AM5 platform gets three chipsets with differences in PCIe 5.0 support – Computer – News

Three chipsets will be available for AM5 motherboards coming out this fall. In addition to the B650 and X670 chipsets, which follow the B550 and X570, there will also be a “high-end” X670E chipset, with maximum PCI Express 5.0 support.

David McAfee, director of AMD’s desktop division, said AM5 motherboard chipsets differ primarily in their support for PCI Express 5.0. During the keyword in Computex From the company. The overall platform can provide a total of 24 PCIe 5.0 lanes, possibly 16 video card lanes, four M.2 lanes and four more for chipset connectivity. The more luxurious X670E chipset, where E stands for “Extreme,” can offer two video card slots and one M.2 slot for an SSD drive with PCIe 5.0 bandwidth. With the B650, the SSD only runs at PCIe 5.0 speed.

Currently, there are no video cards or hard drives for sale to consumers who support PCI Express 5.0. It’s not yet clear if next-generation video cards will benefit from this, but AMD wants to end the PCIe 5.0 SSD shortage by working with console designer Phison and memory manufacturer Micron. Many brands will be around the launch Ryzen 7000 CPUs An SSD based on those third-party hardware launches in the fall, with sequential read speeds over 60 percent faster than existing PCIe 4.0 SSDs.

Socket AM5 refers to switching from pins to processor for AMD (s) to the pins in the socket (lga), as Intel has been using it for years. The AM5 socket has 1,718 teeth, which raises the power and signal integrity level above what the AM4 can. The socket can handle CPUs with a TDP of 170W. Thanks to heat spreaders with a fairly typical appearance for Ryzen 7000 CPUs, compatibility with AM4 CPU coolers is maintained.

All AM5 socket motherboards get DDR5 slots; The memory controller in Ryzen 7000 processors is not DDR4 compatible. Motherboards also get a maximum of four connections to the monitors, because the new CPUs are all equipped with RDNA 2-igpu. Both HDMI 2.1 and DisplayPort 2 can be used. Moreover, manufacturers can supply their motherboards with Wi-Fi 6E via a controller that AMD has teamed with MediaTek for.

Unlike Ryzen 6000 laptop processors, Ryzen 7000 desktop models will not support USB4. There will be a maximum of fourteen USB ports of the platform, a limited number of which can reach 20 Gbit / s. The USB4 Ports for AMD Laptop Processors Get 40 Gbit / sec.

Like Ryzen 7000 processors AM5 motherboards based on the B650, X670, and X670E chipsets will also hit the market in the fall. AMD has already showcased the best X670E models from ASRock, ASUS, Biostar, Gigabyte and MSI. Prices have not yet been announced.
