Intel Xeon E-2186M vs Intel Xeon E-2324G Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two Xeon processors. The Intel Xeon E-2186M wins seven of the eight recorded head-to-head comparisons, while the Intel Xeon E-2324G claims a single, decisive victory in Geekbench single-core testing.

Starting with multi-threaded workloads, the E-2186M maintains a consistent advantage across all three Cinebench versions. In Cinebench R15 multi-core, the E-2186M scores 961 against 886 for the E-2324G, a margin of 8.5%. That same 8.5% delta repeats in Cinebench R20 multi-core, where the E-2186M posts 4007 versus 3694. Cinebench R23 multi-core follows the identical pattern: 9542 for the E-2186M and 8797 for the E-2324G, again an 8.5% gap. The consistency of this margin across three different Cinebench generations suggests the advantage is structural, not workload-specific.

Single-core Cinebench results also favor the E-2186M, though by slightly less uniform margins. Cinebench R15 single-core shows 135 versus 125, an 8% difference. Cinebench R20 single-core records 565 versus 521, an 8.4% gap. Cinebench R23 single-core follows at 1347 versus 1242, matching the 8.5% delta seen in multi-core tests. These results are notable because the E-2324G has a higher base clock of 3.10 GHz compared to 2.90 GHz for the E-2186M, yet it still trails in single-threaded Cinebench workloads.

Geekbench tells a different story. In Geekbench multi-core, the E-2186M edges out the E-2324G by only 0.9%, scoring 5306 against 5257. This is a much narrower margin than the Cinebench results suggest, indicating that the E-2324G's architecture is more competitive in certain multi-threaded scenarios. The real outlier is Geekbench single-core, where the E-2324G dominates with a score of 2059 against 1434 for the E-2186M. That is a 30.4% advantage, the largest delta in either direction across all recorded benchmarks.

The average benchmark score in the database places the E-2186M at 2912 and the E-2324G at 2823. Both processors sit at the 51st percentile among all CPUs tracked in the database, meaning they occupy essentially the same tier of overall performance despite their divergent benchmark profiles. The E-2186M's nearest rivals include the AMD Ryzen 5 PRO 1600 at 2909 (0.1% delta) and the Intel Core i5-1335UE at 2907 (0.2% delta), while the E-2324G sits near the AMD Ryzen 3 PRO 5450U at 2829 (-0.2% delta) and the Intel Core i5-10600 at 2837 (-0.5% delta).

The Verdict

The data points toward the Intel Xeon E-2186M as the better overall processor for sustained multi-threaded workloads. It wins all three Cinebench multi-core tests by 8.5%, wins all three Cinebench single-core tests by roughly 8% to 8.5%, and takes Geekbench multi-core by a narrow 0.9%. Its average benchmark score of 2912 exceeds the E-2324G's 2823 by about 3.2%. For anyone running Cinebench-class rendering workloads, the choice is straightforward: the E-2186M delivers consistently higher scores across the board.

The Intel Xeon E-2324G, however, has one compelling argument in its favor. Its Geekbench single-core score of 2059 crushes the E-2186M's 1434, a 30.4% advantage that dwarfs any other difference between these two chips. Applications that are heavily dependent on single-threaded Geekbench-style performance would see a substantial benefit from the E-2324G. The E-2324G also posts a higher Geekbench multi-core score relative to its Cinebench performance, suggesting its architecture handles certain mixed workloads better than the raw Cinebench numbers imply.

Both processors share the same 51st percentile ranking in the database, so neither represents a dramatic step up in overall performance tier. The selection comes down to workload character. The E-2186M is the safer all-around choice with seven wins out of eight head-to-head comparisons. The E-2324G is the specialist pick for single-threaded Geekbench-sensitive tasks, where its 30.4% lead is impossible to ignore.

Architecture Differences

The two processors come from different generations and microarchitectures. The Intel Xeon E-2186M belongs to the Xeon E-2100 series and uses the Coffee Lake architecture, specifically the Coffee Lake-H codename. The Intel Xeon E-2324G belongs to the Xeon E-2300 series and uses the Rocket Lake architecture, with the Rocket Lake-E codename. The generation field in the database labels them as Xeon E (Coffee Lake) and Xeon E (Rocket Lake-E) respectively.

