'''EPYC 7282''' is a {{arch|64}} [[hexadeca-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 two compute dies fabricated on a [[TSMC]] [[7 nm process]] and an I/O die fabricated on a [[GlobalFoundries]] [[14 nm process]]. The 7282 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 memory per socket.

This model supports up to 8 channels of up to DDR4-3200 memory<ref name="specs">[https://www.amd.com/en/products/cpu/amd-epyc-7282 "AMD EPYC™ 7282"]. <i>AMD.com</i>.

According to AMD this processor is "optimized for 4 channels with DDR4-2667 DIMMs" (≈ 21.3 GB/s per channel) and therefore has a "per-socket theoretical memory bandwidth 85.3 GB/s" (≈ 79.47 GiB/s).<ref name="datasheet"/>
