Intel Core 5 315 vs Intel Core i9-14901KE Comparison

The Verdict

The Intel Core 5 315 and Intel Core i9-14901KE target entirely different system classes. The Core 5 315 is a mobile processor, built for thin and light laptops with a 15 W TDP. The Core i9-14901KE is a desktop processor, designed for full-size systems with a 125 W TDP. The benchmark database places the Core 5 315 in the 72nd percentile of all CPUs, while the Core i9-14901KE sits at the 50th percentile. However, the Core i9-14901KE has no recorded benchmark scores in the database, meaning the Core 5 315 has a complete set of performance measurements and the Core i9-14901KE has none.

The Core 5 315 shows an average benchmark score of 18188. Its nearest rivals include the AMD EPYC 9274F at 18189 (0% delta), the Intel Core i7-9700 at 18180 (0% delta), the Intel Core i7-1365U at 18177 (0.1% delta), and the AMD Ryzen 7 5700U at 18176 (0.1% delta). These comparisons show the Core 5 315 performing essentially at parity with a server-class EPYC part and a last-generation desktop Core i7 in the database's aggregate scoring. The Core i9-14901KE cannot be compared this way because the database has no benchmark entries for it.

The Core 5 315 is the only one of the two with a launch MSRP, listed at $340. The Core i9-14901KE has no launch MSRP recorded. Neither part should be selected based on price data from the database, since only one has such a field.

For a mobile system where battery life and low heat output matter, the Core 5 315 is the clear choice based on its 15 W TDP and mobile market segment. For a desktop system where raw core count and thread count matter, the Core i9-14901KE has the structural advantage with 8 cores and 16 threads versus 6 cores and 6 threads. But without benchmark data for the Core i9-14901KE, its actual performance cannot be verified in the database.

Architecture Differences

The two processors come from different Intel design families. The Core 5 315 uses the Wildcat Lake codename, built on a 3 nm process node. The Core i9-14901KE uses the Raptor Lake-R codename with the Raptor Lake architecture, built on a 10 nm process node. The Core 5 315 belongs to the Core 5 (Wildcat Lake) generation, while the Core i9-14901KE belongs to the Core 14th Gen series and the Core i9 (Raptor Lake Refresh) generation.

The Core 5 315 has 6 cores and 6 threads, meaning it does not use simultaneous multithreading. The Core i9-14901KE has 8 cores and 16 threads, meaning each core supports two threads. This is a fundamental difference in how many concurrent workloads each can handle.

Cache layouts differ substantially. The Core 5 315 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core i9-14901KE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core i9-14901KE's L3 cache is six times larger, which helps with workloads that repeatedly access large datasets.

The Core 5 315 uses a single-channel memory bus with DDR5 and LPDDR5X support, delivering 59.7 GB/s of memory bandwidth. The Core i9-14901KE uses a dual-channel memory bus with DDR4 and DDR5 support. The Core i9-14901KE supports ECC memory, while the Core 5 315 does not.

The integrated graphics differ as well. The Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores. The Core i9-14901KE uses UHD Graphics 770. The Core 5 315 supports PCIe Gen 4 with 6 CPU lanes, while the Core i9-14901KE supports PCIe Gen 5 with 16 CPU lanes. The Core 5 315 has an unlocked multiplier set to false, while the Core i9-14901KE has an unlocked multiplier.

The socket types are completely different. The Core 5 315 uses Intel BGA 1516, a ball-grid array soldered to the motherboard, typical for mobile parts. The Core i9-14901KE uses Intel Socket 1700, a desktop socket with a removable processor. The Core 5 315 has a die size not recorded, while the Core i9-14901KE has a die size of 257 mm².

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for these two processors. The headToHeadBenchmarks array is empty, and the winsA and winsB counters are both zero. This means there are no direct comparison scores to walk through.

The Core 5 315 does have a complete benchmark suite. In Cinebench R15, it scores 1308 in multicore and 184 in single-core. In Cinebench R20, it scores 5452 in multicore and 769 in single-core. In Cinebench R23, it scores 12981 in multicore and 1832 in single-core. PassMark results include 146143 in data compression, 11119 in data encryption, 13143 in extended instructions, 112 in find prime numbers, 42441 in floating point math, 31690 in integer math, 15272 in multithread, 1163 in physics, 17551 in random string sorting, and 4021 in single-thread.

The Core i9-14901KE has no benchmark entries in the database. Its avgBenchmarkScore is 0, and its percentileVsAllCpus is 50. Without recorded measurements, no comparison of their actual performance can be made from this data.

The nearest rival data for the Core 5 315 provides context for its aggregate performance. It matches the AMD EPYC 9274F within 0% and the Intel Core i7-9700 within 0%. It is 0.1% ahead of the Intel Core i7-1365U and 0.1% ahead of the AMD Ryzen 7 5700U. These delta values are all effectively zero, meaning the Core 5 315 delivers average benchmark scores nearly identical to those four processors.
