Xeon D-1518 Core Configuration
Processing cores and threading
The Intel Xeon D-1518 features 4 physical cores and 8 threads, which directly impacts multi-threaded performance in CPU benchmarks. More cores allow the processor to handle parallel workloads efficiently, improving performance in video editing, 3D rendering, and multitasking scenarios. Thread count determines how many simultaneous tasks the CPU can process, with higher thread counts benefiting productivity applications and content creation workflows.
D-1518 Clock Speeds
Base and boost frequencies
Clock speed is a critical factor in Xeon D-1518 benchmark performance, measured in GHz. The base clock represents the guaranteed operating frequency, while the boost clock indicates maximum single-core performance under optimal conditions. Higher clock speeds translate to faster single-threaded performance, which is essential for gaming and applications that don't fully utilize multiple cores. The Xeon D-1518 by Intel can dynamically adjust its frequency based on workload and thermal headroom.
Intel's Xeon D-1518 Cache Hierarchy
L1, L2, L3 cache sizes
Cache memory is ultra-fast storage built directly into the D-1518 processor die. L1 cache provides the fastest access for frequently used data, while L2 and L3 caches offer progressively larger storage with slightly higher latency. Larger cache sizes significantly improve CPU benchmark scores by reducing memory access times. The Xeon D-1518's cache configuration is optimized for both gaming performance and productivity workloads, minimizing data fetch delays during intensive computations.

About Intel Xeon D-1518
Intel Xeon D-1518 is a 4-core, 8-thread Broadwell-DE server/workstation processor using the Intel BGA 1667 socket interface. It has a 2.20 GHz base clock with no listed boost clock and a 35 W TDP. Its average benchmark score is 1121, and it ranks at the 32nd percentile among all CPUs in the database. This is a compact, low-power Xeon part aimed at embedded and server use rather than high-frequency desktop performance.
Benchmark Performance
The Cinebench results show a modest but consistent throughput profile. In Cinebench R15, the D-1518 scores 390 multi-core and 54 single-core. In R20, those figures are 1628 and 229, respectively. In R23, the multi-core score is 3877, while the single-core score is 547. The average benchmark score of 1121 places it alongside desktop and entry Xeon parts. At the 32nd percentile, most tested CPUs in the database rank above it.
The nearest rivals are tightly clustered. The AMD Athlon 240GE has an average score of 1121 with a deltaPct of 0, so the D-1518 is an exact aggregate match. The Intel Pentium Gold G5600 has an average score of 1123 and a deltaPct of -0.2, meaning the D-1518 trails that chip by 0.2%. The Intel Pentium Gold G5500 and the Intel Xeon E5-2603 v3 both average 1117 with a deltaPct of 0.3, meaning the D-1518 is 0.3% ahead of each. These are very small differences; the D-1518 does not move the needle dramatically within its own peer group. Its position is defined less by raw score and more by platform attributes.
Power and Thermals
The D-1518 is rated at a 35 W TDP, which is a low-power envelope for a Xeon-branded part. It is built on Intel's 14 nm process, with 3,200 million transistors on a 246 mm² die. The absence of a boost clock means operation is pinned to the 2.20 GHz base clock, keeping the power profile flat. Cooling requirements are therefore minimal. The data suggests a modest heatsink or small chassis airflow arrangement is enough; dense embedded systems are the natural environment for this chip. Low TDP also matters for systems that need to run 24/7 in constrained enclosures.
Single-Thread vs Multi-Thread Behavior
The single-thread and multi-thread scores diverge sharply. In Cinebench R15, the multi-core score of 390 is much larger than the 54 single-core result. R20 shows the same pattern: 1628 multi-core versus 229 single-core. R23 continues it: 3877 multi-core versus 547 single-core. These gaps are consistent with a 4-core, 8-thread design. The multi-thread results show that throughput scales well when all logical processors can be used. The single-thread results are conservative, as expected from a 2.20 GHz part with no boost clock. Real workloads that spread across threads, such as small virtualization hosts, build servers, or database lookups, will extract far more performance than single-threaded tasks. Applications that need top per-core speed will find the D-1518 limiting.
How It Compares
AMD Athlon 240GE — The Athlon 240GE has an average score of 1121, exactly matching the D-1518, with a deltaPct of 0. The two are therefore performance peers in aggregate benchmarks. The D-1518 counters that tie with ECC memory support, 24 PCIe Gen 3 lanes, and a server-oriented feature set.
Intel Pentium Gold G5600 — The G5600 averages 1123, which is 0.2% higher than the D-1518. This is a negligible lead. A buyer choosing between them would be deciding on platform characteristics, not on benchmark throughput.
Intel Pentium Gold G5500 — The D-1518 averages 1121 against 1117 for the G5500, a deltaPct of 0.3 in favor of the Xeon. The 4-point gap is within run-to-run noise in most benchmark situations. The D-1518's advantage is the Xeon feature set, not a meaningful speed difference.
Intel Xeon E5-2603 v3 — The E5-2603 v3 also posts an average score of 1117, and the D-1518 is 0.3% ahead. Both are Xeon-branded, but the D-1518 brings the same aggregate score in a 35 W TDP class and BGA package. In aggregate performance, the two are effectively tied.

Platform and Compatibility
The D-1518 uses the Intel BGA 1667 socket interface, which is a BGA package rather than a socketed desktop processor. It belongs to the Broadwell architecture, specifically the Xeon D (Broadwell-DE) generation. The memory controller supports DDR3 and DDR4 in a dual-channel configuration, with ECC memory support. PCIe connectivity is Gen 3 with 24 lanes from the CPU. The cache hierarchy is 64 KB of L1 per core, 256 KB of L2 per core, and 1.5 MB of L3 per core. The part number is SR2DN. Because the package is BGA, the processor is mounted to the board; an upgrade path means changing the platform rather than swapping the CPU. The production status is Active, so the part remains listed as available.
Who Should Consider It
This processor is suited for Server/Workstation applications where low power and compact integration matter more than top-end performance. The 35 W TDP, 4-core/8-thread design, ECC memory support, and 24 PCIe Gen 3 lanes make it a fit for embedded servers, network appliances, storage controllers, and small virtualization systems. Multi-threaded workloads will benefit from the R23 multi-core score of 3877 and the earlier multi-core results. Single-thread-intensive workloads will be held back by the R23 single-core score of 547 and the lack of an unlocked multiplier. Office productivity that does not rely on peak per-core speed is within reach, but this is not a gaming- or high-frequency-desktop-oriented part, especially because no integrated graphics is listed. It should be considered by those who need Xeon platform features in a low-power, embedded form factor.
