Intel Core 5 315 vs Intel Core i9-14900KS Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core i9-14900KS across all 17 head-to-head benchmark comparisons. The Intel Core 5 315 does not register a single win in any test. The margins, however, are not uniform; they range from a modest 16.5% deficit in single-thread workloads to an overwhelming 85.1% gap in integer math.

In Cinebench R23 multi-core, the Core i9-14900KS scores 50995 against the Core 5 315's 12981, a 74.5% advantage. The single-core R23 result follows the same pattern: 7199 versus 1832, a 74.6% delta. Cinebench R15 and R20 tell an identical story. The R15 multi-core test shows 5140 against 1308, and R20 multi-core shows 21417 against 5452. Every Cinebench variant, whether single-core or multi-core, lands within a narrow band of 74.5% to 74.6% in favor of the i9-14900KS. This consistency suggests the performance gap scales evenly across rendering workloads regardless of the benchmark version.

The PassMark suite reveals where the gap widens and narrows. The smallest deficit for the Core 5 315 appears in PassMark single-thread and singlethread tests, where both record 4021 against the i9-14900KS's 4815. That 16.5% gap is the closest the Core 5 315 comes to parity anywhere in the data. The largest gap appears in PassMark integer math: 31690 versus 212644, a 85.1% deficit. Data compression shows an 81.8% gap (146143 versus 803368), and random string sorting shows an 80.5% gap (17551 versus 89789). Floating point math sits at 72.4% (42441 versus 153975), and extended instructions at 71.1% (13143 versus 45524). Encryption trails by 76.7% (11119 versus 47717).

The multi-thread PassMark result is 15272 for the Core 5 315 and 60012 for the i9-14900KS, a 74.6% gap that mirrors the Cinebench multi-core deltas. The physics test shows 1163 versus 3381, a 65.6% gap. The prime number search is the outlier at 54.1% (112 versus 244), the second-smallest margin after single-thread performance.

The average benchmark score for the i9-14900KS is 81127, placing it in the 96th percentile of all CPUs in the database. The Core 5 315 averages 18188, sitting in the 72nd percentile.

Architecture Differences

The two processors come from fundamentally different design points. The Intel Core 5 315 uses the Wildcat Lake architecture on a 3 nm process node and is soldered to the Intel BGA 1516 socket. It is a mobile part with 6 cores and 6 threads. The Intel Core i9-14900KS uses Raptor Lake-R, built on a 10 nm node, and fits the Intel Socket 1700. It is a desktop part with 24 cores and 32 threads. The i9-14900KS's die size is recorded at 257 mm²; no die size is listed for the Core 5 315.

Cache organization differs sharply. The Core 5 315 carries 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The i9-14900KS lists 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The per-core L1 and L2 figures for the i9-14900KS scale with its 24 cores, producing a substantially larger aggregate cache footprint. The shared L3 alone is six times larger than the Core 5 315's total L3.

Memory support separates the two as well. The Core 5 315 supports DDR5 and LPDDR5X over a single-channel memory bus with 59.7 GB/s of bandwidth. The i9-14900KS supports DDR4 and DDR5 over a dual-channel bus; its memory bandwidth is not recorded in the database. ECC memory is supported on the i9-14900KS but not on the Core 5 315.

PCIe connectivity differs by generation and lane count. The Core 5 315 provides Gen 4 with 6 CPU lanes. The i9-14900KS provides Gen 5 with 16 CPU lanes. The integrated graphics also differ: the Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores, while the i9-14900KS uses UHD Graphics 770.

The production status for both is active. The Core 5 315 launched on 2026-04-15 with a launch MSRP of $340. The i9-14900KS launched on 2024-03-13 with a launch MSRP of $689. The i9-14900KS has an unlocked multiplier; the Core 5 315 does not. The part numbers are SAEFC for the Core 5 315 and SRN7R for the i9-14900KS.

Where Each One Wins

Based on the benchmark data, the i9-14900KS wins every workload category recorded. There is no test in the database where the Core 5 315 takes the lead. The i9-14900KS's 24 cores and 32 threads dominate multi-threaded workloads. Its Cinebench R23 multi-core score of 50995 is 74.5% ahead, and its PassMark multi-thread score of 60012 is 74.6% ahead. The 36 MB of shared L3 and dual-channel memory support provide the resources for sustained throughput in rendering and compression tasks.

The i9-14900KS also wins single-thread workloads, though by a smaller margin. Its PassMark single-thread score of 4815 beats the Core 5 315's 4021 by 16.5%. The Cinebench R23 single-core margin is identical in percentage terms at 74.6%, but the absolute gap is smaller because the scores are lower. The boost clock difference explains part of this: the i9-14900KS boosts to 6.20 GHz, while the Core 5 315 boosts to 4.40 GHz.

The Core 5 315's strongest relative showing is in prime number finding, where its 112 score trails by only 54.1%. This suggests its 6 cores, each with dedicated execution resources, can keep pace proportionally better in a workload that does not scale perfectly with core count. Still, it loses the test outright.

The i9-14900KS's largest advantage appears in integer math, where its 212644 score is 85.1% above the Core 5 315's 31690. This workload benefits heavily from the combination of more cores, higher clocks, and larger caches. Data compression shows an 81.8% gap, random string sorting an 80.5% gap, and encryption a 76.7% gap. These are all throughput-oriented tasks where the i9-14900KS's architecture provides a decisive edge.

The 72nd percentile ranking of the Core 5 315 places it above the median CPU in the database, but its nearest rivals are mid-range parts like the Intel Core i7-9700 and AMD Ryzen 7 5700U. The i9-14900KS's 96th percentile ranking puts it near the top of the entire database, with rivals like the Intel Xeon w5-3535X and AMD Ryzen 9 8940HX. The average benchmark scores, 81127 versus 18188, reflect a processor designed for entirely different performance tiers and power envelopes.
