Analysis: Intel Core 3 305 vs Intel Core i5-14400F
Head-to-Head Benchmarks
The benchmark comparison between the Intel Core 3 305 and the Intel Core i5-14400F is heavily lopsided. Out of 17 recorded head-to-head tests, the Core i5-14400F claims 14 wins while the Core 3 305 takes only 3. The average benchmark score tells a similar story: the Core i5-14400F sits at 32279, while the Core 3 305 averages 18302, a gap of roughly 76%.
The most decisive victories for the Core i5-14400F come in multi-threaded and integer-heavy workloads. In Cinebench R23 multicore, the Core i5-14400F scores 21645 against 13123 for the Core 3 305, a 39.4% advantage. The same 39.4% delta repeats across every Cinebench test, including R15 multicore (2181 vs 1322), R15 singlecore (307 vs 186), R20 multicore (9090 vs 5511), R20 singlecore (1283 vs 777), and R23 singlecore (3055 vs 1852). This consistency indicates a uniform performance gap across both single-threaded and multi-threaded rendering workloads.
The largest single delta appears in PassMark integer math, where the Core i5-14400F scores 81524 versus 32295 for the Core 3 305, a 60.4% difference. Data compression also shows a massive gap: 315521 for the Core i5-14400F versus 146857 for the Core 3 305, a 53.5% deficit. Random string sorting follows with a 46.1% gap (32680 vs 17623). These results suggest the Core i5-14400F has substantially stronger raw arithmetic and data manipulation throughput.
The Core 3 305 does secure two notable wins in single-threaded PassMark tests. In PassMark single thread, it scores 3977 versus 3701 for the Core i5-14400F, a 7.5% advantage. The identical score appears in the duplicate PassMark singlethread test. The third win for the Core 3 305 comes in PassMark find prime numbers, where it scores 115 versus 86, a 33.7% margin. This particular result is intriguing, as it suggests the Core 3 305 handles prime number generation more efficiently despite its overall lower compute throughput.
Other PassMark tests favor the Core i5-14400F by narrower margins. Floating point math shows a 31% gap (61319 vs 42284), data encryption shows 35% (16949 vs 11019), extended instructions show 32.1% (19937 vs 13543), multithread shows 39.4% (25470 vs 15439), and physics shows 19% (1523 vs 1233).
Architecture Differences
The two processors come from fundamentally different design points. The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process node, while the Intel Core i5-14400F uses Raptor Lake-R (Raptor Lake architecture) on a 10 nm process. Both are manufactured by Intel, but the process node difference is substantial: 3 nm versus 10 nm represents multiple generational steps in transistor density.
Core counts diverge sharply. The Core 3 305 has 6 cores and 6 threads, meaning no hyperthreading. The Core i5-14400F has 10 cores and 16 threads, indicating a hybrid configuration with performance and efficiency cores. The thread count advantage of the Core i5-14400F directly explains much of its multicore benchmark dominance.
Cache hierarchies also differ significantly. The Core 3 305 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core i5-14400F has 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The L3 cache difference is particularly notable: 20 MB versus 6 MB gives the Core i5-14400F over three times the shared cache capacity.
Memory support separates the two as well. The Core 3 305 supports DDR5 and LPDDR5X with a single-channel memory bus and 59.7 GB/s bandwidth. The Core i5-14400F supports DDR4 and DDR5 with a dual-channel memory bus, though no bandwidth figure is recorded for it. The Core i5-14400F also supports ECC memory, while the Core 3 305 does not.
PCIe capabilities differ: the Core 3 305 uses Gen 4 with 6 lanes (CPU only), while the Core i5-14400F uses Gen 5 with 16 lanes (CPU only). The integrated graphics situation is reversed: the Core 3 305 includes Intel Xe3 Graphics (1 Xe), while the Core i5-14400F has no integrated graphics (listed as N/A).
