Intel Core 3 305 vs Intel Core i9-14900 Comparison

Head-to-Head Benchmarks

The data is unequivocal: the Intel Core i9-14900 wins every single head-to-head benchmark in the database, taking all 17 recorded comparisons. The Core 3 305 does not secure a single victory in any measured workload, which makes this comparison less a contest and more a demonstration of the performance gulf between a mobile-focused entry processor and a desktop flagship.

The largest margin comes in PassMark integer math, where the Core i9-14900 scores 175010 against the Core 3 305's 32295, a delta of -81.5% for the smaller chip. That means the Core i9-14900 delivers roughly five times the integer throughput. Data compression shows a similar story: 550271 versus 146857, a -73.3% gap. The Core i9-14900 also dominates in random string sorting (61060 versus 17623, -71.1%), data encryption (33540 versus 11019, -67.1%), and floating-point math (120262 versus 42284, -64.8%).

Multicore rendering benchmarks reinforce the pattern. In Cinebench R15 multicore, the Core i9-14900 scores 4793 against 1322 for the Core 3 305, a -72.4% difference. Cinebench R20 multicore shows 15910 versus 5511 (-65.4%), and Cinebench R23 multicore shows 31070 versus 13123 (-57.8%). The PassMark multithread test follows suit: 44578 versus 15439 (-65.4%). The Core i9-14900 also wins the physics test 2486 to 1233 (-50.4%) and the prime number test 188 to 115 (-38.8%).

Single-core results narrow the gap considerably, but the Core i9-14900 still leads across the board. In PassMark single-thread, the margin is just -8% (4323 versus 3977). Cinebench R23 single-core shows -16.3% (2212 versus 1852). Cinebench R15 single-core shows -41% (315 versus 186), and Cinebench R20 single-core shows -65.4% (2245 versus 777). Even in the closest test, the Core i9-14900 maintains a clear advantage.

Where Each One Wins

Given that the Core i9-14900 wins all 17 benchmarks, the use-case split is straightforward. The Core i9-14900 is the choice for every workload represented in the database. Its multicore leads are particularly pronounced in integer-heavy tasks, compression, encryption, and rendering, where the -65% to -81% deltas indicate a processor capable of far greater parallel throughput.

The Core 3 305 does not win any category, but its relative competitiveness in single-threaded PassMark testing (-8%) suggests that for lightly threaded daily workloads, the gap is modest rather than massive. Still, the Core i9-14900 leads even there, so no workload category favors the Core 3 305.

The average benchmark score tells the same story. The Core i9-14900 sits at 58115, placing it in the 92nd percentile of all CPUs in the database. The Core 3 305 averages 18302, which lands in the 72nd percentile. The Core i9-14900's nearest rivals include the Intel Xeon Platinum 8260M (-0.4% delta), AMD Ryzen 7 9850X3D (-0.5%), and Intel Xeon w5-2545 (-0.7%). The Core 3 305's nearest rivals include the Intel Core i3-14100 (-0.1%), Intel Core 5 330 (-0.2%), and Intel Core 7 360 (-0.4%). These rival clusters confirm that the Core 3 305 competes in a much lower performance tier.

Architecture Differences

The two processors come from different Intel design generations. The Core i9-14900 uses the Raptor Lake architecture, specifically the Raptor Lake-R codename, part of the Core 14th Gen series.

The Verdict

The benchmark data indicates a decisive victory for the Intel Core i9-14900 across all 17 recorded tests. Its 24 cores and 32 threads, combined with a 5.80 GHz boost clock and 36 MB of L3 cache, deliver multicore performance that ranges from roughly 1.4 times to 5 times that of the Core 3 305, depending on the workload. The Core i9-14900 also holds a single-thread lead in every test, though the margin narrows to -8% in PassMark single-thread.

The Core 3 305 is built on a newer 3 nm process and draws far less power at 15 W TDP, making it suited for mobile systems where efficiency matters. It also supports LPDDR5X memory, which is typical for thin-and-light laptops. However, the database shows no benchmark category in which it outperforms the Core i9-14900.

For users selecting a desktop processor for demanding multi-threaded workloads such as rendering, compression, encryption, or integer-heavy computation, the Core i9-14900 is the clear choice based on the recorded data. For mobile deployments where the 6-core, 6-thread configuration and 15 W TDP are sufficient, the Core 3 305 provides a functional option, but it cannot match the Core i9-14900 in any measured metric. The percentile rankings reinforce this: 92nd for the Core i9-14900 versus 72nd for the Core 3 305.
