Intel Xeon D-1571

The Intel Xeon D-1571 is a server/workstation processor listed with 16 cores and 32 threads. Manufactured by Intel on a 14 nm process, it belongs to the Xeon D (Broadwell-DE) generation and uses the Broadwell architecture. The record specifies a base clock of 1.30 GHz, a boost clock of 2.10 GHz, and a TDP of 45 W. Its socket is Intel BGA 1667, and its market segment is Server/Workstation. The database entry contains no benchmark scores, no nearestRivals entries, and no deltaPct values; the avgBenchmarkScore is 0 and the percentileVsAllCpus value is 50. Those missing fields shape the analysis below.

How It Compares

Because the nearestRivals array is empty, there are no named rivals to describe and no one-paragraph-per-rival comparison can be written. The fact pack supplies no competitor names, no rival scores, and no deltaPct values for any other processor. The only comparative metric present is percentileVsAllCpus, set to 50. If a benchmark score existed, a 50th percentile would put the D-1571 at the midpoint of all CPUs in the database; however, the benchmarks array is empty, so the percentile is not attached to a measured result. In addition, avgBenchmarkScore is 0, which is consistent with an entry that has no recorded benchmark data. The empty nearestRivals array means that exact percentage advantages or deficits relative to competing parts cannot be computed from this record. A missing nearestRivals entry is a structural fact: the database has not assigned this SKU a set of comparison points. Without comparison points, the 50th percentile cannot be validated, and the fact pack does not provide any method for deriving a ranking from it. The D-1571 therefore lacks the normal competitive positioning data that a benchmark database usually provides.

Power and Thermals

The listed TDP is 45 W. That is the only power figure in the fact pack, and no cooling solution is specified. For a 16-core, 32-thread processor, 45 W is a modest power envelope, and the 1.30 GHz base clock reflects a design that prioritizes energy efficiency in dense server or workstation installations. The boost clock of 2.10 GHz is the highest frequency in the record, but the fact pack does not state how long that boost can be sustained or whether all cores can reach it simultaneously. The 14 nm process node is the only manufacturing detail relevant to power behavior in this record; the fact pack does not include a maximum operating temperature or thermal design guidance. The record also does not specify a case power draw or a recommended cooler. Thus, while the TDP is 45 W, the actual thermal solution depends on system design, which is not documented. The 45 W TDP sits alongside 16 cores and 32 threads; that ratio of cores to power budget suggests the silicon is intended for platforms with limited cooling space. The absence of a cooler specification means the cooling tier can be characterized only qualitatively: 45 W generally suggests a capable low-profile or compact cooling solution, but the database does not name a required cooler class.

Single-Thread vs Multi-Thread Behavior

This record contains no single-thread or multi-thread benchmark scores. Without those fields, the behavior split must be inferred from the listed core and clock structure. The D-1571 has 16 cores and 32 threads, a base clock of 1.30 GHz, and a boost clock of 2.10 GHz. The core count is high, while the base clock is low; the boost clock marks the upper frequency bound. This pattern is typical of processors designed for throughput-oriented workloads: many threads are available, but each thread does not necessarily run at a high clock speed. The cache hierarchy is specified as 64 KB of L1 per core, 256 KB of L2 per core, and 1.5 MB of L3 per core; these caches are the per-core resources that can affect latency-sensitive code, although no benchmark data verifies their impact. There is no total L3 value in the fact pack, and the vCache3d field is null. The fact pack lists no per-core cache sharing details beyond per-core amounts, so the effective latency and capacity characteristics for single-threaded execution cannot be fully reconstructed from this record. For single-thread-bound work, the relevant figure is the 2.10 GHz boost clock, but the database provides no per-core frequency measurement or single-thread score. For multi-thread-bound work, the 32-thread count is the relevant resource, but no scaling efficiency or parallel benchmark score is recorded. Thus the data supports a qualitative conclusion — parallel throughput is the design intent — while supplying no quantitative validation.

Who Should Consider It

The market segment field is Server/Workstation, so that segment is the stated intended audience. The record provides no benchmark scores for gaming, content creation, or office productivity, so no measured ranking for those workloads can be given. The D-1571's relevant attributes for server or workstation deployment are its 16 cores, 32 threads, ECC memory support, dual-channel DDR3/DDR4 memory support, and PCIe Gen 3 with 24 CPU-attached lanes. ECC memory support is particularly relevant to systems where data integrity matters, although the fact pack does not quantify reliability. The dual-channel memory bus and the absent memory bandwidth field mean that memory-bound workload behavior cannot be benchmarked from this entry. The PCIe lane count is 24; that number indicates how many PCIe devices can be attached at Gen 3 speeds, but the fact pack does not state how the lanes are arranged. The processor is not equipped with an integrated graphics unit; the integratedGraphics field is null, which is typical for a server/workstation part but means a discrete GPU is required for display output. The multiplier is not unlocked, so user-controlled overclocking is not indicated. Because no measured scores exist, a recommendation must be conditional: if the use case is a server or workstation workload that can use many threads and needs ECC memory, the listed specifications are relevant; if the use case is client gaming or mainstream office work, no benchmark evidence in this record supports a specific recommendation.

Benchmark Performance

The benchmarks array is empty, and the nearestRivals array is empty. There are therefore no exact percentage deltas to report and no rival scores to compare. The avgBenchmarkScore is 0; in a record with no benchmark entries, this value should be read as the absence of aggregate measurement, not as a result. The percentileVsAllCpus value is 50, which would indicate a median position in the database's CPU ranking if it were supported by a score; no such score is present. No single-thread result, no multi-thread result, no per-application result, and no deltaPct value exists for the D-1571. No benchmark table is present, no composite score is present, and no workload-specific score is present. The only numeric benchmark-like values are 0 and 50, both of which are tied to an empty benchmark set. Consequently, there is no quantitative evidence to rank this processor against any other CPU. Any percentage comparison written from this page would be unsupported by the fact pack. The lack of benchmark data is the most significant obstacle to using this record for performance analysis.

Platform and Compatibility

The D-1571 uses the Intel BGA 1667 socket. The part number is SR2M0. The generation identifier is Xeon D (Broadwell-DE), and both architecture and codename are listed as Broadwell. Intel is listed as the foundry, and the process node is 14 nm. The die integrates 3,200 million transistors on a 246 mm² die. Memory support covers DDR3 and DDR4, with a dual-channel bus and ECC support. The memory bandwidth field is null, so no bandwidth number can be cited. The PCIe interface is specified as Gen 3 with 24 lanes, and the fact pack marks these as CPU-only lanes. The integratedGraphics field is null, and the multiplier is not unlocked. The launch date is 2016-02-23, and the launch MSRP was 1249. The production status is Active. The series field is null, and no total L3 value is listed. The BGA socket type in the record suggests a board-mounted package; no alternative socket is listed, and no upgrade path is documented. The fact pack does not include a list of compatible chipsets, motherboard families, or alternative sockets; upgrade-path information is therefore absent from the record.
