CPU Comparison

The Intel Xeon E-2378 and Intel Core i5-11500H occupy different corners of the Intel ecosystem, yet their benchmark results place them in close proximity. Both chips carry the same 57th percentile ranking among all CPUs, and their average benchmark scores differ by just 45 points out of roughly 4,200. The Xeon E-2378, a server/workstation part, and the i5-11500H, a mobile processor, are separated by architecture, socket, and market intent, but the data shows a consistent, if narrow, performance edge for the Xeon across every tested workload.

Head-to-Head Benchmarks

The Xeon E-2378 wins all six head-to-head Cinebench comparisons, but the margins are remarkably slim. In Cinebench R15 multi-core, the Xeon scores 1474 against 1427 for the i5-11500H, a 3.3% advantage. The single-core R15 result shows a nearly identical gap: 208 versus 201, a 3.5% lead for the Xeon. These are not the kind of blowout numbers that usually separate a workstation CPU from a mobile part; they are, instead, the signature of two processors performing at a similar level across different thermal and power envelopes.

Moving to Cinebench R20, the pattern holds. The Xeon posts 6145 in multi-core, while the i5-11500H manages 5949, again a 3.3% difference. Single-core R20 scores are 867 for the Xeon and 839 for the mobile chip, another 3.3% margin. The consistency is striking: in R15, R20, and R23, the deltaPct for both single-core and multi-core tests hovers at exactly 3.3% or 3.5%. This uniformity suggests the architectural gap between Rocket Lake-E and Tiger Lake-H translates into a fixed, repeatable performance differential rather than workload-dependent swings.

Cinebench R23 results confirm the trend. The Xeon E-2378 reaches 14633 multi-core, and the i5-11500H follows at 14166, a 3.3% gap. Single-core R23 scores are 2065 and 1999 respectively, again a 3.3% lead for the Xeon. The i5-11500H does not win a single head-to-head benchmark, yet its losses are small enough that in real-world use, the difference might be perceptible only in extended rendering or compile sessions.

The nearest-rival data reinforces this picture. The i5-11500H’s closest competitor is the Intel Core i9-9900, with an average score of 4163; the i5-11500H beats that by 0.6%. Meanwhile, the Xeon E-2378 sits just 1.1% above the i5-11500H in average score, a margin that mirrors the head-to-head results. The Xeon’s other rivals include the Intel Core i5-12500T (0.4% ahead) and the Intel Xeon W-2140B (0.9% behind), placing it in a tightly clustered performance band where a few points separate the entire group.

Q: Which processor has integrated graphics?

A: Only the Intel Core i5-11500H includes integrated graphics, specifically UHD Graphics 750. The Intel Xeon E-2378 has no integrated graphics listed in the data.

Architecture Differences

The two chips come from different Intel process nodes. The Xeon E-2378 uses the 14 nm process and is built on the Rocket Lake-E architecture, part of the Xeon E-2300 series. The i5-11500H, by contrast, uses the 10 nm process and is based on the Tiger Lake-H architecture within the Core 11th Gen family. The die sizes reflect this split: the Xeon measures 276 mm², while the i5-11500H is smaller at 190 mm². Both are manufactured by Intel, but the process and design philosophies diverge significantly.

Cache configurations differ as well. The Xeon E-2378 allocates 512 KB of L2 cache per core and shares 16 MB of L3 cache across all eight cores. The i5-11500H has a larger L2 allocation of 1.25 MB per core but a smaller shared L3 pool of 12 MB. L1 cache is identical at 80 KB per core. The larger per-core L2 on the mobile chip partially compensates for its smaller L3 capacity, which helps explain why the six-core part stays so close to the eight-core Xeon in multi-threaded workloads.

The socket and market segments reinforce their different purposes. The Xeon E-2378 uses Intel Socket 1200 and is classified as a Server/Workstation processor. The i5-11500H uses Intel BGA 1787, a soldered mobile socket, and is classified as a Mobile part. The TDP figures capture this divergence: the Xeon draws 65 watts, while the i5-11500H is rated at 35 watts. The Xeon also comes with a higher base clock of 2.60 GHz and a boost clock of 4.80 GHz, compared to 2.40 GHz base and 4.60 GHz boost for the i5-11500H.

Memory support is similar on the surface, both use dual-channel DDR4 with 51.2 GB/s bandwidth, but ECC support separates them. The Xeon E-2378 includes ECC memory capability, a standard feature for server and workstation parts, while the i5-11500H lacks it entirely. PCIe connectivity is identical at Gen 4 with 20 lanes (CPU only). The Xeon has no integrated graphics, while the i5-11500H ships with UHD Graphics 750. Neither chip has an unlocked multiplier.

The Verdict

The data points to a simple conclusion: the Intel Xeon E-2378 is the faster processor, but only by a narrow margin. In every Cinebench test, from R15 to R23, the Xeon leads by 3.3% to 3.5%. That consistency makes it the safer choice for workloads that rely on sustained multi-threaded performance, such as rendering or server-side processing. Its 8 cores and 16 threads provide a structural advantage over the i5-11500H’s 6 cores and 12 threads, and the ECC memory support adds reliability for workstation tasks where data integrity is paramount.

The Intel Core i5-11500H, despite losing every benchmark, is not a weak performer. Its 35-watt TDP and mobile socket make it suitable for laptops and compact systems where power efficiency matters more than raw throughput. The inclusion of UHD Graphics 750 means it can handle display output without a discrete GPU, which is a practical advantage the Xeon cannot offer. For a user prioritizing portability and integrated graphics, the i5-11500H is the logical pick, even if it trails by 3.3% in compute-heavy tasks.

For a fixed, power-constrained desktop or workstation build, the Xeon E-2378 is the better choice based on benchmark results alone. It wins every head-to-head test, offers ECC memory, and carries a 65-watt TDP that is manageable for a desktop-class cooler. The i5-11500H, meanwhile, is the right option for mobile systems or embedded designs where the BGA socket and lower power draw are non-negotiable. Neither chip is dramatically superior; the Xeon’s edge is real but modest, and the i5-11500H’s feature set makes it competitive in its own segment.
