AMD EPYC 7452 socket: SP3
The AMD EPYC 7452 uses SP3, the LGA socket for EPYC server processors. The 32-core chip at 155 W is the efficiency leader of its class.

What the EPYC 7452 is
The EPYC 7452 is a 32-core, 64-thread server processor from Rome. It launched in August 2019 for efficient dense clouds with a 2.35 GHz base and up to 3.35 GHz boost at just 155 W. Four chiplets share 128 MB of L3.
Thirty two cores inside 155 W set efficiency records for virtualization hosts. Sixteen megabytes of L2 back batch threads. Burst to 3.35 GHz keeps interactive work responsive despite the modest base.
Dual socket scaling reaches 64 efficient cores per box for cool clusters. The 7452 undercuts the 180 W 7502 on power for throughput billing. Throughput clouds that pay power bills fit here.
Socket and motherboard compatibility
The EPYC 7452 fits SP3 on single and dual socket boards. Standard 155 W delivery covers it on most server boards. Vendor lists confirm firmware.
Efficient dual socket pairs total 64 cores at 310 W for cool dense rows. Power capping can pin nodes lower where facilities demand. The How to find your CPU socket type guide maps server sockets.
Milan efficient SKUs later continued the role on these boards with updates.
Memory, PCIe and cooling
Eight DDR4-3200 ECC channels feed 64 threads at full bandwidth. Dense nodes pair a terabyte with 32 cores. All channels filled avoids bandwidth collapse.
PCIe Gen4 lanes total 128 per socket for flash and networking. Efficient tenants share lanes through switches where needed. Dual socket builds reach 160 lanes.
The 155 W class cools with standard dense heatsinks. No boxed cooler exists. Per core heat stays low across four chiplets.
Where this Rome part fits
Thirty two efficient cores fit web tiers, CI fleets and storage controllers billed by throughput. Low base clocks matter little for parallel batches. The 128 MB L3 smooths shared caches.
Colocation providers standardize on dual socket 7452 pairs for 64 cool cores. Pair with moderate RAM and 25 Gb networking. The AMD EPYC 7502 trades watts for base clocks nearby.
Confirm board power and thermals before filling racks with dense nodes.
Upgrade paths
On SP3 clocks grow to the 180 W 7502 on the same boards, or density grows to 48-core 7552. Milan efficient parts follow with firmware.
SP5 platforms bring DDR5 density later. The CPU cooler compatibility by socket guide covers cooling classes.
