AMD EPYC 9734

112C/224T · 3.0 GHz · 340 W

The EPYC 9734 is a 112-core, 224-thread model of AMD's Bergamo line, the cloud-native members of the 4th Gen EPYC 9004 series launched on June 13, 2023. It uses Zen 4c cores, a compact version of Zen 4 with the same instruction set and IPC but a smaller cache per core, letting AMD fit sixteen cores on each core chiplet. It has 256 MB of L3 cache, runs at 2.2 GHz base and up to 3.0 GHz boost, and shares the SP5 platform with Genoa, including twelve channels of DDR5-4800 memory and 128 PCIe 5.0 lanes. The default TDP is 340 W, configurable between 320 W and 400 W. It sits below the 128-core EPYC 9754 in the Bergamo lineup.
