Not likely, but makes an interesting headline
The Inq reports that a small site purports to have some information on the upcoming Deneb chips.
Apparently Reviewage.co.uk claims that AMD will release an FX-80 and an FX-82 - both Deneb based, with 6MB of L3 cache and unlocked multipliers.
The FX-80 purportedly will run at 4.0GHz, and the FX-82 at 4.4GHz - difficult to believe based on current AMD processor frequencies, but not quite impossible; however the same site also claims that the 4GHz FX-80 will outperform a 5GHz Kentsfield, which would make it roughly equivalent to a 4GHz Penryn.
They have some slides, and I hope this is true... however, I am definitely not holding my breath.
