Intel Core i5-4430S

The Intel Core i5-4430S is a 2013-era quad-core desktop processor that, despite its age, lands in the 35th percentile of all CPUs tested, placing it squarely in the entry-level performance tier for modern workloads. Its average benchmark score of 1273 places it in a dead heat with a cluster of rivals, all within a single percentage point of each other, indicating that this is a processor whose performance ceiling has been firmly established and is now only suitable for basic computing, light productivity, and older games.

Benchmark Performance

The benchmark results for the Core i5-4430S tell a consistent story across all test suites: it is a functional, quad-core processor without hyper-threading, and its scores reflect that limitation. In Cinebench R23, the most demanding test in the data set, the processor achieves a multi-core score of 3709 and a single-core score of 523. The multi-core score is roughly seven times the single-core score, which is a typical ratio for a four-core, four-thread part, but the absolute values are low, indicating that heavily threaded modern applications will strain this CPU.

The Geekbench results reinforce this position. A multi-core score of 2773 and a single-core score of 980 show a processor that is nearly three times faster when all cores are engaged versus a single thread, but again, the raw numbers place it in the lower tier of the benchmark database. For context, the average benchmark score of 1273 is remarkably stable relative to its nearest rivals, with a deltaPct of only 0.1% against the Intel Core i5-6400 and -0.5% against the Intel Core i7-3610QE. This near-parity means that in synthetic aggregate scoring, the 4430S is indistinguishable from those parts, though real-world application behavior may vary slightly.

In Cinebench R20, the processor scores 1557 multi-core and 219 single-core. The ratio between these scores is approximately 7.1, which is nearly identical to the R23 ratio, confirming that the processor’s scaling efficiency is consistent regardless of the benchmark version. The Cinebench R15 scores of 373 multi-core and 52 single-core show a similar pattern, with the multi-core score being 7.17 times higher. This consistency across three generations of Cinebench indicates that the processor does not have any thermal or power throttling quirks that would alter its performance profile under sustained load; it simply delivers its expected level of performance relative to its architecture.

How It Compares

Intel Core i5-6400 (avgScore 1271, deltaPct 0.1%): The 4430S is statistically tied with the i5-6400, a newer Skylake part, in average benchmark score. This is a notable finding, as it suggests that the older Haswell architecture, when paired with a 65W TDP, can match the aggregate performance of a later-generation processor in these specific tests. However, the 6400 likely has better per-clock efficiency in single-threaded tasks, though the aggregate data shows no meaningful gap.

Intel Core i5-2550K (avgScore 1276, deltaPct -0.2%): The 4430S trails the older Sandy Bridge i5-2550K by just 0.2%, which is a negligible margin. This is an interesting comparison because the 2550K is a higher-clocked, unlocked part from a prior generation, yet the 4430S’s architectural improvements in Haswell effectively cancel out the clock speed disadvantage. For a user coming from a 2550K, the 4430S offers no performance upgrade.

Intel Core i7-3610QE (avgScore 1279, deltaPct -0.5%): The 4430S is 0.5% behind this quad-core, eight-thread mobile i7 processor. The 3610QE has hyper-threading, which should give it an advantage in multi-threaded workloads, but the 4430S’s higher clock speeds and desktop power envelope help it stay competitive. The aggregate score difference is trivial, meaning both processors perform at the same level in the overall benchmark suite.

Intel Core i3-10110U (avgScore 1279, deltaPct -0.5%): The 4430S matches a modern dual-core, four-thread mobile i3 from the 10th generation. This is a testament to the 4430S’s four physical cores, which allow it to keep pace with a much newer processor that relies on higher clocks and improved IPC. In single-threaded tests, the 10110U would likely win, but the aggregate score shows parity.

