During the Computex 2022 keynote today, AMD announced the X670E, X670 and B650 chipsets. AMD announced the B650E chipset, the fourth chipset for the Ryzen 7000. The B650E chipset will be sold alongside the already announced B650 chipset, but since it is part of AMD’s “Extreme” family of chipsets, it will have features not available on the standard B650, such as support for PCIe 5.0 lanes in at least one M.2 slot.

During AMD’s keynote at Computex 2022, AMD CEO Steve Su introduced three AM5 chipsets to better leverage the power of the 5nm Zen 4 core in the Ryzen 7000 processor. We already know that the AM5 socket is based on a channel grid array (LGA) socket with 1718 pins, aptly named LGA1718. Some of the significant benefits AM5 brings include native PCIe 5.0 support for CPUs, not only for PCIe slots but also for PCIe 5.0 storage, with the first consumer drives expected to be available starting in November 2022. The first consumer drives are expected to be available starting in November 2022.

AMD’s newly announced B650E (Extreme) chipset offers motherboard vendors and users a choice of low-cost platforms without sacrificing PCIe 5.0 longevity and expansion support. The X670E chipset is reserved for its most advanced models, such as the flagship ASUS ROG Crosshair X670E Extreme motherboard unveiled at Computex 2022.

Using PCIe 5.0 lanes requires a higher quality PCB, often with more layers to allow the alignment to maintain signal integrity, but this typically increases cost. The presence of the B650E chipset will allow vendors to offset costs by enabling the use of more expensive PCIe 5.0 lanes and more modest controller sets. Ideally, it provides users with a broader, more future-proof upgrade platform without spending a lot of money on unnecessary controller sets; those who want the best controller set should choose the X670 or X670E.

As previously revealed in the news, the AMD B650E chipset and X670E positioning, although different, but are the main “Extreme”, can support dual PCIe Gen5 protocol for graphics and storage. For the non-E series, the X670 and B650 will only support one of the graphics or storage (PCIe slots or M.2 slots to be exact).

Unlike the X670 series, the B650E will come with a Promontory 21 chipset that will shrink the number of PCIe lanes.

While AMD was previously rumored to be working on another B650 chipset, the Extreme model has only appeared in leaks so far. This new PPT finally confirms that AMD is indeed bringing at least four different chipsets to its AM5 platform.

Later today, AMD will announce new details on its Ryzen 7000 series and possibly on the AM5 platform itself, though the B650 motherboard is not expected to debut next month, but rather a bit later than the other three series.

The new AMD Socket AM5 platform features a new 1718-pin LGA design that supports processors with up to 170W TDP, dual-channel DDR5 memory and new SVI3 power infrastructure. AMD Socket AM5 also features PCIe 5.0 lanes with up to 24 of them.

According to AMD’s official website, the AM5 series motherboards are divided into three main series: ・ X670 Extreme: Provides PCIe5.0 support for two graphics slots and one memory slot.

・X670 Extreme: PCIe5.0 support for two graphics slots and one memory slot, bringing powerful connectivity and higher overclocking performance

・X670: PCIe5.0 support for one memory slot and one graphics slot (with PCIe5.0 support for the graphics slot optional), designed for enthusiast overclockers

・B650: With PCIe 5.0 support for memory slots, designed for high-performance users.
