The Intel Xeon E-2456 is manufactured on a 10 nm semiconductor process and operates within a Thermal Design Power of 80W, with a maximum rated CPU temperature of 100 °C. It supports 64-bit computing and connects to compatible components via PCIe 5.0, providing high-bandwidth interfacing for modern storage and networking hardware. The processor does not include integrated graphics, so any display output requires a dedicated graphics solution.
The Intel Xeon E-2456 runs 6 cores at a base frequency of 3.3 GHz each, with multithreading bringing the total thread count to 12. Via Turbo Boost version 2, the processor can reach a peak of 5.1 GHz, making it well-oriented toward workloads that depend on strong per-core speed. The clock multiplier is fixed at 33 and cannot be adjusted. Rounding out the performance profile is 18 MB of L3 cache, allocated at 3 MB per core — a relatively generous ratio that helps reduce memory access latency during sustained, core-intensive tasks.
The Intel Xeon E-2456 uses DDR5 memory running at up to 4800 MHz across two channels, with a bus transfer rate of 16 GT/s. It supports a maximum of 128 GB of total memory, which fits the single-socket workstation and entry server configurations this processor is designed for. ECC memory support is included, providing hardware-level error detection and correction to maintain data reliability during continuous operation — a practical necessity in server and professional workstation environments.
The Intel Xeon E-2456 supports multithreading, allowing each of its physical cores to handle two threads concurrently for broader parallel task coverage. Its instruction set includes MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, covering hardware-accelerated paths for vector computation, floating-point operations, and encryption workloads. The processor also features NX bit support, which enables hardware-enforced separation between executable and non-executable memory regions — a foundational security measure relevant to server and professional workstation deployments.
In PassMark testing, the Intel Xeon E-2456 achieves an overall multi-threaded score of 20,507, reflecting its capacity across parallel workloads. Its single-threaded PassMark result of 3,552 is consistent with the high base and turbo clock frequencies this processor carries, indicating solid per-core execution speed for tasks that rely on sequential processing rather than broad thread distribution.
