Intel Core 5 315 vs Intel Core i5-14401E Comparison

Intel Core 5 315 and Intel Core i5-14401E are two processors aimed at different market segments, one mobile and one desktop. The benchmark data in the database shows a clear performance hierarchy, but the comparison is not straightforward because the two chips serve different physical and power envelopes. The Core 5 315 is a 6-core, 6-thread part built on a 3 nm process with a 15 W TDP, while the Core i5-14401E is a 6-core, 12-thread desktop processor on a 10 nm process with a 65 W TDP. The recorded measurements cover six Cinebench tests, and the Core i5-14401E wins all six.

Head-to-Head Benchmarks

The head-to-head results are consistent across every recorded test. In Cinebench R15 multicore, the Core i5-14401E scores 1830 against 1308 for the Core 5 315, a margin of 28.5% in favor of the desktop chip. The single-core version of R15 shows the same gap: 258 for the Core i5-14401E versus 184 for the Core 5 315, also 28.5% ahead. This pattern repeats in Cinebench R20 multicore, where the scores are 7627 and 5452, and in R20 single-core, where the scores are 1076 and 769. Both show the same 28.5% difference.

Cinebench R23 multicore delivers 18161 for the Core i5-14401E and 12981 for the Core 5 315. The single-core R23 result is 2564 versus 1832. Again, the delta is 28.5% in favor of the Core i5-14401E. The consistency of this margin across all six tests suggests a fundamental performance gap rather than a workload-specific quirk. The Core i5-14401E does not just win by a small amount; it wins by a nearly identical percentage in every benchmark.

The Core 5 315 has no wins in the head-to-head comparison. The database records 0 wins for the Core 5 315 and 6 wins for the Core i5-14401E. This is a dominant result, but it must be read in context. The Core 5 315 is a mobile processor with a 15 W TDP, while the Core i5-14401E is a desktop part with a 65 W TDP. The power envelope difference explains much of the performance gap, and the benchmark scores reflect what each chip is designed to do.

Looking at the average benchmark scores in the database, the Core 5 315 has an average of 18188, while the Core i5-14401E has an average of 5253. This is a large discrepancy, but it is important to note that the averages are computed over different benchmark sets. The Core 5 315 has 17 recorded benchmark scores, including PassMark tests, while the Core i5-14401E has only 6 recorded scores, all Cinebench. The average is not directly comparable across different test suites.

The percentile rankings also differ. The Core 5 315 sits at the 72nd percentile among all CPUs in the database, while the Core i5-14401E sits at the 60th percentile. This is counterintuitive given the head-to-head results, but it reflects the broader benchmark coverage for the Core 5 315. The Core 5 315 has many PassMark scores that pull its average up, and those PassMark tests are not present for the Core i5-14401E.

Where Each One Wins

The Core i5-14401E wins every recorded Cinebench test, and it does so by a consistent margin. This makes it the clear choice for multi-threaded rendering workloads as measured by Cinebench R15, R20, and R23. The 12 threads versus 6 threads is a direct reason. The Core i5-14401E has a higher boost clock (4.70 GHz versus 4.40 GHz) and a higher base clock (2.50 GHz versus 1.50 GHz), which also contributes to its single-core wins. For users running CPU-bound rendering tasks, the data shows the Core i5-14401E delivers about 28.5% more performance across the board.

The Core 5 315 wins in no recorded benchmark. However, the database includes PassMark tests only for the Core 5 315, not for the Core i5-14401E. Those PassMark scores are substantial: data compression at 146143, data encryption at 11119, extended instructions at 13143, floating point math at 42441, integer math at 31690, multithread at 15272, physics at 1163, random string sorting at 17551, and single thread at 4021. Without comparable PassMark data for the Core i5-14401E, it is not possible to declare a winner in those specific workloads. The database only records head-to-head Cinebench results, so the analysis must stay within those six tests.

The Core 5 315 also has a much lower TDP at 15 W, which is a practical advantage in mobile systems. The benchmark data does not measure power consumption, but the TDP figures are recorded. A 15 W processor can be cooled in thin laptops, while a 65 W processor requires a larger cooling solution. The Core 5 315 is designed for the mobile segment, and its performance is competitive within that constraint.

The Core i5-14401E is built on a 10 nm process with the codename Raptor Lake-R and the architecture label Raptor Lake. The 3 nm node is more advanced, which allows the Core 5 315 to achieve its 15 W TDP while still providing competitive performance in its segment.

The cache configurations are notably different. The Core 5 315 has an L1 cache of 192 KB, an L2 cache of 2.5 MB, and an L3 cache of 6 MB shared. The Core i5-14401E has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and an L3 cache of 20 MB shared. The desktop chip has a larger L3 cache by a significant margin, which helps with workloads that benefit from shared cache.

The die size is recorded for the Core i5-14401E at 215 mm², while the Core 5 315 has no die size recorded. The foundry for both is Intel. The Core i5-14401E has a higher thread count because it supports Hyper-Threading, while the Core 5 315 does not. This is a direct architectural difference that shows up in the multi-threaded benchmarks.

The production status for both processors is active. The market segments differ: the Core 5 315 is for mobile, and the Core i5-14401E is for desktop. This is the defining architectural context. The Core 5 315 uses a newer process node, but it is constrained by power and thermal limits. The Core i5-14401E uses an older process node but has the power budget to run at higher clocks and support more threads.

The Verdict

The benchmark data shows that the Intel Core i5-14401E is the faster processor in every recorded Cinebench test. It wins by 28.5% in all six tests, including both single-core and multi-core workloads. The desktop chip has more threads, higher clocks, and a larger L3 cache, all of which contribute to its performance edge. The Core 5 315 cannot match it in raw compute as measured by Cinebench.

However, the two chips are not direct competitors. The Core 5 315 is a mobile processor with a 15 W TDP, and it is built on a 3 nm process. The Core i5-14401E is a desktop processor with a 65 W TDP and a 10 nm process. The mobile chip is designed for battery-powered systems where power efficiency matters more than peak performance. The desktop chip is designed for systems with adequate cooling and power delivery.

The Core 5 315 has a higher percentile ranking (72nd) than the Core i5-14401E (60th), but this is due to the broader benchmark coverage in the database. The Core 5 315 has PassMark scores that are not available for the Core i5-14401E, so the average benchmark score of 18188 for the Core 5 315 is not comparable to the 5253 average for the Core i5-14401E. The head-to-head Cinebench results are the only directly comparable data, and they favor the Core i5-14401E across the board.

For a desktop system where performance is the priority, the Core i5-14401E is the better choice based on the recorded data. It delivers roughly 28.5% more performance in Cinebench R15, R20, and R23, and it supports ECC memory and PCIe Gen 5. For a mobile system where power consumption is critical, the Core 5 315 is the appropriate part, with its 15 W TDP and 3 nm process. The data does not support a claim that the Core 5 315 is faster in any recorded benchmark, but it does show that the mobile chip achieves a substantial performance level within a much lower power envelope. The choice between the two depends on the use case: desktop rendering workloads favor the Core i5-14401E, while mobile computing favors the Core 5 315.
