According to the site, AMD is working on two Ontario-based "Zacate" processors. The single-core part reportedly has a 18W TDP while the dual-core version uses 25W, and both models feature integrated DX11 graphics. The report from FUD Zilla contains different power specifications, and claims only the dual-core version has integrated graphics.
