With all the excitement surrounding AMD’s “Atom-killing” processor that is so strongly rumoured to be announced tomorrow at the company’s analyst conference, the expectation is that it will be the “Bobcat”, AMD’s UMPC-oriented processor. Intel is likely to be shaking in its boots ahead of this press conference, as the low-power CPU, should it be announced, could finally topple its Atom processor that is so dominant in netbooks.

The Bobcat is speculated to feature 64-bit 1GHz core and consume eight watts of power. This would actually be more than Atom’s usage, but the Bobcat is expected to also have an on-chip memory controller that would reduce power consumption elsewhere in the machine.

Another rumour is that AMD could also announce plans for its UVC (Ultra-Value Client), a series of dual-core chips that run around 1.6GHz, although the higher power requirements could mean they run on nettops and not portable devices.

Tomorrow is the day when we’ll know for sure what AMD has up its sleeve, and we’ll have an update here as soon as concrete information is available.
