FAQs

Q: Is the Xeon 6781P a single-socket or dual-socket processor?
A: The Xeon 6781P supports single-socket (1S) configurations only, so it is intended for single-processor ProLiant Gen12 servers.

Q: Which HPE server is this processor listed for?
A: It is listed as a supported single-socket CPU option in the HPE ProLiant Compute DL320 Gen12 QuickSpecs. Confirm compatibility with your specific Gen12 model before ordering.

Q: What memory does the Xeon 6781P support?
A: It provides eight memory channels supporting DDR5-6400 and MRDIMM-8800 with ECC, up to 4TB in total, subject to the memory options of the host server.

Q: What socket does this CPU use?
A: It uses the FCLGA4710 socket, so it is not compatible with earlier Xeon platforms or Gen11 and older servers.

Q: How many cores and threads does it have?
A: The processor has 80 cores and 160 threads, with a 2.0GHz base clock, 3.2GHz all-core turbo and up to 3.8GHz max turbo.

Q: Does it support AI acceleration?
A: Yes. It includes Intel AMX and Deep Learning Boost for AI inference, along with QuickAssist, Dynamic Load Balancer, Data Streaming and In-memory Analytics accelerators.