Both chips are built on Intel's 14 nm process node, but their die sizes differ substantially. The E-2186M has a die size of 154 mm², while the E-2324G measures 276 mm². The larger die on the E-2324G accommodates a different core layout despite having fewer cores.

Core and thread counts diverge significantly. The E-2186M offers 6 cores and 12 threads, while the E-2324G has 4 cores and 4 threads. The E-2186M's Hyper-Threading support doubles its thread count, whereas the E-2324G runs one thread per core. This explains the E-2186M's consistent multi-core advantage in Cinebench tests, despite the E-2324G's newer architecture.

Cache hierarchies also differ. The E-2186M has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 12 MB of shared L3 cache. The E-2324G has a larger per-core L1 at 80 KB and a larger per-core L2 at 512 KB, but its shared L3 cache is only 8 MB. The E-2186M's larger L3 pool likely contributes to its better scaling in multi-threaded Cinebench workloads.

Clock speeds favor the E-2324G at the base level. The E-2324G runs at 3.10 GHz base and 4.60 GHz boost, while the E-2186M runs at 2.90 GHz base and 4.80 GHz boost. The E-2186M has the higher boost ceiling, which helps explain its single-core Cinebench wins, while the E-2324G's higher base clock does not translate into Cinebench single-core superiority.

Memory and I/O capabilities differ as well. Both support DDR4 memory with dual-channel buses, but the E-2186M has a memory bandwidth of 42.7 GB/s while the E-2324G reaches 51.2 GB/s. The E-2186M uses PCIe Gen 3 with 16 lanes from the CPU, while the E-2324G uses PCIe Gen 4 with 20 lanes. Both support ECC memory. Integrated graphics differ: the E-2186M carries UHD Graphics P630, while the E-2324G carries UHD Graphics P750.

The sockets are incompatible. The E-2186M uses Intel BGA 1440, a mobile-style socket, while the E-2324G uses Intel Socket 1200. The E-2186M has a 45 W TDP, while the E-2324G has a 65 W TDP. Production status also differs, with the E-2186M marked as end-of-life and the E-2324G marked as active.

Where Each One Wins

The Intel Xeon E-2186M wins in every Cinebench scenario. It leads by 8.5% in Cinebench R15 multi-core (961 versus 886), by 8.5% in Cinebench R20 multi-core (4007 versus 3694), and by 8.5% in Cinebench R23 multi-core (9542 versus 8797). It also wins all three Cinebench single-core tests by roughly 8% to 8.5%. In Geekbench multi-core, it wins narrowly by 0.9% (5306 versus 5257). For rendering workloads, video encoding, batch processing, and any task that scales with thread count, the E-2186M is the clear pick. Its 12 threads versus 4 threads and its larger 12 MB shared L3 cache versus 8 MB give it structural advantages that show up consistently across all Cinebench versions.

The Intel Xeon E-2324G wins only Geekbench single-core, but it wins that test by a landslide. Its 2059 score against 1434 represents a 30.4% advantage, by far the largest delta in the entire comparison. This suggests the Rocket Lake architecture delivers substantially stronger single-threaded performance in Geekbench's specific workload mix, despite the E-2186M's higher boost clock of 4.80 GHz versus 4.60 GHz. Applications that are single-thread-bound and resemble Geekbench's test patterns would favor the E-2324G. The E-2324G also has a higher memory bandwidth at 51.2 GB/s versus 42.7 GB/s, which could benefit memory-intensive single-threaded tasks. Its PCIe Gen 4 support with 20 lanes versus Gen 3 with 16 lanes provides a more modern I/O platform, though the benchmark data does not capture I/O performance directly.

For users running a mix of workloads, the E-2186M is the more balanced choice, as it wins seven of eight benchmarks and has a higher average score of 2912 versus 2823. The E-2324G is the specialist option for scenarios where Geekbench single-core performance is the primary metric.
