AMD has confirmed that its Zen 3 processors will debut on October 8, and now it may have unknowingly revealed what we can expect from the next-generation processors. An alleged internal AMD document, dating from June 10, was shared by computer scientist CyberPunkCat, confirming that Ryzen 4000 processors will be known as the AMD 19h Model 21h B20 family. AMD's current Zen and Zen 2 processors are in the 17h family, so the 19h family likely refers to its next-generation Zen 3 architecture. The leaked document reveals that the family of processors, dubbed ``Vermeer'', can be designed for use in high-performance desktop platforms, comprising up to two CCDs (Core/Cache Complex Dies) and a single die. from. In Zen 2, each CCD houses two CCXs (Core Complexities), but in Zen 3, there is only one CCX hat which will have up to 8 cores running in single-thread (1T) mode or in a two-thread (2T) model up to 16 threads per CCX, according to the paper. This means, at least in theory, that the number of cores and threads will reach 16 cores and 32 threads, which is the same as the existing flagship AMD Ryzen 9 3950X. The alleged internal document also reveals that Zen 3 supports up to 512 GB per DRAM channel or up to 1 TB of ECC DRAM, clocked between 1333 MHz and 3200 MHz. Ryzen 4000 processors will also feature two unified memory controllers, each with a single DRAM channel. The leak doesn't tell us much about the performance we can expect from Ryzen 4000 processors, but previous rumors suggest that Zen 3 will offer roughly 15-17% better IPC (Instructions Per Clock) performance compared to the previous one. Zen 2, which should have worried Intel if this is true. With AMD planning to introduce its Ryzen 4000 processors in just a few weeks on October 8, we don't have to wait much longer to find out if that's true.
