache, 8 MB of L2 cache and 10 MB of L3 cache. That adds up to about 18.8 MB of cache, or 2.35 MB per core.

The Intel Core Ultra 5 115U has a 3-level cache hierarchy: L1 at 800 KB, L2 at 8 MB and L3 at 10 MB. L3 is the largest level and makes up about 53% of the cache listed here.
