Intel Core i9-10900X vs Intel Xeon W-2170B Comparison

Head-to-Head Benchmarks

The recorded benchmark data presents a remarkably consistent picture: the Intel Xeon W-2170B wins every single head-to-head comparison in the Cinebench suite, with the exact same delta of 9.2% in five of the six tests. The only deviation is the Cinebench R15 single-core test, where the Xeon leads by 9.3%. This uniformity across different rendering workloads suggests the advantage is structural rather than workload-specific.

Starting with multi-core results, the Xeon W-2170B scores 2085 in Cinebench R15 multi-core against 1910 for the Core i9-10900X. That is a 9.2% gap. In Cinebench R20 multi-core, the Xeon posts 8691 versus 7961, again a 9.2% lead. The gap persists in Cinebench R23 multi-core, where the Xeon reaches 20693 and the i9-10900X manages 18957, once more a 9.2% difference. These results indicate that the Xeon's additional cores and threads translate directly into sustained multi-threaded performance gains across all three generations of the Cinebench renderer.

Single-core results tell the same story, though with slightly less numerical distance. In Cinebench R15 single-core, the Xeon W-2170B scores 294 against 269 for the i9-10900X, a 9.3% advantage. In Cinebench R20 single-core, the Xeon leads 1226 to 1123, a 9.2% gap. The Cinebench R23 single-core test shows 2921 versus 2676, again a 9.2% delta. It is notable that the i9-10900X has a higher base clock (3.70 GHz versus 2.50 GHz) and a higher boost clock (4.70 GHz versus 4.30 GHz), yet it still loses every single-core test. This suggests that the Xeon's architecture, despite lower clocks, delivers superior instructions per clock in these workloads.

The average benchmark score in the database further contextualizes the gap. The Xeon W-2170B has an average benchmark score of 5985, while the Core i9-10900X sits at 5555. That is a difference of 430 points, roughly 7.7% lower for the i9. Interestingly, the i9-10900X's nearest rivals include the Intel Celeron G6900 (delta -0.1%), Intel Core i9-11900KB (-0.6%), Intel Atom x7433RE (-0.8%), and Intel Core i7-12700T (-0.9%). This indicates that the i9-10900X sits in a tightly packed cluster of CPUs with similar average scores, whereas the Xeon W-2170B has rivals like the Intel Core i9-9920X (+1.1%), AMD EPYC 7451 (+1.2%), AMD EPYC 7501 (-2.3%), and Intel Core i9-7940X (-2.6%). The Xeon's nearest rivals are all higher-end workstation or server parts, reflecting its positioning.

Where Each One Wins

Based on the benchmark data, the Intel Xeon W-2170B wins in every measured category, which makes the use-case split straightforward. The Xeon's advantages are not confined to multi-threaded rendering; it also wins all three single-core tests. Therefore, for any workload that relies on Cinebench-style rendering, whether single-threaded or multi-threaded, the Xeon W-2170B is the stronger choice.

The Core i9-10900X does have one measurable advantage that appears in the database: it supports Geekbench tests, while the Xeon W-2170B does not have any Geekbench scores recorded. The i9-10900X scores 10104 in Geekbench multi-core and 1438 in Geekbench single-core. However, since there are no comparable Geekbench numbers for the Xeon, this cannot be used to declare a head-to-head win. The database records zero wins for the i9-10900X in the head-to-head comparisons.

From a use-case perspective, the Xeon W-2170B is clearly positioned for server and workstation workloads. Its market segment is listed as Server/Workstation, it supports ECC memory, and it has 48 PCIe Gen 3 lanes. The i9-10900X, by contrast, is a desktop part with no ECC support and unspecified PCIe lane count (simply listed as Gen 3). For compute tasks that benefit from more cores (14 versus 10) and more threads (28 versus 20), the Xeon is the appropriate choice. The i9-10900X does have a higher base clock and boost clock, which might be relevant for lightly threaded tasks that are not represented in the available benchmark suite, but the recorded data shows the Xeon winning even the single-core tests.

The production status also differentiates them: the Xeon W-2170B is end-of-life, while the Core i9-10900X is active. This matters for system longevity and availability, though it does not change the performance picture. The i9-10900X also has an unlocked multiplier, whereas the Xeon is locked, which means the i9 offers manual overclocking headroom that the Xeon does not. Overclocking could potentially close the single-core gap, but the database does not include any overclocked results.

Architecture Differences

The two processors share several fundamental traits but differ in key architectural details. Both are built on Intel's 14 nm process node and use the Intel Socket 2066. The Xeon W-2170B is based on the Skylake architecture (codename Skylake-W), while the Core i9-10900X uses the Cascade Lake architecture (codename Cascade Lake-X). Both are from Intel, and both have the same L1 cache (64 KB per core) and L2 cache (1 MB per core). The L3 cache is also identical at 19.25 MB shared.

The core counts differ significantly: the Xeon has 14 cores and 28 threads, while the i9-10900X has 10 cores and 20 threads. This is the primary reason for the multi-core performance gap. The Xeon also has a larger die size at 484 mm², whereas the i9-10900X's die size is not recorded. The Xeon's base clock is 2.50 GHz, and its boost clock is 4.30 GHz. The i9-10900X runs at a 3.70 GHz base clock and a 4.70 GHz boost clock. Despite the higher clocks on the i9, the Xeon wins all single-core tests, indicating that the Skylake architecture delivers higher IPC than Cascade Lake in these specific workloads.

Memory support is another differentiator. Both support DDR4 and use a quad-channel memory bus. The Xeon W-2170B has a recorded memory bandwidth of 85.3 GB/s, while the i9-10900X's memory bandwidth is not listed. ECC memory is supported on the Xeon but not on the i9. The Xeon also has 48 PCIe Gen 3 lanes (CPU only), while the i9's PCIe configuration is simply listed as Gen 3 without a lane count.

The market segments are distinct: the Xeon is a Server/Workstation part, while the i9 is a Desktop part. The Xeon's part number is SR3W3, and it was released on 2017-12-20. The i9-10900X was released later, on 2019-10-18, and has no recorded part number. The Xeon's generation is listed as "Xeon W (Skylake-W)", while the i9's generation is "Core i9 (X-Series 10th Gen)". The Xeon is end-of-life, whereas the i9 is active. The multiplier is locked on the Xeon and unlocked on the i9.
