Intel Xeon E-2286M

The Intel Xeon E-2286M is an end-of-life, server-class mobile processor built on the Coffee Lake-H architecture. It is a 14 nm part fabricated by Intel, occupying a die size of 180 mm². The processor is positioned for mobile workstations, with a launch MSRP of $623, and carries the part number SRFCZ. Its benchmark results place it at the 59th percentile of all CPUs tested, with an average benchmark score of 3838, indicating a solid mid-range performer in its generation.

Platform and Compatibility

The E-2286M uses the Intel BGA 1440 socket, which is a soldered, non-upgradeable interface designed for laptops and mobile workstations. This means the processor is permanently attached to the motherboard, and any future upgrade requires replacing the entire system rather than swapping the CPU. The platform supports DDR4 memory through a dual-channel memory bus, providing a maximum memory bandwidth of 42.7 GB/s. Error-correcting code (ECC) memory is supported, a notable feature for workstation reliability that distinguishes it from many consumer mobile chips. PCIe connectivity is provided through Generation 3, with 16 lanes available from the CPU itself. Integrated graphics are handled by the UHD Graphics P630, which is sufficient for basic display output but not for intensive graphical workloads. The processor is marked as end-of-life, and its release date was May 28, 2019, meaning it belongs to an older platform generation with no forward upgrade path within its socket.

Single-Thread vs Multi-Thread Behavior

The E-2286M has 8 cores and 16 threads, with a base clock of 2.40 GHz and a boost clock of 5.00 GHz. This combination of a high boost clock and a moderate core count creates a distinct performance profile. In Cinebench R23, the single-core score is 1824, while the multi-core score reaches 12921. The ratio between these scores shows that scaling from one core to all cores yields roughly a 7.1x improvement, which is below the theoretical 8x maximum due to thermal and power constraints. This indicates that the processor can push individual cores very high for lightly threaded tasks, but the multi-core performance is slightly limited by the 45 W TDP envelope. In Geekbench, the single-core score of 1537 and multi-core score of 6746 follow a similar pattern, with multi-core being about 4.4x higher than single-core. For real workloads, this means applications that rely on high clock speeds for single-threaded responsiveness, such as legacy software or certain database queries, will perform strongly. Conversely, heavily threaded workloads like video rendering or scientific simulations will see good but not exceptional scaling, with the processor leveraging its 16 threads effectively within its power budget.

Power and Thermals

The E-2286M is rated at a 45 W TDP, which places it in the standard mobile performance class for high-end laptops and workstations. This TDP level is moderate, allowing for the high 5.00 GHz boost clock without requiring an extreme cooling solution. The data indicates that a capable air cooler, typical of larger mobile workstations, should be sufficient to sustain boost clocks under load. The 14 nm process node, while older than modern nodes, is well understood and generally produces predictable thermal behavior. The 45 W rating suggests that the processor is designed for sustained performance in a chassis with adequate ventilation, rather than for ultra-thin or passively cooled designs. The integrated UHD Graphics P630 adds to the thermal load, but its contribution is minimal for a processor of this class. Based on the benchmark scores, particularly the Cinebench R23 multi-core result of 12921, the processor appears to maintain its performance over time without excessive thermal throttling, as the multi-core scores are consistent with what would be expected from an 8-core, 45 W part.

How It Compares

Against the Intel Core i5-11260H, the E-2286M is essentially identical in average benchmark score, with both achieving 3838. The delta is 0%, meaning the two processors are performance peers in aggregate, despite their architectural differences.

The AMD Ryzen 7 2700 is a close rival, with the E-2286M trailing by 0.3% in average score. The Ryzen 7 2700 scores 3849 versus the E-2286M's 3838, making the difference negligible in real-world terms.

The AMD Ryzen 7 1800X scores 3858, which is 0.5% higher than the E-2286M. This places the Xeon slightly behind this older AMD flagship, but the margin is within run-to-run variance for most benchmarks.

The AMD Ryzen 5 5560U trails the E-2286M by 0.8%, scoring 3808. The E-2286M holds a small but consistent lead over this rival, showing that it remains competitive against newer mobile parts.

Benchmark Performance

In Cinebench R15, the E-2286M scores 1302 in multi-core and 183 in single-core. The single-core score of 183 is modest, reflecting the high boost clock but also the older architecture. The multi-core score of 1302 shows that the 8-core configuration scales well, but it is not a top-tier result. Moving to Cinebench R20, the multi-core score rises to 5426, while single-core is 766. This represents a significant improvement over R15 due to the workload differences between the test versions. In Cinebench R23, the multi-core score is 12921 and single-core is 1824. The ratio of R23 multi-core to R20 multi-core is roughly 2.38x, which is consistent with the expected scaling of the newer benchmark version. Geekbench results show a multi-core score of 6746 and a single-core score of 1537. The Geekbench multi-core score is lower relative to Cinebench R23 multi-core, indicating that the processor's performance varies by workload type. Compared to its rivals, the E-2286M matches the Intel Core i5-11260H exactly in average score, with a 0% delta. It is 0.3% behind the AMD Ryzen 7 2700, 0.5% behind the AMD Ryzen 7 1800X, and 0.8% ahead of the AMD Ryzen 5 5560U. These deltas are all within 1%, meaning that across the entire benchmark suite, the E-2286M is functionally equivalent to its nearest competitors. The 59th percentile rank confirms that it sits in the middle of the performance distribution, neither a high-end part nor a low-end one.

Who Should Consider It

The E-2286M is best suited for professionals who need a mobile workstation with reliable multi-threaded performance and ECC memory support. The 8 cores and 16 threads, combined with a 5.00 GHz boost clock, make it a strong choice for tasks like software compilation, data analysis, and moderate 3D rendering, where the Cinebench R23 multi-core score of 12921 indicates competent throughput. The single-core performance, with a Geekbench score of 1537, is adequate for office productivity and general application responsiveness, though it is not exceptional by modern standards. For gaming, the processor's performance is adequate but not ideal, as the 16 PCIe Gen 3 lanes and integrated UHD Graphics P630 are not designed for high-end discrete GPU workloads; however, with a dedicated GPU, the CPU would not be a bottleneck in most titles. The ECC memory support is a key differentiator for users who require data integrity in financial, scientific, or server-like applications. Given its end-of-life status and 45 W TDP, it is most appropriate for users who are purchasing a used or refurbished mobile workstation and prioritize stability and multi-core capability over the latest features. The close performance parity with the AMD Ryzen 7 2700 and Ryzen 7 1800X means that users coming from those desktop platforms will find similar performance in a mobile form factor, with the added benefit of portability. Conversely, users who need the absolute highest single-thread performance or the most modern instruction sets should look to newer processors, as the E-2286M's single-core scores lag behind more recent mobile chips.
