AMD EPYC 7282 socket: SP3
The AMD EPYC 7282 uses SP3, the LGA socket for EPYC server processors. The 16-core chip at 120 W is the efficiency pick of its class.

What the EPYC 7282 is
The EPYC 7282 is a 16-core, 32-thread server processor from Rome. It launched in August 2019 for efficient virtualization with a 2.8 GHz base and up to 3.2 GHz boost at just 120 W. Sixty four megabytes of L3 serve sixteen cores.
The 120 W rating undercuts the 155 W 7302 at the same core count for power capped racks. Eight megabytes of L2 back general threads. Performance per watt leads the 16-core Rome range.
Dual socket scaling reaches 32 cores per box for efficient clusters. The 7282 suits dense colocation where power bills dominate. Buyers who need clocks over watts choose the 7302 instead.
Socket and motherboard compatibility
The EPYC 7282 fits SP3 on single and dual socket boards. Modest 120 W delivery runs on standard stages. Vendor lists confirm firmware.
Efficient dual socket pairs total 32 cores at 240 W for cool clusters. Single socket nodes sip power for edge virtualization. The How to find your CPU socket type guide maps server platforms.
Milan efficient SKUs later continued the same role on these boards with updates.
Memory, PCIe and cooling
DDR4 ECC spans 8 channels with 4-channel DDR4-2667 as performance optimized for this SKU. Balanced populations suit 16-core throughput per watt. ECC guards tenant data.
PCIe Gen4 lanes total 128 per socket for flash and networking. Efficient nodes still attach full NVMe cages. Dual socket builds reach 160 lanes.
The 120 W class cools with standard 1U heatsinks quietly. No boxed cooler exists. Low heat output keeps neighboring nodes cool.
Where this Rome part fits
Sixteen efficient cores fit virtualization farms, web tiers and storage controllers where watts matter. The 2.8 GHz base keeps response brisk without the 155 W premium. Sixty four megabytes of L3 cover mixed tenants.
Colocation racks standardize on dual socket 7282 pairs for 32 cool cores. Pair with moderate RAM and 10 Gb networking. The AMD EPYC 7302 trades watts for clocks nearby.
Power caps in firmware can pin nodes below 120 W where facilities demand it.
Upgrade paths
On SP3 clocks grow to the 155 W 7302 on the same boards, or cores grow to 24-core 7352. A second 7282 fills empty sockets first.
