Codenamed RD990; Four physical PCIe 2.0 ×16 slots @ x8 electrical which can be combined to create two PCIe 2.0×16 slots @ x16 electrical, six PCIe 2.0×1 lanes in various combinations of 1x 2x or 4x slots, and an additional PCIe 2.0x4 slot that does not exist on the 990x or 970 the chipset provides a total of 42 PCIe 2.0 lanes and 4 PCIe 2.0 for A-Link Express III solely in the Northbridge
Epyc (stylized as EPYC) is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture.Introduced in June 2017, they are specifically targeted for the server and embedded system markets.
Zen 3 is the name for a CPU microarchitecture by AMD, released on November 5, 2020. [2] [3] It is the successor to Zen 2 and uses TSMC's 7 nm process for the chiplets and GlobalFoundries's 14 nm process for the I/O die on the server chips and 12 nm for desktop chips. [4]
Zen 4 is the name for a CPU microarchitecture designed by AMD, released on September 27, 2022. [4] [5] [6] It is the successor to Zen 3 and uses TSMC's N6 process for I/O dies, N5 process for CCDs, and N4 process for APUs. [7]
The processor's architecture allows support of up to 32 processors on a single server motherboard. [5] [6] In 2018 MCST announced plans to produce the Elbrus-8SV, an upgraded version of the 8C with doubled performance. The CPU can process 576 Gflops and has a frequency of 1.5 GHz, as well as DDR4 support instead of DDR3.
Zen 5 ("Nirvana") [1] is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022, [2] launched for mobile in July 2024 and for desktop in August 2024. [3] It is the successor to Zen 4 and is currently fabricated on TSMC 's N4X process. [ 4 ]
