Xeon Gold 6142

The Xeon Gold 6142 is a 16-core / 32-thread processor based on the Skylake (server) (2017−2018) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3.7 GHz from a base frequency of 2.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 22 MB of L3 cache, plus 16 MB of L2 cache and 1 MB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 25,490, placing it in the High-End performance tier as a Legacy generation product.

The Xeon Gold 6142 fits into the LGA3647 socket and supports PCIe 3.0 with 48 total PCIe lanes for expansion cards and storage. It supports DDR4-2666 memory at speeds up to 2666 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 768 across 6 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: None — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the EPYC 7451.

The Xeon Gold 6142 has a rated TDP (Thermal Design Power) of 150 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: LGA3647 Server Grade.

Performance ranking position: #557 out of all indexed processors.
