A: Yes. In Cinebench R15 single-core, both chips score exactly 120 points. The head-to-head table lists the Xeon W-2125 as the nominal winner due to tiebreak, but the delta is 0%.

Q: Which chip has more total wins in the head-to-head suite?

A: The Core i7-8850H wins 5 of the 8 benchmark runs, while the Xeon W-2125 wins 3. However, the Core i7-8850H's victories are all narrow, ranging from 0.6% to 0.7% deltas, while the Xeon's wins include a 4.7% margin.

The Verdict

The benchmark data presents an unusually close contest. The average scores differ by only 19 points, and both CPUs occupy the same 49th percentile. Yet the composition of those scores tells different stories. The Core i7-8850H edges ahead in four of the five Cinebench tests, but every margin is tiny — 0.6% or 0.7%. The Xeon W-2125 counters with a decisive 4.7% win in Geekbench multicore and a 1.8% win in Geekbench single-core.

For users prioritizing Geekbench-style workloads, the Xeon W-2125 is the clear pick. Its 4988 multicore score is meaningfully higher, and its 1323 single-core score leads by a solid margin. The Xeon also carries workstation credentials: ECC memory support, a 120W TDP, and a quad-channel DDR4 memory bus with 85.3 GB/s bandwidth. It is built on the Skylake-W architecture with a 484 mm² die.

The Core i7-8850H is the better choice for Cinebench rendering tasks specifically, where it wins four out of five runs. Its 12 MB of L3 cache versus 8.25 MB on the Xeon, combined with 6 cores and 12 threads versus 4 cores and 8 threads, helps it sustain a narrow edge in multi-threaded Cinebench workloads. It also integrates UHD 630 graphics, which the Xeon lacks entirely.

The Core i7-8850H is a mobile part on Intel BGA 1440 with a 45W TDP, making it suitable for laptops. The Xeon W-2125 is a server/workstation part on Intel Socket 2066. The data cannot recommend one universally; it depends entirely on workload. For Geekbench, take the Xeon. For Cinebench, take the Core i7. For everything else, the scores are effectively identical.

Head-to-Head Benchmarks

The most striking result is Geekbench multicore, where the Xeon W-2125 scores 4988 against the Core i7-8850H's 4765. That 4.7% delta is the largest in the entire suite and stands out against the otherwise narrow margins. The Xeon also wins Geekbench single-core at 1323 versus 1300, a 1.8% edge.

Cinebench tells a different story. The Core i7-8850H wins Cinebench R15 multicore with 857 versus 852, a 0.6% margin. It repeats this in Cinebench R20 multicore (3574 versus 3551, 0.6%) and Cinebench R23 multicore (8511 versus 8455, 0.7%). The Core i7 also takes Cinebench R20 single-core (504 versus 501, 0.6%) and Cinebench R23 single-core (1201 versus 1193, 0.7%). The only Cinebench tie is R15 single-core at exactly 120 points each.

The pattern is clear: the Core i7-8850H consistently outperforms in Cinebench but by margins that are within noise. The Xeon W-2125 outperforms decisively in Geekbench, particularly in multicore. The aggregate win count — 5 for the Core i7, 3 for the Xeon — might suggest a Core i7 victory, but the magnitude of the Xeon's Geekbench wins outweighs the Core i7's narrow Cinebench edges in practical terms.

Specification Differences

The two processors diverge sharply on core counts. The Xeon W-2125 has 4 cores and 8 threads, while the Core i7-8850H has 6 cores and 12 threads. Clock speeds also differ: the Xeon runs at 4.00 GHz base and 4.50 GHz boost, whereas the Core i7 runs at 2.70 GHz base and 4.30 GHz boost. The Xeon's higher clocks help it compensate for fewer cores.

TDP is a major differentiator. The Xeon W-2125 draws 120W, while the Core i7-8850H is rated at 45W. That is a 75W gap reflecting their different market segments. The Xeon uses Intel Socket 2066, while the Core i7 uses Intel BGA 1440, meaning the Xeon is socketed for workstations and the Core i7 is soldered for mobile platforms.

Memory configuration also differs substantially. The Xeon W-2125 supports quad-channel DDR4 with 85.3 GB/s bandwidth and ECC memory. The Core i7-8850H supports DDR4 but has no listed memory bus, no memory bandwidth figure, and no ECC support. The Xeon also features 48 PCIe Gen 3 lanes (CPU only), while the Core i7 has no PCIe specification listed.

Integrated graphics present another split: the Core i7-8850H includes UHD 630 graphics, while the Xeon W-2125 has none listed. The Xeon's launch MSRP is $444; the Core i7 has no listed launch MSRP.

Architecture Differences

The Xeon W-2125 uses the Skylake architecture with the Skylake-W codename, manufactured on Intel's 14 nm process with a 484 mm² die size. The Core i7-8850H uses the Coffee Lake architecture with the Coffee Lake-H codename, also on 14 nm but with a much smaller 149 mm² die. Both are fabricated by Intel.

Cache layouts differ significantly. The Xeon W-2125 has 64 KB of L1 per core, 1 MB of L2 per core, and 8.25 MB of shared L3. The Core i7-8850H also has 64 KB of L1 per core but only 256 KB of L2 per core, with a larger 12 MB of shared L3. The Core i7's larger L3 cache partially compensates for its smaller per-core L2.

The Xeon W-2125 is part of the Xeon W (Skylake-W) generation, while the Core i7-8850H belongs to the Core i7 (Coffee Lake-H) generation. The Xeon's market segment is Server/Workstation; the Core i7's is Mobile. Both chips are end-of-life production status. The Xeon W-2125 was released on 2017-08-28, while the Core i7-8850H followed on 2018-04-01. Neither processor has an unlocked multiplier.

Where Each One Wins

The Xeon W-2125 wins decisively in Geekbench workloads. Its 4988 multicore score beats the Core i7-8850H by 4.7%, and its 1323 single-core score leads by 1.8%. This makes it the better option for applications that scale with Geekbench-style integer and floating-point performance. The Xeon also offers ECC memory support, quad-channel bandwidth at 85.3 GB/s, and 48 PCIe Gen 3 lanes — critical for workstation-class reliability and I/O expansion. Its higher base clock of 4.00 GHz gives it an advantage in latency-sensitive single-threaded tasks.

The Core i7-8850H wins in Cinebench rendering workloads, taking four of five Cinebench tests. Its 6-core, 12-thread configuration and 12 MB L3 cache provide a structural advantage in multi-threaded rendering. The Core i7 also includes UHD 630 integrated graphics, enabling display output without a discrete GPU, which is essential for mobile systems. Its 45W TDP makes it viable for laptops, whereas the Xeon's 120W TDP requires a workstation-class cooling solution and power delivery.

For users building a socketed workstation with ECC memory and high-bandwidth storage or GPU expansion, the Xeon W-2125 is the only option that fits. For users needing a mobile processor with integrated graphics and efficient power consumption, the Core i7-8850H is the only option that fits. For pure benchmark performance, the Core i7 wins more tests, but the Xeon wins the tests with the largest margins. The data supports either choice depending on platform and workload priorities.
