(badly) translated from French. Macbidouille were the first to get all the G5 PPC 970 info a year before it's release. They have a very good hardware connection somewhere and are usually reliable: Why switching to INTEL - Lionel - 12:13:26 - [...]We do it, because the information that we deliver to you belongs now to a recent past, and that it will make more comprehensible that the abandonment of the Power PC is not a whim on behalf of APPLE, but a vital need. Since the end of the year all hell broke loose between APPLE and IBM which is again qualified of a Motorola by Steve Jobs. IBM had great hopes for the famous PPC 975 976 then 980 but which is unceasingly delayed. The 970MP was inserted to face these delays. But it would have arrived in the best of the cases only at the beginning of 2006, whereas they do not even manage to produce in great quantity the PPC 970FX. For Powerbook G5 all the developments were at the dead point. Impossible to manage to manufacture a 970GX able to satisfy the needs for portability. Impossible to obtain an acceptable autonomy and an effective cooling. IBM also decided to give up the project of PPC 750VX which was intended to replace of G4 in the entry level machines. APPLE, like Steve Jobs said, had envisaged this possibility and had kept in its sleeve the INTEL card. In front of the incapacity of IBM to advance, they activated the Maklar project of which we start to see the extent. Our source largely reassured us on the future, because the current roadmapl seems planned for many years. But we leave that to other (real) rumour sites to tell you all that one day or the other. For this kind of information, our engagements to no longer publish rumor son forthcoming products always hold. Macbidouille were the ones to reaveal that both the 2.5GHz and 2.7Ghz PowerMacs were overclocked 2.2 & 2.3Ghz G5's: 2004-08-24 - G5 2.5 overclocked- G5 dual-2.5 GHz currently delivered were initially manufactured at 2.2 GHz. It was thus necessary of the watercool the system in order to make them stable at this higher clock speed.
