Scalable 2S server processor

The Intel Xeon Platinum 8470Q is a 52-core server CPU built for two-socket platforms. It delivers 104 threads at a 2.1 GHz base frequency with a 3.8 GHz max turbo. The LGA 4677 socket supports eight DDR5 channels and up to 4 TB of memory. This processor targets data-centre workloads that need high core density and large memory capacity.

Sustained multi-threaded throughput

Under continuous load the 52 cores maintain the 2.1 GHz base clock across all threads. The 105 MB L3 cache reduces latency for memory-bound tasks while the eight-channel DDR5 controller feeds data at up to 4800 MT/s per channel. PCIe 5.0 with 80 lanes provides high-bandwidth I/O for storage and accelerators without bottlenecks during extended runs.

Thermal envelope and power profile

The processor carries a 350 W thermal design power and ships without a cooling device. System integrators must provide a solution rated for that heat output in a dual-socket chassis. Power draw scales with active core count and memory traffic, so adequate airflow and voltage regulation are essential for stable operation at the 10 nm manufacturing node.

Questions sur cet article

How much heat does the 350 W Xeon Platinum 8470Q produce under sustained load?

The processor has a thermal design power of 350 W, so sustained full-load operation will dissipate that much heat and requires a server-grade cooling solution rated for at least 350 W.

What memory must I already own for the 8-channel DDR5 controller to run at 4800 MT/s?

You need DDR5 RDIMMs rated for 4800 MT/s; populate one DIMM per channel across all eight channels to reach the 1DPC speed of 4800 MT/s.

Will the LGA 4677 socket and PCIe 5.0 lanes work with my existing dual-socket Sapphire Rapids board?

Yes, the CPU fits the LGA 4677 socket, supports 2S scalability and provides 80 lanes of PCIe 5.0, matching a dual-socket Sapphire Rapids platform.
