Intel Core i5-1038NG7 vs Intel Xeon D-1540 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Xeon D-1540 wins every single recorded head-to-head test against the Intel Core i5-1038NG7. Across six Cinebench comparisons, the Xeon D-1540 takes a clean sweep with a 6 to 0 win margin, and the margins are remarkably consistent.

In Cinebench R15 multicore, the Xeon D-1540 scores 859 against the Core i5-1038NG7's 750, a 14.5% advantage. The single-core test for R15 shows the Xeon D-1540 at 121 versus 105, a 15.2% lead. Moving to Cinebench R20, the multicore result puts the Xeon D-1540 at 3583 against 3125, a 14.7% gap, while the single-core result is 505 versus 441, a 14.5% difference. In Cinebench R23, the multicore scores are 8531 for the Xeon D-1540 and 7441 for the Core i5-1038NG7, a 14.6% edge, and the single-core test shows 1204 versus 1050, again a 14.7% gap.

The patterns are striking. The Xeon D-1540's lead hovers between 14.5% and 15.2% across every test, regardless of whether the workload is single-threaded or multi-threaded. This consistency suggests a fundamental performance advantage rather than a workload-specific quirk. The Core i5-1038NG7 does post additional Geekbench results in the database, with a multicore score of 4919 and a single-core score of 1354, but no corresponding Geekbench data exists for the Xeon D-1540, so those cannot be compared directly.

The average benchmark scores tell a similar story. The Xeon D-1540 averages 2467 across all recorded benchmarks, while the Core i5-1038NG7 averages 2398, a gap of roughly 2.9%. Both processors sit at the 48th percentile among all CPUs in the database, which places them in the same performance tier overall, but the head-to-head results show the Xeon D-1540 as the clear winner in every direct comparison.

For context, the Xeon D-1540's nearest rivals in the database include the Intel Core i3-12100TE with an average score of 2475, just 0.3% ahead, and the Intel Core i5-8600 at 2454, a 0.5% gap behind. The Core i5-1038NG7's nearest rivals include the Intel Xeon E5-2630L v3 at 2409, which is 0.5% ahead, and the AMD Ryzen 3 PRO 4450U at 2413, 0.6% ahead. These neighboring scores reinforce that both chips occupy similar overall performance territory, even though the direct head-to-head favors the Xeon D-1540 decisively.

Architecture Differences

The two processors come from entirely different design lineages. The Intel Xeon D-1540 uses the Broadwell architecture, specifically the Xeon D (Broadwell-DE) generation, built on a 14 nm process node. The Intel Core i5-1038NG7 uses the Ice Lake architecture from the Core i5 (Sunny Cove-U) generation, built on a 10 nm process node. The process node difference is meaningful: the Core i5-1038NG7's 10 nm process represents a newer manufacturing technology compared to the Xeon D-1540's 14 nm node.

Core counts diverge sharply. The Xeon D-1540 offers 8 cores and 16 threads, while the Core i5-1038NG7 provides 4 cores and 8 threads. This doubling of cores and threads explains the Xeon D-1540's multicore performance advantage, but interestingly, the single-core tests also favor the Xeon D-1540 despite the Core i5-1038NG7's higher boost clock of 3.80 GHz versus 2.60 GHz. Both processors have a base clock of 2000.00 MHz.

Cache hierarchies differ in structure. The Xeon D-1540 has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 1.5 MB of L3 cache per core. The Core i5-1038NG7 has 80 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. The per-core L3 allocation on the Xeon D-1540 totals 12 MB across 8 cores, while the Core i5-1038NG7 shares a single 6 MB pool.

The die sizes and transistor counts reveal the manufacturing scale. The Xeon D-1540 has a die size of 246 mm² and contains 3,200 million transistors. The Core i5-1038NG7's die is 123 mm², with no transistor count recorded in the database. The Xeon D-1540's larger die accommodates its additional cores and server-oriented features.

