Where Each One Wins
The benchmark data shows a clean sweep for the Intel Core i5-14401E across all six Cinebench tests. The i5-14401E wins every head-to-head comparison, from Cinebench R15 multi-core (1830 vs 1811) to Cinebench R23 single-core (2564 vs 2537). The largest margin comes in Cinebench R15 single-core, where the i5-14401E leads by 1.2%. All other deltas sit at either 1% or 1.1%.
That said, the Xeon E-2378G still has a role. With 8 cores and 16 threads, it offers more parallel execution resources than the 6-core, 12-thread i5-14401E. The Xeon also carries a higher boost clock (5.10 GHz vs 4.70 GHz) and more PCIe lanes (20 vs 16). For workloads that scale with core count beyond what Cinebench captures, the Xeon’s extra two cores could prove useful, even if the benchmark results do not show it winning here.
The i5-14401E’s wins are consistent but narrow. In multi-core tests, it beats the Xeon by exactly 1% in Cinebench R15, R20, and R23. This suggests the i5-14401E’s architectural efficiency offsets the Xeon’s core-count advantage. For single-core workloads, the i5-14401E again leads by 1% to 1.2%. The data indicates the i5-14401E is the stronger performer across the board, but the Xeon is not far behind.
Architecture Differences
The Intel Core i5-14401E uses Raptor Lake architecture (codename Raptor Lake-R) on a 10 nm process. It belongs to the Core 14th Gen family, with a die size of 215 mm². The Intel Xeon E-2378G uses Rocket Lake architecture (codename Rocket Lake-E) on a 14 nm process. It is part of the Xeon E-2300 series, with a larger die size of 276 mm². The process node difference is significant, the i5-14401E’s 10 nm node is denser than the Xeon’s 14 nm node.
Cache configurations differ substantially. The i5-14401E has 1.25 MB of L2 cache per core and 20 MB of shared L3 cache. The Xeon E-2378G has only 512 KB of L2 cache per core and 16 MB of shared L3 cache. Both chips have 80 KB of L1 cache per core. The i5-14401E therefore enjoys a 4 MB L3 advantage and a 2.5x per-core L2 advantage, which helps explain its benchmark edge despite fewer cores.
Memory support also diverges. The i5-14401E supports both DDR4 and DDR5 memory, while the Xeon E-2378G only supports DDR4. The Xeon does list a memory bandwidth figure of 51.2 GB/s, whereas the i5-14401E does not have a listed memory bandwidth in the data. The i5-14401E uses Intel Socket 1700, while the Xeon uses Intel Socket 1200, meaning they are not interchangeable on motherboards.
Integrated graphics differ as well. The i5-14401E includes UHD Graphics 730, while the Xeon E-2378G includes UHD Graphics P750. Both are desktop or workstation class processors, but the i5-14401E is aimed at the desktop market segment, while the Xeon E-2378G targets server and workstation use.
Specification Differences
The core and thread counts are the most obvious difference: 6 cores/12 threads for the i5-14401E versus 8 cores/16 threads for the Xeon E-2378G. The i5-14401E has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The Xeon E-2378G has a base clock of 2.80 GHz and a boost clock of 5.10 GHz. The Xeon runs faster at both ends, with a 0.30 GHz higher base and 0.40 GHz higher boost.
Thermal design power differs, with the i5-14401E rated at 65W and the Xeon at 80W. The Xeon consumes more power but also has more cores and higher clocks. Process node and die size are another key split: 10 nm and 215 mm² for the i5-14401E versus 14 nm and 276 mm² for the Xeon.
Cache layout shows the i5-14401E with 1.25 MB L2 per core and 20 MB L3 shared, versus the Xeon’s 512 KB L2 per core and 16 MB L3 shared. Memory support favors the i5-14401E with DDR4 and DDR5, while the Xeon is limited to DDR4. The Xeon does have a listed memory bandwidth of 51.2 GB/s, while the i5-14401E does not list one.
PCIe capabilities are split: Gen 5 with 16 lanes for the i5-14401E versus Gen 4 with 20 lanes for the Xeon. The i5-14401E has a newer PCIe generation, but the Xeon has more lanes. Both support ECC memory. The i5-14401E has no launch MSRP listed, while the Xeon E-2378G has a launch MSRP of $494. The Xeon was released in September 2021, while the i5-14401E came out in June 2024.
Head-to-Head Benchmarks
All six Cinebench comparisons favor the Intel Core i5-14401E. In Cinebench R15 multi-core, the i5-14401E scores 1830 against the Xeon’s 1811, a 1% lead. Single-core in R15 shows 258 versus 255, a 1.2% margin, the largest win for the i5-14401E in the entire set.
Cinebench R20 multi-core gives the i5-14401E 7627 versus 7549 for the Xeon, again a 1% difference. Single-core in R20 is 1076 against 1065, also 1%. The margins are consistent, suggesting the i5-14401E’s architectural efficiency provides a steady advantage across different Cinebench versions.
Cinebench R23 multi-core shows 18161 for the i5-14401E versus 17974 for the Xeon, a 1% lead. Single-core in R23 is 2564 versus 2537, a 1.1% margin. The i5-14401E wins all six tests, with deltas ranging from 1% to 1.2%. The Xeon E-2378G does not win a single benchmark in this comparison.
The average benchmark scores reflect this. The i5-14401E has an average benchmark score of 5253, while the Xeon E-2378G has 5199. In the nearest rivals list, the i5-14401E sits just ahead of the Intel Core i9-10850K (5240, delta 0.2%) and the Intel Core i5-13400T (5210, delta 0.8%). The Xeon E-2378G sits just behind the Intel Core i5-13400T (5210, delta -0.2%) and trails the i5-14401E by 1%. Both processors land at the 60th percentile among all CPUs, indicating they are closely matched in overall standing.
The Verdict
The data clearly favors the Intel Core i5-14401E. It wins all six head-to-head benchmarks, with margins of 1% to 1.2%. The i5-14401E also has a higher average benchmark score (5253 vs 5199) and a more modern 10 nm process node. Its cache configuration is superior, 1.25 MB L2 per core and 20 MB L3 shared, versus 512 KB L2 per core and 16 MB L3 shared for the Xeon. For users prioritizing raw Cinebench performance, the i5-14401E is the pick.
The Intel Xeon E-2378G is not without merits. It has 8 cores and 16 threads, two more cores than the i5-14401E. It also has a higher boost clock (5.10 GHz vs 4.70 GHz), more PCIe lanes (20 vs 16), and a listed memory bandwidth of 51.2 GB/s. For workloads that can use extra cores beyond what Cinebench captures, the Xeon’s additional resources may matter. Its server/workstation market segment also suggests it targets a different use case than the desktop-oriented i5-14401E.
That said, the benchmark results are unambiguous. The i5-14401E outperforms the Xeon in every measured test, despite having fewer cores and a lower boost clock. The combination of a denser process node, larger caches, and newer architecture gives the i5-14401E the edge. The Xeon’s 8 cores do not translate into Cinebench wins, as the i5-14401E’s efficiency offsets the core-count deficit.
Buyers should choose based on workload. Those running Cinebench-style rendering or single-thread-heavy tasks should take the i5-14401E. Those needing more cores for parallel workloads, or who require the Xeon’s higher boost clock and additional PCIe lanes, may prefer the Xeon E-2378G. The data, however, shows the i5-14401E as the stronger performer in this comparison. The Xeon E-2378G’s launch MSRP is $494, but no price is listed for the i5-14401E. Ultimately, the i5-14401E wins 6-0 in benchmarks, and that is the deciding factor.
