Ashlee Vance covered the Barcelona launch yesterday, of course, but his piece had two interesting bits of tid I hadn’t seen before. First, in the “fight fire with fire” department, AMD is changing the way it measures power
AMD has shifted to the average power measurement in the hopes of presenting “apples to apples” comparisons with Intel. AMD has tended to give maximum power consumption figures in the past – usually only attainable in the labs – and chastised Intel for giving average power consumption figures. In addition, Intel tends to leave out the power consumption issues it faces from things such as FB-DIMMs.
And thence on to the next processor bump, octacore* chips
AMD, of course, also has a 45nm four-core follow-on to Barcelona called Shanghai set for 2008. Then the company should follow with a pair of octal core chips in 2009, according to Pat Patla, director of AMD’s server and workstation business. So far, AMD has confirmed the latter chip as running on a new “Sandtiger” core but has yet to release a code-name for the earlier octal-core part.
* N.B.: Ashlee actually used the term “octal core.” I’ve also seen “octal-core.” Both of these strike me as awkward. I hereby create a new term, “octacore,” and will use it with wanton abandon when writing about the next generation of chips. Also, I’m going with quadcore from now on (not quad core or quad-core or Quad Core). Just so you know.
