X570 IN SHORT SUPPLY

Looking over the supply of MSI X570 motherboards at NewEgg, I was surprised to see most model boards are not available. It seems that there is anticipation of a new high-end chipset for the launch of the Ryzen 4000 series processors.

My MSI X570-A PRO is a good basic platform for AM4 and PCIe 4.0 support. This allows for several years of improvements for storage and 4K gaming.

According to the Chinese site MyDrivers, the X670 chipset will not be designed by AMD but will be outsourced to ASMedia or Via. AMD had to develop the X570 chipset in-house as the traditional vendors did not have the expertise to design a PCI Express 4-compatible chipset. With AMD showing how it’s done, this is not going to be a problem next year and once again, partners will be taking over X670 production. This should also benefit AMD as apparently, selling chipsets does not really help with the company’s profits. The exact features of X670 are still unknown, but it is expected to improve PCIe Gen4 implementation and offer more connectivity for NVMe, SATA, and USB 3.2. Thunderbolt 3 integration is still not on the cards as per the report. 

TSMC N7+ has identical yield rates to N7 which will steadily improve, while also offering a 20% increase to transistor density. There’s also a 10% performance uplift or 15% power efficiency increase. The 20% increase in density could bump up L3 caches slightly.

ASMedia appears to have a contract for the design of B550 and A520 mainstream and entry-level motherboards. This suggests X670 may be made by them as well. ASMedia has finally managed to modernize to PCIe 4.0 speeds.

Besides X670 there is also the B550 which is now slowly ramping up. The B550 will also be limited to Ryzen 3000 and Ryzen 4000 processors for PCIe 4.0 support.

The X670 will likely be present at the same time as the new processors are released. This board and the Ryzen 4000 processors are the last for the PCIe 4.0 platform and socket AM4. AMD is now preparing for the transition to DDR5 and PCIe 5.0.
