The official introduction of AMD's Ryzen 3000 Zen 2 processors and the accompanying X570 chipset are just days away. We already know quite about the processors and supporting chipset courtesy of leaks, and today we're learning about official memory specs for the Ryzen 3000 desktop processor family.
According to momomo_us, which has already provided us with a multitude of leaks on upcoming Ryzen and Radeon Navi products, Ryzen 3000 processors will include official support for the JEDEC DDR4-3200 memory specification. For those keeping score, first-generation Ryzen 1000 processors (Zen) supported up to DDR4-2666, while second-generation Ryzen 2000 processors (Zen+) bumped that to DDR4-2933.
The DDR4-3200 spec means that memory modules for X570 motherboards will have an effective rate of 3.2GHz providing 25.6GB/sec of bandwidth per channel. Given that Ryzen motherboards support dual-channel memory, we're looking at total bandwidth of 51.2GB/s.
A screenshot provided by momomo_us suggests Ryzen 3000 processors can push DDR4-4400+ speeds when overclocked. We'll get official confirmation of the stock and OC speeds once motherboard manufacturers start rolling out their products next week.
Ryzen 3000 desktop processors -- not to be confused with Ryzen 3000 APUs with are based on 12nm Zen+ Picasso architecture -- are based on 7nm Matisse architecture. While first- and second-generation Ryzen desktop processors topped out with 8 cores, it's expected that Ryzen 3000 desktop processors will be available in 12- and even 16-core versions, which could be a possible reason why third-generation Ryzen Threadripper processors disappeared from AMD's 2019 roadmap.
Alleged benchmarks revealed this week showed a 16-core Ryzen 3000 processor clocked at 4.2GHz (across all cores) getting a Cinebench R15 score of 4276 points. There are also rumors that the 12-core SKU will get a boost clock of 5GHz.
