Xeon Platinum 8452Y 36-core processor
The Intel Xeon Platinum 8452Y is a 36-core desktop CPU built on the 10nm Sapphire Rapids architecture. It operates at a 2.0 GHz base frequency and reaches a 3.2 GHz maximum turbo frequency. The processor supports 72 threads and provides 67.5MB of L3 cache within a 300W thermal design power envelope. It fits the LGA 4677 socket and includes an integrated memory controller running at 4800 MHz.
Multi-socket servers and workstations
This processor suits dual-socket servers and high-core-count workstations that need 72 threads and eight-channel DDR5 memory with ECC support. It also provides 80 PCI Express 5.0 lanes and Intel AMX for matrix acceleration. Buyers who require a lower thermal design power, a single-socket platform, or a different core count should evaluate other models.
300W thermal design power
The 300W thermal design power is the key specification that determines whether this part fits the cooling and power infrastructure of the target system. A compatible LGA 4677 motherboard and a cooling solution rated for at least 300W are mandatory. No cooling device is included with the processor.

Questions about this item
What socket and board power delivery does the Xeon Platinum 8452Y require?
The processor fits an LGA 4677 socket and draws up to 300 W, so the motherboard must supply that power through the CPU VRM.
Which installation step is most often missed when seating this 36-core CPU?
Align the notches, lower the chip without tilting, then torque the independent loading mechanism in a cross pattern to the board-maker's spec — skipping the cross pattern leaves uneven contact.
What cooler maintenance will this 300 W processor need over time?
No cooler is included; plan to clean the heatsink fins and replace the thermal interface material every one to two years to sustain 300 W dissipation.
