Processor Intel Xeon W-3345 3 GHz 36 MB LGA 4189

The Intel Xeon W-3345 is a workstation-class processor based on the Ice Lake architecture. It operates at a base frequency of 3.0 GHz with a boost up to 4.0 GHz, provides 24 physical cores and 36 MB of shared cache, and supports octa-channel DDR4 memory configurations up to 4 TB. Built on a 10 nm process and compatible with the LGA 4189 socket, this CPU targets demanding professional workloads that benefit from AVX-512 acceleration and high memory capacity.

Advantages

The processor combines multiple server-grade features such as AVX-512 support, large shared cache, and octa-channel memory to deliver high throughput for compute- and memory-intensive tasks. Hardware virtualization, security and performance technologies are included to improve workload isolation, encryption performance, and single-thread burst speed when required.

Suitable for

• Workstation CAD, 3D rendering and visualisation workloads
• Scientific computing and engineering simulations using wide-vector instructions
• Virtualised workstation environments and software development with heavy multitasking
• Large in-memory datasets, databases and analytics that require high memory capacity

When it may not be suitable

This processor is intended for professional workstations and servers; it is not optimized for mainstream desktop use where power consumption, platform cost, or integrated graphics are primary concerns. Systems that rely on on-board graphics will require a separate GPU since this model does not include integrated graphics.

How to use

Install the processor into a compatible LGA 4189 motherboard following the motherboard and processor manufacturer instructions. Pair with ECC-capable DDR4 memory in octa-channel configuration to make full use of memory bandwidth and capacity. For workloads that require GPU acceleration or display output, install a discrete graphics card. Enable necessary platform features (for example, virtualization or Intel SGX) in the system BIOS/UEFI and ensure up-to-date chipset drivers and firmware for optimal performance and security.

What to consider before purchase

• Compatibility with LGA 4189 socket and motherboard vendor support
• Required memory type and capacity (DDR4, ECC support) and cooling solution for a high-core-count CPU
• Platform cost including server/workstation motherboard, power delivery, and possible discrete GPU
• Whether AVX-512 and other instruction extensions are utilised by your software

Recommendations

For maximum performance, use validated workstation motherboards with robust power delivery, populate memory in balanced octa-channel configurations, and keep firmware and drivers updated. Enable relevant CPU features in BIOS only if supported by your operating system and applications.
