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

The Intel Xeon D-1712TR and Intel Core i5-8400T are both low-power Intel processors, but they target fundamentally different segments: a server/workstation part against a desktop part. The benchmark data shows a remarkably consistent performance gap, with the Xeon D-1712TR winning all six head-to-head Cinebench tests by margins between 10.1% and 10.4%. Despite the Core i5-8400T having two more physical cores, the Xeon D-1712TR’s architectural advantages and higher clock speeds under load give it a decisive edge in every measured workload.

FAQ

Q: Which processor has a higher average benchmark score?

A: The Intel Xeon D-1712TR has an average benchmark score of 2004, while the Intel Core i5-8400T scores 2001. This places the Xeon D-1712TR 0.1% ahead of the Core i5-8400T in the nearestRivals comparison, where the Core i5-8400T shows a deltaPct of -0.2% relative to the Xeon.

Q: How do the two processors compare in multi-core performance?

A: The Xeon D-1712TR wins all multi-core Cinebench tests. In Cinebench R23 multi-core, it scores 6931 against the Core i5-8400T’s 6282, a 10.3% advantage. The margin is identical in Cinebench R20 multi-core (2911 vs 2638, 10.3%) and slightly smaller in Cinebench R15 multi-core (698 vs 633, 10.3%).

Q: Does the Core i5-8400T have integrated graphics?

A: Yes, the Intel Core i5-8400T includes UHD Graphics 630. The Intel Xeon D-1712TR has no integrated graphics listed in the data, which is typical for a server/workstation part that expects a discrete GPU.

Q: Which processor supports ECC memory?

A: Only the Intel Xeon D-1712TR supports ECC memory. The Core i5-8400T does not list ECC support, reflecting its desktop market segment. The Xeon also uses a triple-channel memory bus, while the Core i5 uses dual-channel.

Q: What is the production status of each processor?

A: The Intel Xeon D-1712TR is listed as "Active" in production, with a release date of 2022-02-23. The Intel Core i5-8400T is marked as "End-of-life," having been released on 2018-04-01.

Architecture Differences

The two processors come from different architectural generations and are built for different sockets. The Intel Xeon D-1712TR is based on the Ice Lake-D architecture, using a 10 nm process node from Intel. It fits into the Intel BGA 2227 socket and belongs to the Xeon D (Ice Lake-D) generation. In contrast, the Intel Core i5-8400T uses the older Coffee Lake architecture on a 14 nm process node, fitting into the Intel Socket 1151.

The core configuration differs substantially. The Xeon D-1712TR has 4 cores and 8 threads, while the Core i5-8400T has 6 cores and 6 threads. This means the Xeon supports simultaneous multithreading (SMT), effectively doubling its thread count, while the Core i5 does not. The Xeon’s base clock is 2000 MHz with a boost clock of 3100 MHz, whereas the Core i5 has a lower base clock of 1700 MHz but a higher boost clock of 3300 MHz.

Cache hierarchies also diverge. The Xeon D-1712TR provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The Core i5-8400T offers 64 KB of L1 per core, 256 KB of L2 per core, and 9 MB of shared L3. The Xeon’s larger per-core L2 cache is notable, though the Core i5 has a slight edge in per-core L1 density relative to its smaller die size of 154 mm².

Memory architecture further separates the two. The Xeon D-1712TR supports triple-channel DDR4 with a peak bandwidth of 57.6 GB/s, while the Core i5-8400T supports dual-channel DDR4 with 42.7 GB/s. The Xeon also supports ECC memory, which the Core i5 lacks. For PCIe, the Xeon uses Gen 4 with 16 lanes (CPU only), while the Core i5 uses Gen 3 with 16 lanes (CPU only). The Xeon has no integrated graphics, while the Core i5 includes UHD Graphics 630.

The Verdict

The data points to a clear choice depending on workload and platform requirements. For anyone building a server or workstation system where ECC memory, higher memory bandwidth, and PCIe Gen 4 are beneficial, the Intel Xeon D-1712TR is the superior option. It wins every benchmark in the head-to-head comparison, delivering roughly 10% more performance in both single-core and multi-core Cinebench tests despite having fewer physical cores. Its active production status also means it remains available for new designs.

For desktop users who need integrated graphics and a lower launch MSRP, the Intel Core i5-8400T has its place. It features UHD Graphics 630, which the Xeon lacks entirely, and its launch MSRP is $182 compared to the Xeon’s $263. However, it loses all six benchmark comparisons, and its end-of-life production status makes it a less forward-looking choice. The Core i5-8400T’s higher boost clock of 3300 MHz does not translate into a performance win, as the Xeon’s 3100 MHz boost still produces higher scores in every test.

The average benchmark scores are nearly identical (2004 vs 2001), placing both at the 45th percentile among all CPUs. But the head-to-head data is unambiguous: the Xeon D-1712TR wins 6 out of 6 tests. If raw compute performance and server-class features are the priority, the Xeon D-1712TR is the pick. If integrated graphics and a lower launch MSRP matter more, the Core i5-8400T remains a viable, though slower, alternative.

Head-to-Head Benchmarks

The head-to-head benchmark results show a uniform pattern: the Intel Xeon D-1712TR wins every single test, with deltas clustering tightly between 10.1% and 10.4%. This consistency suggests the performance gap is systemic rather than workload-specific.

The largest margin is in Cinebench R23 single-core, where the Xeon D-1712TR scores 978 against the Core i5-8400T’s 886, a 10.4% advantage. This is notable because the Core i5-8400T has a higher boost clock (3300 MHz vs 3100 MHz), yet the Xeon still comes out ahead. The architectural efficiency of Ice Lake-D on the 10 nm node appears to overcome the raw clock deficit.

In multi-core workloads, the story is similar. Cinebench R23 multi-core shows the Xeon D-1712TR at 6931 versus 6282 for the Core i5-8400T, a 10.3% win. The same 10.3% margin appears in Cinebench R20 multi-core (2911 vs 2638) and Cinebench R15 multi-core (698 vs 633). The Core i5-8400T’s two extra physical cores are not enough to offset the Xeon’s higher per-core performance and its 8 threads versus the Core i5’s 6 threads.

Single-core results reinforce the pattern. Cinebench R20 single-core shows the Xeon D-1712TR at 410 against 372 for the Core i5-8400T, a 10.2% difference. Cinebench R15 single-core shows 98 versus 89, a 10.1% margin. These are the two smallest deltas in the set, but they still represent a clear and consistent lead for the Xeon.

The Core i5-8400T has additional Geekbench scores in its benchmark list (4011 multi-core, 1100 single-core), but the head-to-head comparison does not include a Geekbench test for the Xeon D-1712TR. Therefore, those numbers cannot be directly compared. The six Cinebench tests are the only shared benchmarks, and the Xeon D-1712TR wins all of them. The final tally is 6 wins for the Xeon D-1712TR and 0 wins for the Core i5-8400T.
