Intel Core i3-10325 vs Intel Xeon W-2125 Comparison

FAQ

Q: Which processor has the higher boost clock?

A: The Intel Core i3-10325 boosts to 4.70 GHz, while the Intel Xeon W-2125 boosts to 4.50 GHz. The i3 also starts from a 3.90 GHz base clock compared to the Xeon's 4.00 GHz base.

Q: Do both CPUs support ECC memory?

A: No. The Intel Xeon W-2125 supports ECC memory, while the Intel Core i3-10325 does not. This is a key differentiator for workstation reliability use cases.

Q: Which processor has more PCIe lanes?

A: The Intel Xeon W-2125 provides 48 PCIe Gen 3 lanes from the CPU, whereas the Intel Core i3-10325 offers only 16 lanes. The Xeon is clearly built for expansion-heavy systems.

Q: How much L3 cache does each chip have?

A: The i3-10325 has 8 MB of shared L3 cache, while the Xeon W-2125 has 8.25 MB of shared L3 cache. The Xeon also has a larger L2 cache at 1 MB per core versus 256 KB per core on the i3.

Q: What is the market segment for each processor?

A: The Intel Core i3-10325 is a Desktop part in the Core 10th Gen series (Comet Lake), while the Intel Xeon W-2125 is a Server/Workstation part in the Xeon W family (Skylake-W). The Xeon is listed as end-of-life, whereas the i3 is still active.

Q: Which CPU has integrated graphics?

A: Only the Intel Core i3-10325 includes integrated graphics: Intel UHD Graphics 630. The Intel Xeon W-2125 has no integrated graphics, meaning it requires a discrete GPU for display output.

Architecture Differences

Both processors are built on Intel's 14 nm process node and share the same foundry, but they belong to different architectural families. The Intel Core i3-10325 uses the Comet Lake architecture, specifically the Comet Lake-R codename, and is part of the Core i3 generation for desktop platforms. The Intel Xeon W-2125, by contrast, uses the Skylake architecture with the Skylake-W codename, targeting server and workstation deployments.

The core configuration is identical in count and threading: both have 4 cores and 8 threads. Cache organization differs significantly. The i3-10325 has 64 KB of L1 per core and 256 KB of L2 per core, with 8 MB of shared L3. The Xeon W-2125 also has 64 KB of L1 per core, but its L2 jumps to 1 MB per core, and its shared L3 is slightly larger at 8.25 MB. This larger L2 cache on the Xeon suggests an architecture optimized for server-style workloads that reuse data in local caches.

Memory architecture marks another major split. The i3-10325 uses dual-channel DDR4 memory with a bandwidth of 42.7 GB/s. The Xeon W-2125 uses quad-channel DDR4 memory, doubling the theoretical bandwidth to 85.3 GB/s. This is a fundamental difference: the Xeon's memory subsystem is designed to feed more demanding workstation tasks, while the i3's dual-channel setup is typical of mainstream desktop parts.

PCIe connectivity also separates the two. The i3-10325 exposes 16 PCIe Gen 3 lanes from the CPU, which is standard for a desktop processor. The Xeon W-2125 provides 48 PCIe Gen 3 lanes, enabling multiple GPUs, NVMe drives, or other high-bandwidth cards. The Xeon also supports ECC memory, while the i3 does not, reinforcing the workstation positioning of the Xeon.

The sockets are incompatible: the i3-10325 fits Intel Socket 1200, while the Xeon W-2125 uses Intel Socket 2066. The Xeon's die size is recorded at 484 mm², whereas no die size is listed for the i3-10325. Thermal design power differs substantially as well, with the i3 rated at 65 W and the Xeon at 120 W. Neither processor has an unlocked multiplier, so overclocking is not an option on either platform.

Head-to-Head Benchmarks

The benchmark data shows a consistent pattern: the Intel Core i3-10325 wins every single Cinebench comparison, but the margins are narrow. Across all six recorded head-to-head tests, the i3 leads by 3.3% to 3.5%. There is no test where the Xeon W-2125 comes out ahead.

In Cinebench R15 multicore, the i3-10325 scores 881 against the Xeon's 852, a 3.4% advantage. The single-core R15 result is 124 versus 120, a 3.3% lead. Moving to Cinebench R20, the multicore score is 3673 for the i3 and 3551 for the Xeon, again a 3.4% gap. The R20 single-core test shows 518 versus 501, also 3.4%. In Cinebench R23 multicore, the i3 scores 8747 and the Xeon scores 8455, a 3.5% difference, the largest margin in the set. The R23 single-core result is 1234 against 1193, a 3.4% lead.

