16-core Xeon for multi-socket servers

The Intel Xeon Gold 6242 delivers 16 cores and 32 threads at a 2.80 GHz base frequency with a 3.90 GHz maximum turbo. It fits the FCLGA3647 socket and is built on the Cascade Lake core for dual-socket and quad-socket server platforms. The 150 W thermal design power requires adequate server cooling infrastructure.

PCIe 3.0 and six-channel memory limits

This processor provides 48 lanes of PCI Express 3.0 and supports six memory channels up to 2933 MHz. The 10.4 GT/s bus speed connects CPUs in multi-socket configurations. Maximum addressable memory is 1 TB across the populated channels, so very large in-memory workloads may exceed the platform ceiling.

22 MB L3 cache sizing

The shared 22 MB L3 cache is the fixed on-die capacity that determines how much hot data stays close to the 16 cores. Workloads with larger working sets will spill to main memory more often, reducing throughput. No larger cache option exists on this part number.

Questions about this item

Should I pick the 16-core 2.80 GHz model or a different core count for my workload?

This SKU is a single 16-core, 32-thread Cascade Lake part with 22 MB L3 cache; other core counts are separate model numbers not covered here.

What does the 3.90 GHz max turbo deliver in a real server?

Under heavy load the processor can lift from its 2.8 GHz base to 3.90 GHz on active cores, raising single-thread throughput while staying within the 150 W thermal envelope.

How does the 10.4 GT/s bus and PCIe 3.0 x48 limit expansion?

The 10.4 GT/s UPI links and 48 PCIe 3.0 lanes cap interconnect bandwidth and device connectivity to the levels defined by the Cascade Lake platform.
