Intel Core i3-8109U vs Intel Xeon W-2102 Comparison

The Intel Xeon W-2102 and the Intel Core i3-8109U occupy opposite ends of the Intel lineup, yet their average benchmark scores sit remarkably close together. The Xeon W-2102, a server and workstation part with 4 cores and 4 threads, records an average benchmark score of 1264, while the mobile-focused Core i3-8109U, with 2 cores and 4 threads, scores 1235. The database places the Xeon in the 35th percentile of all CPUs, and the Core i3 in the 34th percentile, meaning both processors deliver similar overall performance for their respective markets. However, the similarity ends there: the Xeon wins 5 of the 6 head-to-head benchmark comparisons, while the Core i3 wins only 1, specifically in Cinebench R15 single-core. This is not a case of one chip being universally faster; it is a case of two different design philosophies producing different performance profiles.

The Verdict

The data points to a clear split: choose the Intel Xeon W-2102 for any workload that leverages multiple cores, sustained throughput, or server-class features. Its Cinebench R23 multi-core score of 4370 versus the Core i3-8109U’s 3544 represents a 23.3% advantage, and this pattern repeats across every multi-core test in the database. The Xeon also wins in Cinebench R20 single-core (259 vs 210) and R23 single-core (617 vs 500), which contradicts the expectation that a lower-clocked, higher-TDP part would fall behind in single-threaded tasks.

Choose the Intel Core i3-8109U if your priority is a specific single-core workload like the Cinebench R15 single-core test, where it scores 138.65 against the Xeon’s 62, a 55.3% deficit for the Xeon. This extreme result likely stems from the Xeon’s lack of a boost clock (base clock 2.90 GHz, no boost listed) versus the Core i3’s boost capability (3.00 GHz base, 3.60 GHz boost). The Core i3 also comes with integrated graphics (Iris Pro Plus), making it the only one of the two that can output video without a discrete GPU. For a compact mobile system where single-thread responsiveness matters more than multi-core grunt, the Core i3 is the sensible pick. For a workstation or server environment where ECC memory, quad-channel bandwidth (85.3 GB/s), and multi-core scaling matter, the Xeon W-2102 is the obvious choice, despite its higher 120 W TDP and end-of-life status.

Where Each One Wins

The Xeon W-2102 dominates in multi-threaded rendering tasks. In Cinebench R15 multi-core, it scores 440 versus 357 (a 23.2% win). In R20 multi-core, it scores 1835 versus 1488 (23.3%). In R23 multi-core, it scores 4370 versus 3544 (23.3%). The Xeon also wins in single-core tests from R20 and R23, with margins of 23.3% and 23.4% respectively. These wins are consistent across all Cinebench versions, indicating that the Xeon’s architecture and memory subsystem provide a stable advantage in both lightly and heavily threaded CPU work.

The Core i3-8109U’s sole victory comes in Cinebench R15 single-core, where it scores 138.65 versus the Xeon’s 62. That is a massive 55.3% difference, and it is the only benchmark in the head-to-head set where the Core i3 leads. This win is likely due to the Core i3’s higher boost clock (3.60 GHz) and newer Kaby Lake architecture, which has better single-thread efficiency than the older Skylake-W design. The Core i3 also has a lower TDP (28 W versus 120 W), making it suitable for thin-and-light laptops, while the Xeon requires a desktop or workstation platform with active cooling.

The database also shows that the Core i3 has additional Geekbench results (2454 multi-core, 1188 single-core) that the Xeon does not have, but these are not part of the head-to-head comparison, so they do not affect the win tally.

Architecture Differences

The Xeon W-2102 is built on the Skylake-W architecture, a derivative of Skylake, using a 14 nm process node from Intel. Its die size is 484 mm², which is significantly larger than the Core i3’s 123 mm². The Xeon has 4 cores and 4 threads, with a base clock of 2.90 GHz and no boost clock listed. It features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 8.25 MB of shared L3 cache. Memory support is DDR4 with a quad-channel bus, delivering 85.3 GB/s of bandwidth, and ECC memory is supported. The Xeon uses the Intel Socket 2066, provides Gen 3 PCIe with 48 lanes (CPU only), and has no integrated graphics. It targets the server and workstation segment, is end-of-life, and launched with an MSRP of $202.

