Intel Core 3 305 vs Intel Core i5-14600 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive result: the Intel Core i5-14600 wins every single head-to-head comparison in the database, taking all 17 recorded tests. The Intel Core 3 305 does not secure a single victory. However, the margin of victory is not uniform, and the scale of the difference varies significantly depending on the workload.

The largest single gap appears in PassMark integer math, where the Core i5-14600 scores 117078 against the Core 3 305's 32295, a deficit of 72.4% for the Core 3 305. This indicates a massive advantage for the i5 in workloads dominated by integer arithmetic. A similarly large gap exists in data compression, where the i5-14600's 434620 score is 66.2% higher than the Core 3 305's 146857. The gap narrows somewhat in random string sorting, where the i5 leads with 48043 versus 17623, a 63.3% advantage, and in data encryption, where the i5's 25082 beats the Core 3 305's 11019 by 56.1%.

Across the Cinebench suite, the pattern is consistent. In Cinebench R23 multicore, the i5-14600 scores 30464 while the Core 3 305 scores 13123, a 56.9% deficit. The same percentage deficit appears in Cinebench R15 multicore (3070 versus 1322) and Cinebench R20 multicore (12794 versus 5511). Single-core performance shows a slightly larger relative gap in the older Cinebench tests. In Cinebench R15 single-core, the i5's 433 score is 57% higher than the Core 3 305's 186, and in Cinebench R20 single-core the i5's 1806 beats 777 by the same 57%. In Cinebench R23 single-core, the i5's 4300 leads by 56.9% over 1852.

The narrowest margin in the entire comparison appears in PassMark single-thread performance. Here the i5-14600 scores 4167 versus the Core 3 305's 3977, a lead of only 4.6%. This is a notable result, as it shows that in purely single-threaded integer workloads the two processors are much closer than in any other test. The same 4.6% margin appears in the duplicate PassMark singlethread entry.

Other workloads show intermediate gaps. PassMark floating point math gives the i5-14600 an 85759 score versus 42284, a 50.7% advantage. Extended instructions show the i5 leading by 47.3% (25674 versus 13543). The physics test shows a 47.1% gap (2330 versus 1233). Find prime numbers has the smallest gap outside of single-threaded tests, with the i5's 155 beating the Core 3 305's 115 by 25.8%. PassMark multithread shows the i5 ahead by 56.9%, scoring 35848 versus 15439.

Architecture Differences

The two processors are built on fundamentally different architectures. The Intel Core 3 305 uses the Wildcat Lake codename and belongs to the Core 3 generation, built on a 3 nm process node. The Intel Core i5-14600 uses the Raptor Lake-R codename, belongs to the Raptor Lake Refresh architecture, and is built on a 10 nm process node. Both are manufactured by Intel, but the process difference is substantial and explains some of the efficiency and thermal distinctions between them.

The core configurations differ sharply. The Core 3 305 has 6 cores and 6 threads, indicating no hyper-threading. The Core i5-14600 has 14 cores and 20 threads, indicating a hybrid configuration of performance cores and efficient cores with hyper-threading on the performance cores. This accounts for the large multicore performance gap observed in the Cinebench suite.

Cache hierarchies also diverge. The Core 3 305 has a 192 KB L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core i5-14600 lists 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The i5's larger L3 allocation is consistent with its leadership in cache-sensitive workloads such as data compression and random string sorting.

Memory support differs as well. The Core 3 305 supports DDR5 and LPDDR5X memory over a single-channel bus, with a recorded memory bandwidth of 59.7 GB/s. The Core i5-14600 supports DDR4 and DDR5 over a dual-channel bus, with no memory bandwidth figure recorded in the database. ECC memory support is present on the i5-14600 but absent on the Core 3 305.

