Intel Core i5-1230U: A Power-Efficient Processor for Thin and Light Laptops

Intel Core i5-1230U

In the ever-evolving world of technology, Intel has consistently been at the forefront of processor innovation. One of their notable offerings is the Intel Core i5-1230U, a mobile CPU specifically designed for thin and light laptops. Launched in early 2022 as part of the Alder Lake architecture, this processor brings a range of performance enhancements and energy efficiency features to meet the demands of modern computing.

Performance Capabilities

The Intel Core i5-1230U incorporates a combination of 2 performance cores (P-cores) and 8 efficient cores (E-cores), based on the Golden Cove and Gracemont architectures, respectively. The P-cores support Hyper-Threading, enabling a total of 12 supported threads when combined with the E-cores. This multi-threading capability allows for improved multitasking and overall responsiveness.

The processor operates at a clock rate ranging from 1 to 4.4 GHz on the performance cluster and 0.7 to 3.3 GHz on the efficient cluster. While the P-cores provide superior performance, the E-cores offer efficiency similar to the older Skylake cores, comparable to the Core i7-6700HQ. All cores can utilize up to 12 MB of L3 cache, which enhances data access speeds and overall system performance.

Compared to its counterpart, the Core i5-1240U, the Core i5-1230U features a lower base CPU clock speed and only includes "Essentials" vPro management features. This makes the Core i5-1230U an excellent choice for users who prioritize power efficiency over higher clock speeds and advanced management capabilities.
