We've seen for ourselves just how fast Intel's new Xeon 5500-series processors are. So, what's AMD planning now? The folks at PC World learned from AMD spokespeople that a "very low-power" version of the firm's 45nm quad-core Opteron will be out "within three months."
PC World writes that future low-power Opteron EE processors will "deliver similar performance while drawing significantly less power than [their] predecessors." For the record, AMD's lowest-power 45nm Opterons available today have 55W ACP ratings, and they run at up to 2.3GHz. Their faster brethren have ACP ratings of 75W or 105W and clock speeds as high as 2.9GHz.
The same article also talks a little bit about Istanbul, the upcoming six-core Opteron design. AMD has reiterated its intention to release Istanbul processors in the second half of this year, and PC World writes that the CPUs will find their way into HP and Dell servers. As we learned last month, AMD aims to deliver six-core Opterons with the same power envelopes as current quad-core models.
