Intel Xeon W-2140B

The Intel Xeon W-2140B is an 8-core, 16-thread server/workstation processor built on Intel's 14 nm Skylake-W architecture, with a base clock of 3.20 GHz and a boost clock of 4.20 GHz. It supports DDR4 memory over a quad-channel interface with 85.3 GB/s of bandwidth, includes ECC support, and offers 48 PCIe Gen 3 lanes from the CPU. Its benchmark results place it in the 61st percentile of all CPUs, with an average benchmark score of 4279 points, positioning it as a mid-pack performer among contemporary workstation chips.

Benchmark Performance

The W-2140B delivers a multi-core Cinebench R15 score of 1483 points and a single-core score of 209. In Cinebench R20, it reaches 6183 multi-core and 872 single-core, while in R23 it scores 14723 multi-core and 2078 single-core. Geekbench results show 7381 multi-core and 1299 single-core. These numbers indicate a processor that scales well across rendering and general compute workloads, though its single-thread scores are relatively modest for a 2017-era part.

Comparing its overall average score of 4279 against nearest rivals, the W-2140B sits nearly even with the AMD Ryzen 7 PRO 7730U (avg 4287), trailing by just 0.2%. It edges out the Intel Xeon E-2378 (avg 4261) by 0.4% and the Intel Xeon E-2278G (avg 4251) by 0.7%. The largest gap is against the Intel Core i5-12500T (avg 4235), where the W-2140B leads by 1.0%. These deltas are small, meaning the W-2140B is effectively performance-equivalent to its closest competitors in aggregate benchmarks, despite differences in architecture and generation.

The multi-core scores show a stronger story. In Cinebench R23 multi-core, the W-2140B's 14723 points represent a substantial throughput advantage over typical 8-core parts from the same era, but the single-core R23 score of 2078 is less impressive, indicating that the Skylake-W core design prioritizes sustained multi-threaded workloads over peak single-thread responsiveness. The Geekbench multi-core score of 7381 reinforces this pattern, while the single-core 1299 lags behind modern low-power parts.

Power and Thermals

The W-2140B has a TDP of 120 W, which classifies it as a mid-range workstation processor. This TDP level implies that a capable air cooler or a modest liquid cooler is sufficient for sustained operation, as the 14 nm process node and 484 mm² die size generate significant heat under load. The 120 W TDP is typical for 8-core Skylake-X derivatives, allowing for all-core boost frequencies near the 4.20 GHz ceiling, but thermal throttling can occur if cooling is inadequate.

Given the 120 W TDP, the processor does not require exotic cooling solutions. Standard tower coolers with multiple heat pipes or 120 mm fans will handle it, and many workstation chassis with front-to-rear airflow will keep temperatures within spec. The quad-channel memory controller and 48 PCIe lanes also contribute to power draw, but the CPU package itself remains within the 120 W envelope. For server environments, this TDP allows for dense configurations, though the lack of an unlocked multiplier (multiplierUnlocked: false) prevents overclocking to push beyond the rated boost.

How It Compares

vs. AMD Ryzen 7 PRO 7730U: The W-2140B trails the Ryzen 7 PRO 7730U by 0.2% in average benchmark score (4279 vs. 4287). This is a negligible difference, but the Ryzen part is a mobile/low-power processor with a much lower TDP, so the W-2140B delivers comparable aggregate performance at a significantly higher power draw. In multi-core rendering, the W-2140B's Cinebench R23 score of 14723 would likely outpace the Ryzen's, though the Geekbench multi-core gap (7381 vs. the Ryzen's unspecified) is not directly available. The 0.2% delta suggests that for mixed workloads, users would see nearly identical performance.

vs. Intel Xeon E-2378: The W-2140B holds a 0.4% advantage over the Xeon E-2378 (4279 vs. 4261). The E-2378 is a newer 8-core Xeon with a different microarchitecture, but the W-2140B's Skylake-W design still edges it out in aggregate benchmarks. This indicates that the W-2140B's higher boost clock (4.20 GHz vs. unspecified) and memory bandwidth (85.3 GB/s) compensate for architectural differences. In single-threaded tasks, the W-2140B's R23 score of 2078 is competitive, though the E-2378 may have a slight edge in some workloads.

