K10 that we’ve seen at a few places at the show works at 1.6 GHz and not higher. It looks like the current working revision is stable, cool and great at this particular speed.
If you go any higher you end up with a heath and stability problem and that’s why they needed a new revision that should be ready shortly.
Things are not that great with K10, Barcelona and pushing it back to Q4 won’t help the company’s financial status.
