ATI-Forum.de have uncovered details about AMD's upcoming Fusion APUs. The first products, codenamed "Zacate", will be single-core and dual-core APUs with 18W And 25W respectively. Zacate is a codename that has been previously rumoured - and assumed to be Ontario. Ontario was previously announced to be operating in the 1W to 10W range, though this could be the CPU's TDP only, and the 25W might be the TDP for the top model including the entire APU System-On-Chip (including the GPU). Alternatively, it could also be a low-power variant of Llano, which is a 10W-100W APU.

Zacate could also be the desktop version of Ontario - with higher clocks pushing the TDP up. Whether Zacate is Ontario remains to be seen. We know that Ontario will be fabricated at 40nm Bulk, so the mention of 32nm further complicates things. Even if the rumoured Zacate is Ontario, there may be low-power versions of Zacate designed for netbooks and ultraportables, which might bring the TDP down to promised levels of sub-10W. The release is likely to be in December 2010.

Mainstream Fusion - Llano - is still scheduled to release in Q1 2011. There was talk of squeezing in a release in 2010, but due to issues with the Globalfoundries 32nm process, Llano will now firmly release in Q1 2011.

ATI-Forum.de have also revealed an updated Roadmap. This roadmap remains much the same to the one we revealed back in April. A key addition is the Phenom II X6 1045T, which will be released in the $175-$200 market in Q3 2010.
