A source of Xbitlabs has responded to recent rumours that claim AMD’s first Fusion APU, Ontario, will have a TDP of 18W or even 25W for the dual core. The source, said to be close to AMD, has stated that categorizing Ontario as “18W or 25W is not reasonable and well outside the margin of error”. The exact power consumption was not mentioned but it is reported to be well below the rumoured figures of 18/25W.

A source of Xbitlabs has responded to recent rumours that claim AMD’s first Fusion APU, Ontario, will have a TDP of 18W or even 25W for the dual core. The source, said to be close to AMD, has stated that categorizing Ontario as “18W or 25W is not reasonable and well outside the margin of error”. The exact power consumption was not mentioned but it is reported to be well below the rumoured figures of 18/25W.

The recent 25W rumours relate to a Fusion part codenamed “Zacate”, which has been widely associated to be an Ontario based APU. However, Ontario has long been described as a “1W to 10W” part, with some variants ending up at sub-1W and capable of powering ultraportable devices beyond netbooks. The 25W part is clearly not Ontario that will find its way into mobile devices under the Brazos platform. Further suggestions have been made to this 18W-25W Zacate part being higher clocked desktop versions of Ontario. Or, it could be  low-power Llano APUs or Llano designed for full sized notebooks, as part of the Sabine platform.

With a release to OEM expected late this year, and netbooks and other devices featuring Ontario releasing early in 2011, there are still conflicting rumours and confusion surrounding AMD’s Ontario. Indeed, it is possible that the rumoured “Zacate” has nothing to do with Ontario at all. For now, we have to take everything as rumours/speculation, and await further details.
