CPU Comparison

The Intel Core i3-4160 and Intel Core i3-4340 are two nearly identical Haswell-era desktop processors, both built on the 22 nm process and featuring 2 cores and 4 threads. The data shows they share the same 3.60 GHz base clock, 54 W TDP, and Intel Socket 1150 compatibility. The critical differentiators are the L3 cache size, the integrated graphics solution, and the release date. Benchmark results indicate that the Core i3-4340, released earlier in 2013, holds a consistent, albeit narrow, performance lead over the newer Core i3-4160 across all tested Cinebench workloads, with the 4340 winning all five head-to-head comparisons.

FAQ

Q: Which processor is faster in multi-core performance?

A: The Intel Core i3-4340 wins every multi-core benchmark. In Cinebench R15 multicore, it scores 300 versus the i3-4160's 297, a 1% difference. In Cinebench R20 multicore, the 4340 scores 1252 against 1241, a 0.9% lead. The gap widens slightly in Cinebench R23 multicore, with the 4340 scoring 2983 versus 2955, also a 0.9% difference.

Q: Is there any difference in single-core performance?

A: Yes, but it is minimal. The i3-4340 edges out the i3-4160 in both single-core tests. In Cinebench R20 singlecore, the score is 176 versus 175 (0.6% difference). In Cinebench R23 singlecore, the 4340 scores 421 against the 4160's 417, a 1% advantage. Both processors share the same 3.60 GHz base clock, so this minor gap likely stems from other architectural differences.

Q: Do these CPUs have the same integrated graphics?

A: No, they do not. The Intel Core i3-4160 features the Intel HD 4400, while the Intel Core i3-4340 is equipped with the Intel HD 4600. This is a notable specification difference, as the 4340's graphics solution is a step up in Intel's integrated graphics lineup.

Q: How much L3 cache does each processor have?

A: The Intel Core i3-4340 has 4 MB of shared L3 cache, while the Intel Core i3-4160 has 3 MB of shared L3 cache. This 1 MB difference is the most significant architectural distinction between the two parts and likely contributes to the 4340's benchmark advantage.

Q: What is the release timeline for these two chips?

A: The Intel Core i3-4340 was released on 2013-08-31. The Intel Core i3-4160 was released later, on 2014-07-20. This means the i3-4160 is the newer product, despite being positioned slightly lower in the performance hierarchy based on the benchmark data.

Q: How do these processors compare to other CPUs in the database?

A: Both processors sit at the 28th percentile when compared to all CPUs in the database. The i3-4160 has an average benchmark score of 1017, while the i3-4340 has an average score of 1026. The i3-4160's nearest rival is the Intel Core i3-4330 with an average score of 1020, a 0.3% difference, while the i3-4340's closest competitor is the Intel Processor N150 with a score of 1025.

Architecture Differences

Both the Intel Core i3-4160 and the Intel Core i3-4340 are built on Intel's Haswell architecture, using the same 22 nm process node. They share the same 1,400 million transistor count and a 177 mm² die size, indicating they are fundamentally the same silicon. The core configuration is identical: 2 physical cores with Hyper-Threading, yielding 4 threads. The base clock is also the same at 3.60 GHz, and neither processor has a boost clock. Both support dual-channel DDR3 memory and PCIe Gen 3.

The primary architectural divergence lies in the cache hierarchy. The i3-4160 has 3 MB of shared L3 cache, whereas the i3-4340 has 4 MB. Both have the same 64 KB L1 cache and 256 KB L2 cache per core. This extra 1 MB of L3 cache on the 4340 is a meaningful difference, as it allows more frequently accessed data to be stored closer to the cores, reducing latency and improving performance in cache-sensitive workloads.

Another key difference is the integrated GPU. The i3-4160 ships with the Intel HD 4400, while the i3-4340 includes the Intel HD 4600. While the FACT PACK does not provide performance metrics for these iGPUs, the HD 4600 is a higher-tier part than the HD 4400. Finally, the release dates differ, with the i3-4340 launching on 2013-08-31 and the i3-4160 on 2014-07-20, suggesting the 4160 is a later, possibly cost-optimized, refresh of the same design.

