Server-grade compute core

The Intel Xeon Platinum 8470N is a 52-core processor built for dual-socket servers that run heavily threaded workloads. Its 104 threads and 97.5 MB L3 cache suit virtualization hosts, database nodes and high-performance computing clusters.

Platform integration needs

The chip drops into an LGA 4677 socket and exposes 80 lanes of PCI Express 5.0 for accelerator cards and fast storage. Eight memory channels accept DDR5 at up to 4800 MT/s with one DIMM per channel or 4400 MT/s with two, so the board must provide matching slots and robust power delivery for the 300 W thermal design power.

Memory and throughput ceiling

Maximum supported capacity reaches 4 TB of DDR5 across the eight channels, giving ample headroom for in-memory databases and large VM fleets. The 1.7 GHz base frequency and 3.6 GHz max turbo frequency deliver steady throughput, while the 300 W envelope and lack of included cooling mean the chassis must supply adequate airflow.

Questions about this item

Will the 300 W thermal design power force the 52-core processor to throttle during continuous all-core workloads?

The 300 W TDP is the sustained power limit; with adequate cooling the 52 cores can run at base 1.7 GHz indefinitely without thermal throttling.

How loud and hot does the Xeon Platinum 8470N get when the 104 threads run 24/7 at 3.6 GHz turbo?

No cooler is included; noise and temperature depend entirely on the chosen heatsink or liquid loop rated for 300 W continuous dissipation.

Which DDR5 memory kit must I already own to populate the 8-channel controller at 4800 MT/s?

Eight DDR5-4800 modules, one per channel (1 DPC), are required to reach the rated 4800 MT/s speed across all 8 channels.
