Intel Core i7-10710U vs Intel Xeon D-1557 Comparison

The Intel Xeon D-1557 and Intel Core i7-10710U are both 14nm Intel parts, but they are built for entirely different worlds. The benchmark data shows the Xeon D-1557 winning every single head-to-head test, yet the margins are remarkably slim. In fact, despite the Xeon's 12-core/24-thread configuration doubling the Core i7's 6-core/12-thread setup, the performance gap never exceeds 1.8%. This creates an unusual dynamic where architectural efficiency and clock speed almost completely negate a massive core-count advantage.

Head-to-Head Benchmarks

The Xeon D-1557 sweeps all six Cinebench comparisons, but the victories are narrow. In Cinebench R15 multicore, the Xeon scores 795 against the Core i7's 783, a 1.5% lead. The single-core result is slightly more pronounced: 112 versus 110, a 1.8% edge for the Xeon. These are the tightest margins in the entire comparison, showing that the Core i7's higher boost clock can nearly match the Xeon's greater core count in lightly threaded workloads.

Moving to Cinebench R20, the pattern holds. The Xeon posts 3314 in multicore versus 3265 for the Core i7, again a 1.5% difference. The single-core scores of 467 and 460 produce the same 1.5% delta. In Cinebench R23, the Xeon's 7892 multicore score edges out the Core i7's 7774, maintaining that consistent 1.5% gap. The R23 single-core result is 1114 against 1097, another 1.5% lead.

The consistency is striking. Every single multicore test shows exactly 1.5% separation, and single-core tests range from 1.5% to 1.8%. This suggests the Xeon D-1557's advantage comes from its thread count scaling, but the Core i7-10710U's 4.70 GHz boost clock (versus the Xeon's 2.10 GHz) keeps it within striking distance. The data indicates that the Xeon D-1557 is the outright winner in every benchmark, but the Core i7-10710U is not far behind despite having half the cores and threads.

When placed against their respective nearest rivals, both CPUs sit at the 47th percentile of all processors. The Xeon D-1557's average benchmark score of 2282 is nearly identical to the Intel Xeon E5-2629 v3's 2283 (0% delta) and slightly ahead of the Intel Core i3-10305's 2264 (0.8% delta). The Core i7-10710U's average of 2248 is within 0.1% of the AMD Ryzen 5 PRO 1500's 2246 and trails the Intel Core i7-1068NG7's 2259 by 0.5%. These rival comparisons highlight that both CPUs are firmly mid-pack performers, with the Xeon D-1557 holding a marginal overall advantage.

Architecture Differences

The Xeon D-1557 is built on the Broadwell architecture, specifically the Broadwell-DE generation, and targets the server and workstation segment. It uses the Intel BGA 1667 socket and carries a 45 W TDP. In contrast, the Core i7-10710U uses the Comet Lake architecture (Comet Lake-U generation), fits into the Intel BGA 1440 socket, and consumes just 25 W. Both are manufactured on Intel's 14 nm process node, but the Xeon D-1557 packs 3,200 million transistors on a 246 mm² die, while the Core i7's transistor count and die size are not specified in the data.

The cache layouts diverge significantly. The Xeon D-1557 provides 64 KB of L1 and 256 KB of L2 per core, plus 1.5 MB of L3 per core, which amounts to 18 MB total across 12 cores. The Core i7-10710U also has 64 KB L1 and 256 KB L2 per core, but its L3 is 12 MB shared across all six cores. This means the Xeon has more total L3 cache, but the Core i7's shared design can be more flexible for single-threaded access.

Memory support is similar — both accept DDR3 and DDR4 — but the Xeon D-1557 supports ECC memory, a critical feature for server reliability, while the Core i7-10710U does not. The Xeon also offers PCIe Gen 3 with 24 lanes from the CPU, whereas the Core i7's PCIe configuration is not listed. The Core i7 includes integrated UHD Graphics, while the Xeon D-1557 has no integrated graphics at all. The Xeon D-1557 was released on 2016-02-23 and remains active in production, while the Core i7-10710U launched on 2019-08-20 and is now end-of-life.

Specification Differences

The two processors differ in several key specification fields. The Xeon D-1557 offers 12 cores and 24 threads versus the Core i7-10710U's 6 cores and 12 threads. Base clocks are 1500 MHz for the Xeon and 1100 MHz for the Core i7, but boost clocks reverse the order: 2.10 GHz for the Xeon and 4.70 GHz for the Core i7. The TDP is 45 W for the Xeon and 25 W for the Core i7. The Xeon uses the Intel BGA 1667 socket, while the Core i7 uses Intel BGA 1440.

The architectures are entirely different: Broadwell for the Xeon D-1557 versus Comet Lake for the Core i7-10710U. The Xeon's codename is Broadwell, while the Core i7's is Comet Lake-U. The Xeon has a die size of 246 mm² and 3,200 million transistors, whereas the Core i7 has no specified die size or transistor count. L3 cache differs structurally: the Xeon provides 1.5 MB per core, while the Core i7 offers 12 MB shared. ECC memory support is exclusive to the Xeon, and integrated graphics are exclusive to the Core i7 (UHD Graphics). The Xeon provides 24 PCIe Gen 3 lanes, while the Core i7's PCIe details are absent. The Xeon targets the server/workstation segment, and the Core i7 targets mobile. Production status differs: the Xeon is active, and the Core i7 is end-of-life.

Where Each One Wins

The Xeon D-1557 wins all six head-to-head benchmarks, making it the clear choice for raw compute performance in every Cinebench test. Its 12 cores and 24 threads give it a structural advantage in multi-threaded workloads, and it also edges out the Core i7 in single-threaded tests despite the Core i7's much higher boost clock. The Xeon's ECC memory support and 24 PCIe Gen 3 lanes make it suited for server and workstation deployments where data integrity and I/O expansion are priorities. Its active production status also means it remains available for new systems.

The Core i7-10710U, despite losing every benchmark, has its own strengths. Its 25 W TDP is nearly half the Xeon's 45 W, making it far more suitable for power-constrained mobile designs. The integrated UHD Graphics eliminate the need for a discrete GPU in basic display tasks, which the Xeon cannot offer. The Core i7's 4.70 GHz boost clock brings it within 1.5% of the Xeon's multi-core scores while using significantly less power. For a mobile platform, the Core i7-10710U is the only viable option between the two, as the Xeon's server-oriented feature set does not translate to laptop usage.

The Verdict

The data is unambiguous: the Intel Xeon D-1557 wins every benchmark by a margin between 1.5% and 1.8%. If raw performance is the sole criterion, the Xeon D-1557 is the superior processor. Its double core count and thread count deliver a measurable, if modest, lead across all Cinebench versions, and its ECC memory support plus active production status make it the logical choice for server and workstation builds.

However, the Core i7-10710U is not an inferior product in context. It achieves nearly identical scores while consuming 45% less power (25 W versus 45 W), and its integrated graphics make it a complete mobile solution. The Core i7's end-of-life status is a concern for new designs, but its boost clock of 4.70 GHz shows that clock speed can compensate for core count. For a mobile workload where battery life and integrated graphics matter, the Core i7-10710U is the appropriate pick. For a static server environment where ECC and PCIe lanes are required, the Xeon D-1557 is the clear winner. The benchmark results show that the Xeon D-1557 is the faster chip, but the Core i7-10710U is the more versatile one for its target market.