These results indicate that the i3-10325 holds a small but consistent edge in both multithreaded and single-threaded rendering workloads. The advantage is uniform across all three Cinebench generations, which suggests it is not a quirk of one benchmark version but a real performance characteristic. The Xeon's larger caches and quad-channel memory do not translate into a win here, likely because Cinebench does not heavily stress memory bandwidth or cache capacity at this core count.

It is notably the Xeon W-2125 has additional Geekbench results in the database: a multicore score of 4988 and a single-core score of 1323. The i3-10325 does not have corresponding Geekbench entries in the recorded data, so no direct comparison can be made on that test.

Where Each One Wins

The Intel Core i3-10325 wins in raw CPU benchmark performance. It leads in all six Cinebench head-to-head tests, covering both single-core and multicore workloads across R15, R20, and R23. The margins are consistent at roughly 3.3% to 3.5%, so for rendering tasks measured by Cinebench, the i3 is the faster processor. It also has integrated graphics, a lower TDP of 65 W, a higher boost clock of 4.70 GHz, and a lower launch MSRP of $154. It is an active product, while the Xeon is end-of-life.

The Intel Xeon W-2125 wins in platform capability rather than raw benchmark scores. Its quad-channel memory bus delivers 85.3 GB/s of bandwidth, exactly double the i3's 42.7 GB/s. It supports ECC memory, which matters for error-sensitive workstation applications. It offers 48 PCIe Gen 3 lanes, three times the i3's 16 lanes, enabling far more expansion options. Its L2 cache is 1 MB per core, four times the i3's 256 KB per core, and its L3 cache is slightly larger at 8.25 MB. The Xeon also has a higher base clock of 4.00 GHz, though its boost clock is lower at 4.50 GHz. It targets the Server/Workstation segment, whereas the i3 targets Desktop.

In the database's percentile ranking, both processors sit at the 49th percentile among all CPUs, meaning they are statistically equivalent in overall standing. The i3's average benchmark score is 2530, while the Xeon's is 2623. The Xeon's nearest rivals include the Intel Core i7-1195G7 at 2638 (0.6% higher), the Intel Core i9-8950HK at 2641 (0.7% higher), the Intel Core i7-5820K at 2642 (0.7% higher), and the Intel Core i7-8850H at 2604 (0.7% lower). The i3's nearest rivals are the Intel Xeon E-2244G at 2527 (0.1% higher), the Intel Xeon E5-1650 v3 at 2545 (0.6% lower), the Intel Xeon E-2144G at 2514 (0.7% higher), and the Intel Xeon E5-2643 v3 at 2511 (0.8% higher). These rival comparisons show both chips trading places with similar-class processors within a narrow band.

The Verdict

The data paints a clear picture: if raw Cinebench performance is the priority, the Intel Core i3-10325 is the better choice. It wins every head-to-head benchmark, holds a higher boost clock, draws less power, includes integrated graphics, and carries a lower launch MSRP of $154. Its 65 W TDP makes it far easier to cool and power than the Xeon's 120 W rating. For a desktop build focused on mainstream tasks and rendering workloads as measured by Cinebench, the i3-10325 is the stronger processor.

The Intel Xeon W-2125 is not without merit, but its advantages lie outside of the benchmark suite. Quad-channel memory at 85.3 GB/s, ECC support, and 48 PCIe lanes make it a more capable platform for workstation-class expansion and memory-sensitive tasks. The larger L2 cache and slightly larger L3 cache could benefit workloads with high cache locality, though the recorded Cinebench results do not reflect such an advantage. Its launch MSRP is $444, and it is end-of-life, which limits its appeal for new builds.

The realistic choice depends on the platform. A buyer building on Socket 1200 with a need for integrated graphics and lower power draw should pick the i3-10325. A buyer building on Socket 2066 with a need for ECC memory, massive PCIe expansion, and quad-channel bandwidth should pick the Xeon W-2125, accepting its lower benchmark scores and higher power consumption. Since both processors sit at the 49th percentile and produce nearly identical average scores, the decision hinges on platform features, not CPU speed. The i3 is the faster chip in the recorded tests; the Xeon is the more expandable one.
