32-Core Xeon 676X for single-socket servers

The Intel Xeon 676X Granite Rapids processor delivers 32 performance cores and 64 threads in a single LGA 4710 package. It targets single-socket server deployments that need high core density and large cache. The 144MB L3 cache and eight-channel DDR5 memory controller support up to 4TB of system memory.

275W base power with 330W max turbo

Thermal design power is rated at 275W, rising to 330W under maximum turbo conditions. The Intel 3 manufacturing process and Granite Rapids architecture manage heat at the 2.8 GHz base frequency across all 32 cores. Cooling solutions must handle sustained output at this power level.

Sustained 4.7 GHz all-core turbo with 4.9 GHz peak

Under continuous load the processor runs at up to 4.7 GHz via Intel Turbo Boost Technology 2.0. Short bursts can reach 4.9 GHz through Turbo Boost Max Technology 3.0. The 128 PCIe 5.0 lanes and instruction sets including AVX-512 and AMX maintain throughput during extended compute workloads.

Questions about this item

How do I install the Xeon 676X into an LGA 4710 socket without bending pins?

Align the gold triangle on the processor with the socket corner, lower it straight down without force, then engage the Independent Loading Mechanism lever fully; the step most people miss is verifying the carrier sits flat before locking the lever.

What replacement interval should I plan for the thermal interface material on this 275W processor?

Replace the thermal paste every two to three years or whenever the cooler is removed; sustained 275W base power and 330W turbo power accelerate paste pump-out and dry-out.

At what power ceiling does the Xeon 676X hit its first sustained-use limit?

The processor will throttle once package power reaches the 330W Max Turbo Power limit, which occurs before thermal limits under continuous all-core AVX-512 workloads.
