Intel Core 5 315 vs Intel Core i5-14450HX Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall advantage for the Intel Core i5-14450HX, which wins 14 of the 17 recorded comparisons. The Intel Core 5 315 wins 3 tests, all in the PassMark suite. The most lopsided result is in PassMark integer math, where the Core i5-14450HX scores 78,330 against 31,690 for the Core 5 315, a delta of 59.5%. This is the single largest performance gap in the entire dataset.

The Cinebench results are uniformly in favor of the Core i5-14450HX, with every test showing a 35.4% advantage. In Cinebench R23 multicore, the Core i5-14450HX scores 20,108 versus 12,981 for the Core 5 315. The single-core R23 result follows the same pattern: 2,838 against 1,832, again a 35.4% delta. This consistency across all three Cinebench versions (R15, R20, R23) and both single-core and multicore modes indicates a systematic performance differential rather than workload-specific variation.

The PassMark data compression test shows the Core i5-14450HX at 278,538 versus 146,143, a 47.5% gap. Random string sorting favors the Core i5-14450HX by 40.6% (29,565 vs 17,551). Floating point math shows a 26.9% advantage for the Core i5-14450HX (58,037 vs 42,441). Data encryption is closer but still favors the Core i5-14450HX by 28.6% (15,574 vs 11,119). Extended instructions show a 23.6% edge for the Core i5-14450HX (17,207 vs 13,143). The multithreaded PassMark score favors the Core i5-14450HX by 35.5% (23,680 vs 15,272), and the physics test shows a 21.2% advantage (1,475 vs 1,163).

The Intel Core 5 315 claims three wins. The PassMark single-thread test shows the Core 5 315 at 4,021 versus 3,643 for the Core i5-14450HX, a 10.4% advantage. This result appears twice in the dataset under both "passmark_single_thread" and "passmark_singlethread" with identical scores. The other win is in PassMark find prime numbers, where the Core 5 315 scores 112 against 98, a 14.3% edge. These wins are narrow compared to the Core i5-14450HX's margins, and they are confined to specific integer workloads.

The average benchmark score in the database reflects the overall picture: the Core i5-14450HX averages 32,040 across all recorded tests, while the Core 5 315 averages 18,188. The Core i5-14450HX sits at the 82nd percentile of all CPUs in the database, compared to the 72nd percentile for the Core 5 315.

Architecture Differences

The two processors diverge fundamentally in their core configurations. The Intel Core 5 315 uses 6 cores and 6 threads with no hyper-threading, while the Intel Core i5-14450HX uses 10 cores and 16 threads. The Core i5-14450HX's thread count is more than double its core count, indicating that hyper-threading is active across all cores. The Core 5 315 has a 1:1 core-to-thread ratio, meaning each physical core handles exactly one thread.

Clock speeds differ substantially. The Core 5 315 has a base clock of 1.50 GHz and a boost clock of 4.40 GHz. The Core i5-14450HX starts at 2.40 GHz base and reaches 4.80 GHz boost. The Core i5-14450HX thus carries both a higher base frequency and a higher maximum boost frequency, which contributes to its dominant multicore and single-core results.

The process node represents a significant manufacturing difference. The Core 5 315 is built on a 3 nm process, while the Core i5-14450HX uses a 10 nm process. Both are fabricated by Intel, but the 3 nm node is newer and denser. The Core i5-14450HX has a published die size of 257 mm², while the Core 5 315 has no die size recorded in the database.

Cache hierarchies are structured differently. The Core 5 315 has a 192 KB L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core i5-14450HX specifies L1 at 80 KB per core, L2 at 2 MB per core, and 20 MB of shared L3 cache. The Core i5-14450HX's larger L3 (20 MB vs 6 MB) and per-core L2 allocation give it a substantial cache advantage for workloads that benefit from larger working sets.

Memory support also differs. The Core 5 315 supports DDR5 and LPDDR5X with a single-channel memory bus, providing 59.7 GB/s of bandwidth. The Core i5-14450HX supports DDR4 and DDR5 with a dual-channel memory bus. The Core i5-14450HX has no memory bandwidth figure recorded in the database, but its dual-channel configuration is architecturally superior to the single-channel setup of the Core 5 315. ECC memory support is present on the Core i5-14450HX but absent on the Core 5 315.

PCIe connectivity differs markedly. The Core 5 315 provides Gen 4 with 6 lanes (CPU only), while the Core i5-14450HX provides Gen 5 with 16 lanes (CPU only). The Core i5-14450HX offers both a newer PCIe generation and nearly three times the lane count. Integrated graphics also differ: the Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores, while the Core i5-14450HX uses UHD Graphics 710.

The sockets are incompatible. The Core 5 315 uses Intel BGA 1516, while the Core i5-14450HX uses Intel BGA 1964. The Core i5-14450HX has an unlocked multiplier, whereas the Core 5 315 does not. The Core i5-14450HX is part of the Core 14th Gen series with a Raptor Lake-HX Refresh codename, while the Core 5 315 belongs to the Core 5 (Wildcat Lake) generation. The Core 5 315 has a recorded launch MSRP of $340.

Where Each One Wins

The Intel Core i5-14450HX wins in every multicore-heavy workload and in the majority of single-threaded tests. Its 10 cores and 16 threads provide a clear advantage in Cinebench R15, R20, and R23 multicore tests, all showing a 35.4% delta. PassMark multithread confirms this with a 35.5% advantage. The data compression test, which scales well with core count and cache, favors the Core i5-14450HX by 47.5%. Integer math shows the largest gap at 59.5%, reflecting the Core i5-14450HX's superior per-core integer throughput combined with more cores.

The Core i5-14450HX also wins in single-core Cinebench tests by 35.4%, which is notable because the Core 5 315 wins the PassMark single-thread test by 10.4%. This apparent contradiction suggests that the Cinebench single-core workload responds more to the Core i5-14450HX's higher boost clock (4.80 GHz vs 4.40 GHz) and larger cache, while the PassMark single-thread test favors the Core 5 315's architecture or memory subsystem. The Core 5 315's single-thread PassMark score of 4,021 is the only single-core metric where it leads.

The Core 5 315 wins in find prime numbers, scoring 14.3% higher. This workload is highly dependent on integer operations and memory latency, and the Core 5 315's 3 nm process may provide an advantage in this specific instruction pattern. However, this is a narrow win in a single PassMark subtest, and it does not offset the broader multicore dominance of the Core i5-14450HX.

For applications that are heavily multithreaded, such as video rendering, compilation, and scientific computing, the data strongly favors the Core i5-14450HX. Its 16 threads and 20 MB of L3 cache provide the resources needed for parallel workloads. The Core 5 315, with 6 threads and 6 MB of L3, is better suited to light workloads where its single-thread PassMark advantage and lower power envelope are relevant. The Core 5 315 has a TDP of 15 W versus 55 W for the Core i5-14450HX, which suggests the Core 5 315 is designed for power-constrained environments despite its performance deficits.
