'''EPYC 7443P''' is a {{arch|64}} [[24-core]] [[x86]] server microprocessor designed and introduced by [[AMD]] in March [[2021]]. This [[multi-chip package|multi-chip processor]], which is based on the {{amd|Zen 3|Zen 3 microarchitecture|l=arch}}, incorporates four Core Complex Dies fabricated on a [[TSMC]] advanced [[7 nm process]] and a large I/O die manufactured by [[GlobalFoundries]]. The 7443P has a TDP of 200 W with a base frequency of 2.85 MHz and a {{amd|precision boost|boost}} frequency of up to 4 MHz. This processor supports  up to 4 TiB of eight channel DDR4-3200 memory per socket.