The Core i3-8109U is based on Kaby Lake, specifically the Kaby Lake-U Refresh generation, also on a 14 nm node. Its die size is 123 mm². It has 2 cores and 4 threads, with a base clock of 3.00 GHz and a boost clock of 3.60 GHz. Cache configuration includes 64 KB L1 per core, 256 KB L2 per core, and 4 MB shared L3. Memory support is DDR4, but the database records no memory bus width or bandwidth figures. ECC memory is not supported. The Core i3 uses Intel BGA 1356, has no PCIe lane count listed, and includes integrated graphics (Iris Pro Plus). It is a mobile part, currently active in production, and was released later than the Xeon (April 2018 versus August 2017).

The key differences are: core count (4 vs 2), L2 cache per core (1 MB vs 256 KB), L3 cache (8.25 MB vs 4 MB), memory bus (quad-channel vs unspecified), ECC support (yes vs no), socket (2066 vs BGA 1356), integrated graphics (none vs Iris Pro Plus), TDP (120 W vs 28 W), and production status (end-of-life vs active). These architectural choices explain the benchmark outcomes: the Xeon’s larger caches and quad-channel memory benefit multi-core tasks, while the Core i3’s higher boost clock and newer core design give it an edge in one specific single-thread test.

Q: Which processor has integrated graphics?

A: The Intel Core i3-8109U has integrated graphics (Iris Pro Plus). The Intel Xeon W-2102 has no integrated graphics, so it requires a discrete GPU for display output.

Q: What is the memory bandwidth difference?

A: The Xeon W-2102 has a quad-channel memory bus with 85.3 GB/s bandwidth. The Core i3-8109U has no memory bus or bandwidth figures recorded in the database, so no comparison can be made beyond the fact that both support DDR4.

Q: Which processor has a higher base clock?

A: The Core i3-8109U has a base clock of 3.00 GHz, while the Xeon W-2102 has a base clock of 2.90 GHz. The Core i3 also has a boost clock of 3.60 GHz, whereas the Xeon has no boost clock listed.

Head-to-Head Benchmarks

The head-to-head data reveals a consistent pattern: the Xeon W-2102 leads in five of six tests, with the Core i3-8109U taking only one. The largest margin in favor of the Xeon is 23.4% in Cinebench R23 single-core (617 versus 500). The same margin appears in R20 single-core (259 versus 210, 23.3%) and R20 multi-core (1835 versus 1488, 23.3%). In R23 multi-core, the Xeon scores 4370 versus 3544, again 23.3% higher. In R15 multi-core, the Xeon leads 440 versus 357, which is 23.2% higher.

The Core i3’s win in R15 single-core is stark: 138.65 versus 62, a delta of 55.3% in its favor. This single result skews the overall average benchmark scores, but the database’s percentile rankings still place the Xeon slightly higher (35th vs 34th percentile). The Xeon’s average benchmark score is 1264, and its nearest rivals include the Intel Core i3-1005G1 (average score 1265, delta -0.1%), AMD Athlon 200GE (1261, +0.3%), Intel Core i7-3615QM (1260, +0.3%), and Intel Core i3-7100T (1258, +0.5%). The Core i3-8109U’s average score is 1235, with nearest rivals including the Intel Pentium Gold G6600 (1235, 0%), Intel Xeon E3-1235L v5 (1232, +0.2%), Intel Core i7-3610QM (1244, -0.8%), and Intel Core i5-2500 (1220, +1.2%).

What the data shows is that the Xeon’s wins are broad and consistent across all Cinebench versions, while the Core i3’s win is isolated to one legacy test. The R15 single-core test appears to be an outlier, possibly due to the Xeon’s lack of a boost clock and the Core i3’s higher peak frequency. In every other test, the Xeon’s advantage is roughly one quarter, suggesting that the extra cores (4 vs 2) and larger caches provide a reliable performance buffer.
