Intel Core 5 315 vs Intel Core i9-14900 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance advantage for the Intel Core i9-14900 across every benchmark in the comparison. Out of 17 head-to-head tests, the Core i9-14900 wins all 17, with the Core 5 315 recording zero wins. The average benchmark score for the Core i9-14900 is 58115, placing it in the 92nd percentile of all CPUs, while the Core 5 315 averages 18188, which sits in the 72nd percentile.

The largest gap appears in PassMark integer math. The Core i9-14900 scores 175010 against 31690 for the Core 5 315, a delta of -81.9%, meaning the Core i9-14900 is roughly 4.5 times faster in this workload. Data compression shows a similar pattern: 550271 versus 146143, a -73.4% delta. These two tests indicate that the Core i9-14900's advantage grows substantially in workloads that scale with core count and parallel execution.

Multi-core rendering benchmarks reinforce this trend. In Cinebench R23 multicore, the Core i9-14900 delivers 31070 points against 12981 for the Core 5 315, a -58.2% delta. Cinebench R20 multicore shows 15910 versus 5452, a -65.7% delta, and Cinebench R15 multicore shows 4793 versus 1308, a -72.7% delta. The consistent multi-core gap across all three Cinebench versions indicates that the Core i9-14900's 24 cores and 32 threads provide a substantial throughput advantage over the Core 5 315's 6 cores and 6 threads.

Single-core performance tells a more nuanced story. The Core i9-14900 still wins every single-core test, but the margins are considerably smaller. In Cinebench R23 single-core, the Core i9-14900 scores 2212 against 1832, a -17.2% delta. PassMark single-thread shows 4323 versus 4021, a -7% delta. Cinebench R15 single-core shows 315 versus 184, a -41.6% delta, and Cinebench R20 single-core shows 2245 versus 769, a -65.7% delta. The smaller delta in PassMark single-thread and Cinebench R23 single-core suggests that the Core 5 315's Wildcat Lake architecture, despite having far fewer cores, can approach the Core i9-14900 in lightly threaded tasks.

Encryption and extended instruction workloads also favor the Core i9-14900 decisively. PassMark data encryption shows 33540 versus 11119, a -66.8% delta. PassMark extended instructions show 30624 versus 13143, a -57.1% delta. PassMark floating point math shows 120262 versus 42441, a -64.7% delta. PassMark find prime numbers shows 188 versus 112, a -40.4% delta, and PassMark random string sorting shows 61060 versus 17551, a -71.3% delta. PassMark physics shows 2486 versus 1163, a -53.2% delta, and PassMark multithread shows 44578 versus 15272, a -65.7% delta.

Where Each One Wins

The Core i9-14900 wins in every measured category, so the useful analysis is where its advantage is largest and where it narrows. The biggest deltas, exceeding 70%, appear in integer math (-81.9%), data compression (-73.4%), Cinebench R15 multicore (-72.7%), and random string sorting (-71.3%). These are all heavily multi-threaded workloads that exploit the Core i9-14900's 24 cores and 32 threads. The Core i9-14900 also holds a decisive edge in data encryption (-66.8%), Cinebench R20 multicore (-65.7%), PassMark multithread (-65.7%), floating point math (-64.7%), and Cinebench R23 multicore (-58.2%).

The Core 5 315 comes closest in single-threaded tests. PassMark single-thread shows only a -7% delta, and Cinebench R23 single-core shows -17.2%. These are the only two tests where the Core 5 315 stays within 20% of the Core i9-14900. In Cinebench R15 single-core the delta is -41.6%, and in Cinebench R20 single-core it is -65.7%, which suggests that the Core 5 315's single-core performance is inconsistent across different rendering engines. The Core 5 315's PassMark single-thread score of 4021 is respectable for a mobile processor, but it still trails the Core i9-14900's 4323.

For workloads that depend primarily on single-core speed, such as legacy applications or lightly threaded tasks, the Core 5 315 can operate close to the Core i9-14900's level. However, for any workload that scales across cores, the Core i9-14900 pulls ahead by a wide margin. The data shows that the Core 5 315 is best suited for scenarios where power efficiency and portability matter more than raw throughput, while the Core i9-14900 is designed for sustained multi-threaded performance in desktop environments.
