Intel Core i5-4200U

The Intel Core i5-4200U is a dual-core, four-thread mobile processor from the Haswell generation, built on Intel's 22 nm process. With a modest average benchmark score of 762, it sits at the 20th percentile among all CPUs, indicating that it is positioned squarely in the entry-level performance tier for laptops. The data reveals a chip designed for basic productivity and light multitasking, where its low power envelope takes precedence over raw computational muscle. This analysis examines its benchmark scores, thermal characteristics, and platform fit to clarify where this processor stands in the modern landscape.

Who Should Consider It

The Core i5-4200U is best suited for users whose primary workloads involve web browsing, office document editing, email, and media consumption. Its Cinebench R23 multi-core score of 1857 points and Geekbench multi-core score of 1404 reflect a processor that handles everyday tasks without significant strain, provided the user does not push it with demanding parallel workloads. Single-threaded performance, measured at 262 points in Cinebench R23 and 733 in Geekbench, is adequate for responsive UI interaction and lightly-threaded applications, though it will show its age with more complex modern web pages.

For gaming, this processor is not a viable option beyond casual or legacy titles. The integrated Intel HD 4400 graphics lack the execution resources for contemporary 3D games, and the CPU's dual-core design with a 1.6 GHz base clock will bottleneck even modest graphics workloads. Users seeking any serious gaming performance should look at quad-core parts with higher clock speeds and discrete graphics support. Conversely, for office productivity and light spreadsheet work, the 4200U's four threads provide enough parallelism to keep such applications fluid, especially when paired with adequate memory.

Content creation is largely off the table. The Cinebench R15 multi-core score of 186 and R20 multi-core score of 779 show that video encoding, 3D rendering, and large batch photo editing would take excessively long. The processor is also not suitable for heavy multitasking scenarios, such as running multiple virtual machines or compiling software, where the lack of physical cores and low clock speed will cause significant slowdowns. In short, this is a chip for the secondary or tertiary laptop, not the primary workstation.

Power and Thermals

The 4200U carries a 15-watt TDP classification, which is the defining characteristic of the ultra-low-voltage mobile segment. This power envelope dictates the cooling solution: a slim, low-profile fan and heat pipe assembly typical of thin-and-light notebooks is sufficient. The data indicates that the thermal design is optimized for sustained operation in constrained chassis, where high sustained loads are not expected. Because of the 22 nm process node, the chip generates modest heat per unit area, allowing for passive cooling in short bursts, though active cooling will engage under sustained load.

The practical implication of the 15 W TDP is that the processor will maintain its base clock of 1.6 GHz indefinitely under a modest cooling solution, but boost clocks of 2.6 GHz are only sustainable for short periods before thermal or power limits pull them back. Laptop manufacturers using this chip typically implement conservative fan curves to keep noise low, trading performance for acoustics. Users should not expect to overclock or manually adjust power limits, as the multiplier is locked and the platform is not designed for enthusiast tuning. For battery life, the low TDP is a clear benefit, enabling long runtime on a single charge under light loads.

Benchmark Performance

The benchmark scores paint a consistent picture of a processor that performs just below average for its era. The average benchmark score of 762 places it in the 20th percentile of all CPUs, meaning roughly 80% of tested processors outperform it. In Cinebench R23 multi-core, the 1857 points reflect a dual-core part with hyper-threading that scales poorly beyond two threads; the single-core score of 262 points indicates a modest IPC improvement over older architectures but is far behind modern designs.

Geekbench results corroborate this: a single-core score of 733 and multi-core score of 1404 show a roughly 1.9x scaling from single to multi-core, which is expected for a 2-core/4-thread design. The Cinebench R20 scores of 779 multi-core and 110 single-core reveal a significant drop from R15 scores, which is typical since R20 is a more demanding workload. The multi-core to single-core ratio in R20 is 7.08x, which is anomalous for this class and suggests that the single-core score is disproportionately low relative to the multi-core score, likely due to thermal or power throttling during the shorter single-threaded test.

The data shows the 4200U trails the AMD A8-6600K by a negligible 0.2% in average score, effectively a statistical tie. Against the Intel Pentium Silver N5000, the 4200U is ahead by 0.2%, again within measurement noise. The closest rival, the Core i3-5020U, is beaten by 0.3%, and the Core i5-4250U by 0.4%. These deltas are all under one percentage point, indicating that within this performance class, the 4200U offers no meaningful advantage or disadvantage over its immediate peers.

How It Compares

vs. Intel Pentium Silver N5000: The 4200U holds a 0.2% average score advantage over the Pentium Silver N5000, which is statistically insignificant. The N5000 is a newer, quad-core design, but its lower clock speeds and architecture trade-off against the 4200U's higher boost clock and older IPC. In practice, the two chips will feel identical in everyday tasks, with the N5000 potentially edging ahead in heavily threaded workloads due to its extra physical cores, while the 4200U responds faster in single-threaded bursts.

vs. AMD A8-6600K: The A8-6600K is a desktop part with a much higher power envelope, yet it only manages to beat the 4200U by 0.2% in average score. This is a striking result, as the A8-6600K operates at significantly higher clock speeds and has a larger thermal budget. The benchmark data suggests that the 4200U's architecture is more efficient per clock, allowing the mobile chip to keep pace with a desktop processor that consumes several times more power.

vs. Intel Core i3-5020U: The 4200U outperforms the Core i3-5020U by 0.3%, a margin that is negligible in real-world use. Both are 15 W dual-core parts with hyper-threading, but the i3-5020U is from a newer generation (Broadwell) and has a slightly higher base clock. The benchmark parity indicates that Haswell's IPC advantage over its immediate successor is minimal, and users upgrading from a 4200U to an i3-5020U would see no measurable performance change.

vs. Intel Core i5-4250U: Against its direct sibling, the Core i5-4250U, the 4200U leads by 0.4% in average score. The 4250U has a marginally different clock configuration, but the benchmark results show the 4200U compensates with a slightly higher turbo frequency or better thermal behavior in the test suite. This is essentially a tie, confirming that the 4200U is not a differentiated part within its own family.

Platform and Compatibility

The 4200U is a mobile-only processor that uses the Intel BGA 1168 socket, meaning it is soldered directly to the motherboard and cannot be upgraded or replaced by the end user. It is based on the Haswell microarchitecture, which was released in 2013, and is manufactured on Intel's 22 nm process with 1,400 million transistors on a 118 mm² die. The processor supports DDR3 memory, though the fact pack does not specify the maximum capacity or speed, and it does not support ECC memory.

The integrated graphics are Intel HD 4400, which provides basic display output capabilities for office work and video playback but lacks the performance for gaming or GPU-accelerated compute. The fact pack does not list a PCIe specification, so the exact lane configuration is unknown, but as a mobile ultra-low-voltage part, it would typically offer limited PCIe lanes for connecting an SSD and wireless card. The platform's upgrade path is non-existent; because the CPU is soldered, the only path to improved performance is replacing the entire laptop. The processor has a locked multiplier, preventing any overclocking, and its part number is SR170. It was released on June 3, 2013, and is now considered a legacy product.
