Intel Core Ultra 5 125H

The Intel Core Ultra 5 125H is a 14-core (18-thread) processor built for the mobile CPU market. It launched in Q4 2023. It is part of Intel's Ultra 5 lineup, which is based on the Meteor Lake microarchitecture. The Ultra 5 125H is compatible with Intel BGA 2049 motherboards and is fabricated on Intel's 7 nm manufacturing process. It features the Arc Xe-LPG 96EU integrated graphics solution.

Memory and Cache

The Core Ultra 5 125H supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core Ultra 5 125H has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 112 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 18 MB.

Cores and Clock Speeds

The Core Ultra 5 125H features 14 total cores which can process 18 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 14 cores consist of 4 P-Cores and 10 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 3.6 GHz, and it can boost up to 4.5 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core Ultra 5 125H includes an integrated graphics solution called Arc Xe-LPG 96EU. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.
