28-core Xeon Gold 6238R server processor
The Intel Xeon Gold 6238R is a 28-core server processor built on the Cascade Lake architecture. It delivers 56 threads with a base frequency of 2.20 GHz and a maximum turbo frequency of 4.00 GHz. This CPU is designed for multi-socket server platforms requiring high core density and 64-bit compute capability.
LGA 3647 socket compatibility
This processor requires a motherboard with an LGA 3647 socket, also referenced as FCLGA3647. It supports six memory channels with a maximum capacity of 1 TB and communicates via a 10.4 GT/s QPI link. PCI Express 3.0 lanes provide I/O connectivity for storage and networking expansion cards.
No cooler included in the package
The processor is sold as a tray unit without a cooling device. System integrators must source a compatible heatsink or liquid cooling solution rated for the 165 W thermal design power. Virtualization technology support is enabled for hypervisor deployments.

คำถามเกี่ยวกับสินค้านี้
What does the 2.20 GHz base frequency mean once the Xeon 6238R is installed in a server?
The 2.20 GHz base clock is the guaranteed minimum speed across all 28 cores under sustained load, so multi-threaded workloads run at least at this frequency.
What does the 10.4 GT/s QPI link cap in practice for the Xeon 6238R?
The 10.4 GT/s QPI interconnect limits inter-socket bandwidth to that rate, so dual-socket traffic cannot exceed this throughput.
What does the Xeon 6238R physically need to fit in a server chassis?
It requires an LGA 3647 socket and a cooler rated for 165 W TDP, as no cooling device is included with the processor.
