Intel Core i5-2320 vs Intel Core i5-4440S Comparison

The Intel Core i5-2320 and the Intel Core i5-4440S are two quad-core desktop processors from different architectural generations, yet they occupy nearly the same performance tier in the aggregate benchmark data. The i5-2320, a Sandy Bridge part, posts an average benchmark score of 1083, while the i5-4440S, a Haswell part, scores 1078. This places both processors at the 30th percentile among all CPUs, indicating that despite the generational gap, their overall performance levels are remarkably close. However, the head-to-head benchmark results tell a more nuanced story, with the newer Haswell chip consistently pulling ahead in every single test recorded, while the older Sandy Bridge part maintains parity in average score through the specific mix of workloads in the database.

Where Each One Wins

The performance split between these two processors is decisively one-sided when examining the dedicated head-to-head benchmark suite. The Intel Core i5-4440S wins all five of the recorded comparisons, which include Cinebench R15, R20, and R23 in both single-core and multi-core variants. This gives the i5-4440S a clean 5-0 sweep in the direct competition, with no benchmark wins attributed to the i5-2320. The consistency of this result across different versions of the same rendering workload suggests that the Haswell architecture provides a fundamental efficiency advantage that scales across both lightly-threaded and fully-threaded tasks.

That said, the aggregate average benchmark scores introduce a subtlety: the i5-2320 actually edges out the i5-4440S by a margin of 1083 to 1078. This indicates that in the broader database of benchmark results, the older Sandy Bridge chip performs slightly better on some unspecified workloads not included in the head-to-head suite. For users whose applications align with those untracked tests, the i5-2320 may hold a small advantage. However, for the specific Cinebench rendering tests that are directly compared, the i5-4440S is the clear winner. The i5-2320’s wins, if any, lie outside the documented head-to-head set; within the measured data, the i5-4440S dominates.

Architecture Differences

The two processors come from different architectural eras, which explains their divergent performance characteristics despite identical core and thread counts. The i5-2320 is built on the Sandy Bridge architecture using a 32 nm process node, manufactured by Intel with 1,160 million transistors on a 216 mm² die. The i5-4440S, in contrast, uses the Haswell architecture on a more advanced 22 nm process, packing 1,400 million transistors into a smaller 177 mm² die. This transistor density improvement is a key differentiator, allowing Haswell to deliver higher performance per clock and better power efficiency.

Both processors feature four physical cores and four threads, with no hyper-threading support, which keeps them on equal footing in terms of parallel thread capacity. The base clock speeds differ slightly, with the i5-2320 running at 3.00 GHz compared to the i5-4440S’s 2.80 GHz, but both boost to the same 3.30 GHz maximum. The cache hierarchy is identical: 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. Memory support is also matched at dual-channel DDR3, with no ECC support on either part. The i5-2320 uses the Intel Socket 1155, while the i5-4440S uses the newer Intel Socket 1150, meaning they are not platform-compatible.

The integrated graphics differ significantly, with the i5-2320 featuring Intel HD 2000 and the i5-4440S featuring the more capable Intel HD 4600. The i5-2320 lists PCIe Gen 3 with 16 lanes from the CPU, while the i5-4440S lists PCIe Gen 3 without a lane count specified. Power consumption is a major architectural differentiator: the i5-2320 carries a 95 W TDP, while the i5-4440S is a low-power "S" variant at 65 W TDP. This 30 W reduction in thermal design power, combined with the smaller die and newer process, makes the i5-4440S a more attractive option for power-constrained builds, though the benchmark data shows this efficiency does not come at the cost of performance.

Head-to-Head Benchmarks

The head-to-head results reveal a consistent pattern of the i5-4440S outperforming the i5-2320 by roughly 15.5 to 15.6 percent across all tested workloads. In Cinebench R15 multi-core, the i5-2320 scores 317 while the i5-4440S reaches 375, a difference of -15.5 percent from the perspective of the older chip. The R20 multi-core test shows a similar gap: 1321 versus 1566, a -15.6 percent delta. This trend continues in R23 multi-core, where the scores are 3146 for the i5-2320 and 3729 for the i5-4440S, again a -15.6 percent difference.

Single-core performance tells the same story. In Cinebench R20 single-core, the i5-2320 scores 186, while the i5-4440S scores 220, a -15.5 percent gap. The R23 single-core test shows 444 versus 526, a -15.6 percent difference. The i5-4440S also has a Cinebench R15 single-core score of 52, though the i5-2320 does not have a corresponding entry in the head-to-head data. The consistency of these deltas — all hovering within a narrow 15.5 to 15.6 percent band — suggests that the performance advantage of the i5-4440S is architectural rather than workload-specific. It is not that the Haswell chip excels at a particular type of computation; rather, it delivers a uniform IPC uplift across the board.

This uniformity is notable given that the i5-2320 has a higher base clock (3.00 GHz versus 2.80 GHz). Despite starting at a lower clock speed, the i5-4440S still manages to outperform the i5-2320 by the same margin in both single-threaded and multi-threaded tests. This indicates that the Haswell architecture’s instructions-per-clock advantage more than compensates for the 200 MHz base clock deficit. The fact that both chips boost to the same 3.30 GHz maximum makes the comparison even more telling, as the i5-4440S achieves its superior scores while operating at the same peak frequency.

The Verdict

The data points to a straightforward conclusion: the Intel Core i5-4440S is the superior processor in every directly measured benchmark. With a 5-0 win record and consistent 15.5 to 15.6 percent leads across Cinebench R15, R20, and R23 in both single-core and multi-core workloads, the Haswell part demonstrates a clear generational advantage. The i5-4440S achieves these results while drawing significantly less power, with a 65 W TDP versus the i5-2320’s 95 W TDP. For any user prioritizing rendering performance, multi-threaded workloads, or energy efficiency, the i5-4440S is the better choice.

The i5-2320 does hold a marginal edge in aggregate average benchmark score (1083 versus 1078) and matches its rival in the 30th percentile ranking among all CPUs. This suggests that in certain unlisted workloads, the Sandy Bridge chip performs slightly better, potentially due to its higher base clock of 3.00 GHz. However, the absence of any head-to-head win for the i5-2320 means that its advantages are not captured in the documented comparison suite. For users with specific applications that favor the older architecture, the i5-2320 might be sufficient, but the measured data across all common Cinebench versions favors the i5-4440S. The choice is clear for most users: the i5-4440S offers better performance, better efficiency, and a more modern feature set.
