Architecture Differences

The Intel Core 5 315 uses the Wildcat Lake codename and is built on a 3 nm process node, while the Intel Core i7-14650HX belongs to the Raptor Lake architecture, specifically Raptor Lake-HX Refresh, and uses a 10 nm process node. Both are manufactured by Intel, but the process difference is substantial: the Core 5 315 uses a 3 nm node, whereas the i7-14650HX uses a 10 nm node.

The core counts differ sharply. The Core 5 315 provides 6 cores and 6 threads, meaning it has no hyperthreading. The Core i7-14650HX provides 16 cores and 24 threads, which indicates a hybrid configuration with additional efficiency cores plus hyperthreading on the performance cores. The resulting thread advantage is 24 versus 6.

Cache hierarchies also differ. The Core 5 315 has an L1 cache of 192 KB, L2 of 2.5 MB, and 6 MB shared L3. The Core i7-14650HX lists L1 as 80 KB per core, L2 as 2 MB per core, and 30 MB shared L3. The shared L3 difference is large: 30 MB versus 6 MB. The i7-14650HX also has a recorded die size of 257 mm², while the Core 5 315 has no die size recorded.

Memory support differs. The Core 5 315 supports DDR5 and LPDDR5X with a single-channel memory bus and a recorded memory bandwidth of 59.7 GB/s. The Core i7-14650HX supports DDR4 and DDR5 with a dual-channel memory bus; no memory bandwidth figure is recorded for it. ECC memory support is present on the i7-14650HX but absent on the Core 5 315.

PCIe capability differs as well. The Core 5 315 provides Gen 4 with 6 CPU lanes. The Core i7-14650HX provides Gen 5 with 16 CPU lanes. The integrated graphics differ: the Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores, while the i7-14650HX uses UHD Graphics 710.

Clock speeds and power targets also diverge. The Core 5 315 has a base clock of 1.50 GHz, a boost clock of 4.40 GHz, and a TDP of 15 watts. The Core i7-14650HX has a base clock of 2.20 GHz, a boost clock of 5.20 GHz, and a TDP of 55 watts. The multiplier is unlocked on the i7-14650HX, while the Core 5 315 is locked. Sockets differ: Intel BGA 1516 for the Core 5 315 and Intel BGA 1964 for the i7-14650HX.

The release dates place the Core 5 315 as a later product, with a release date in April 2026, while the i7-14650HX was released in January 2024. The Core 5 315 has a recorded launch MSRP of $340.

Where Each One Wins

The Intel Core i7-14650HX dominates multi-threaded and throughput-oriented workloads. In the Cinebench R15 multicore test, it scores 3470.5 against 1308, a 62.3 percent lead. Cinebench R20 multicore shows 11946 versus 5452, a 54.4 percent lead. Cinebench R23 multicore shows 20454 versus 12981, a 36.5 percent lead. PassMark integer math is the largest gap in the dataset: 116661 versus 31690, a 72.8 percent lead. Data compression also favors the i7 heavily, with 398418 versus 146143, a 63.3 percent lead. Data encryption shows 22917 versus 11119, a 51.5 percent lead. Floating-point math shows 84999 versus 42441, a 50.1 percent lead. Random string sorting shows 43035 versus 17551, a 59.2 percent lead. Extended instructions show 24150 versus 13143, a 45.6 percent lead. Physics shows 2202 versus 1163, a 47.2 percent lead. Find prime numbers shows 152 versus 112, a 26.3 percent lead.

The Core 5 315 wins only the single-thread PassMark tests. It scores 4021 versus 3841, a 4.7 percent advantage in both passmark_single_thread and passmark_singlethread. This indicates that despite the i7's higher boost clock of 5.20 GHz versus 4.40 GHz, the Core 5 315 delivers slightly better single-thread throughput in PassMark's measurement. This could be attributed to the newer 3 nm process and the Wildcat Lake architecture, though the recorded data does not directly confirm the cause.

The i7-14650HX also wins the Cinebench R23 single-core test, scoring 1969 versus 1832, a 7 percent lead, and the Cinebench R20 single-core test, scoring 1686 versus 769, a 54.4 percent lead. The Cinebench R15 single-core test shows 285.5 versus 184, a 35.6 percent lead. Therefore, while the Core 5 315 wins in PassMark single-thread, the i7 wins in all three Cinebench single-core tests.

Overall, the i7-14650HX wins 15 of the 17 recorded head-to-head benchmarks. The Core 5 315 wins 2, both being the same PassMark single-thread measurement.

Head-to-Head Benchmarks

The most lopsided result in the comparison is PassMark integer math. The Core i7-14650HX scores 116661 against 31690 for the Core 5 315, a 72.8 percent advantage. This is consistent with the i7 having 16 cores and 24 threads versus 6 cores and 6 threads, though the recorded data does not state the cause directly.

Data compression follows closely. The i7 scores 398418 versus 146143, a 63.3 percent lead. This workload scales well with core count and cache size, and the i7 has both more cores and a larger 30 MB L3 cache. Random string sorting shows a 59.2 percent lead for the i7, with 43035 versus 17551.

The Cinebench R15 multicore test shows a 62.3 percent lead for the i7, with 3470.5 versus 1308. Cinebench R20 multicore shows 11946 versus 5452, a 54.4 percent lead. PassMark multithread shows 33495 versus 15272, also a 54.4 percent lead. Data encryption shows 22917 versus 11119, a 51.5 percent lead. Floating-point math shows 84999 versus 42441, a 50.1 percent lead.

The Cinebench R20 single-core test shows a 54.4 percent lead for the i7, with 1686 versus 769. This is notable because the PassMark single-thread tests favor the Core 5 315. The Cinebench R15 single-core test shows 285.5 versus 184, a 35.6 percent lead for the i7. The Cinebench R23 single-core test shows a narrower 7 percent lead for the i7, with 1969 versus 1832.

Physics results show 2202 versus 1163, a 47.2 percent lead for the i7. Extended instructions show 24150 versus 13143, a 45.6 percent lead. Find prime numbers shows 152 versus 112, a 26.3 percent lead.

The only wins for the Core 5 315 are the two identical PassMark single-thread measurements, where it scores 4021 versus 3841, a 4.7 percent advantage. This is the sole instance in the recorded data where the Core 5 315 outperforms the i7-14650HX. It suggests that the Wildcat Lake core design, despite its lower boost clock, has strong single-thread efficiency in PassMark's specific workload. However, the Cinebench suite does not confirm this trend, as the i7 wins all three Cinebench single-core tests.

The average benchmark scores reflect the overall dominance: 41576 for the i7 versus 18188 for the Core 5 315. The nearest rival data for the Core 5 315 places it near the AMD EPYC 9274F and the Intel Core i7-9700, both with an average score around 18180. The nearest rival data for the i7-14650HX places it near the Intel Core Ultra 7 265H, with an average score of 41621, and the AMD Ryzen 9 5900X, with an average score of 41376. The percentile ranking also differs, with the i7 at 88th percentile versus 72nd for the Core 5 315.