Memory support also differentiates the two. The Xeon D-1540 supports both DDR3 and DDR4 memory in a dual-channel configuration, and it includes ECC memory support. The Core i5-1038NG7 supports only DDR4 memory, also in dual-channel, but lacks ECC capability. The Core i5-1038NG7 does have a recorded memory bandwidth of 51.2 GB/s, while no memory bandwidth figure exists for the Xeon D-1540.

PCIe connectivity and integrated graphics add further separation. The Xeon D-1540 provides PCIe Gen 3 with 24 lanes (CPU only), and it has no integrated graphics. The Core i5-1038NG7 offers PCIe Gen 3 with no lane count specified, and it includes Iris Plus integrated graphics. The Xeon D-1540 targets the server and workstation segment, while the Core i5-1038NG7 is designed for mobile platforms. The Xeon D-1540 remains active in production, while the Core i5-1038NG7 is marked as end-of-life. Their release dates are also far apart: the Xeon D-1540 launched in March 2015, and the Core i5-1038NG7 arrived in May 2020.

Release dates are March 2015 for the Xeon D-1540 and May 2020 for the Core i5-1038NG7. The launch MSRP for the Xeon D-1540 is $581, while the Core i5-1038NG7 has a launch MSRP of $320. Both processors have locked multipliers.

The Verdict

The data points to the Intel Xeon D-1540 as the superior performer in every recorded benchmark comparison. The 14.5% to 15.2% lead across all Cinebench tests, including single-core workloads, gives it a decisive advantage that the Core i5-1038NG7 cannot overcome despite its newer architecture and higher boost clock. The Xeon D-1540's 8 cores and 16 threads provide a structural edge, but the single-core wins show that its per-thread performance also exceeds the Core i5-1038NG7's.

The Core i5-1038NG7 does have its own advantages in the specification sheet: a 10 nm process, a smaller die at 123 mm², a lower TDP of 28 watts, integrated Iris Plus graphics, and a higher boost clock of 3.80 GHz. It also carries a lower launch MSRP of $320 compared to the Xeon D-1540's $581. However, in terms of raw benchmark performance, the Xeon D-1540 wins outright.

The average benchmark scores place both chips at the same 48th percentile among all CPUs, and the Xeon D-1540's average of 2467 is only about 2.9% above the Core i5-1038NG7's 2398. This suggests that in a broader database context, the two are closer than the head-to-head results imply, but for any direct comparison between these two specific processors, the Xeon D-1540 is the clear choice based on performance data.

Where Each One Wins

The Intel Xeon D-1540 wins in every scenario where benchmark performance matters. Its 14.5% lead in Cinebench R15 multicore, 14.7% lead in R20 multicore, and 14.6% lead in R23 multicore make it the better option for multi-threaded workloads like rendering, compilation, or server-side processing. The single-core wins, ranging from 14.5% to 15.2%, extend its advantage to lightly threaded tasks as well. For users who need ECC memory support, DDR3 or DDR4 compatibility, and a server or workstation platform, the Xeon D-1540 is the only one of the two that fits those requirements.

The Intel Core i5-1038NG7 does not win any recorded benchmark comparison, but it holds advantages in other dimensions. Its 10 nm process node and 123 mm² die size indicate a more modern and compact manufacturing approach. The 28 watt TDP makes it the lower-power option, and the integrated Iris Plus graphics eliminate the need for a separate GPU in mobile systems. Its 3.80 GHz boost clock is substantially higher than the Xeon D-1540's 2.60 GHz, even though the benchmark results do not translate that clock advantage into higher scores. The Core i5-1038NG7's mobile market segment and 51.2 GB/s memory bandwidth suggest it is built for portable computing, where the Xeon D-1540's server orientation is not applicable.

The use-case split is clear from the data. Choose the Xeon D-1540 for performance-critical server or workstation tasks where ECC memory and additional cores are required, and where the higher TDP and lack of integrated graphics are acceptable. Choose the Core i5-1038NG7 for mobile or compact systems where integrated graphics, a lower TDP, and a newer process node matter more than raw benchmark scores. The benchmark results do not favor the Core i5-1038NG7 in any direct comparison, but its specification profile supports different deployment scenarios.
