The quad-core Xeon DP E5405 starts out at $209. The $209 price tag yields a quad-core Xeon DP processor clocked in the 2.0 GHz range, but below 2.33 GHz, with 12MB of L2 cache. Putting forth an extra $47 gets you the quad-core Xeon DP E5410 with its 2.33 GHz clock speed.
That low of a cost for that many cores will be very attractive to small businesses, for sure. The prices quickly scale up from there, Either way, the relatively low power requirements of these CPUs won't go unnoticed either, with even the beefy dual-core 3.33GHz E5260 having a TDP of a mere 65W – clearly showing that the 45nm process has a lot of potential.
These new CPUs are expected at various times over the next year.