Head-to-Head Benchmarks

The head-to-head data is remarkably one-sided, with the Intel Core i3-4340 winning all five benchmark tests. The largest margin of victory is a 1% lead in Cinebench R15 multicore, where the 4340 scores 300 against the 4160's 297. This same 1% margin appears again in Cinebench R23 singlecore, with scores of 421 and 417 respectively.

In the Cinebench R20 suite, the 4340's advantage is slightly smaller. For multicore, it scores 1252 versus 1241, a 0.9% delta. For singlecore, the scores are 176 versus 175, a 0.6% delta. The Cinebench R23 multicore test shows the 4340 winning with a score of 2983 against 2955, another 0.9% advantage.

The consistency of these results is striking. The i3-4340 does not lose a single test, and its wins are remarkably uniform, ranging from 0.6% to 1%. This pattern strongly suggests that the performance gap is not a result of clock speed variation, both are locked at 3.60 GHz, but rather a systematic advantage conferred by the larger 4 MB L3 cache on the 4340. The data implies that the i3-4340 is the more capable processor in every measured scenario, even if the absolute difference is small.

Specification Differences

The following table outlines the key specification differences between the two processors, based solely on the FACT PACK data.

| Specification | Intel Core i3-4160 | Intel Core i3-4340 |

| :--- | :--- | :--- |

| L3 Cache | 3 MB (shared) | 4 MB (shared) |

| Integrated Graphics | Intel HD 4400 | Intel HD 4600 |

| Release Date | 2014-07-20 | 2013-08-31 |

| Part Number | Not specified | SR1NL |

| Production Status | Active | Not specified |

All other specifications are identical. Both have 2 cores, 4 threads, a 3.60 GHz base clock, no boost clock, a 54 W TDP, and use the Intel Socket 1150. They share the same Haswell architecture, 22 nm process, 1,400 million transistors, and 177 mm² die size. Memory support is DDR3 with a dual-channel bus, and both lack ECC memory support. Neither processor has an unlocked multiplier, and both are marked as Desktop segment parts.

Where Each One Wins

Based on the benchmark data, the Intel Core i3-4340 is the clear winner in all performance categories tested. It dominates the multi-core tests, taking a 1% lead in Cinebench R15 and a 0.9% lead in both Cinebench R20 and R23 multicore. This makes it the better choice for any workload that leverages multiple threads, such as video encoding or 3D rendering, even if the margin is slim.

The i3-4340 also wins the single-core tests, with a 0.6% advantage in Cinebench R20 singlecore and a 1% edge in Cinebench R23 singlecore. This suggests it would be marginally better for lightly-threaded applications like older games or everyday productivity tasks. The i3-4340 also has the advantage of the Intel HD 4600 integrated graphics, which is a higher-tier solution than the HD 4400 found in the i3-4160.

The Intel Core i3-4160 does not win any benchmark in the head-to-head comparison. Its only potential advantages are its "Active" production status and its later release date. The data does not show any scenario where the i3-4160 outperforms the i3-4340. Its nearest rival, the Intel Core i3-4330, scores 1020, which is slightly higher than the 4160's 1017 average score, further reinforcing that the 4160 sits at the lower end of this performance tier.

The Verdict

The data is unambiguous: the Intel Core i3-4340 is the superior processor. It wins every single head-to-head benchmark against the i3-4160, with margins ranging from 0.6% to 1%. For users seeking the best possible performance from this Haswell dual-core platform, the i3-4340 is the definitive choice. Its larger 4 MB L3 cache and superior Intel HD 4600 graphics make it a more capable part across both CPU and iGPU workloads.

The Intel Core i3-4160, while not a poor performer, it still holds the 28th percentile among all CPUs, is strictly outclassed by its sibling. Its "Active" production status might suggest availability, but the performance data offers no reason to prefer it over the i3-4340. The average benchmark scores reinforce this, with the 4340 scoring 1026 against the 4160's 1017.

In summary, the choice is clear. If the option exists, the Intel Core i3-4340 is the processor to pick. It offers the same core configuration, clock speed, and TDP as the 4160, but with a tangible performance advantage that is consistent across all tested applications. The i3-4160 is only relevant if the i3-4340 is unavailable, as it delivers no performance benefits of its own. The 4340's victory is a textbook case of a higher-tier cache configuration and better integrated graphics decisively outweighing a later release date.
