Server processor for single-socket systems

The Intel Xeon 638 is a 16-core, 32-thread CPU built for single-socket servers. It runs at a 3.2 GHz base frequency with turbo up to 4.8 GHz. The 72 MB L3 cache and Intel 3 process target compute-intensive workloads that fit within one socket.

LGA 4710 socket with 180 W TDP

The LGA 4710 mounting requires a compatible server board and a cooler rated for 180 W base power. Turbo peaks at 216 W, so thermal headroom matters. Quad-channel DDR5 6400 MHz support and 80 PCIe 5.0 lanes demand a platform wired for that bandwidth.

Single-socket scalability limits expansion

Scalability is restricted to 1S only, so multi-socket clusters are not possible. Maximum memory capacity stops at 2 TB across four channels. PCIe 5.0 provides 80 lanes, but total I/O is bounded by the single-socket design. Instruction support includes AVX-512 and AMX for vector and matrix work.

Въпроси за този артикул

What does PCI Express 5.0 with 80 lanes mean for bandwidth?

The processor exposes 80 lanes of PCIe 5.0, letting each lane run at 32 GT/s for high-throughput storage or accelerator cards.

What cooler clearance and power delivery does the LGA 4710 socket require?

The LGA 4710 socket demands a 180 W TDP cooler with compatible mounting holes and a motherboard VRM rated for 216 W max turbo power.

How is the CPU installed and which step is often missed?

Align the notches, seat the processor gently, close the load plate, then torque the retention screws in a cross pattern to the spec in the motherboard manual.
