AMD X670 chipset will be a dual-chip design, AM5 platform only supports DDR5
It was reported some time ago that the AMD Ryzen 7000 series based on the Zen 4 architecture has entered the pre-production stage. The new generation of processors codenamed Raphael will use the new AM5 socket (LGA 1718), manufactured using TSMC’s 5nm process, it integrates RDNA 2 architecture core display, supports PCIe 5.0 and dual-channel DDR5 memory. In addition to supporting USB 3.2, the new platform may also have native USB 4.0.
Many players are looking forward to AMD’s new generation of processors, and TomsHardware has also brought some new news. It is said that the AM5 platform only supports DDR5 memory for the time being, and neither the high-end AMD X670 chipset nor the mainstream B650 chipset will provide support for DDR4 memory. However, it is still uncertain whether the memory controllers of the Ryzen 7000 series support DDR4, as low-end A-series chipsets that support DDR4 memory can reduce the installed cost of entry platforms, but it seems unlikely.
With the improvement in the supply of PMIC and VRM, the supply of DDR5 memory has eased, and the price has dropped, but in the future, the price of DDR5 memory is likely to be higher than that of DDR4 memory. Intel’s next-generation Raptor Lake continues the design of Alder Lake in terms of memory type support, continuing to support both DDR4 and DDR5, and the existing 600-series chipsets can also provide support. For the mid-to-low-end market, AMD’s support for only DDR5 memory is likely to be at a disadvantage to the competition.
AMD has chosen to cooperate with ASUS subsidiary ASMedia on the next-generation chipset, and it is rumored to be manufactured using TSMC’s 6nm process. There is news that AMD has adopted the idea of small chips, the X670 is a dual-chip, and the B650 is a single-chip. The B650 chipset connects to the Ryzen 7000 series via four PCIe 4.0 lanes, which itself can provide eight PCIe 4.0 lanes, as well as four SATA ports and multiple USB ports.
There are still doubts about positioning the high-end AMD X670 chipset. New rumors indicate that the X670 platform has two identical chips, but they will not be arranged in the form of north and south bridges and will provide double the scalability of the B650 chipset. AMD’s strategy for the next-generation 600-series chipsets is not the same as the existing 600-series chipsets, and the new solutions are more flexible in design and better control costs.
