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.

ROG Rampage VI Extreme Encore

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

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.

Prime X299-A II

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.

    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.
