28-Core Xeon for dense servers
The Intel Xeon Platinum 8450H delivers 28 cores and 56 threads in a LGA 4677 package built for multi-socket platforms. Its 2.0 GHz base frequency scales to 3.5 GHz turbo when thermal headroom allows. The 75 MB L3 cache feeds data to all cores without leaving the die. This processor targets high-density compute nodes where core count per socket drives licensing and rack efficiency.
250 W TDP demands directed airflow
At 250 W thermal design power the chip moves significant heat under sustained loads and requires server-grade heatsinks with high-static-pressure fans. No cooling device is included in the box. Eight-channel DDR5 support at up to 4800 MT/s per DIMM adds memory-subsystem power that the platform cooling must also dissipate. Acoustic output will follow the chassis fan curves configured for the target inlet temperature.
LGA 4677 socket and 80 PCIe 5.0 lanes
The flip-chip land-grid array seats in a keyed LGA 4677 socket with a dedicated retention mechanism; handling requires even pressure to avoid bent contacts. Eighty lanes of PCI Express 5.0 connect directly to the CPU for accelerators, storage controllers or high-speed networking without chipset bottlenecks. S8S scalability enables eight-socket configurations using Intel UPI links routed through the system board.

Questions about this item
How do I install the Xeon Platinum 8450H into an LGA 4677 socket without bending pins?
Align the processor triangle marker with the socket corner, lower it vertically without force, then secure the retention lever fully; the step most often missed is verifying the load-plate sits flush before locking.
What maintenance or replacement will the 250 W Xeon Platinum 8450H require over its service life?
The processor itself has no user-serviceable parts; plan to replace thermal interface material every two to three years and ensure the chosen heatsink or liquid cold plate is rated for 250 W continuous dissipation.
At what point does the 250 W thermal design power become the limiting factor during sustained all-core workloads?
When all 28 cores run near 3.5 GHz turbo, package power hits 250 W; if the cooling solution cannot move that heat, the processor will throttle frequency to stay within its thermal envelope.