Physical specifications also diverge. The Core 3 305 uses Intel BGA 1516 socket, a mobile package, while the Core i5-14400F uses Intel Socket 1700 for desktop. The die size for the Core i5-14400F is recorded at 215 mm², while no die size is listed for the Core 3 305. Both have locked multipliers.
Where Each One Wins
The Core i5-14400F dominates in nearly every compute category. Its 10 cores and 16 threads give it a decisive edge in multi-threaded workloads. The Cinebench results confirm this across all three versions (R15, R20, R23), with a consistent 39.4% advantage. PassMark multithread shows the same 39.4% delta, reinforcing that the thread count advantage translates directly to throughput.
The Core i5-14400F also wins in data-heavy tasks. Data compression shows a 53.5% advantage, integer math shows 60.4%, and random string sorting shows 46.1%. These are tasks that benefit from both high core counts and large caches, and the 20 MB L3 cache likely plays a role. Floating point math (31% advantage), data encryption (35%), extended instructions (32.1%), and physics (19%) all favor the Core i5-14400F as well.
The Core 3 305 wins in exactly three areas. PassMark single thread and singlethread (both scoring 3977 vs 3701) show a 7.5% advantage, indicating that the Core 3 305 has slightly higher per-thread performance in this specific PassMark test, despite its lower boost clock of 4.30 GHz compared to 4.70 GHz for the Core i5-14400F. The most surprising win is in PassMark find prime numbers, where the Core 3 305 scores 115 versus 86, a 33.7% margin. This suggests the Core 3 305 has a particular efficiency in prime number computation that outweighs its general performance deficit.
The single-threaded Cinebench results do not align with the PassMark single-thread result. In Cinebench R23 singlecore, the Core i5-14400F leads 3055 to 1852, a 39.4% margin. This discrepancy indicates that the PassMark single-thread test measures a different aspect of performance than Cinebench's single-core workload, and the Core 3 305's architecture handles that specific PassMark workload more efficiently.
Specification Differences

The Verdict
The benchmark data shows a clear performance hierarchy. The Intel Core i5-14400F outperforms the Intel Core 3 305 in 14 of 17 head-to-head tests, with an average benchmark score of 32279 versus 18302. The Core i5-14400F sits in the 83rd percentile of all CPUs, while the Core 3 305 sits in the 72nd percentile. The Core i5-14400F's nearest rivals include the AMD Ryzen 7 PRO 8840U (0.1% higher average score), the Intel Core i9-11900 (0.2% higher), and the Intel Core i7-12800H (0.5% higher), placing it in solid mid-range desktop territory.
The Core 3 305, by contrast, sits near the Intel Core i3-14100 (0.1% lower average score), the Intel Core 5 330 (0.2% lower), and the Intel Core 7 360 (0.4% lower), with the AMD Ryzen 5 2600E slightly behind at 0.4% lower. Its percentile ranking of 72 places it in the upper-mid range of mobile processors.
For multi-threaded workloads, rendering, data compression, and integer-heavy tasks, the Intel Core i5-14400F is clearly the stronger choice. Its 10 cores, 16 threads, 20 MB L3 cache, and 65 W TDP deliver consistent 30% to 60% advantages across nearly every recorded benchmark. The 3 nm process node of the Core 3 305 does not compensate for its lower core count and smaller cache in most workloads.
The Core 3 305 does hold specific advantages. Its single-thread PassMark score is 7.5% higher, and its prime number finding performance is 33.7% better. It also includes integrated graphics, supports LPDDR5X memory, and draws only 15 W TDP, making it suited for mobile applications where power efficiency and integrated display output matter. Its 3 nm process node and 2026 release date indicate a newer design, but the recorded data shows it does not match the Core i5-14400F in raw compute throughput.
The choice depends on workload and platform. For desktop users prioritizing multi-core performance, data throughput, and cache capacity, the Core i5-14400F is the clear winner. For mobile or low-power applications where integrated graphics, single-thread PassMark efficiency, and prime number computation are priorities, the Core 3 305 has merit despite its overall lower average score.
