Intel Xeon E-2126G vs Intel Xeon E-2414 Comparison

The Intel Xeon E-2414 and the Intel Xeon E-2126G represent two distinct eras of Intel’s workstation silicon. The data shows a clear generational shift, with the newer Raptor Lake-based part consistently outperforming the older Coffee Lake design across every recorded benchmark. While both processors target the same server and workstation segment and share a 51st percentile ranking among all CPUs, their performance trajectories and platform requirements diverge significantly. The E-2414, with its higher boost clock and newer architecture, posts decisive wins in both single-threaded and multi-threaded workloads, despite having fewer physical cores than its predecessor.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the Intel Xeon E-2414 wins all six recorded comparisons. The margins are remarkably consistent, hovering around 13% in the majority of tests. In Cinebench R23 multi-core, the E-2414 scores 10,046 points against the E-2126G’s 8,891, a 13% advantage. This is notable because the E-2126G has six cores to the E-2414’s four, meaning the newer chip is delivering higher throughput with two fewer processing units, a signal of its architectural efficiency and superior per-core performance.

The single-core results tell a similar story. In Cinebench R23 single-core, the E-2414 scores 1,418 versus 1,255 for the E-2126G, again a 13% difference. This gap is consistent across all Cinebench versions. In the R20 suite, the E-2414 posts 4,219 multi-core and 595 single-core scores, while the E-2126G manages 3,734 and 527 respectively, yielding 13% and 12.9% deltas. The R15 tests show the same pattern: 1,012 versus 896 multi-core (12.9%) and 142 versus 126 single-core (12.7%). There is no benchmark category where the older Xeon manages to close the gap or take a lead; the younger part’s wins are uniform and decisive.

It is worth contextualizing these scores against the broader market. The E-2414’s average benchmark score of 2,905 places it within 0.1% of the Intel Core i5-1335UE and the AMD Ryzen 5 PRO 1600, and 0.2% behind the Intel Xeon E-2186M. The E-2126G, with an average score of 2,842, sits within 0.1% of the Intel Core i7-6800K and 0.2% of the Intel Core i5-10600. Both chips occupy the same competitive tier, but the E-2414 does so with a clear internal advantage over its direct predecessor. The recorded data shows that the E-2414’s six benchmark wins come with an average delta of roughly 12.9%, a substantial margin for two processors in the same product family.

FAQ

Q: Which processor has the higher boost clock?

A: Both the Intel Xeon E-2414 and the Intel Xeon E-2126G share the same maximum boost clock of 4.50 GHz. The difference lies in their base clocks: the E-2414 runs at 2.60 GHz, while the E-2126G runs at 3.30 GHz.

Q: How do their multi-core performances compare in Cinebench R23?

A: The Intel Xeon E-2414 scores 10,046 points, which is 13% higher than the E-2126G’s 8,891 points. This is despite the E-2126G having six cores to the E-2414’s four.

Q: Is the older Xeon E-2126G still in production?

A: No. The database lists the Intel Xeon E-2126G as end-of-life, while the Intel Xeon E-2414 is listed as active production. The E-2126G was released in 2018, and the E-2414 was released in 2023.

Q: Do both processors support ECC memory?

A: Yes. Both the Intel Xeon E-2414 and the Intel Xeon E-2126G support error-correcting code (ECC) memory, which is a key feature for workstation and server reliability.

Q: Which processor has a higher average benchmark score?

A: The Intel Xeon E-2414 has an average benchmark score of 2,905, which is higher than the E-2126G’s 2,842. Both processors hold the same 51st percentile ranking among all CPUs.

Q: What is the difference in memory bandwidth?

A: The E-2414 supports DDR5 memory with a bandwidth of 76.8 GB/s, while the E-2126G supports DDR4 with a bandwidth of 42.7 GB/s. The newer chip offers substantially higher memory throughput, which can benefit memory-intensive workloads.

Architecture Differences

The two processors are built on fundamentally different platforms. The Intel Xeon E-2414 uses the Raptor Lake architecture, specifically the Raptor Lake-S die, fabricated on a 10 nm process node by Intel. The die size is 163 mm². In contrast, the Intel Xeon E-2126G uses the Coffee Lake architecture, specifically the Coffee Lake-S WS die, fabricated on a 14 nm process node, also by Intel, with a die size of 154 mm². The shift from 14 nm to 10 nm is a primary driver of the performance and efficiency gains observed in the benchmarks.

Core configurations differ as well. The E-2414 has 4 cores and 4 threads, while the E-2126G has 6 cores and 6 threads. Neither processor supports hyper-threading, so thread counts match core counts. Cache hierarchies also show generational changes. The E-2414 has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, while the E-2126G has 64 KB of L1 per core and 256 KB of L2 per core. Both share a 12 MB L3 cache. The larger L2 cache on the newer chip likely contributes to its superior single-threaded performance.

Platform support is another significant divergence. The E-2414 uses Intel Socket 1700 and supports DDR5 memory in a dual-channel configuration, achieving 76.8 GB/s of memory bandwidth. It also features PCIe Gen 5 with 16 lanes (CPU only). The E-2126G uses Intel Socket 1151, supports DDR4 in dual-channel mode with 42.7 GB/s bandwidth, and is limited to PCIe Gen 3 with 16 lanes. The E-2414 also has no integrated graphics, while the E-2126G includes Intel HD Graphics P630. This makes the newer chip reliant on a discrete GPU, whereas the older model can output video without an add-in card.

The E-2414’s power profile is more efficient on paper: it has a TDP of 55 watts versus 80 watts for the E-2126G, despite delivering higher performance in every measured test. The production status also differs, with the E-2414 listed as active and the E-2126G as end-of-life. The E-2414 carries a launch MSRP of $225, and the E-2126G carried a launch MSRP of $255.

The Verdict

Based strictly on the recorded data, the Intel Xeon E-2414 is the superior processor in raw performance. It wins every benchmark in the comparison, posting roughly 13% higher scores in both single-core and multi-core Cinebench tests. This is a decisive result, especially considering the E-2414 achieves it with fewer cores (4 versus 6) and a lower TDP (55 watts versus 80 watts). For workloads that are sensitive to single-threaded speed, such as legacy software or lightly threaded applications, the E-2414’s 13% advantage in Cinebench R23 single-core (1,418 versus 1,255) makes it the clear choice.

For multi-threaded tasks, the result is counterintuitive but equally clear. Despite having two fewer cores, the E-2414 still outperforms the E-2126G by 13% in Cinebench R23 multi-core (10,046 versus 8,891). This suggests that the combination of the 10 nm process, larger L2 cache, and higher memory bandwidth more than compensates for the core count deficit. The E-2414 also brings modern platform features: DDR5 support with 76.8 GB/s bandwidth and PCIe Gen 5 connectivity, which are essential for future-proofing a workstation build. The E-2126G’s only advantages are its integrated graphics, which can be useful for basic display output without a dedicated GPU, and its higher base clock of 3.30 GHz, though this does not translate into a performance win.

The E-2126G is an end-of-life product, whereas the E-2414 is active and current. For any new system, the data overwhelmingly favors the E-2414. The older chip may still be relevant for legacy socket 1151 platforms or specific applications that require its integrated graphics, but in pure computational terms, it trails at every measured point. The verdict is straightforward: the Intel Xeon E-2414 is the better performer, the more efficient chip, and the more modern platform. The E-2126G is only preferable if an iGPU is an absolute requirement.
