'''EPYC 7252''' is a {{arch|64}} [[octa-core]] [[x86]] server microprocessor designed and introduced by [[AMD]] in mid-[[2019]]. This [[multi-chip package|multi-chip processor]], which is based on the {{amd|Zen 2|Zen 2 microarchitecture|l=arch}}, incorporates logic fabricated [[TSMC]] [[7 nm process]] and I/O fabricated on [[GlobalFoundries]] [[14 nm process]]. The 7252 has a TDP of 120 W with a base frequency of 2.8 GHz and a {{amd|precision boost|boost}} frequency of up to 3.2 GHz. This processor supports up to two-way [[symmetric multiprocessing|SMP]] and up to 4 TiB of eight channels DDR4-3200 memory per socket.
