AMD X570-efterfølger til tredjepart



AMD X570 chipset is the industry's first PC platform core-logic to support PCI-Express gen 4.0, but has proven to be expensive and hot. Its 600-series chipset successor will be third-party sourced much like its 400-series predecessor, according to a MyDrivers report citing sources in the motherboard industry. AMD is reportedly sourcing its 500-series mid-range chipset, the B550, from ASMedia. The B550 uses PCI-Express 3.0 x4 as its chipset bus, and puts out eight PCIe gen 3.0 downstream general purpose lanes, however, B550 motherboards could still feature PCI-Express 4.0 x16 slots from the socket AM4 SoC (provided a 3rd gen Ryzen processor is installed), and at least one of the M.2 NVMe slots on B550 motherboards could have PCI-Express 4.0 x4, since they're wired to the SoC instead of the chipset.

MyDrivers-rapporten forudsiger, at efterfølgeren til X570, den formodede 'X670', kunne hentes fra et tredjepartsfirma, ligesom B550, og implementere PCI-Express gen 4.0, ikke bare som chipset-bus, men også udlægge PCI-Express gen 4.0-generelle baner. Et muligt designmål for X670 kunne være at implementere PCIe gen 4.0-skiftestof uden at køre for varmt, hvilket resulterer i et køligere chipset, end det kan gøre med fanless køleopløsninger, ligesom X470. AMD vil fortsætte med at fremstille 'chipsets' i form af I / O-controller-matricer til brug i sine MCM-processorer, selvom den relativt lille margin-chipset-forretning kunne styres.
