So how about this as a rumour for a Friday morning? Though AMD will never go on record and confirm this, we have it on good authority that the chip-maker will soon be releasing a super-FX chip. Based on the same 'Vishera' architecture powering the current FX-8350, which runs at up to 4.2GHz, this new FX, codenamed 'Centurion', is to be made available in very limited quantities.

This so-called Centurion is guaranteed to run at 5GHz, on air, though we don't know exactly what voltage or supporting hardware will be required for this lofty speed.
