Intel Xeon E-2336

The Intel Xeon E-2336 is a 6-core, 12-thread server and workstation processor built on the Rocket Lake-E architecture and the 14 nm process node. It targets the entry-level server market, offering a base clock of 2.90 GHz and a boost clock of 4.80 GHz, with a shared 12 MB L3 cache and 80 KB of L1 and 512 KB of L2 cache per core. The chip posts an average benchmark score of 3985, placing it at the 60th percentile of all CPUs in the database, which signals a solid mid-pack performer for its segment rather than a top-tier part.

Platform and Compatibility

The Xeon E-2336 uses the Intel Socket 1200 platform, making it compatible with motherboards designed for that socket, which is shared with the consumer Rocket Lake desktop lineup. This socket provides a notable upgrade path within the same platform generation, though the E-2336 sits at the upper end of the Xeon E family for that socket. The processor supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s. ECC memory is supported, which is a critical feature for server and workstation reliability, distinguishing it from many consumer desktop chips that lack this capability.

For expansion, the CPU provides 20 PCIe Gen 4 lanes directly from the processor. This PCIe implementation supports modern high-bandwidth devices such as NVMe storage and discrete GPUs, though the lane count is modest compared to higher-tier workstation platforms. The chip is fabricated by Intel on a 14 nm process with a die size of 276 mm². The production status is listed as Active, and the part number is SRKN5.

Memory support is limited to DDR4, with no DDR5 compatibility, which aligns with the platform's release era. The dual-channel memory bus means that memory-intensive workloads like large database operations or virtualized environments will benefit from populating both channels with matched modules. The combination of ECC support and the Socket 1200 form factor makes this a drop-in option for existing server boards that already use the platform, though the 20 PCIe lanes require careful allocation for multi-device configurations.

Power and Thermals

The Xeon E-2336 has a TDP of 65 watts, which classifies it as a low-power part relative to many workstation CPUs. This TDP level implies that a capable air cooler is sufficient for most deployments, and it allows for use in compact chassis or densely packed server racks where thermal headroom is limited. The 65-watt class also means that power delivery requirements on the motherboard are modest, potentially enabling lower-cost boards that are not designed for high-core-count or high-clock parts.

The thermal profile is further aided by the 14 nm process node, which is not the most efficient by modern standards, but the moderate core count and clock speeds keep heat output manageable. The boost clock of 4.80 GHz does require adequate cooling during sustained single-threaded loads, but the 6-core design spreads the thermal load across the die. For system integrators, the 65-watt TDP simplifies cooling design, as it does not mandate large radiators or high-static-pressure fans. The low power envelope also makes the E-2336 a candidate for passive-cooled or low-noise builds, provided the chassis has adequate airflow.

Benchmark Performance

Benchmark results show a processor that balances single-threaded agility with reasonable multi-threaded throughput. In Cinebench R23, the E-2336 scores 13780 in multi-core and 1945 in single-core. The single-core score of 1945 indicates strong per-thread performance, which is beneficial for lightly threaded tasks. The multi-core score of 13780 reflects the 6-core, 12-thread configuration, and it places the chip below many 8-core consumer parts but above typical 4-core office CPUs.

Cinebench R20 results are consistent, with a multi-core score of 5787 and a single-core score of 816. The R15 scores of 1388 multi-core and 195 single-core follow the same pattern. Across these tests, the single-core performance is a standout feature, with the 4.80 GHz boost clock delivering results that rival or exceed many newer consumer processors in per-thread tasks. The multi-core performance is adequate for entry-level server workloads but is not exceptional, as the 6-core count limits parallel throughput.

The average benchmark score of 3985 places the E-2336 at the 60th percentile of all CPUs, indicating that it outperforms a majority of processors in the database but trails the top quartile significantly. The nearest rival, the Intel Xeon D-2733NT, has an average score of 3984, a delta of 0%, meaning the two chips are statistically identical in overall performance. The AMD Ryzen Threadripper 1900X scores 3995, which is 0.2% higher, while the Intel Core i9-13900TE scores 3998, 0.3% higher. The AMD Ryzen 7 PRO 5875U scores 3971, 0.4% lower. These deltas are all within noise, indicating that the E-2336 is functionally equivalent to its closest competitors in aggregate performance.

Who Should Consider It

The E-2336 is suited for workloads that prioritize single-threaded performance and require ECC memory support. For small business servers running database applications, the high boost clock of 4.80 GHz can accelerate query processing, while ECC memory protects against data corruption. The 6-core, 12-thread configuration is adequate for virtualization with a modest number of VMs, though heavily virtualized environments with many concurrent tenants would benefit from more cores.

For workstation tasks like software compilation or 3D modeling, the single-core performance in Cinebench R23 (1945) helps with operations that are not fully parallelized, such as code serialization or UI responsiveness. The multi-core score of 13780 in Cinebench R23 is sufficient for light rendering or batch processing, but users who regularly run multi-hour render jobs should look to higher-core-count alternatives. Office productivity is not a primary use case, but the chip's strong single-threaded scores ensure snappy performance in spreadsheet, document, and web-based applications.

The 20 PCIe Gen 4 lanes support a single high-end GPU or multiple NVMe drives, which is relevant for AI inference or data analytics workloads that require fast storage access. The 65-watt TDP makes it acceptable for always-on server environments where power consumption is a concern. Gamers are not the target audience, as the Xeon E series lacks the overclocking features and consumer-oriented optimizations of mainstream Core chips, though the single-threaded performance would not bottleneck most games.

How It Compares

Against the Intel Xeon D-2733NT, the E-2336 is a dead heat in aggregate performance, with both chips scoring 3984 and 3985 respectively, a 0% delta. The D-2733NT is a system-on-chip designed for network and edge deployments, so the choice between them comes down to platform features rather than raw speed. The E-2336 offers a higher boost clock (4.80 GHz vs. the D-2733NT's unspecified clocks), but the D-2733NT may include integrated networking that the E-2336 lacks.

The AMD Ryzen Threadripper 1900X scores 3995, which is 0.2% higher than the E-2336's 3985. This delta is negligible, but the 1900X is a legacy high-end desktop part with a different platform (TR4) that offers more PCIe lanes and quad-channel memory. The E-2336 counters with a lower TDP (65 watts vs. the 1900X's higher power draw) and ECC support, making it more suitable for dense server chassis. For raw multi-threaded workloads, the 1900X's 8-core design may edge out the E-2336 in longer render tasks, but the benchmark averages show parity.

The Intel Core i9-13900TE scores 3998, 0.3% ahead of the E-2336. This delta is within measurement variance, but the 13900TE is a hybrid architecture part with a different feature set, including integrated graphics and a newer socket. The E-2336's advantage lies in its ECC memory support and server-oriented stability validation, which the consumer 13900TE lacks. In single-threaded tests, the E-2336's 4.80 GHz boost clock likely keeps pace, but the 13900TE's efficiency cores may improve multi-threaded throughput in specific workloads.

The AMD Ryzen 7 PRO 5875U scores 3971, which is 0.4% lower than the E-2336. This mobile-oriented chip is designed for power efficiency rather than raw throughput, and its lower score reflects that. The E-2336 offers a higher boost clock (4.80 GHz) and more PCIe lanes (20 vs. the 5875U's typical 12-16), but the 5875U has integrated graphics and a much lower TDP. For a stationary server or workstation, the E-2336 is the more capable part, but the 5875U would be preferable in a compact, power-constrained appliance.
