"Ever since AMD launched Ryzen, the CPU has been selling well — it continues to occupy multiple spots on Amazon’s best-selling CPU list (currently Ryzen chips hold #9, #10, and #15, with the old FX family holding spots #8 and #14, at the time of this writing). Ryzen motherboards, however, have been much more difficult to come by.
As LegitReviews notes (and ExtremeTech confirmed), there aren’t a whole lot of motherboards currently in stock for the platform. The screenshot below is from Newegg and current as of Friday afternoon."
There’s currently a bit of a gap between how AMD has described the desire for its platforms (strong demand!) and why motherboard manufacturers are apparently having such trouble shipping them. LegitReviews has a lengthy quote from an anonymous company that’s worth a read, basically arguing that AMD cut out the motherboard vendors until the last possible second, saying: “They have done nothing they should have been doing to support the launch platform partners and always delay or give no response on support requests.”
This is in-line with what ExtremeTech has heard from various motherboard vendors, many of whom have been frustrated with AMD’s overall approach to this launch. Some of that frustration may be flowing in both directions, but it definitely may be responsible for choking the flow of motherboards into the channel. We had some issues with our own Ryzen launch platform — issues that were both board-specific and out-of-character for motherboard manufacturers at a major launch.
