Intel Core 5 320 vs Intel Core i5-14400 Comparison

The Verdict

The benchmark data delivers a clear verdict: the Intel Core i5-14400 is the substantially faster processor in the vast majority of workloads. Across the 17 recorded head-to-head benchmark comparisons, the Core i5-14400 wins 14 tests, while the Intel Core 5 320 wins only 3. The average benchmark score for the Core i5-14400 is 32115, which places it at the 82nd percentile of all CPUs, while the Core 5 320 averages 18023 and sits at the 72nd percentile. The Core i5-14400 is the choice for anyone seeking maximum throughput in multi-threaded tasks, given its 70.9% lead in Cinebench R23 multi-core and its 60.6% advantage in PassMark integer math.

The Intel Core 5 320 does hold two meaningful single-thread wins. It leads in PassMark single-thread scoring by 8.1%, posting 4045 against 3741, and it wins the PassMark find prime numbers test by 37.5%, scoring 110 versus 80. These results indicate that the Core 5 320 has a capable single-core design, but the scope of its victories is narrow. The Core i5-14400 beats it in every Cinebench test, including single-core variants, and dominates the broader workload suite.

The Core 5 320 does have one structural advantage: mobility. It is a mobile-market segment processor with a 15 TDP and an Intel BGA 1516 socket, whereas the Core i5-14400 is a desktop part with a 65 TDP and Intel Socket 1700. The data does not include any power efficiency benchmarks, but the TDP figures alone signal different intended platforms. Anyone building or upgrading a desktop system should select the Core i5-14400 based on its overwhelming benchmark superiority. The Core 5 320 is the only option of the two for a compact mobile platform, and its single-thread PassMark result is the one area where it outclasses the desktop part.

Where Each One Wins

The Intel Core i5-14400 wins across rendering, compression, encryption, and general compute workloads. In Cinebench R15 multi-core, it scores 2148 against 1054, a 50.9% advantage. Cinebench R20 multi-core shows a 39% lead, 8952 versus 5462. The largest margin appears in Cinebench R23 multi-core, where the Core i5-14400 scores 21315 compared to 6197, a 70.9% gap. PassMark integer math favors the Core i5-14400 by 60.6%, with scores of 82017 and 32323. Data compression also belongs to the desktop part: 314995 versus 148779, a 52.8% margin. Random string sorting goes to the Core i5-14400 by 44.2%, 32346 against 18038. Multithread performance, floating point math, extended instructions, data encryption, and physics tests all favor the Core i5-14400 with margins ranging from 12.5% to 38.4%.

The Intel Core 5 320 wins in three tests. The PassMark find prime numbers test shows a 37.5% advantage, 110 versus 80. The PassMark single-thread test, recorded twice with identical results, shows 4045 against 3741, an 8.1% lead. These wins indicate that the Core 5 320 has a competitive single-thread integer execution capability, but the Core i5-14400 still wins every Cinebench single-core test, including a 36% margin in Cinebench R23 single-core. The Core 5 320 therefore wins narrowly in one synthetic single-thread metric and one prime-number workload, while the Core i5-14400 wins decisively in the more comprehensive rendering and compute suites.

Architecture Differences

The two processors come from different Intel design generations and target different platforms. The Intel Core 5 320 uses the Wildcat Lake codename and is built on a 3 nm process node. It has 6 cores and 6 threads, with a base clock of 1.50 GHz and a boost clock of 4.60 GHz. Its cache layout includes 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The processor supports DDR5 and LPDDR5X memory through a single-channel memory bus, delivering 59.7 GB/s of memory bandwidth. It uses Intel Xe3 Graphics with 2 Xe cores as its integrated GPU. The socket is Intel BGA 1516, which is a mobile package. PCIe support is Gen 4 with 6 CPU lanes.

The Intel Core i5-14400 belongs to the Core 14th Gen series, uses the Raptor Lake architecture with the Raptor Lake-R codename, and is manufactured on a 10 nm process node. It has 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Cache resources are larger: 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The die size is 215 mm². Memory support covers DDR4 and DDR5 through a dual-channel memory bus. ECC memory is enabled on this part. The integrated GPU is UHD Graphics 730. The socket is Intel Socket 1700, and PCIe support is Gen 5 with 16 CPU lanes.

The process node difference is substantial: 3 nm versus 10 nm. The Core 5 320 uses fewer, thinner cores but runs on a more advanced node, which likely explains its competitive single-thread PassMark result despite its lower boost clock. The Core i5-14400 compensates with more cores, more threads, higher clocks, and a much larger L3 cache. The memory architecture also differs: single-channel on the Core 5 320 versus dual-channel on the Core i5-14400. The Core i5-14400 also supports ECC memory, while the Core 5 320 does not. PCIe generation and lane counts favor the desktop part as well, with Gen 5 and 16 lanes versus Gen 4 and 6 lanes.
