Intel Xeon E-2244G vs Intel Xeon W-2125 Comparison

Head-to-Head Benchmarks

The recorded data paints a remarkably consistent picture for these two quad-core Xeon processors. Across the majority of benchmark tests, the Intel Xeon W-2125 holds a clear, if modest, advantage over the Intel Xeon E-2244G. The most significant margin appears in Geekbench multi-core testing, where the W-2125 scores 4988 against the E-2244G's 4712, a difference of 5.5 percent. This is the largest multi-core gap recorded between the two parts.

In Cinebench R23 multi-core, the W-2125 posts 8455 points versus 8126 for the E-2244G, a 3.9 percent lead. The single-core variant of the same test shows the W-2125 ahead at 1193 points compared to 1147, again a 3.9 percent difference. The pattern holds in Cinebench R20 as well, with the W-2125 scoring 3551 in multi-core versus 3412 for the E-2244G (3.9 percent), and 501 in single-core versus 481 (4.0 percent). Cinebench R15 results show the W-2125 at 852 multi-core and 120 single-core, against 818 and 115 respectively for the E-2244G, representing 4.0 and 4.2 percent gaps.

There is one notable exception to this trend. In Geekbench single-core testing, the E-2244G turns the tables with a score of 1408, defeating the W-2125's 1323 by a margin of 6.4 percent. This is the largest delta recorded in either direction across the entire benchmark suite. It is also the only test out of eight where the E-2244G emerges victorious.

The overall win tally stands at 7 wins for the W-2125 and 1 win for the E-2244G. The average benchmark score for the W-2125 is 2623, while the E-2244G averages 2527. Both processors sit at the 49th percentile when compared against all CPUs in the database, indicating they occupy a similar tier in overall performance. The W-2125's nearest rivals include the Intel Core i7-1195G7 (average score 2638, 0.6 percent faster), the Intel Core i9-8950HK (2641, 0.7 percent faster), and the Intel Core i7-5820K (2642, 0.7 percent faster). The E-2244G's closest competitor is the Intel Core i3-10325, which scores 2530 on average, a mere 0.1 percent ahead.

The W-2125 also edges out the E-2244G in raw multi-threaded throughput, though the margins are small enough that real-world differences would be difficult to perceive without instrumentation. The Geekbench multi-core result is the most pronounced multi-threaded advantage, while the Cinebench tests consistently show roughly 4 percent differences. In single-threaded workloads outside of Geekbench, the W-2125 maintains a narrow lead, but the Geekbench single-core result flips the narrative entirely, suggesting the E-2244G has a meaningful advantage in certain single-threaded scenarios.

Where Each One Wins

The Intel Xeon W-2125 is the clear winner in rendering and compute-heavy workloads. All three Cinebench versions, R15, R20, and R23, show it ahead in both multi-core and single-core tests. The multi-core margins hover around 3.9 to 4.0 percent, while the single-core margins sit between 3.9 and 4.2 percent. This makes the W-2125 the preferable choice for tasks that rely on sustained CPU compute, such as 3D rendering, video encoding, or scientific simulation. The Geekbench multi-core result reinforces this, with the W-2125 leading by 5.5 percent.

The Intel Xeon E-2244G wins in Geekbench single-core testing, posting a 6.4 percent advantage. This result suggests that for lightly threaded applications, such as legacy software, certain database operations, or interactive workloads where a single thread dominates, the E-2244G may deliver snappier responsiveness. However, this is a single data point. In Cinebench single-core tests, the W-2125 remains ahead, so the Geekbench result should not be overgeneralized.

For users prioritizing multi-threaded throughput, the choice is unambiguous. The W-2125 wins every multi-core test by margins ranging from 3.9 to 5.5 percent. For users who value the Geekbench single-core metric specifically, the E-2244G offers a notable edge, but it loses every other single-core test in the suite. The E-2244G's victory is narrow in context, as it only appears in one benchmark, while the W-2125's dominance spans seven tests.

The average benchmark scores place the W-2125 at 2623 versus 2527 for the E-2244G, a difference of roughly 3.8 percent. This aligns with the individual Cinebench deltas. Both processors are locked multipliers, so overclocking headroom is not a differentiator. The W-2125's higher base clock of 4.00 GHz and boost clock of 4.50 GHz, compared to 3.80 GHz and 4.80 GHz respectively for the E-2244G, explain the mixed results. The W-2125 has a higher base frequency, which helps in sustained workloads, while the E-2244G has a higher boost frequency, which may explain its Geekbench single-core win.

Architecture Differences

The two processors come from different architectural lineages. The E-2244G is built on Coffee Lake, specifically the Coffee Lake-S WS die, and belongs to the Xeon E-2200 series. The W-2125 uses Skylake, specifically the Skylake-W die, part of the Xeon W family. Both use a 14 nm process node from Intel, so transistor-level density is comparable, but the die sizes differ substantially. The E-2244G has a die size of 126 mm², while the W-2125 uses a much larger 484 mm² die. This size difference reflects the W-2125's more extensive uncore and memory infrastructure.

Cache configurations diverge significantly. The E-2244G has 64 KB of L1 cache per core, 256 KB of L2 per core, and 8 MB of shared L3 cache. The W-2125 also has 64 KB of L1 per core, but its L2 cache is 1 MB per core, four times larger. Its L3 cache is 8.25 MB shared, a slight increase over the E-2244G. The larger L2 cache on the W-2125 likely contributes to its multi-core performance advantage, as more data can be held closer to the cores.

Memory support is another major differentiator. Both support DDR4 memory and ECC. However, the E-2244G uses a dual-channel memory bus with a bandwidth of 42.7 GB/s. The W-2125 uses a quad-channel memory bus with a bandwidth of 85.3 GB/s, exactly double. This doubling of memory bandwidth is a critical architectural advantage for the W-2125 in memory-intensive workloads, though the benchmark scores show only modest overall gains, suggesting the tested workloads were not purely bandwidth-bound.

PCIe connectivity also differs. The E-2244G provides Gen 3 with 16 lanes from the CPU. The W-2125 provides Gen 3 with 48 lanes, triple the count. This makes the W-2125 far more suitable for systems with multiple GPUs, high-speed NVMe storage, or other expansion cards. The E-2244G is more limited in expansion capability.

The E-2244G includes integrated graphics in the form of HD Graphics P630. The W-2125 has no integrated graphics, requiring a discrete GPU for display output. This is a notable feature split. The E-2244G uses the Intel Socket 1151, while the W-2125 uses the larger Intel Socket 2066, which is consistent with the W-2125's higher PCIe lane count and quad-channel memory support.

Thermal design power also varies widely. The E-2244G has a TDP of 71 watts, while the W-2125 has a TDP of 120 watts. The W-2125 dissipates significantly more heat, requiring a more robust cooling solution. The E-2244G is more power-efficient on paper, though neither processor is unlocked for multiplier adjustment.

The release dates differ as well. The E-2244G was released on May 28, 2019, while the W-2125 was released earlier on August 28, 2017. Both are end-of-life products. The part numbers are SRFAY for the E-2244G and SR3LM for the W-2125.
