Architecture Differences
The two processors differ substantially in their internal design. The i5-13420H is built on Raptor Lake (Raptor Lake-H) and uses a 10 nm process, while the Core 5 315 is based on Wildcat Lake and uses a 3 nm process. The i5-13420H has 8 cores and 12 threads, compared to 6 cores and 6 threads for the Core 5 315. Base clocks are 2.10 GHz for the i5-13420H and 1.50 GHz for the Core 5 315; boost clocks are 4.60 GHz and 4.40 GHz respectively. TDP is 45 W for the i5-13420H and 15 W for the Core 5 315. Sockets differ: Intel BGA 1744 for the i5-13420H, Intel BGA 1516 for the Core 5 315. Cache layouts are also different: the i5-13420H has 80 KB L1 per core, 2 MB L2 per core, and 12 MB shared L3; the Core 5 315 has 192 KB L1, 2.5 MB L2, and 6 MB shared L3. Memory support: the i5-13420H supports DDR4 and DDR5 with a dual-channel bus; the Core 5 315 supports DDR5 and LPDDR5X with a single-channel bus, and lists a memory bandwidth of 59.7 GB/s. PCIe: the i5-13420H has Gen 5 with 8 lanes (CPU only), the Core 5 315 has Gen 4 with 6 lanes.

The Core 5 315 has a launch MSRP of $340; the i5-13420H does not have a listed launch MSRP.
Where Each One Wins
The benchmark results indicate that the i5-13420H is stronger in multi-threaded integer workloads. Its 83.5% lead in integer math and 43.3% lead in data compression are the largest margins. It also wins in multithread, random string sorting, and the older Cinebench R15 and R20 versions. This suggests that applications relying on integer arithmetic, compression, and general multi-threaded processing will favor the i5-13420H. The Core 5 315, on the other hand, excels in single-thread PassMark (4021 vs 3396) and in prime number finding (112 vs 52). It also wins in physics and extended instructions, and in the newer Cinebench R23 tests. The Core 5 315's wins in R23 multicore and single-core, despite having fewer cores and threads, point to a more efficient per-core design. The i5-13420H wins in R15 and R20, but the Core 5 315 takes R23, which may reflect the newer architecture's advantage in more recent benchmark versions.
The Verdict
Based strictly on the recorded data, the choice depends on the workload. For tasks that involve integer math, data compression, and multi-threaded processing, the Intel Core i5-13420H is the better option, with substantial leads in those areas. For single-thread performance as measured by PassMark, and for prime number finding, the Intel Core 5 315 is ahead. The Core 5 315 also wins in Cinebench R23, which is a more recent benchmark. The i5-13420H has a higher TDP (45 W vs 15 W) and more cores, while the Core 5 315 uses a newer 3 nm process and has a launch MSRP of $340. Users who prioritize multi-threaded integer workloads should select the i5-13420H; those who need the single-thread edge and newer benchmark performance should consider the Core 5 315.
