Intel Core i5-8400H vs Intel Xeon D-1712TR Comparison

The Intel Xeon D-1712TR and the Intel Core i5-8400H are both 4-core, 8-thread processors, yet they target entirely different market segments. The Xeon D-1712TR is a server/workstation part built on Intel’s 10 nm Ice Lake-D process, while the i5-8400H is a mobile processor from the 14 nm Coffee Lake-H family, now end-of-life. Despite these architectural and platform differences, their aggregate benchmark scores are nearly identical: the Xeon D-1712TR posts an average benchmark score of 2004, while the i5-8400H sits at 2003. The data shows a dead heat in overall performance, but a closer look at individual Cinebench tests reveals a consistent, if modest, edge for the Xeon part.

Head-to-Head Benchmarks

The head-to-head comparison is dominated by the Intel Xeon D-1712TR, which wins all six benchmark comparisons. The margins are remarkably uniform, hovering between 8.4% and 8.9% across every test. In Cinebench R15 multicore, the Xeon D-1712TR scores 698 against the i5-8400H’s 644, a delta of 8.4%. The single-core variant of the same test shows a slightly larger gap: 98 versus 90, or 8.9% in favor of the Xeon. This pattern repeats in Cinebench R20, where the Xeon D-1712TR delivers 2911 multicore and 410 single-core points, compared to 2684 and 378 for the i5-8400H—again an 8.5% advantage in both metrics.

The most recent Cinebench R23 results continue the trend. The Xeon D-1712TR achieves 6931 multicore and 978 single-core points, while the i5-8400H trails with 6392 and 902, respectively. The delta is 8.4% in both cases. Notably, the i5-8400H does have additional Geekbench scores in its benchmark list—3656 multicore and 1281 single-core—but the Xeon D-1712TR has no corresponding Geekbench entries in the data, so no direct comparison is possible for that suite.

What is striking is the consistency of the performance gap. The Xeon D-1712TR’s advantage does not shrink or expand with workload scaling; it remains pinned near 8.5%. This suggests a fundamental per-clock efficiency advantage rather than a difference that varies with thread count or cache behavior. The i5-8400H has a higher base clock (2.50 GHz versus 2.00 GHz) and a substantially higher boost clock (4.10 GHz versus 3.10 GHz), yet it still loses every single-core test. The Xeon D-1712TR’s Ice Lake architecture appears to deliver more instructions per clock, overcoming the i5-8400H’s clock speed advantage.

Given the near-identical average scores, the nearestRivals data shows a deltaPct of 0 between the two parts, meaning their overall performance is statistically indistinguishable. The i5-8400H’s nearest rivals include the AMD Ryzen 7 2800H at a 0.1% delta, while the Xeon D-1712TR sits alongside the Intel Core i5-8400T in the same 0.1% range. Neither part has a decisive overall lead; the Xeon D-1712TR’s wins are concentrated in the Cinebench suite, which may not reflect all real-world workloads.

The Verdict

The benchmark data presents a clear but narrow verdict. The Intel Xeon D-1712TR wins every head-to-head Cinebench comparison, with margins between 8.4% and 8.9%. For anyone whose workload is dominated by Cinebench-style rendering tasks, the Xeon D-1712TR is the better choice, despite its lower clock speeds. The 10 nm Ice Lake-D architecture proves more efficient per clock than the 14 nm Coffee Lake-H design, and this shows up in both single-core and multi-core tests.

However, the overall average benchmark scores tell a different story. The Xeon D-1712TR’s average of 2004 is just a single point above the i5-8400H’s 2003, and the deltaPct in the nearestRivals data is 0. This means that across a broader benchmark suite—including the i5-8400H’s Geekbench results, which the Xeon lacks—the two parts are effectively tied. The i5-8400H’s higher boost clock of 4.10 GHz likely helps in workloads that are not captured by the Cinebench suite, offsetting the Xeon’s architectural advantage.

The production status also matters. The Xeon D-1712TR is listed as Active, released in 2022, while the i5-8400H is End-of-life, released in 2018. The Xeon D-1712TR also supports ECC memory and has a triple-channel memory bus with 57.6 GB/s bandwidth, whereas the i5-8400H has no ECC support and no memory bus or bandwidth data listed. The Xeon D-1712TR is the more future-proof and server-appropriate option, while the i5-8400H is a legacy mobile part.

Who should pick which? From the data alone, the Xeon D-1712TR is the better performer in the tested benchmarks and carries a 40 W TDP versus the i5-8400H’s 45 W, a 12.5% lower power draw. The i5-8400H offers integrated UHD 630 graphics, which the Xeon D-1712TR lacks entirely. For a system requiring a GPU-less server CPU with ECC support, the Xeon D-1712TR is the logical choice. For a mobile or embedded application where integrated graphics are necessary, the i5-8400H has that capability, even if it loses on raw Cinebench performance.

Specification Differences

The two processors differ in several key specifications, starting with clocks. The Xeon D-1712TR has a base clock of 2.00 GHz and a boost clock of 3.10 GHz, while the i5-8400H runs at 2.50 GHz base and 4.10 GHz boost. The i5-8400H has higher clocks in both cases. The Xeon D-1712TR has a lower TDP of 40 W versus 45 W for the i5-8400H.

The sockets are different: the Xeon D-1712TR uses Intel BGA 2227, while the i5-8400H uses Intel BGA 1440. The Xeon supports DDR4 memory with a triple-channel bus and 57.6 GB/s bandwidth, plus ECC memory; the i5-8400H supports DDR4 but has no listed memory bus, bandwidth, or ECC support. The Xeon has PCIe Gen 4 with 16 lanes (CPU only), while the i5-8400H has no PCIe data listed.

The Xeon D-1712TR has no integrated graphics, while the i5-8400H includes UHD 630 graphics. The Xeon is marked as a Server/Workstation part and is Active in production, with a release date of 2022 and a launch MSRP of $263. The i5-8400H is a Mobile part, End-of-life, released in 2018, with no launch MSRP listed. Their part numbers also differ: SRM1G for the Xeon, SR3Z1 for the i5.

Architecture Differences

The architectural gap is significant. The Xeon D-1712TR is built on Ice Lake-D, a 10 nm process, while the i5-8400H uses Coffee Lake-H on a 14 nm process. Both are manufactured by Intel, but the newer node gives the Xeon a transistor density advantage. The Xeon’s cache hierarchy is also different: it has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. The i5-8400H has 64 KB L1 per core, 256 KB L2 per core, and a larger 12 MB shared L3. Despite having more total L3 cache, the i5-8400H loses in Cinebench, suggesting the Xeon’s memory bandwidth and per-core cache are more effective.

The Xeon D-1712TR’s architecture supports a triple-channel memory bus with 57.6 GB/s bandwidth and ECC, which is absent on the i5-8400H. The Xeon also supports PCIe Gen 4 with 16 lanes, while the i5-8400H has no PCIe specification listed. The i5-8400H’s die size is listed as 126 mm², while the Xeon D-1712TR has no die size data. The i5-8400H features integrated UHD 630 graphics, which the Xeon D-1712TR completely lacks, reflecting its server-oriented design. The Xeon is a 2022 part with a 10 nm process, whereas the i5-8400H is a 2018 part on 14 nm—this generational leap is the primary reason the Xeon can achieve higher performance at lower clocks and lower TDP.
