Xeon Gold 6142M Details

Ranking #277 of 2060 in overall performance, the Intel Xeon Gold 6142M presents a compelling option for server environments requiring balanced single-threaded responsiveness and robust multi-threaded throughput. As of March 2026, the processor remains relevant in its segment despite being based on the Skylake-SP architecture, which was introduced several years prior. Its 16 cores and 32 threads, enabled by simultaneous multithreading, deliver a solid multicore score of 6481, placing it ahead of many consumer-grade and mid-tier server processors. However, its single-core performance of 5544, ranking #522, indicates that while capable, it does not compete with the latest high-frequency consumer CPUs or top-tier workstation parts.

Built on a 14 nm process and fabricated using CMOS technology, the Xeon Gold 6142M operates at a base frequency of 2.6 GHz with a turbo frequency of up to 3.7 GHz. It features a substantial cache hierarchy, including 0.5 MiB of L1 cache (split into 0.5 MiB for data and 0.5 MiB for instructions), 16 MiB of L2 cache, and a large 22 MiB L3 cache, which helps sustain performance under heavy workloads. The processor supports up to 1,572,864 MiB of DDR4-2666 memory across six channels, delivering a maximum memory bandwidth of 119.21 GiB/s. This makes it well-suited for memory-intensive applications such as virtualization, databases, and scientific computing.

The Xeon Gold 6142M is designed for the Intel Purley platform and uses the FCLGA-3647 socket, supporting up to four CPUs in a multi-socket configuration. It has a TDP of 150 W, indicating a focus on performance over power efficiency, and is intended for high-end server and workstation environments. The chip supports a range of advanced features, including AVX-512, AES-NI, Intel VT-x and VT-d for virtualization, and Intel vPro for enterprise management. Its inclusion of ECC memory support ensures data integrity, which is critical in server-grade systems.

In benchmarking, the Xeon Gold 6142M holds a passmark overall score of 5919, with individual scores of 5394 in number crunching, 5585 in data processing, and 5569 in physics compute. These results reflect a well-rounded processor that performs adequately across a variety of workloads. While it trails behind modern high-end processors like the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, it holds its own against other server-grade Xeons such as the Xeon Gold 6138 and Xeon Gold 6140. Its most notable strength lies in multicore performance, where it outperforms many older and lower-tier server CPUs.

In conclusion, the Intel Xeon Gold 6142M remains a viable choice for enterprise and data center environments that prioritize multi-threaded performance and memory capacity. While its single-core performance is not class-leading, its robust core count, large cache, and extensive feature set make it suitable for virtualization, cloud computing, and high-throughput applications. It is best positioned as a workhorse in multi-socket server systems rather than a consumer-focused CPU.
