Intel Core 5 315 vs Intel Core i5-14500HX Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall performance advantage for the Intel Core i5-14500HX, which wins 15 of the 17 recorded head-to-head comparisons. The Intel Core 5 315 claims only 2 wins, both in single-threaded PassMark tests. The margin of victory for the Core i5-14500HX is substantial across nearly every workload category, though the Core 5 315 does demonstrate a notable strength in one specific area.

In Cinebench testing, the Core i5-14500HX dominates across all six recorded runs. In Cinebench R23 multicore, the Core i5 scores 24234 against 12981 for the Core 5 315, a delta of -46.4%. The single-core Cinebench R23 result shows a similar gap: 3421 versus 1832, also -46.4%. Cinebench R20 multicore delivers 10178 against 5452 (-46.4%), while R20 single-core records 1436 versus 769 (-46.4%). Cinebench R15 multicore shows 2442 against 1308 (-46.4%), and R15 single-core records 344 versus 184 (-46.5%). The consistency of the delta across every Cinebench iteration indicates a fundamental throughput difference rather than a workload-specific quirk.

PassMark integer math produces the largest single margin in the entire comparison. The Core i5-14500HX scores 95584 against 31690 for the Core 5 315, a delta of -66.8%. This is the widest gap recorded in any test. Data compression follows with 333851 versus 146143 (-56.2%), and random string sorting shows 36219 versus 17551 (-51.5%). PassMark multithread delivers 28508 versus 15272 (-46.4%), a margin that mirrors the Cinebench multicore results almost exactly.

The Core i5-14500HX also leads in floating-point math with 69442 against 42441 (-38.9%), physics with 1911 versus 1163 (-39.1%), and data encryption with 19502 versus 11119 (-43.0%). Extended instructions show 20019 versus 13143 (-34.3%). The smallest Core i5 win comes in the find prime numbers test, where it scores 130 against 112, a delta of only -13.8%.

The Core 5 315 secures its single clear victory in the PassMark single-thread test, scoring 4021 against 3629 for the Core i5-14500HX, a positive delta of 10.8%. This result appears in both passmark_single_thread and passmark_singlethread entries, confirming the same measurement. This means the Core 5 315 delivers roughly 11% higher single-threaded PassMark performance despite the Core i5's higher boost clock, a result that warrants attention in the architecture discussion.

Architecture Differences

The two processors come from fundamentally different design points. The Intel Core 5 315 uses the Wildcat Lake codename and is built on a 3 nm process node. The Intel Core i5-14500HX uses the Raptor Lake architecture with a Raptor Lake-HX codename and a 10 nm process node. Both are manufactured by Intel, but the process generation gap is substantial.

Core topology differs sharply. The Core 5 315 provides 6 cores and 6 threads, meaning no simultaneous multithreading. The Core i5-14500HX provides 14 cores and 20 threads, indicating a hybrid configuration with performance and efficiency core classes. The thread count difference is more than threefold in favor of the Core i5.

Cache configurations reflect the different design scales. The Core 5 315 has 192 KB of L1 cache, 2.5 MB of L2, and 6 MB of shared L3. The Core i5-14500HX specifies 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The L3 capacity is four times larger on the Core i5. The Core i5 also has a documented die size of 257 mm², while the Core 5 315 does not list a die size.

Clock behavior differs as well. The Core 5 315 runs a 1.50 GHz base clock with a 4.40 GHz boost clock. The Core i5-14500HX runs a 2.60 GHz base clock with a 4.90 GHz boost clock. The Core i5 holds the advantage in both figures, yet the Core 5 315 wins the PassMark single-thread test, suggesting the newer microarchitecture extracts higher per-clock performance in that specific benchmark.

Power characteristics set these chips far apart. The Core 5 315 has a 15 W TDP, while the Core i5-14500HX has a 55 W TDP. The Core i5 consumes substantially more power, which aligns with its larger core count and higher clock rates. The Core 5 315 targets a much lower power envelope.

Memory support differs. The Core 5 315 supports DDR5 and LPDDR5X with a single-channel memory bus and a recorded bandwidth of 59.7 GB/s. The Core i5-14500HX supports DDR4 and DDR5 with a dual-channel memory bus, though no bandwidth figure is recorded for it. The Core i5 also supports ECC memory, while the Core 5 315 does not.

PCIe connectivity favors the Core i5. The Core 5 315 uses Gen 4 with 6 CPU lanes. The Core i5-14500HX uses Gen 5 with 16 CPU lanes. Integrated graphics also differ: the Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores, while the Core i5-14500HX uses UHD Graphics 770.

Sockets differ. The Core 5 315 uses Intel BGA 1516, while the Core i5-14500HX uses Intel BGA 1964. The multiplier is unlocked on the Core i5-14500HX but locked on the Core 5 315. Release dates show the Core i5 arriving in January 2024 and the Core 5 315 in April 2026.

Where Each One Wins

The Intel Core i5-14500HX wins in every multicore-heavy and throughput-oriented workload in the recorded data. Cinebench R23 multicore shows a 24234 to 12981 advantage, and PassMark multithread shows 28508 to 15272. The integer math result is especially lopsided at 95584 versus 31690, a -66.8% delta, which makes this the strongest single category for the Core i5. Data compression, random string sorting, floating-point math, physics, encryption, and extended instructions all fall in favor of the Core i5 by margins ranging from -34.3% to -56.2%. The Core i5 also wins every Cinebench single-core test despite losing the PassMark single-thread contest. This processor is the clear choice for parallel workloads, compilation, content creation, and any task that can use 20 threads.

The Intel Core 5 315 wins the PassMark single-thread test with 4021 against 3629, a 10.8% margin. This is the only benchmark category where it leads, and it is a meaningful one. The win comes despite a lower boost clock (4.40 GHz versus 4.90 GHz) and a much lower TDP (15 W versus 55 W). The result indicates the Wildcat Lake architecture on the 3 nm node delivers superior per-clock single-thread efficiency in this specific measurement. The Core 5 315 also operates at a far lower power envelope, which makes it suitable for systems where thermal and power constraints are primary considerations. Its single-channel memory bus and 6 MB L3 cache limit its performance ceiling in memory-sensitive workloads, but the PassMark single-thread result shows that for lightly threaded tasks, the newer architecture can overcome the clock disadvantage. The Core 5 315 sits in the 72nd percentile of all CPUs, while the Core i5-14500HX sits in the 84th percentile, confirming the overall performance hierarchy.
