Xeon Gold 6142 Details

Ranking #343 of 2060 in overall performance, the Intel Xeon Gold 6142 sits firmly in the mid-tier of server-grade processors as of March 2026. While not a top performer compared to modern high-end chips like the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, it remains a capable option for workloads requiring substantial multi-threaded throughput and enterprise-level features. Built on the Skylake SP microarchitecture and fabricated on a 14 nm process, this 16-core, 32-thread processor offers a base clock of 2.6 GHz and a turbo boost up to 3.7 GHz, making it well-suited for data center environments where consistent performance and reliability are paramount.

The Xeon Gold 6142 features a robust cache hierarchy, including 0.5 MiB of L1 instruction and data cache per core, 16 MiB of L2 cache, and a large 22 MiB L3 cache shared across all cores. It supports up to 768 GiB of DDR4-2666 memory across six channels, delivering a peak memory bandwidth of 119.21 GiB/s. With a TDP of 150 W and a socket type of FCLGA-3647, it is designed for high-density server platforms, particularly those using the Purley platform and Intel’s Lewisburg chipset.

One of the key strengths of this processor is its support for advanced instruction sets, including AVX-512, AVX2, AES-NI, and Intel’s Transactional Synchronization Extensions (TSX). These features enhance performance in scientific computing, virtualization, and encryption-heavy applications. Additionally, the chip supports ECC memory, Intel VT-x and VT-d virtualization technologies, and Intel vPro for remote management and security, making it ideal for enterprise and cloud infrastructure.

In benchmark testing, the Xeon Gold 6142 achieves a single-core score of 5485, placing it at #562 among 2060 processors, and a multicore score of 6125, ranking #214. Its overall score of 5741 reflects a balance between core count and frequency, though it trails behind newer processors like the Xeon Gold 6334 and 6248. While it outperforms some older server chips such as the Xeon E5-2696 v3 and Ryzen Threadripper 2920X, it is notably slower than many modern high-end consumer and workstation CPUs.

Despite being released several years ago, the Xeon Gold 6142 remains a viable choice for legacy server systems, entry-level cloud computing, and virtualization workloads where cost-efficiency and compatibility are priorities. Its strong multicore performance and enterprise-grade features continue to make it relevant in environments that don't require the latest silicon, particularly where long-term support and stability are more important than raw performance.
