Intel Xeon D-1540

The Intel Xeon D-1540 is a server-oriented processor built on the Broadwell architecture, featuring 8 cores and 16 threads. It operates with a base clock of 2000.00 MHz and a boost clock of 2.60 GHz, all within a 45 W TDP, and is designed for the Intel BGA 1667 socket with support for DDR3 and DDR4 memory.

Benchmark Performance

The benchmark data positions the Xeon D-1540 as a mid-range performer, holding a percentile rank of 51 among all CPUs. Its average benchmark score of 2467 places it in a tightly contested cluster, where minute differences separate it from its nearest rivals. In Cinebench R23, the processor achieves a multicore score of 8531, which is its most substantial result, while the single-core score of 1204 highlights a significant gap between parallel throughput and per-thread capability.

Comparing directly to its nearest rivals, the Xeon D-1540 leads the Intel Xeon W-2125 by a mere 0.1%, with an average score of 2467 against 2466. This effectively places the two processors at performance parity, despite their architectural differences. The margin against the Intel Xeon D-1541 is equally narrow, also at 0.1%, with the D-1540 scoring 2467 versus 2464. Against the Intel Core i7-1365UE, the lead expands slightly to 0.2%, and versus the Intel Core i5-8600, the D-1540 is 0.8% ahead. These deltas are within the noise of typical benchmarking variance, indicating that the Xeon D-1540 does not establish a meaningful performance advantage over any of these four rivals in aggregate scoring.

The Cinebench R20 results reinforce this picture. The multicore score of 3583 and single-core score of 505 show a ratio of roughly 7.1:1 between multi-threaded and single-threaded output, which is a clear indicator of the processor's design intent. In Cinebench R15, the multicore score of 859 and single-core score of 121 yield an even more pronounced ratio of approximately 7.1:1, confirming that the chip's strength lies entirely in scaling across its 8 cores and 16 threads rather than in raw clock speed or per-core efficiency.

Who Should Consider It

The Xeon D-1540 is best suited for workloads that can fully exploit its parallel architecture. Based on the benchmark results, the processor demonstrates strong multicore capability, particularly in threaded rendering and compute tasks. The Cinebench R23 multicore score of 8531 suggests that content creation applications such as video encoding, 3D rendering, and batch image processing, which scale across multiple cores, would benefit from the chip's 16 threads. Server workloads such as virtualization, database hosting, and web serving, which typically utilize multiple concurrent threads, are also a natural fit given the processor's Xeon branding and market segment designation of Server/Workstation.

However, the low single-core scores—121 in Cinebench R15, 505 in R20, and 1204 in R23—indicate that the processor is not well-suited for tasks that rely heavily on single-thread performance. Gaming, especially modern titles that favor high clock speeds, would underperform relative to desktop alternatives. Lightweight office productivity, web browsing, and document editing would also feel sluggish compared to processors with stronger single-core output, as these applications rarely utilize more than one or two threads effectively. The processor's 45 W TDP and support for ECC memory do, however, make it an attractive option for power-conscious server deployments where reliability and low heat output are prioritized over raw speed.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance defines the Xeon D-1540's character. The single-core score of 1204 in Cinebench R23 is modest, reflecting the 2.00 GHz base clock and 2.60 GHz boost clock, which are conservative for a server chip. This places the processor at a distinct disadvantage in scenarios where a single thread is the bottleneck, such as interactive applications, latency-sensitive queries, or legacy software that lacks multithreading support.

In contrast, the multicore scores tell a different story. The jump from 1204 single-core to 8531 multicore in R23 represents a 7.1x scaling factor across the 16 threads, which is close to ideal for a processor with 8 physical cores and hyper-threading. This indicates that the silicon is well-balanced for parallel execution, with the 1.5 MB L3 cache per core and dual-channel memory bus providing sufficient bandwidth to keep all cores fed during heavy compute loads. The 14 nm process node, with 3,200 million transistors on a 246 mm² die, enables this efficiency while maintaining the 45 W TDP.

Real-world implications are clear: the Xeon D-1540 excels in batch processing and sustained throughput, where the workload can be divided across all threads. It struggles in interactive or single-threaded environments, where the modest clock speeds and limited per-core performance become the limiting factor. Users should expect strong performance in render farms, CI/CD build servers, or file servers with many simultaneous connections, but should not expect snappy responsiveness in desktop-like usage patterns.

How It Compares

Intel Xeon W-2125: The W-2125 is essentially tied with the D-1540, with an average score of 2466 versus 2467, a 0.1% difference. Despite being a different product family, the aggregate performance is indistinguishable. The D-1540's advantage, if any, is negligible and would not be perceptible in real-world applications.

Intel Xeon D-1541: The D-1541, a close sibling in the same Xeon D series, scores 2464, trailing the D-1540 by 0.1%. This is a near-identical performance profile, suggesting that the D-1540 offers no tangible benefit over its direct relative. The two chips are effectively interchangeable from a benchmark perspective.

Intel Core i7-1365UE: The i7-1365UE, a modern mobile processor, scores 2463, placing it 0.2% behind the D-1540. This is a notably close result given the architectural generational gap, but the D-1540 edges out the competition on aggregate. The comparison highlights that the older server chip can still hold its own against a newer, lower-power part in overall throughput.

Intel Core i5-8600: The i5-8600, a desktop processor from the Coffee Lake generation, scores 2447, which is 0.8% lower than the D-1540. This is the largest delta among the nearest rivals, yet still a marginal gap. The D-1540's multicore advantage is enough to overcome the i5-8600's likely higher single-core speed, but the difference remains within a narrow band.
