Description
Intel Xeon W W3-2423 Processor brings workstation-grade power with its Q1'23 launch, designed for professionals who need reliable multi-threaded performance.
This Intel Xeon W W3-2423 (Sapphire Rapids) is a 6-core, 12-thread workstation CPU with a 2.1 GHz base frequency and up to 4.2 GHz turbo, offering a balanced mix of sustained throughput and peak single-thread performance for demanding tasks.
With 15 MB of Smart Cache and a 120 W base power (up to 144 W turbo), the W3-2423 is built for heavy compute workloads while maintaining predictable thermal and power characteristics in LGA 4677 (Socket E) platforms.
Memory support is robust, featuring quad-channel DDR5 up to 4400 MHz and up to 2 TB of addressable memory, including ECC support for data integrity—an essential advantage in professional applications and large datasets.
The processor includes advanced technologies such as Intel Turbo Boost, Hyper-Threading, AVX-512 and AVX2 vector extensions, AMX, Intel DL Boost, Intel VT-x/VT-d virtualization, Intel Total Memory Encryption, and platform security features like Boot Guard and CET, making it suitable for secure, virtualized, and accelerated compute scenarios.
This tray-packaged (OEM) CPU supports up to 64 PCIe 5.0 lanes and a DMI4 bus, enabling high-bandwidth I/O for storage, networking, and accelerators, while being targeted at single-socket (1S) workstation deployments with professional reliability.
Typical use cases include 3D rendering, CAD, engineering simulations, software development with heavy parallel builds, virtualization hosts for small labs, and media encoding where AVX and DL Boost acceleration improve throughput.
Key selling points: high single-core boost to 4.2 GHz, 6 cores/12 threads, DDR5 quad-channel ECC support, 64 PCIe 5.0 lanes, and an emphasis on workstation-class security and manageability.
