AMD X670E (Extreme) chipset will support PCIe Gen5 for GPU and storage
AMD CEO Dr. LiSa Su will give a keynote speech at the Taipei Computer Show on May 23, and at this time they are likely to officially announce the Zen 4 architecture Ryzen 7000 series processors. The new processor will use the AM5 platform instead, will support PCI-E 5.0 and DDR5 memory, and the interface of the processor will also be changed from Socket to LGA.
The new platform also needs a new chipset to work with. According to videocardz, AMD will announce the X670, X670E, and B650 chipsets at the Taipei Computer Show. In fact, it has been reported that the X670 is a dual-chip, while the B650 is a single-chip. The new chipset is produced by TSMC’s 6nm process.
Of course, the name X670E only appeared this time. It is the Extreme version of X670. AMD X670E will be forced to support PCI-E 5.0, including the slot connected to GPU and M.2 NVMe SSD may support PCI-E 5.0. The X670 does not have a mandatory requirement. It can only support PCI-E 4.0. In addition, there is no functional difference between the two chipsets. As for the memory, if there is no accident, the processor of Zen 4 only has a DDR5 memory controller, so no matter which chipset, you have to use DDR5 memory.
The FCH chip codenamed by ASMedia for AMD’s next-generation platform is Promontory 21, of which the B650 uses one, and the X670/X670E uses two. According to previous news, the chip uses PCI-E 4.0 x4 to connect to the Zen 4 processor, providing 8 PCI-E 4.0 channels and 4 SATA ports, and the number of USB interfaces is unknown.
