No doubt in response to the enourmous success of the Opteron and Dual-Core Opteron, Intel has greatly accelerated the roadmap for the release of the Dual-Core Xeon. Again. The new "Paxville" chips, supporting some new features such as Fully Buffered RAM and upwards of 4MB of combined L2 cache, are set to be here before the end of this year. These CPUs are all EM64T capable and will be working in both newer and older Xeon-based motherboards. However, these aren't all that seperated from their single-core counterparts: They are still power-hungry and hot, and this seems to be mostly a way of Intel making sure they do not lose too much marketshare to AMD while they are still preparing their low-power "Conroe" for both Xeon and Pentium 4.
