Leaked AMD 600-series mobo specs lack PCIe 5.0 assist

A leaked block diagram that appears to originate from the Gigabyte ransomware assault, seems to point out the AMD 600-series motherboard chipset will not assist PCIe 5.0 (through TechPowerUp). That is the chipset that’s designed to assist Zen 4 processors, anticipated to launch in 2022. 

Intel, in the meantime, has confirmed this week at its Structure Day 2021 that its Alder Lake hybrid processors will assist PCI Specific 5.0. It will give Intel the lead in relation to superfast storage and probably graphics playing cards too, though the latter is a little more of a leap.

It is a notable swap from the lead that AMD loved with PCIe 4.0 for nearly two years since its Zen 2-powered Ryzen 3000-series landed. Intel solely supplied assist for PCIe 4.0 with its Eleventh-gen Rocket Lake chips, which launched in March this yr.

The principle good thing about shifting over to PCIe 4.0 has been on the storage entrance, the place the bandwidth doubling over PCIe 3.0 will be utilised. In case you are questioning, graphics playing cards have proven no notable profit working on PCIe 4.0, no less than not in relation to precise video games—though there are artificial exams that present there’s potential there too. 

The quickest PCIe 4.0 SSDs have been pushing up in opposition to the boundaries of PCIe 4.0 although, with sequential reads of seven,400MB/s from the likes of the Adata XPG Gammix S70 2TB SSD. The bandwidth doubles once more going to PCIe 5.0, which ought to give SSD producers loads of room for the elevated sequential throughput.

If this seems to be true, does that imply that AMD might be left behind? Most likely not. Whereas Intel might win a couple of headline battles on the best way, the reality is the precise day-to-day efficiency of the quickest SSDs remains to be a good distance off the boundaries of PCIe 4.0. Even with Zen 4 not anticipated to launch till subsequent yr, AMD ought to nonetheless be aggressive. And that is bearing in mind any magic that DirectStorage can convey to the social gathering.

There’s not rather a lot else of notice from the block diagram, apart from there are 4 extra PCIe lanes that feed straight to the discreet USB4 controller, and that the rumours about AMD supporting DisplayPort 2.0 appear to be right. DDR5 assist is current and proper too, though there is no indication of how briskly it is working. 

As ever, these are simply rumours at this level and many might change by the point Zen 4 truly launches. Even so, the good thing about shifting over to PCIe 5.0 will not be fairly as urgent because the final generational improve was. With Alder Lake as a result of launch earlier than the yr’s out although, we might quickly discover out a technique or one other.
