wikiAMD EPYC 4005 Grado
AMD EPYC 4005 series processors offer up to 16 Zen 5 CPU cores and are therefore successors of the AMD EPYC 4004 Raphael processors. The CPU cores are divided up to 2 Core Complex Dies (CCDs). The central I/O-Die offers a 2-channel DDR5 memory connection and 28 PCIe Gen 5.0 lanes. This article provides a tabular overview of the AMD EPYC 4005 series models.
Characteristics
AMD EPYC 4005 processors offer the following features or following characteristics:
- AMD Zen 5 cores (up to 2 CCDs / 16 cores)
- 1 MB L2-cache per core
- 32 MB L3-cache per CCD (64 MB maximum, 128 MB with AMD 3D V-cache)
- 2-channel DDR5 UDIMM up to 5.200 MHz with ECC support (for 1DPC - 1 Dimm per channel, for 2DPC 3.600 MHz)[1]
- maximum 192 GB RAM (for 2 DIMMs/channel)
- up to 28 PCIe 5.0 I/O lanes
- DisplayPort 2.0 / HDMI 2.1
