General Info
Microarchitecture

EPYC 7742 is a 64-bit 64-core x86 server microprocessor designed and introduced by AMD in mid-2019. This multi-chip processor, which is based on the Zen 2 microarchitecture, incorporates logic fabricated TSMC 7 nm process and I/O fabricated on GlobalFoundries 14 nm process. The 7742 has a TDP of 225 W with a base frequency of 2.2 GHz and a boost frequency of up to 3.4 GHz. This processor supports up to two-way SMP and up to 4 TiB of eight channels DDR4-3200 memory per socket.
