Intel Core i3-1125G4 vs Intel Xeon E-2144G Comparison

The Intel Xeon E-2144G and the Intel Core i3-1125G4 represent two distinct approaches to quad-core processing, one aimed at workstation stability and the other at mobile efficiency. The recorded data shows a consistent, though often narrow, performance advantage for the Xeon E-2144G across all eight head-to-head benchmark tests, with the largest delta appearing in Geekbench multicore performance. The Core i3-1125G4 does not secure a win in any of the compared metrics, but its underlying architecture reveals a fundamentally different design philosophy that explains its lower power envelope.

Head-to-Head Benchmarks

The benchmark results are uniformly in favor of the Intel Xeon E-2144G, but the margins tell a nuanced story. In the Cinebench R15 multicore test, the Xeon scores 797 against the Core i3's 792, a delta of just 0.6%. The single-core R15 test shows a similar pattern, with the Xeon's 112 edging out the i3's 111 by 0.9%. These differences are within the noise of typical run-to-run variation, indicating that the two processors are effectively matched in raw single-threaded and lightly threaded workloads.

Moving to Cinebench R20, the Xeon E-2144G again takes the lead, scoring 3322 multicore versus 3301 for the i3-1125G4, another 0.6% margin. The single-core R20 result is 468 versus 465, again a 0.6% advantage for the Xeon. This pattern of near-identical scores repeats in Cinebench R23, where the Xeon posts 7910 multicore and 1116 single-core, against the i3's 7860 and 1109, both deltas at 0.6%. The consistency across these three generations of Cinebench suggests that the architectural and clock differences largely cancel out in this specific rendering workload.

The most significant divergence appears in the Geekbench suite. In Geekbench multicore, the Xeon E-2144G scores 4875 compared to the i3-1125G4's 4509, a substantial 8.1% lead. This is the largest performance gap in the entire comparison. The Geekbench single-core test shows a 3.2% advantage for the Xeon, with scores of 1508 and 1461 respectively. The Geekbench results suggest that the Xeon's higher sustained clock speeds and possibly its memory configuration provide a more meaningful advantage in tasks that stress memory bandwidth and integer operations, as opposed to the more homogeneous floating-point loads of Cinebench. The overall average benchmark score for the Xeon is 2514, placing it at the 49th percentile of all CPUs, while the i3-1125G4 averages 2451, sitting at the 48th percentile. The Xeon's nearest rivals in the database include the Intel Xeon E5-2643 v3 with an average score of 2511 (0.1% delta) and the Intel Xeon E-2244G at 2527 (a -0.5% delta). The i3-1125G4's closest competitor is the Intel Core i5-8600 with an average score of 2454, a -0.1% delta, putting it in a similar performance class despite its mobile pedigree.

Architecture Differences

The two processors are built on fundamentally different foundations. The Intel Xeon E-2144G uses the Coffee Lake-S WS architecture on a 14 nm process node, with a die size of 126 mm². It is a server and workstation part designed for the Intel Socket 1151 platform. In contrast, the Intel Core i3-1125G4 is a Tiger Lake-U mobile processor built on a 10 nm process, with a larger die size of 144 mm², and is designed for the Intel BGA 1449 socket. These process and packaging differences directly influence their power profiles and target systems.

Cache hierarchies also differ. The Xeon E-2144G provides 64 KB of L1 cache and 256 KB of L2 cache per core, while the i3-1125G4 offers a larger 80 KB of L1 and a much larger 1.25 MB of L2 per core. Both processors share 8 MB of L3 cache, but the larger per-core L2 on the Tiger Lake part is a notable architectural shift. The Xeon supports ECC memory, a feature absent on the Core i3, which is a critical distinction for workstation reliability. The Xeon also lists a memory bandwidth of 42.7 GB/s with dual-channel DDR4 support, whereas the memory bandwidth for the i3-1125G4 is not specified in the recorded data, though it supports both DDR4 and LPDDR4X.

PCIe capabilities differ as well, with the Xeon E-2144G supporting PCIe Gen 3 with 16 lanes, while the i3-1125G4 supports the newer PCIe Gen 4 with 16 lanes. Integrated graphics also diverge: the Xeon carries HD Graphics P630, while the i3 features Iris Xe-LP Graphics G4. The Xeon's base clock is 3.60 GHz with a boost of 4.50 GHz, while the i3-1125G4 has a base clock of 2000.00 MHz and a boost of 3.70 GHz. The Xeon's 71-watt TDP is dramatically higher than the i3's 15-watt TDP, reflecting the mobile part's focus on battery preservation and thermal efficiency. The release dates are also far apart, with the Xeon launching in July 2018 and the i3 in March 2021, placing them in different product generations despite their similar core counts.

The Verdict

The data strongly indicates that the Intel Xeon E-2144G is the superior choice for users who require maximum processing throughput in a workstation or server environment. It holds a winning record of 8 to 0 in the head-to-head benchmarks, with its most pronounced advantage being the 8.1% lead in Geekbench multicore performance. Its support for ECC memory and a 42.7 GB/s memory bandwidth further solidifies its position as a reliability-focused part for professional workloads. The higher TDP of 71 watts is a trade-off that is acceptable in a system designed for sustained performance.

The Intel Core i3-1125G4, while trailing in every benchmark, is not without merit. Its 15-watt TDP and 10 nm process node make it a compelling option for compact, power-efficient mobile systems where battery life and thermal output are paramount. Its larger L2 cache and support for LPDDR4X memory suggest an architecture optimized for low-latency access in a constrained power envelope. However, the benchmark scores show that it cannot match the Xeon's output, particularly in Geekbench multicore, where the 8.1% gap is significant. For a user prioritizing performance above all else, the Xeon E-2144G is the clear winner. For a user prioritizing portability and efficiency, the i3-1125G4 is the only logical choice, accepting its lower benchmark scores as a necessary compromise.
