Asus Readies for Next-Gen Intel HEDT With Three New X299 Motherboards

Following up on recent news of leaked benchmark data, Asus has announced that it’s already prepared a trio of X299 motherboards to support Intel's next-gen HEDT Cascade Lake-X CPUs. Or maybe that’s some other next-gen CPU? You be the judge. But there's no denying the details of these new HEDT boards.

The “EATX”-specified ROG Rampage VI Extreme Encore gets top billing (cough, or at least an encore) with its 16 power “stages,” 1.77-inch LiveDash OLED display, 10GbE controller, four NVMe M.2 slots, and 20Gbps Gen2x2 USB3 header. Of course, the board is also packed with other high-end ROG features, such as coolant flow and temperature sensors, but that’s covered in the features table below.

ROG Strix X299-E Gaming II assumes the center, getting no encore for its Roman Numerals. It does, however, get most of the features of its big brother, substituting 2.5GbE for the higher-speed variant, dropping down to three NVMe M.2 slots and a 12 “stage” CPU voltage regulator, and losing the flow rate and temperatures sensors. But, it fits within the standard ATX form factor and even gains an x4 slot to replace the fourth M.2 slot that it lost.

For those of us who need to save a little money to buy that new CPU, Asus offers its Prime X299-A II. It has but one Gigabit Ethernet controller, no Wi-Fi, three NVMe M.2 connectors, and two x1 slots to supplement the x16/x16/x8 configuration of its longer slots. Hey, at least it has the same voltage regulator as the Strix version.

Availability and pricing have not been announced, but we expect these to coincide to the release of Intel’s next-generation X-series CPU and to cost a little more than the models they replace.

    Still no 10gig Ethernet?

    It says 10GbE for the top board, are you looking for it on a cheaper board?

    Ehh, Youd think theyd open up 10 gig slightly more. Maybe another generation or 2.

    That board is EATX. That's my beef with it. I have an ATX case that I'd want to reuse.

    But, I'm looking towards the next ThreadRipper, anyhow.

    BTW, the article doesn't list the socket type. I assume LGA 2066?

    It probably isn't really EATX, it's probably only XL-ATX depth (10.6/10.7 inches). Most good ATX cases have an extra inch of space in front of a 9.6" board anyway.
