Xeon Gold 6442Y

The Xeon Gold 6442Y is a 24-core / 48-thread processor based on the Sapphire Rapids (2023−2024) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 4 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 60 MB of L3 cache, plus 2 MB (per core) of L2 cache and 80K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 58,534, placing it in the Enthusiast performance tier as a Recent generation product.

The Xeon Gold 6442Y fits into the LGA4677 socket and supports PCIe 5.0 with 80 total PCIe lanes for expansion cards and storage. It supports DDR5-4800, DDR5-4400 memory at speeds up to 4800 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 4096 across 8 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 9354.

The Xeon Gold 6442Y has a rated TDP (Thermal Design Power) of 225 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: Premium Server Cooler.

At an average price of $2,878, the Xeon Gold 6442Y delivers 20 PassMark points per dollar. Performance ranking position: #141 out of all indexed processors.
