Intel Core i7-10875H vs Intel Xeon D-1587 Comparison

Head-to-Head Benchmarks

The benchmark data is decisive: the Intel Core i7-10875H wins every recorded head-to-head comparison against the Intel Xeon D-1587. Across six Cinebench tests, the mobile Core part leads by margins between 5.6% and 6.1%, with no single test favoring the Xeon.

The largest gap appears in Cinebench R15 single-core, where the i7-10875H scores 174 against 164 for the Xeon D-1587, a 6.1% advantage. The same test in multi-core shows 1233 versus 1167, a 5.7% lead. In Cinebench R20, the pattern holds: single-core 725 against 686 (5.7% ahead), multi-core 5138 versus 4865 (5.6% ahead). Cinebench R23 repeats the story with single-core 1727 versus 1635 (5.6% ahead) and multi-core 12234 versus 11585 (5.6% ahead). Every head-to-head result is consistent, with the i7-10875H winning all six recorded matchups.

The overall average benchmark score reinforces this. The i7-10875H averages 3432 across its benchmark suite, while the Xeon D-1587 averages 3350. Both processors sit at the 54th percentile among all CPUs in the database, so they occupy the same performance tier overall, but the margin in direct comparisons favors the mobile chip. The Xeon's nearest rivals in the database include the Intel Core i7-7800X (average 3333, delta 0.5%), the AMD Ryzen 7 5800U (average 3369, delta -0.5%), and the Intel Core i5-11400T (average 3309, delta 1.2%). The i7-10875H sits alongside the Intel Core i9-9880H (average 3433, delta 0%), the AMD Ryzen 3 PRO 5350G (average 3441, delta -0.3%), and the AMD Ryzen 5 4600HS (average 3444, delta -0.3%).

These are not dramatic gaps, but they are uniform. The data shows that in every Cinebench generation, from R15 through R23, the i7-10875H maintains a lead of roughly 5.6% to 6.1%. This consistency suggests a general performance advantage rather than a workload-specific quirk. The Xeon cannot point to any single benchmark where it pulls ahead.

Architecture Differences

The two chips come from different Intel families and different eras. The i7-10875H is a Comet Lake-H part, built on the 14 nm process with a die size of 177.5 mm². The Xeon D-1587 is a Broadwell-DE server chip, also on 14 nm, but with a larger die at 246 mm² and a transistor count of 3,200 million. Both are manufactured by Intel.

Core and thread counts differ substantially. The Xeon D-1587 has 16 cores and 32 threads, exactly double the 8 cores and 16 threads of the i7-10875H. Despite having twice the core count, the Xeon cannot convert that into a benchmark win, which points to a large clock speed disadvantage. The i7-10875H has a base clock of 2.30 GHz and a boost clock of 5.10 GHz. The Xeon D-1587 starts at 1.70 GHz base and boosts to 2.30 GHz. That boost ceiling on the Xeon is barely above the i7's base clock, and the single-core benchmark results show the consequences.

Cache layouts also differ. Both chips have 64 KB of L1 per core and 256 KB of L2 per core. The L3 cache is organized differently: the i7-10875H has 16 MB shared, while the Xeon D-1587 has 1.5 MB per core, which across 16 cores amounts to a larger total, though the database does not list a shared total for the Xeon. The Xeon supports DDR3 and DDR4 memory with dual-channel access and ECC memory enabled. The i7-10875H supports DDR4 only, also dual-channel, with no ECC support. Memory bandwidth for the i7-10875H is listed at 46.9 GB/s; the Xeon has no bandwidth figure in the database.

PCIe connectivity differs as well. The i7-10875H provides Gen 3 with 16 lanes from the CPU. The Xeon D-1587 provides Gen 3 with 24 lanes. The i7-10875H includes integrated UHD Graphics, while the Xeon has no integrated graphics. The i7 is a mobile part on Intel BGA 1440, while the Xeon is a server/workstation part on Intel BGA 1667. Neither chip has an unlocked multiplier.

Release timing shows the generation gap: the i7-10875H launched in April 2020, while the Xeon D-1587 launched in February 2016. The Xeon is a server-oriented part from an earlier architecture generation, and the data suggests that its extra cores are offset by lower clocks and older microarchitecture.

