CPU Comparison

The Intel Xeon E-2414 is the outright winner in every benchmark comparison against the Intel Xeon E-2186M, despite having fewer cores and threads. Across all six head-to-head tests, the E-2414 consistently outperforms its older counterpart by approximately 5%, establishing a clear performance hierarchy that favors the newer Raptor Lake architecture.

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Xeon E-2414 wins all six head-to-head comparisons. In Cinebench R15 multicore, the E-2414 scores 1012 against the E-2186M's 961, a 5% advantage. The single-core R15 test shows a similar pattern, with the E-2414 at 142 versus 135 for the E-2186M, a 4.9% lead.

Moving to Cinebench R20, the E-2414 maintains its edge with a multicore score of 4219 compared to 4007 for the E-2186M, again a 5% difference. The single-core R20 result follows suit: 595 for the E-2414 versus 565 for the E-2186M, another 5% gap. The consistency of these margins is striking, every deltaPct in the head-to-head results lands at either -5 or -4.9, indicating a uniform performance advantage across workloads.

Cinebench R23 reinforces this pattern. The E-2414 posts a multicore score of 10046, while the E-2186M manages 9542, a 5% difference. In single-core R23, the E-2414 achieves 1418 against 1347 for the E-2186M, yet another 5% margin. Notably, the E-2414 accomplishes these wins with only 4 cores and 4 threads, while the E-2186M has 6 cores and 12 threads. This suggests the architectural efficiency of Raptor Lake compensates for the core-count deficit.

The average benchmark scores tell a similar story. The E-2186M averages 2912 across its benchmark suite, while the E-2414 averages 2905, a negligible 0.2% difference that places them as near-identical overall performers. Both CPUs sit at the 51st percentile of all CPUs, with the E-2186M's nearest rival being the AMD Ryzen 5 PRO 1600 at 2909 (0.1% delta), and the E-2414's nearest rival being the Intel Core i5-1335UE at 2907 (-0.1% delta). The two Xeons are essentially tied in aggregate performance, but the E-2414 wins every individual test.

Architecture Differences

The architectural divide between these two processors is substantial. The E-2186M belongs to the Xeon E-2100 series, built on Coffee Lake using a 14 nm process node from Intel. Its codename is Coffee Lake-H, and it uses the Intel BGA 1440 socket. The die size measures 154 mm². In contrast, the E-2414 is part of the Xeon E-2400 series, based on Raptor Lake with a 10 nm process node and the Raptor Lake-S codename. It uses the Intel Socket 1700 and has a slightly larger die at 163 mm².

Cache configurations differ markedly. The E-2186M features 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 12 MB of shared L3 cache. The E-2414 offers 80 KB of L1 per core and a substantially larger 1.25 MB of L2 per core, also with 12 MB of shared L3. The larger per-core L2 cache in the E-2414 likely contributes to its single-core performance advantage despite the lower clock speeds.

Memory support represents a generational leap. The E-2186M supports DDR4 with dual-channel memory and a bandwidth of 42.7 GB/s. The E-2414 supports DDR5, also dual-channel, but with significantly higher bandwidth at 76.8 GB/s. Both support ECC memory. PCIe capabilities also differ: the E-2186M offers Gen 3 with 16 lanes, while the E-2414 provides Gen 5 with 16 lanes.

Clock speeds favor the older chip on paper. The E-2186M has a base clock of 2.90 GHz and a boost clock of 4.80 GHz, while the E-2414 runs at 2.60 GHz base and 4.50 GHz boost. The E-2186M also has a lower TDP of 45 watts versus 55 watts for the E-2414. The E-2186M includes integrated UHD Graphics P630, while the E-2414 has no integrated graphics. The E-2186M was released on 2018-04-03 and is end-of-life, while the E-2414 launched on 2023-12-13 and remains active.

Where Each One Wins

The E-2414 wins everywhere in the benchmark data, but the nature of its victories varies by workload type. In single-core tests, the E-2414's advantage stems from architectural efficiency rather than clock speed, since the E-2186M has higher base and boost clocks. The 4.9-5% single-core margins across R15, R20, and R23 suggest the Raptor Lake core design delivers more instructions per clock.

For multicore workloads, the E-2414's win is more surprising given its 4-core/4-thread configuration versus the E-2186M's 6-core/12-thread setup. The consistent 5% multicore advantage indicates that the E-2414's per-core efficiency and superior memory bandwidth (76.8 GB/s versus 42.7 GB/s) more than compensate for having two fewer physical cores and eight fewer threads.

The E-2186M's theoretical advantages, higher clocks, more cores, more threads, lower TDP, do not translate into benchmark wins. Its integrated graphics provide a feature the E-2414 lacks, but this does not appear in the benchmark scores. The E-2186M's 45-watt TDP makes it more power-efficient on paper, but the E-2414's 55-watt TDP is still modest for a server/workstation part.

The Verdict

The data points decisively to the Intel Xeon E-2414 for any workload measured in these benchmarks. It wins all six head-to-head tests with a consistent 5% margin, achieving this with fewer cores and threads than the E-2186M. The architectural advantages of Raptor Lake, larger per-core caches, DDR5 support, and higher memory bandwidth, overcome the E-2186M's higher clock speeds and core count.

The E-2414 is the appropriate choice for users prioritizing raw Cinebench performance, particularly in single-threaded applications where its efficiency shines. Its active production status and newer release date (2023-12-13 versus 2018-04-03) also make it the more future-proof option. The E-2186M's integrated graphics and lower TDP remain its only distinguishing features, but neither appears in the benchmark results.

For workloads that benefit from more threads, the E-2186M's 6-core/12-thread configuration might seem appealing, but the benchmark data shows the E-2414 still wins multicore tests. The E-2186M's 45-watt TDP versus 55-watt TDP for the E-2414 is the only metric where the older chip leads, and this does not translate to performance advantages. Both CPUs sit at the 51st percentile of all CPUs, but the E-2414 achieves this with a smaller, more efficient core design. The verdict is straightforward: the E-2414 is the better performer in every measured category.
