Intel Core i3-4160 vs Intel Core i5-2500S Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core i3-4160 wins every recorded test against the Intel Core i5-2500S. Across five Cinebench workloads, the i3-4160 maintains a consistent lead of roughly 3.1% to 3.6%, making it the faster processor in both single-threaded and multi-threaded scenarios.

In Cinebench R15 multi-core, the i3-4160 scores 297 against the i5-2500S's 288, a 3.1% advantage. The same pattern holds in Cinebench R20 multi-core, where the i3-4160 posts 1241 versus 1204, again a 3.1% lead. The multi-core results are notable because the i5-2500S has four physical cores, while the i3-4160 has only two, but the i3-4160 compensates with Hyper-Threading and a higher base clock.

Single-core performance is where the newer architecture shows its strength. In Cinebench R20 single-core, the i3-4160 scores 175 against the i5-2500S's 169, a 3.6% advantage. Cinebench R23 single-core follows the same pattern: 417 for the i3-4160 against 404 for the i5-2500S, a 3.2% lead. These consistent single-thread wins indicate that the Haswell-based i3-4160 executes instructions more efficiently per clock than the Sandy Bridge-based i5-2500S, despite the latter having a higher boost clock of 3.70 GHz.

The aggregate data reinforces the picture. The i3-4160 has an average benchmark score of 1017, while the i5-2500S sits at 1004. The i3-4160 also ranks at the 28th percentile among all CPUs, one point above the i5-2500S's 27th percentile. While neither processor is near the top of modern performance charts, the i3-4160 holds a small but real performance edge across every measured metric.

FAQ

Q: Which processor wins in multi-threaded workloads?

A: The Intel Core i3-4160 wins all three multi-core Cinebench tests. It scores 297 in R15, 1241 in R20, and 2955 in R23, versus the i5-2500S's 288, 1204, and 2867 respectively. The margin is 3.1% in each case.

Q: How does single-core performance compare?

A: The i3-4160 leads in single-core tests as well. In Cinebench R20 single-core, it scores 175 against 169, a 3.6% advantage. In Cinebench R23 single-core, it scores 417 against 404, a 3.2% lead.

Q: Does the i5-2500S have any benchmark where it wins?

A: No. The recorded data shows the i5-2500S wins zero of the five head-to-head tests. The i3-4160 wins all five.

Q: Is there a significant difference in overall performance percentiles?

A: The difference is small. The i3-4160 sits at the 28th percentile of all CPUs, while the i5-2500S sits at the 27th percentile. Their average benchmark scores are 1017 and 1004, respectively.

Q: The i5-2500S has four cores; why doesn't it win multi-threaded tests?

A: Although the i5-2500S has four physical cores, the i3-4160's two cores are backed by Hyper-Threading for four threads, and its 3.60 GHz base clock is higher. The benchmark results show the i3-4160 still manages a 3.1% lead in all multi-core tests.

Architecture Differences

The two processors come from different architectural eras. The i3-4160 uses the Haswell architecture on a 22 nm process, while the i5-2500S uses the older Sandy Bridge architecture on a 32 nm process. This node advantage translates directly to efficiency and per-clock performance.

The i3-4160 has 2 cores and 4 threads, with a 3.60 GHz base clock and no boost clock listed. The i5-2500S counters with 4 cores and 4 threads, a lower base clock of 2.70 GHz, but a boost clock of 3.70 GHz. Despite the i5's higher peak clock, the i3 still wins on single-threaded tests, showing that a newer architecture can do more with less clock speed.

Cache configurations differ notably. The i3-4160 has 3 MB of shared L3 cache, while the i5-2500S has 6 MB of shared L3 cache. Both have 64 KB of L1 cache per core and 256 KB of L2 cache per core. The larger L3 cache on the i5-2500S does not translate into a benchmark win.

The process node difference is also visible in power and die characteristics. The i3-4160 uses a 22 nm process with 1,400 million transistors on a 177 mm² die. The i5-2500S uses a 32 nm process with 1,160 million transistors on a larger 216 mm² die. The i3-4160 has a TDP of 54 W, while the i5-2500S has a TDP of 65 W.

Integrated graphics differ as well. The i3-4160 includes Intel HD 4400, while the i5-2500S includes Intel HD 2000. Both support DDR3 memory in dual-channel mode, and neither supports ECC memory. The i3-4160 uses Intel Socket 1150, while the i5-2500S uses Intel Socket 1155.

Where Each One Wins

The Intel Core i3-4160 wins in every benchmark category recorded. In single-threaded workloads, it is consistently ahead by around 3.2% to 3.6%. This makes it the better choice for lightly threaded applications such as older games, office productivity, and general desktop usage where a single core carries most of the load. Its lead in single-core Cinebench R20 (175 vs 169) and R23 (417 vs 404) confirms this.

In multi-threaded workloads, the i3-4160 also wins, but the margin is slightly smaller at exactly 3.1% across all three Cinebench multi-core tests. This is the more surprising result, given the i5-2500S's extra physical cores. The i3-4160's higher base clock and Hyper-Threading are sufficient to overcome the core-count deficit. For users running rendering or video encoding tasks, the i3-4160 will complete them faster, though the gap is modest.

The i5-2500S has no benchmark wins in the current data set. Its advantages are limited to non-benchmark characteristics: it has a larger 6 MB L3 cache and a boost clock of 3.70 GHz. However, these features do not translate into performance in the measured workloads. The i5-2500S is also an older part, released in early 2011, and is now end-of-life, while the i3-4160 was released in mid-2014 and remains active.

For anyone choosing between these two, the data points to the i3-4160 as the faster CPU. It wins every test, offers a slightly higher performance percentile, and does so with a lower TDP of 54 W versus 65 W. The i5-2500S is competitive only in that the absolute margin is small, under 4% in all tests. The single-core lead of the i3-4160 is its strongest asset, making it the better pick for everyday computing. The i5-2500S, despite having four physical cores, cannot overcome its architectural disadvantage and slower base clock.