FAQ

Q: Which processor wins in multi-core performance?

A: The Intel Core i7-10875H wins all multi-core Cinebench tests. It scores 1233 in R15 multi-core versus 1167 for the Xeon D-1587, 5138 versus 4865 in R20, and 12234 versus 11585 in R23. The margin is 5.6% to 5.7% in each case.

Q: Does the Xeon D-1587's higher core count give it an advantage?

A: No. The Xeon D-1587 has 16 cores and 32 threads, double the i7-10875H's 8 cores and 16 threads. Yet the benchmark data shows the i7-10875H winning every recorded test. The Xeon's lower clock speeds, 1.70 GHz base and 2.30 GHz boost, prevent its core advantage from translating into higher scores.

Q: How do the single-core scores compare?

A: The i7-10875H leads in all single-core tests. It scores 174 versus 164 in Cinebench R15, 725 versus 686 in R20, and 1727 versus 1635 in R23. The deltas range from 5.6% to 6.1%.

Q: What memory types does each processor support?

A: The i7-10875H supports DDR4 only, with dual-channel access and no ECC support. The Xeon D-1587 supports both DDR3 and DDR4, also dual-channel, and includes ECC memory support.

Q: What is the average benchmark score for each chip?

A: The i7-10875H has an average benchmark score of 3432, while the Xeon D-1587 averages 3350. Both sit at the 54th percentile among all CPUs in the database.

Q: Do both processors use the same manufacturing process?

A: Yes. Both are built on Intel's 14 nm process. The i7-10875H uses a 177.5 mm² die, while the Xeon D-1587 uses a larger 246 mm² die with 3,200 million transistors.

The Verdict

The data points to a clear conclusion: the Intel Core i7-10875H is the better performer in every benchmark the database records. It wins all six head-to-head Cinebench comparisons, holds a higher average benchmark score (3432 versus 3350), and delivers consistent leads of 5.6% to 6.1% across both single-core and multi-core tests.

The Xeon D-1587's main asset is its core count: 16 cores and 32 threads, double the i7-10875H's 8 cores and 16 threads. But the benchmark results show that this does not produce a win in any recorded test. The Xeon's clocks, 1.70 GHz base and 2.30 GHz boost, are far below the i7's 2.30 GHz base and 5.10 GHz boost, and the older Broadwell architecture does not compensate.

The Xeon does bring server-oriented features that the i7 lacks: ECC memory support, support for both DDR3 and DDR4, and 24 PCIe Gen 3 lanes versus 16. It also has a larger die and a listed transistor count, reflecting its different design goals. For buyers choosing between these two, the i7-10875H offers superior benchmark performance across the board, while the Xeon D-1587 offers ECC memory and more PCIe lanes for server workloads. The launch MSRP for the i7-10875H is $450; the Xeon D-1587 has a launch MSRP of 1549.

Where Each One Wins

The benchmark data gives the i7-10875H the win in every recorded test category. It is ahead in Cinebench R15, R20, and R23, in both single-core and multi-core modes. The margins are consistent, between 5.6% and 6.1%, which indicates a steady performance edge rather than a workload-specific advantage. The i7-10875H also holds the higher average benchmark score, 3432 versus 3350.

The Xeon D-1587 does not win any benchmark in the head-to-head data. Its case rests on features outside the benchmark suite. It supports ECC memory, which is important for reliability in server and workstation environments. It supports both DDR3 and DDR4 memory, giving it flexibility with existing memory infrastructure. It provides 24 PCIe Gen 3 lanes, more than the i7-10875H's 16 lanes. It also has double the core count, 16 cores and 32 threads, which could matter in workloads that scale beyond what the benchmarks measure, though the recorded tests show no such advantage.

The use-case split is therefore straightforward. For general computing, mobile use, and any workload measured by Cinebench, the i7-10875H is the stronger choice. For server deployments where ECC memory and additional PCIe lanes matter more than raw benchmark scores, the Xeon D-1587 has specific advantages. The data, however, is unambiguous on performance: the i7-10875H wins all six head-to-head tests and has the higher average score.
