What the Xeon Platinum 9282 is
The Xeon Platinum 9282 is the Cascade Lake-AP flagship with 56 cores and 112 threads. It launched in the second quarter of 2019 with a 2.6 GHz base and up to 3.8 GHz boost at 400 W. Intel built it for the densest HPC and AI training nodes of its generation.
Seventy seven megabytes of Smart Cache feed large parallel working sets. The high base clock for a 56 core part sustains throughput where many cores stay active. Boost aids serial setup before massive parallel phases.
No integrated graphics is included. The process is 14 nm. Twelve channel DDR4 ECC feeds memory hungry codes. The 400 W class needs flagship node cooling with careful power delivery.
Socket and motherboard compatibility
The 9282 solders to BGA 5903 permanently. Vendors build 400 W boards with premium power stages and liquid ready heatsinks. There is no socketed alternative.
DDR4-2933 ECC in twelve channels provides the bandwidth that 112 threads demand. Large memory footprints suit simulation checkpoints. The How to find your CPU socket type guide confirms FC-BGA5903 in node specs.
LGA 3647 nodes cannot host this dual die BGA. Platform, power and cooling all differ. Node replacement is the service path.
Memory, PCIe and cooling
DDR4-2933 ECC RDIMMs in twelve channels maximize bandwidth for 56 cores. Populate all channels for best results. Capacity choices lock with the node order.
PCIe 3.0 from the processors connects accelerators and NVMe at data center rates. Fabric adapters benefit most from the high core count. Vendor diagrams show exact slot wiring.
Cooling at 400 W is data center grade with high airflow or direct liquid. Mounting pressure must be even across the large soldered package. No retail solution applies.
Upgrade paths
Soldered assembly blocks upgrades. Faster storage and fabric refreshes stretch cluster value. New nodes bring core gains.
Within BGA 5903, the Intel Xeon Platinum 9242 offers 48 cores at 350 W for slightly lower power. The Intel Xeon Platinum 9221 gives 32 cores at 250 W for efficiency focused racks. All share the same service model.
Past BGA 5903 later Xeon Max and Scalable families move to new sockets. The 9282 remains the density peak where 56 cores must endure.
