ASUS B660 Leak Hints Mainstream Alder Lake Motherboards Might Not Help PCIe Gen 5


ASUS Motherboard
The one chipset that is been introduced for Intel’s twelfth Gen Core Alder Lake processors to this point is Z690. Intel is getting issues began on the high-end, with Z690 supporting all of the newfangled applied sciences that Alder Lake is embracing, and particularly DDR5 reminiscence and PCI Categorical 5.0. However what about the remainder of the stack? It is potential that Intel’s extra mainstream chipsets will persist with PCI Categorical 4.0 for one more spherical.

Nothing is for sure, however assuming Intel follows its personal precedent, at minimal there might be H670, B660, and H610 chipsets added to the combination to handle the house client market. What makes this can be a distinctive launch that leaves some issues as much as guesswork is that Alder Lake is a serious shift in design, with a number of know-how upgrades coming alongside for the experience.

This is the place issues get fascinating. The parents at Videocardz posted a photograph of an ASUS Prime B660-Plus D4 motherboard label, and it clearly signifies PCIe Gen 4 as a substitute of PCIe Gen 5. Take a look…

Because the story goes, an unnamed reviewer acquired a Z690 motherboard from ASUS, however it was purportedly shipped within the unsuitable packaging. In doing so, ASUS might have tipped Intel’s hand for what’s in retailer for its mainstream B660 and entry-level H610 chipsets, neither of which have been introduced. If the packaging label is correct, a number of doubtless each with both not assist PCIe Gen 5, or optionally assist it.

This may be one thing that’s distinctive to ASUS, or the sticker may very well be from an early prototype. It may be a typo, or perhaps a hoax. That is to say, do not carve it in stone that mainstream Alder Lake motherboards won’t make the leap to PCIe Gen 5.

What additionally makes this fascinating is that Alder Lake desktop CPUs provide 16 lanes of PCI Gen 5 (and 4 lanes of PCIe Gen 4) proper off the foundation CPU advanced, not the PCH (Platform Controller Hub), which itself throws one other 28 lanes of PCIe 4 and PCIe 3 into the equation.

This raises the query of why mainstream and entry-level chipsets would not assist PCIe 5, and assuming that is even correct, the reply is perhaps that it is no huge deal. It nonetheless stays to be seen what precise efficiency advantages customers will glean from PCIe 5, because the PCIe bus hasn’t precisely been a bottleneck for gaming GPUs, and PCIe 4 SSDs like Samsung’s 980 Professional are extremely quick already.
Regardless, this may very well be a separating issue between Z690 and chipsets that sit additional down the steps. it can even be fascinating to see what Intel has in retailer for its mid-range H670 chipset—we assume it can assist PCIe Gen 5, however solely Intel is aware of for positive. For now, the leaked ASUS B660 label raises extra questions than it solutions.
