The first generation of processors is based on Zen microarchitecture using several processor complexes connected by bus ^[2] ; processors went on sale June 20, 2017.

The trademark unites 12 models of processors of the 7000 series. All processors, with the exception of models with the P index, are capable of working in motherboards with two processor sockets ^[3] .

The number of cores in AMD EPYC varies from 8 to 32 pieces. Each physical core is capable of handling two logical threads . Thus, the number of logical cores varies from 16 to 64 pieces, depending on the processor model. In dual-processor systems, the number of physical cores can reach 64 pieces, and the number of logical cores - 128 pieces.

The processors support working with DDR4 standard memory , including error correction, with a total volume of up to 2 TB .

In 2019, the second generation of these processors will be released.

The number of cores in AMD EPYC (Rome) varies from 8 to 64 pieces.

The processors support working with DDR4 standard memory , including error correction, with a total volume of up to 4 TB .
