'''EPYC 9654P''' is a {{arch|64}} [[96-core]] [[x86]] server microprocessor designed and introduced by [[AMD]] in late [[2022]]. This [[multi-chip package|multi-chip processor]], which is based on the {{amd|Zen 4|Zen 4 microarchitecture|l=arch}}, incorporates twelve Core Complex Dies fabricated on a [[TSMC]] [[5 nm process]] and a large I/O die also manufactured by TSMC. The 9654P has a TDP of 360 W with a base frequency of 2.4 GHz and a {{amd|precision boost|boost}} frequency of up to 3.7 GHz. This processor supports up to 6 TiB of 12 channel DDR5-4800 memory per socket.
