Architecture Differences

The two processors come from fundamentally different Intel designs. The Intel Core 5 315 uses the Wildcat Lake codename and is built on a 3 nm process node, while the Intel Core i5-14400T uses the Raptor Lake-R codename and is built on a 10 nm process node. The die size also differs: the i5-14400T measures 215 mm², while the Core 5 315 has no recorded die size in the database.

Cache architecture shows major differences. The Core 5 315 has a total L1 cache of 192 KB, L2 of 2.5 MB, and L3 of 6 MB shared. The i5-14400T lists L1 as 80 KB per core, L2 as 1.25 MB per core, and L3 as 20 MB shared. The i5-14400T's L3 cache is more than three times larger in total capacity, which contributes to its advantage in data-heavy workloads.

Memory support also diverges. The Core 5 315 supports DDR5 and LPDDR5X memory with a single-channel bus and a recorded memory bandwidth of 59.7 GB/s. The i5-14400T supports DDR4 and DDR5 with a dual-channel bus, and its memory bandwidth is not recorded in the database. The i5-14400T supports ECC memory, while the Core 5 315 does not.

PCIe capabilities differ sharply. The Core 5 315 provides Gen 4 with 6 lanes (CPU only), while the i5-14400T provides Gen 5 with 16 lanes (CPU only). Integrated graphics also differ: the Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores, while the i5-14400T uses UHD Graphics 730.

The market segments are distinct. The Core 5 315 is a mobile processor with a 15 W TDP and an Intel BGA 1516 socket. The i5-14400T is a desktop processor with a 35 W TDP and an Intel Socket 1700. The release dates are separated by over two years: the Core 5 315 was released on 2026-04-15, while the i5-14400T was released on 2024-01-07.

The Verdict

The recorded data shows that the Intel Core i5-14400T is the stronger processor in the vast majority of workloads. It wins 14 of 17 head-to-head benchmarks, with consistent 24.5% leads across all Cinebench multi-core and single-core tests. Its average benchmark score of 27166 is substantially higher than the Core 5 315's 18188, and its 79th percentile ranking beats the Core 5 315's 72nd percentile.

The Intel Core 5 315, however, is not without merit. It wins PassMark single-thread by 14.5% and PassMark find prime numbers by 53.4%. For workloads that rely on single-threaded integer iteration or prime-number sieving, the Core 5 315 is the better choice. Its 3 nm process node and lower 15 W TDP also position it as a more power-efficient mobile part, suitable for thin-and-light systems where thermal headroom is limited.

For desktop users who need raw multi-threaded performance, data compression, integer math, or encryption throughput, the i5-14400T is clearly superior. Its 10 cores and 16 threads, combined with 20 MB of L3 cache and dual-channel memory support, drive the large margins seen in the benchmarks. The i5-14400T also offers ECC memory support and PCIe Gen 5 connectivity, features absent from the Core 5 315.

The Core 5 315's single-channel memory bus and lack of ECC support are notable limitations. Its 6 MB L3 cache is a fraction of the i5-14400T's 20 MB, which explains some of the gap in data-heavy tasks. The mobile socket and 15 W TDP make it unsuitable for desktop builds, while the i5-14400T's Socket 1700 is a standard desktop platform.

Where Each One Wins

The Intel Core i5-14400T wins in all multi-threaded rendering tasks. Cinebench R15, R20, and R23 multi-core tests all show a 24.5% advantage. It also wins PassMark multithread by 24.5%, PassMark integer math by 51.7%, PassMark data compression by 38%, PassMark random string sorting by 30.3%, PassMark data encryption by 16%, PassMark extended instructions by 9.7%, PassMark floating-point math by 13.6%, and PassMark physics by 6.5%. In single-core Cinebench tests, the i5-14400T also leads by 24.5% across R15, R20, and R23.

The Intel Core 5 315 wins in PassMark find prime numbers with a 53.4% margin, and in PassMark single-thread with a 14.5% margin. These two wins point to a specific strength: workloads that involve prime-number sieving or lightweight single-threaded operations. The Core 5 315's 3 nm process node and higher single-thread PassMark score suggest it handles simple integer loops efficiently, even with fewer cores.

For overall average benchmark score, the i5-14400T leads with 27166 versus 18188. The nearest rival data confirms the class difference: the i5-14400T sits near the Intel Core i9-9900K (27097, 0.3% lower) and AMD Ryzen 7 5700G (27051, 0.4% lower), while the Core 5 315 sits near the AMD EPYC 9274F (18189, 0% delta) and Intel Core i7-9700 (18180, 0% delta).

In practical terms, the i5-14400T is the processor for desktop workloads that scale with cores and threads. The Core 5 315 is the processor for mobile devices where power draw is constrained, and where single-thread PassMark performance matters more than multi-thread throughput. The data does not support using the Core 5 315 for heavy rendering, compression, or encryption tasks; the i5-14400T dominates those areas by margins ranging from 6.5% to 51.7%.