vs. Intel Xeon E-2278G: The W-2140B leads the E-2278G by 0.7% (4279 vs. 4251). The E-2278G is a higher-clocked Xeon with integrated graphics, but the W-2140B's larger L3 cache (11 MB shared) and quad-channel memory support likely contribute to its aggregate lead. The delta is small, so real-world differences would be within noise for most applications. For multi-threaded rendering, the W-2140B's Cinebench R20 score of 6183 is a solid indicator of its capability.

vs. Intel Core i5-12500T: The W-2140B outperforms the Core i5-12500T by 1.0% (4279 vs. 4235). The i5-12500T is a low-power desktop part with a 35 W TDP, so the W-2140B's 120 W envelope buys only a 1% average performance advantage. This highlights that for power-sensitive environments, the i5-12500T offers similar throughput at a fraction of the power, while the W-2140B's strengths lie in its ECC support, quad-channel memory, and 48 PCIe lanes, features not found on consumer parts.

Who Should Consider It

The W-2140B is best suited for workstation and server workloads that leverage multi-threaded processing and require platform features like ECC memory and quad-channel bandwidth. Its Cinebench R23 multi-core score of 14723 indicates strong performance in 3D rendering, video encoding, and scientific simulations. For single-threaded tasks such as office productivity or light web browsing, the 2078 R23 single-core score is adequate but not exceptional; users in those scenarios would find more efficient options.

Content creators working with 4K video or complex 3D scenes will benefit from the 8 cores and 16 threads, especially when combined with the 85.3 GB/s memory bandwidth for large datasets. The 48 PCIe lanes allow for multiple GPUs or high-speed NVMe storage arrays, making it a viable foundation for a render farm or a data analysis workstation. However, the 120 W TDP and lack of an unlocked multiplier mean that overclocking is not an option; users seeking higher per-core performance might consider newer architectures.

For office environments, the W-2140B is overkill. The single-core Geekbench score of 1299 is modest, and the processor's power draw is unnecessary for spreadsheet or word-processing tasks. Similarly, gamers would find better value in consumer chips with higher single-thread performance, as the W-2140B's strengths do not translate to frame-rate gains. The processor's end-of-life status (productionStatus: "End-of-life") also means that new system builders should weigh the availability of newer alternatives, though existing platforms can still deliver solid multi-threaded throughput.

Single-Thread vs Multi-Thread Behavior

The W-2140B exhibits a clear split between its single-thread and multi-thread performance. In Cinebench R23, the multi-core score of 14723 is roughly 7.1 times the single-core score of 2078, which is close to the theoretical scaling for 8 cores with 16 threads. This indicates excellent multi-threaded efficiency, with minimal overhead from thread synchronization. The Geekbench scores show a similar pattern: 7381 multi-core versus 1299 single-core, a ratio of 5.7, reflecting that the processor can harness most of its cores effectively in parallel workloads.

The single-core scores, however, are less impressive. A R23 single-core score of 2078 places it well below modern desktop parts, which often exceed 3000 points. This is due to the Skylake architecture's age and its moderate 4.20 GHz boost clock. For workloads that depend heavily on a single thread, such as legacy applications, some database queries, or user interface responsiveness, the W-2140B will feel slower than a newer 6-core or 8-core consumer chip. The 61st percentile ranking overall is dragged down by these single-thread results, despite the strong multi-core showing.

In practice, the W-2140B is a multi-threaded workhorse. Its 8 cores and 16 threads, combined with the 11 MB L3 cache and quad-channel memory, allow it to excel in rendering, compiling, and batch processing. The single-thread performance is sufficient for general use, but users who prioritize single-thread speed should look elsewhere. The benchmark data consistently shows that this processor rewards heavily parallelized tasks, making it a reasonable choice for server and workstation deployments where throughput is the primary metric.
