Zen was a big step up from AMD’s Bulldozer architecture and it’s only getting better with revisions. Ryzen’s first series was released in 2017 and it really brought the spotlight on AMD. The company stuck with its high core count philosophy, but they did make massive improvements in performance per core. Memory compatibility has been an issue with Ryzen but it got considerably better with last year’s Ryzen 2. With Ryzen 3 AMD will stick to its tried and tested formula and we will get good IPC improvements, higher core counts and even better memory compatibility.
More Details On Memory Support

This has been confirmed by two very reliable sources. Ryzen 3000 will have 3200 MHz DDR4 RAM support right out of the box. Including support for “DDR4 4400+(OC) / 4300(OC) / 4266(OC) / 4200(OC) / 4133(OC) / 3466(OC) / 3200 / 2933 / 2667 / 2400 / 2133 ECC & non-ECC, un-buffered memory“. Ryzen 2 officially maxed out at 2933Mhz, but you could push 3600MHz with some chips. Here the OC limit ceiling is placed at 4400+ MHz and that’s crazy fast, obviously, that limit is subject to the motherboard and chip combo.
Recently we covered a leaked x570 motherboard from Biostar, stating “Up to 64gb of RAM is supported on the four RAM slots and the best part is that the DDR4 RAM speed cap is at 4000 Mhz. We did know Ryzen 3000 was going to support faster RAM and 4000 Mhz is a good step up from the previous cap. Higher-end boards will probably cross the 4000 Mhz mark.” These improvements can be attributed to improved memory controllers in the chip. Zen architecture loves fast low latency RAM which benefits data and control transmissions across cores.
RAM Support Will Also Depend On Motherboards
Most x470 boards supported higher memory speeds when compared to B450 boards, due to thicker PCBs. We will see similar trends with x570 and B550 boards. Many of the leaked x570 boards have active cooling on their PCH, this is reportedly due to the extra heat generated by higher signaling rates in PCle 4.0. This is something all x470 boards lack, although faster memory support can also play a part here.
AMD is all set for a reveal in Computex which is at the end of this month, so we only confirm these numbers then.
