A confidential document from AMD showing the specifications of the upcoming Ryzen 4000 “Vermeer” processors has been leaked. Dated from June 10th, the document tells us that the upcoming Ryzen 4000 processors will feature up to 2 CCX with 8 cores each, resulting in a maximum core count of 16 and a maximum thread count of 32.
The document also refers to the Ryzen “Vermeer” architecture as AMD’s Family 19h Model 20h-2Fh B0, For those who don’t know, Zen(+) and Zen 2 were referred to as Family 17h. At first glance, both the Ryzen 3000 and the upcoming Ryzen 4000 processors may look similar, but a few significant differences might make them quite distinct.
As per the document shared by CyberPunkCat (via Tom’sHardware), the Ryzen 4000 processors will feature a CCX per CCD, unlike previous generations, with a maximum of two CCDs and an I/O die. Each CCX will come with up to 8 cores running in single thread or two thread mode, resulting in up to 16 threads per CCD. L2 cache will be limited to 512KB per core, with a maximum of 4MB per CCD, and 32MB of L3 cache shared across all cores in each CCD.
Other interesting specifications listed in the document include supporting up to 512GB per DRAM channel or up to 1TB of ECC DRAM, clocked between 1333MHz and 3200MHz. These CPUs will also feature 2 unified memory controllers, with each supporting a single DRAM channel.
More details about the Ryzen 4000 processors will be unveiled on October 8th, during an AMD virtual event.
