52-core server processor for dense compute

The Intel Xeon Max 9470 is a 52-core, 104-thread server CPU built on 10 nm Sapphire Rapids silicon. It runs at a 2.0 GHz base frequency with a 3.5 GHz maximum turbo and provides 105 MB of L3 cache. The processor fits the LGA 4677 socket and supports 8-channel DDR5 memory up to 4 TB capacity.

Suits memory-heavy HPC and AI workloads

This chip targets high-performance computing, large-model inference and data-analytics tasks that benefit from high core counts and wide memory bandwidth. It is not suited for single-threaded applications that rely on peak frequency alone. Buyers who need more than two-socket scaling should look at other platforms. Workloads requiring integrated graphics or specialised media acceleration will not be served.

Sustained load at 350 W thermal design power

Under continuous heavy utilisation the processor operates at its 350 W TDP, demanding robust cooling infrastructure. The 80 PCIe 5.0 lanes maintain I/O throughput for accelerators and fast storage during long runs. Eight memory channels at up to 4800 MT/s per DIMM keep data flowing to all 52 cores without bottlenecks. AVX-512 and AMX units sustain vector and matrix throughput for extended periods.

Questions about this item

What motherboard socket is required for the Intel Xeon Max 9470?

The processor fits the LGA 4677 socket, so the motherboard must provide that exact socket.

Can the 52-core Xeon Max 9470 run in a single-socket server while keeping a second socket empty for later expansion?

The chip supports 2S scalability, meaning it operates correctly in a single-socket board with the second socket left unpopulated.

How do I verify the processor is reaching its 3.5 GHz max turbo frequency after installation?

Monitor core clocks under load using a tool such as turbostat or Intel PCM; sustained speeds at or near 3.5 GHz confirm intended turbo behaviour.
