Intel Core i5-8300H vs Intel Xeon E-2124G Comparison

Head-to-Head Benchmarks

The benchmark data splits cleanly along test-family lines. The Intel Core i5-8300H takes every Cinebench iteration, while the Intel Xeon E-2124G sweeps Geekbench. The margins are modest in the former and substantial in the latter.

Starting with Cinebench R15 multicore, the i5-8300H scores 629 against 613 for the Xeon E-2124G, a 2.5% advantage. The single-core R15 result is nearly identical in relative terms: 88 versus 86, a 2.3% edge for the mobile chip. Moving to R20, the pattern holds. The i5-8300H posts 2622 multicore and 370 single-core, while the Xeon E-2124G manages 2558 and 361 respectively. That is a 2.4% gap in both metrics. The R23 results repeat the story: 6245 to 6092 multicore (2.4% lead for the i5-8300H) and 881 to 860 single-core (2.4% lead). The consistency of that 2.4% delta across three Cinebench generations suggests a stable performance relationship rather than a workload-specific quirk.

Geekbench flips the script entirely. The Xeon E-2124G scores 4263 multicore versus 3920 for the i5-8300H, an 8.8% win. The single-core Geekbench result is even more decisive: 1438 versus 1286, an 11.8% advantage. That is the largest margin in the entire comparison. The Xeon E-2124G wins two of the eight head-to-head tests, but it wins them by a wider margin than the i5-8300H manages in any of its six victories.

The average benchmark scores place the two chips close together in the database's overall ranking. The Xeon E-2124G sits at 2034, with the i5-8300H at 2005. Both land at the 45th percentile among all CPUs. The Xeon E-2124G's nearest rivals include the AMD Ryzen 5 4500U at 2035 (0% delta) and the Intel Core i7-3960X at 2037 (negative 0.1% delta). The i5-8300H's closest competitor is the Intel Xeon D-1712TR at 2004 (0% delta), followed by the Intel Core i5-8400H at 2003 (0.1% delta). In aggregate, the Xeon E-2124G holds a 1.4% average score advantage, but the Cinebench suite gives the i5-8300H a consistent edge in rendering-style workloads.

The Verdict

The data paints a nuanced picture. If the priority is Cinebench-style rendering performance, the Intel Core i5-8300H is the pick. It wins all six Cinebench comparisons, with multicore leads of 2.4% to 2.5% and single-core leads of 2.3% to 2.4%. The consistency across R15, R20, and R23 indicates that this advantage persists regardless of benchmark version or workload intensity.

If the priority is Geekbench performance, the Intel Xeon E-2124G is clearly ahead. Its 8.8% multicore and 11.8% single-core wins are the largest margins recorded in this comparison. The Xeon E-2124G also carries ECC memory support, which the i5-8300H lacks, and it uses a socketed Intel Socket 1151 platform rather than the soldered Intel BGA 1440 of the mobile chip.

The average benchmark score slightly favors the Xeon E-2124G at 2034 versus 2005, but the percentile ranking is identical at 45. The Xeon E-2124G has an edge in aggregate database standing, yet the i5-8300H's Cinebench dominance means neither chip can be called a universal winner. The choice depends on which benchmark suite reflects the intended workload.

Where Each One Wins

The Intel Core i5-8300H wins in every Cinebench test, which covers both multicore and single-core rendering scenarios. Its multicore advantage likely stems from its 8 threads versus the Xeon E-2124G's 4 threads, though the database records only the final scores, not the specific architectural cause. The single-core Cinebench wins are smaller but consistent, suggesting the i5-8300H's boost behavior in these tests is slightly better despite its lower 3.90 GHz boost clock compared to the Xeon E-2124G's 4.50 GHz.

The Intel Xeon E-2124G wins in Geekbench, both single-core and multicore. The 11.8% single-core margin is particularly notable given that the Xeon E-2124G has a lower base clock of 3.40 GHz versus the i5-8300H's 2.30 GHz, though the Xeon's boost clock is higher at 4.50 GHz versus 3.90 GHz. The Geekbench multicore win of 8.8% is more surprising because the i5-8300H has twice the thread count. The Xeon E-2124G also has ECC memory support, which the i5-8300H does not, a feature relevant for workstation reliability. The Xeon E-2124G's market segment is Server/Workstation, while the i5-8300H targets Mobile, which explains the platform differences.
