Intel Core i5-4430

The Intel Core i5-4430 is a quad-core desktop processor from the Haswell generation, built on a 22 nm process with 1,400 million transistors and a 177 mm² die size. It operates with a base clock of 3.00 GHz and a boost clock of 3.20 GHz, drawing an 84 W TDP. Its benchmark profile places it at the 33rd percentile among all CPUs, with an average benchmark score of 1144, indicating a processor that sits firmly in the entry-level tier of modern performance expectations.

Benchmark Performance

The Core i5-4430’s raw performance is best understood through its Cinebench results, which show a clear separation between its multi-core and single-core capabilities. In Cinebench R23, the processor scores 3955 points in multi-core and 558 points in single-core. These figures translate to an average benchmark score of 1144, which places it in a tight cluster of rivals. The data shows the i5-4430 is essentially performance-identical to the AMD Opteron 4332 HE, with a deltaPct of 0, meaning both processors average exactly 1144 points. Against the AMD Opteron 4284, the i5-4430 trails by a negligible 0.2%, with the rival scoring 1146. The Intel Core i7-2600S also edges it out by 0.2%, posting an average score of 1147. Meanwhile, the AMD Athlon Silver PRO 3125GE sits 0.5% behind, scoring 1138. These deltas are remarkably small, suggesting that in aggregate throughput, the i5-4430 performs within a 1% band of all four nearest competitors.

Looking at the Cinebench R20 results, the multi-core score of 1661 and single-core score of 234 reveal a similar pattern. The multi-core score is roughly 7.1 times the single-core score, which is expected for a 4-core, 4-thread processor with no hyper-threading. In Cinebench R15, the multi-core score of 398 and single-core score of 56 show a ratio of approximately 7.1 as well, confirming consistent scaling across workload generations. The absolute scores are modest; for context, the R23 multi-core score of 3955 is the kind of result one would expect from a processor that is now several generations old. The 33rd percentile ranking underscores this — roughly two-thirds of all tested CPUs outperform it. The benchmark results indicate that the i5-4430 is not a performance leader, but its behavior is predictable and stable, with no anomalous spikes or drops across different Cinebench versions.

Who Should Consider It

The i5-4430 is a processor for users whose workloads are light on parallelism and heavy on simplicity. For office productivity — document editing, spreadsheet work, and web browsing — the quad-core design with 4 threads is sufficient, though the single-core score of 558 in Cinebench R23 suggests that even basic tasks will not feel snappy by modern standards. The 33rd percentile ranking means that a typical office user would notice slower response times compared to a contemporary mid-range CPU, but the system would remain usable for non-demanding applications.

Gaming is a mixed proposition. The i5-4430 has 4 cores and 4 threads, which matches the minimum requirements for many older titles, but the low single-thread performance — 234 in Cinebench R20 single-core — will bottleneck modern games that rely heavily on one or two threads. The integrated Intel HD 4600 graphics further limits gaming to older or less graphically intense titles, as there is no discrete GPU assumed in this analysis. For creation workloads like video editing or 3D rendering, the multi-core score of 3955 in Cinebench R23 is too low for anything beyond casual use. A single 4K video render or complex 3D scene would take considerably longer than on a processor with higher multi-core throughput. The i5-4430 is best suited for a secondary PC, a home server running lightweight tasks, or a basic desktop where the priority is low power consumption (84 W TDP) rather than high performance.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is a defining characteristic of the i5-4430. In Cinebench R23, the single-core score of 558 is only 14.1% of the multi-core score of 3955, which is the expected ratio for a 4-core processor with no SMT. This means that for every 1 unit of single-thread performance, the processor can deliver roughly 7.1 units of multi-thread performance when all cores are active. The same ratio holds in R20 (234 single vs 1661 multi) and R15 (56 single vs 398 multi), indicating that the core architecture scales linearly with thread count.

For real workloads, this behavior has clear implications. Applications that are single-threaded — such as older games, some spreadsheet calculations, or legacy software — will see performance close to the 558 score, which is low. The processor will feel sluggish in these scenarios, as it cannot leverage its other three cores. Conversely, multi-threaded workloads that scale well, such as batch photo processing or compiling code, will use all four cores and achieve the 3955 score. However, even this multi-core result is unimpressive; it is barely ahead of the AMD Opteron 4332 HE (1144 avg) and only 0.5% behind the AMD Athlon Silver PRO 3125GE. The data suggests that the i5-4430 was designed for a time when 4 cores were the standard, and its single-thread performance has aged poorly while its multi-thread performance has aged merely poorly.

Platform and Compatibility

The i5-4430 uses the Intel Socket 1150 platform, which was introduced with the Haswell architecture. It supports DDR3 memory in a dual-channel configuration, with no ECC support. The memory bus is dual-channel, but the FACT PACK does not specify a memory bandwidth figure, so no numerical comparison is possible. The processor includes an integrated GPU, the Intel HD 4600, which provides basic display output without a discrete graphics card. PCIe support is Gen 3, which is adequate for the era but limited by modern standards — a single modern GPU would still work, but the bandwidth is lower than what newer processors offer.

The upgrade path is constrained. Socket 1150 is a dead platform, meaning that users cannot install a newer-generation processor without changing the motherboard. Within the same platform, one could theoretically upgrade to a higher-tier Haswell CPU, but the FACT PACK does not list any such options. The processor is locked (multiplierUnlocked: false), so overclocking is not possible, which further limits any performance gains. The 84 W TDP is moderate, meaning that a standard air cooler is sufficient, but the lack of an unlocked multiplier means there is no headroom for tuning. For a user building a new system today, this platform offers no advantages in terms of memory speed (DDR3 only), storage interfaces, or modern connectivity. The processor’s release date of 2013-06-01 places it at over a decade old, and the 22 nm process node is several generations behind current manufacturing.

How It Compares

AMD Opteron 4332 HE: This is the closest rival, with both processors averaging exactly 1144 points. The deltaPct is 0, meaning they are perfectly matched in aggregate performance. However, the Opteron is a server-class chip, which suggests it may have different power characteristics or reliability features, but the benchmark data shows no performance difference. The i5-4430 matches it in every measured workload.

AMD Opteron 4284: The Opteron 4284 scores 1146, which is 0.2% higher than the i5-4430’s 1144. This is a statistical tie — a 2-point difference in average score is within normal run-to-run variance. The i5-4430 is effectively indistinguishable from this rival in performance, though the Opteron’s server heritage would typically imply higher core counts or different memory support, but those specs are not in the FACT PACK.

Intel Core i7-2600S: The i7-2600S averages 1147, also 0.2% ahead of the i5-4430. This is notable because the i7-2600S is an older Sandy Bridge processor, yet it still edges out the Haswell-based i5-4430. The 3-point score difference is negligible in practice, but it indicates that the i5-4430’s Haswell architecture did not deliver a generational leap over its predecessor in aggregate benchmarks. The i7-2600S also has hyper-threading (though not listed in the FACT PACK), which may explain its slight edge.

AMD Athlon Silver PRO 3125GE: The Athlon Silver PRO scores 1138, which is 0.5% lower than the i5-4430. This is the only rival that the i5-4430 clearly beats, though the margin is tiny. The Athlon Silver PRO is a much newer, lower-power chip, so its near-parity with the i5-4430 reflects how far entry-level performance has fallen relative to this old Intel chip. The i5-4430’s 6-point advantage is within the margin of error, but it does hold the top spot in this comparison group.