PCIe connectivity is another differentiator. The Core 3 305 provides PCIe Gen 4 with 6 CPU lanes, while the Core i5-14600 provides PCIe Gen 5 with 16 CPU lanes. The integrated graphics also differ: the Core 3 305 uses Intel Xe3 Graphics with 1 Xe unit, while the Core i5-14600 uses UHD Graphics 770.

The market segments are distinct. The Core 3 305 is a mobile processor using the Intel BGA 1516 socket, while the Core i5-14600 is a desktop processor using Intel Socket 1700. The die size is recorded only for the i5-14600 at 257 mm². Both processors have locked multipliers, and both are currently in active production.

Specification Differences

The two processors differ in nearly every specification category. Core count: 6 versus 14. Thread count: 6 versus 20. Base clock: 1.50 GHz for the Core 3 305 versus 2.70 GHz for the i5-14600. Boost clock: 4.30 GHz versus 5.20 GHz. Thermal design power: 15 watts versus 65 watts. These figures show that the i5-14600 operates at higher clocks and consumes substantially more power.

Process node: 3 nm for the Core 3 305 versus 10 nm for the i5-14600. Socket: Intel BGA 1516 versus Intel Socket 1700. Memory bus: single-channel versus dual-channel. ECC support: false versus true. PCIe generation and lanes: Gen 4 with 6 lanes versus Gen 5 with 16 lanes. Integrated graphics: Intel Xe3 Graphics (1 Xe) versus UHD Graphics 770. Market segment: mobile versus desktop. Release date: the Core 3 305 released on 2026-04-15, while the i5-14600 released on 2024-01-07. Launch MSRP: the Core 3 305 at $309, the i5-14600 at $255. Part numbers: SAE3L versus SRN44.

The cache specifications are not directly comparable as recorded. The Core 3 305 lists total L1 of 192 KB, total L2 of 2.5 MB, and shared L3 of 6 MB. The i5-14600 lists per-core L1 of 80 KB, per-core L2 of 2 MB, and shared L3 of 24 MB. The i5-14600 also has a recorded die size of 257 mm², while no die size is recorded for the Core 3 305. Memory bandwidth is recorded for the Core 3 305 at 59.7 GB/s but not for the i5-14600. The i5-14600 supports DDR4 in addition to DDR5, while the Core 3 305 supports DDR5 and LPDDR5X.

The Verdict

The recorded data shows a clear performance hierarchy. The Intel Core i5-14600 dominates every benchmark in the head-to-head comparison, with advantages ranging from 4.6% in single-threaded PassMark tests to 72.4% in integer math. Its average benchmark score of 44889 places it in the 89th percentile, well above the Core 3 305's 18302 average and 72nd percentile.

For workloads that depend heavily on multi-core throughput, integer arithmetic, data compression, or encryption, the i5-14600 is the appropriate choice. The 14 cores and 20 threads provide a structural advantage that the Core 3 305's 6 cores and 6 threads cannot match. The i5-14600 also offers dual-channel memory support, ECC memory capability, PCIe Gen 5 with 16 lanes, and a higher boost clock of 5.20 GHz.

The Core 3 305 does have its own strengths in the data. Its 3 nm process node and 15 watt TDP make it a far more efficient design, suited to mobile platforms on the Intel BGA 1516 socket. It supports LPDDR5X memory, which the i5-14600 does not. In single-threaded PassMark performance, the gap narrows to 4.6%, meaning that light, single-threaded tasks will not show a dramatic difference. Its nearest rivals in the database, such as the Intel Core i3-14100, are within 0.1% of its average score, confirming that it competes in a lower performance tier.

The database indicates that the i5-14600 is the stronger processor for compute-heavy desktop workloads, while the Core 3 305 targets a different segment entirely. The choice between them rests on the platform: desktop users with Socket 1700 requirements and a need for high multi-core throughput should select the i5-14600, while mobile designs prioritizing low power consumption on a 3 nm process align with the Core 3 305. The data does not suggest any scenario where the Core 3 305 outperforms the i5-14600 in raw benchmark performance.
