Intel Core i7-1365UE vs Intel Xeon E5-2628L v3 Comparison

Where Each One Wins

The Intel Xeon E5-2628L v3 wins every recorded benchmark in this comparison. Across all six Cinebench tests, the Xeon holds a consistent edge over the Core i7-1365UE, with deltas ranging from 1.5% to 1.8%. This is a clean sweep in the database, but the margins are narrow enough that the practical distinction lies in deployment context rather than raw capability.

The Xeon E5-2628L v3 is the clear choice for sustained multi-threaded workloads in a server or workstation chassis. Its 10 cores and 20 threads, paired with a quad-channel DDR4 memory bus, give it an edge in heavily parallel tasks such as rendering, batch processing, or virtualized workloads. The data shows a 1.8% lead in Cinebench R15 multicore and a 1.7% lead in both R20 and R23 multicore, which, while small, is consistent across every test.

The Core i7-1365UE, despite having the same core count (10), only offers 12 threads due to its hybrid architecture of performance and efficiency cores. Its strength lies in mobile efficiency, with a 15 W TDP compared to the Xeon's 75 W. In single-threaded tests, the i7 comes within 1.5% to 1.8% of the Xeon, which is notable given its drastically lower power envelope. The i7's boost clock of 4.90 GHz is not reflected in a benchmark win, but it does keep the gap extremely tight.

The percentile data places both processors at the 50th percentile among all CPUs in the database. The Xeon's average benchmark score is 2724, while the i7's is 2677. This places them in the same performance tier, with the Xeon's nearest rivals including the AMD Ryzen 7 4700U (0.1% delta) and Intel Core i7-11390H (0.3% delta). The i7's nearest rivals include the Intel Core i5-9500F (0.3% delta) and Intel Core i7-9700T (0.4% delta). Both chips sit in a crowded mid-range segment where small margins separate many products.

Architecture Differences

The architectural gap between these two processors is stark, reflecting nearly a decade of silicon evolution. The Xeon E5-2628L v3 uses the Haswell-EP architecture on a 22 nm process node, released in September 2014. It is built on a 356 mm² die with 2,600 million transistors. The Core i7-1365UE uses Raptor Lake-U, a 10 nm design released in January 2023.

The Xeon has 10 cores and 20 threads with a base clock of 2000.00 MHz and a boost clock of 2.50 GHz. Its cache hierarchy includes 64 KB L1 per core, 256 KB L2 per core, and a large 25 MB shared L3 cache. Memory support is DDR4 with a quad-channel bus, delivering 59.7 GB/s of bandwidth, and it supports ECC memory. PCIe connectivity is Gen 3 with 40 lanes from the CPU. It has no integrated graphics and targets the server/workstation segment.

The Core i7-1365UE has 10 cores and 12 threads (a mix of performance and efficiency cores), with a base clock of 1700.00 MHz and a boost clock of 4.90 GHz. Its cache includes 80 KB L1 per core, 1.25 MB L2 per core, and a 12 MB shared L3. It supports both DDR4 and DDR5 memory over a dual-channel bus, with no ECC support. PCIe is Gen 4 with 8 lanes. It includes Iris Xe Graphics with 80 execution units and is designed for mobile use.

The most consequential differences are thread count (20 vs 12), memory bus width (quad-channel vs dual-channel), process node (22 nm vs 10 nm), and power envelope (75 W vs 15 W). The Xeon's larger L3 cache (25 MB vs 12 MB) and higher memory bandwidth are tailored for server workloads, while the i7's higher boost clock and integrated graphics suit a thin-and-light mobile device.

Head-to-Head Benchmarks

The head-to-head results show the Xeon winning all six tests, but by very slim margins. In Cinebench R15 multicore, the Xeon scores 949 against the i7's 932, a 1.8% delta. In R15 singlecore, the Xeon scores 133 against 131, a 1.5% delta.

Moving to Cinebench R20, the Xeon's multicore score is 3955 versus 3887 for the i7, a 1.7% delta. In singlecore, the Xeon scores 558 versus 548, a 1.8% delta. The R23 results follow the same pattern: multicore 9417 versus 9257 (1.7% delta), and singlecore 1329 versus 1306 (1.8% delta).

The consistency of these deltas is noteworthy. Across every test, the Xeon leads by roughly the same percentage, suggesting that the performance advantage is structural rather than workload-specific. The i7's higher boost clock does not translate into a single-threaded victory, as the Xeon's older but higher-base-clock design (2000 MHz vs 1700 MHz) holds up in these specific benchmarks.

The average benchmark scores reflect the same story: the Xeon averages 2724 points, the i7 averages 2677 points, a difference of 47 points. The Xeon's nearest rival, the AMD Ryzen 7 4700U, sits at 2722 points, just 0.1% behind. The i7's nearest rival, the Intel Core i5-9500F, sits at 2670 points, 0.3% behind. Both chips are firmly in the mid-pack of the database's performance distribution.

The Verdict

The data points to two different buyers. The Intel Xeon E5-2628L v3 is for someone who needs a reliable, server-grade processor with ECC memory support, quad-channel bandwidth, and 20 threads for parallel workloads. Its 75 W TDP is higher, but it is designed for a chassis that can dissipate that heat. The launch MSRP is $1364, and it is now end-of-life, but the benchmark data shows it still holds a slight edge over a much newer mobile chip.

The Intel Core i7-1365UE is for mobile users who need a 15 W processor that can handle everyday tasks, light content creation, and occasional burst workloads. It loses every benchmark to the Xeon, but the margins are within 2%, which is remarkable for a chip that draws one-fifth the power. It is actively produced, supports DDR5, and includes integrated graphics, which the Xeon lacks entirely.

Strictly from the recorded data, the Xeon is the faster processor in every measured test. If absolute performance in Cinebench is the only criterion, the Xeon wins. If power efficiency, platform portability, and modern features matter more, the i7 is the rational pick despite its benchmark deficit. The two chips are not direct competitors; they serve different physical form factors and market segments. The Xeon is a socketed server part, the i7 is a soldered mobile part.
