Intel Core i5-430UM Details

The Intel Core i5-430UM represents a significant step in mobile processor design, particularly for its era, offering a balance of performance and power efficiency that was well-suited for ultraportable systems. Released in the early 2010s, this processor is now considered a legacy device, with its technology now over a decade old. Despite its age, it was notable for integrating a dual-core architecture with hyper-threading, allowing it to handle multiple tasks efficiently within the constraints of a mobile platform. Built on Intel's Westmere microarchitecture and fabricated on a 32 nm process, the i5-430UM was a refinement of earlier designs, bringing improved power management and integrated graphics capabilities. Its relatively low TDP of 18 W made it ideal for thin and light laptops, emphasizing energy efficiency without sacrificing essential computing performance. The processor's integration of Intel's HD Graphics (Ironlake) with 12 execution units and a base frequency of 166 MHz, capable of boosting to 500 MHz, provided a level of graphical capability sufficient for everyday tasks and light multimedia consumption, though not suited for modern gaming or professional graphics workloads.

At the heart of the i5-430UM are two physical cores capable of four simultaneous threads, a configuration enabled by Intel's Hyper-Threading technology. This allows the processor to perform well in multithreaded applications, though its performance is constrained by a base clock of 1.2 GHz and a turbo frequency of 1.73 GHz, which activates under lighter workloads. The processor supports DDR3-800 memory and can address up to 8 GB of RAM, with a maximum memory bandwidth of 11.92 GB/s across two channels. It also features a robust cache hierarchy, including 0.125 MiB of L1 cache, 0.5 MiB of L2 cache, and a 3 MiB L3 cache, which helps reduce latency and improve data access speed. The chip is designed for the BGA-1288 package, indicating its integration into mobile motherboards where space and power constraints are critical.

In benchmark testing, the i5-430UM demonstrates its strengths and limitations. It achieves a single-core score of 3489, placing it near the bottom of the overall rankings, which reflects its outdated architecture and lower clock speeds compared to modern processors. The multicore score of 4229 is similarly modest, ranking it as a mid-tier performer in its class, with performance comparable to older dual-core processors from Intel and AMD. The overall score of 3785 confirms its position as a legacy mobile CPU, suitable for basic computing tasks but outpaced by nearly every modern processor. Its performance is comparable to contemporaries like the Core 2 Duo P9300 and Athlon II P340, but it trails behind newer designs such as the Intel Celeron N3060 and AMD A6-1450 in both single- and multicore performance.

The processor supports a range of modern features for its time, including Intel's Turbo Boost 1.0, Enhanced SpeedStep, and virtualization technology (VT-x). It also includes support for ECC memory, although this is not commonly implemented in consumer mobile systems. The integrated GPU supports up to two displays, a limitation by today's standards but adequate for basic multi-monitor setups. While the i5-430UM lacks the advanced features of current-generation processors—such as AVX-512 or AI acceleration—it was a reliable and efficient choice for mobile computing during its lifecycle. As of March 2026, the Core i5-430UM remains a relic of the past, useful only in legacy systems or for niche applications where low power consumption and basic performance are priorities.
