Intel Xeon E5-2673 v4 20-Core 40-Thread Server Processor

The Intel Xeon E5-2673 v4 is a high-core-count server processor from the Broadwell-EP generation, designed for enterprise servers, virtualization platforms, cloud infrastructure, rendering systems, database servers, and other heavily multi-threaded workloads.

Featuring 20 physical cores and 40 processing threads, the E5-2673 v4 provides substantial parallel processing capability. Commonly documented specifications for this OEM-oriented processor include a 2.30GHz base frequency, up to 3.30GHz Turbo frequency, 50MB L3 cache, 135W TDP, and FCLGA2011-3 socket.

20 Cores and 40 Threads

With 20 physical CPU cores and Intel Hyper-Threading Technology providing 40 processing threads, the E5-2673 v4 is particularly suitable for workloads that benefit from a large number of simultaneous processing threads.

2.30GHz Base / Up to 3.30GHz Turbo

The processor operates at a base clock frequency of 2.30GHz and is commonly documented with a maximum Turbo frequency of up to 3.30GHz. This provides a useful combination of high core count and additional frequency for workloads that cannot fully utilize all available cores.

50MB L3 Cache

A large 50MB last-level cache helps keep frequently accessed data close to the processor cores, supporting demanding virtualization, database, rendering, and enterprise computing workloads.

Broadwell-EP 14nm Architecture

The Xeon E5-2673 v4 belongs to Intel's Broadwell-EP generation and uses a 14nm manufacturing process. It is part of the same general platform generation as the Xeon E5-2600 v4 family.

LGA2011-3 Server Platform

The processor uses the FCLGA2011-3 socket and is intended for compatible enterprise server platforms. Compatible systems may support one or two processors depending on the motherboard and system design.

DDR4 Server Memory Platform

Broadwell-EP Xeon E5 v4 platforms use four-channel DDR4 memory controllers and are commonly deployed with ECC Registered server memory. Actual supported memory speed, capacity, DIMM type, and population rules depend on the server or motherboard.

Ideal for Virtualization

The combination of 20 cores and 40 threads makes the E5-2673 v4 particularly attractive for virtualization environments where multiple virtual machines or containers need to operate simultaneously.

Important OEM Processor Information

The Xeon E5-2673 v4 is unusual compared with standard retail Xeon E5 v4 processors because it is not currently included in Intel's normal ARK E5 v4 product listing. Intel has explained that processors absent from ARK may be tray products, engineering samples, or custom processors designed for specific system manufacturers.

For this reason, buyers should verify the processor's markings and compatibility with the exact server or motherboard before purchase, especially when using the CPU in systems from Dell, HPE, Lenovo, Supermicro, or other manufacturers.
