Core i3-4005U Details

The Intel Core i3-4005U, launched in September 2013, stands as a relic of the Haswell era, designed for mobile platforms with a focus on power efficiency and integrated graphics. As of March 2026, this processor is over a decade old, placing it firmly in the category of legacy hardware. Despite its age, the i3-4005U retains a niche role in low-power laptops and embedded systems where energy consumption and cost are more critical than raw performance. Its 22 nm manufacturing process and BGA1168 package reflect the technological constraints of its time, with a TDP of just 15 W enabling long battery life in thin-and-light devices.

The processor features a dual-core design with Hyper-Threading, effectively providing four threads, and operates at a base frequency of 1.7 GHz, boosting up to 2.3 GHz under load. It is built on Intel's Haswell architecture, which introduced significant improvements in power efficiency and integrated graphics performance compared to its predecessors. The chip includes 3 MB of L3 cache and supports DDR3L and LPDDR3 memory at speeds up to 1600 MHz, with a maximum memory bandwidth of 25.6 GB/s across two channels. This configuration allows it to handle basic productivity tasks and light multimedia use, though it falls short in modern, compute-intensive workloads.

One of the most notable aspects of the i3-4005U is its integrated Intel HD Graphics 4400 GPU. This graphics solution supports up to three displays and can operate at a burst frequency of 950 MHz, making it suitable for casual gaming and video playback. While it lacks the performance of contemporary discrete GPUs, it was a significant upgrade over previous generations and allowed for a completely integrated computing experience without the need for a dedicated graphics card.

In benchmark testing, the i3-4005U achieves an overall score of 4187, ranking #1698 out of 2060 processors, with a single-core score of 4159 (#1624) and a multicore score of 4229 (#1962). These results place it behind modern processors but show it is competitive with some older mobile chips like the Core 2 Duo P9300 and Athlon II P340. The multicore performance is slightly stronger than the single-core performance, indicating that it benefits from multithreaded optimizations to a modest extent. However, its performance lags significantly behind current high-end CPUs, as seen in the top 50 rankings where the highest-performing processors exceed 12,000 in multicore scores.

The processor supports a range of Intel technologies, including AES-NI for encryption, AVX for advanced vector operations, and Intel vPro for enhanced security and manageability. It also supports virtualization technologies such as VT-x and VT-d, enabling efficient virtual machine execution. However, its locked multiplier limits overclocking potential, a common trait in Intel's mainstream mobile lineup.

In conclusion, the Core i3-4005U is best suited for users requiring basic computing tasks—web browsing, document editing, and media consumption—without the need for high performance. While it is no longer competitive in the modern market, it remains a reliable option for budget laptops and older systems where energy efficiency and cost-effectiveness are paramount. For users seeking a capable machine today, even entry-level modern processors offer vastly superior performance and features.