Who Should Consider It

The Core i5-4430S is not a processor for modern gaming or content creation, but its data supports specific use cases. For office productivity, the quad-core design with a 65W TDP is sufficient for spreadsheets, word processing, and web browsing with dozens of tabs. The Geekbench single-core score of 980 indicates that basic responsive tasks will feel acceptable, though not snappy by modern standards. For light, older games (pre-2015 titles), the processor’s multi-core score of 2773 in Geekbench is adequate, but it will bottleneck modern graphics cards.

For creation workloads, the Cinebench R23 multi-core score of 3709 is a clear warning: video editing, 3D rendering, or large batch photo processing will be slow. The processor lacks hyper-threading, so tasks that scale beyond four threads will see no benefit. Users who primarily run single-threaded legacy applications will find the R23 single-core score of 523 acceptable, but those who need to compress files or run virtual machines should look elsewhere. This processor is best suited for a secondary desktop, a home server, or a basic HTPC where the integrated Intel HD 4600 graphics can handle video playback without a discrete GPU.

Single-Thread vs Multi-Thread Behavior

The data reveals a processor that scales predictably but lacks headroom in both domains. In Cinebench R23, the multi-core score of 3709 is 7.09 times the single-core score of 523, a ratio that is typical for a four-core part without hyper-threading. This means that applications optimized for multi-threading will see a substantial speedup over single-threaded performance, but the absolute ceiling is low. The Geekbench results show a similar pattern, with a multi-core score of 2773 being 2.83 times the single-core score of 980, though this ratio is lower because Geekbench’s multi-core test does not scale as aggressively as Cinebench’s render workload.

For real-world use, this split means that a user will notice a significant difference between a single-threaded task, like opening a large PDF, and a multi-threaded task, like encoding a video. The single-core scores (52 in R15, 219 in R20, 523 in R23, 980 in Geekbench) are all low enough that any modern, well-optimized application will feel sluggish. Conversely, the multi-core scores, while still low, are at least competitive with the nearest rivals, all of which are within a 0.5% delta. The processor does not have a hidden advantage in one domain; it is uniformly modest.

Platform and Compatibility

The i5-4430S is built on the Haswell architecture and fits into the Intel Socket 1150 platform. It supports dual-channel DDR3 memory, which was standard for its era, but it lacks ECC memory support, meaning it is not suitable for error-correcting workloads like a home server with ZFS. The processor provides PCIe Gen 3 connectivity, which is sufficient for a single modern graphics card, though the CPU’s performance will likely bottleneck any high-end GPU. The integrated graphics are Intel HD 4600, which can drive multiple displays and handle hardware-accelerated video decode, but it is not suitable for gaming beyond very low settings.

The platform’s upgrade path is limited to other Socket 1150 processors, which are now obsolete. The processor is not overclockable, as the multiplier is locked, so users cannot extract additional performance beyond the boost clock of 3.20 GHz. The part number is SR14M, and it was released in June 2013. For a user building a new system today, this platform offers no modern advantages, but for someone with existing DDR3 memory and a compatible motherboard, it remains a functional, low-cost option.

Power and Thermals

The Core i5-4430S has a TDP of 65W, which is a modest figure for a quad-core desktop processor. This TDP class implies that a simple, low-profile air cooler is sufficient to keep the processor within its thermal limits. The low power draw also means that the processor will not generate excessive heat inside a small form factor case, making it a viable option for a compact HTPC or a basic office desktop. The 22 nm process node helps keep power consumption in check, and the 1,400 million transistor count on a 177 mm² die is efficient for its generation.

Because the processor is not overclockable, the 65W TDP represents a hard ceiling under sustained load. The benchmark scores show no evidence of throttling, as the multi-core to single-core ratios are consistent across all Cinebench versions. Users should pair this processor with a basic air cooler, not a large liquid cooler, as the latter would be unnecessary for the heat output. The lack of a launch MSRP in the data means no pricing information is available, but the power profile suggests that this is a processor designed for energy-conscious builds where quiet operation is prioritized over peak performance.
