Intel Ships Core Duo-based Xeon
diegocgteleline.es writes "According to The Register, Intel has begun shipping a power-efficient dual-core "Xeon LV" and claims that it consumes no more than 31 W running at 2 Ghz, with a 667 Mhz frontside bus and sharing 2 MB of L2 between the two cores. The new chip has "four times the performance-per-Watt of its existing 2.8GHz LV Xeon CPU", not surprising given how slow and power inefficient those CPUs were. While this looks like a move to make AMD shares continue yesterday's tendency, it looks like Intel is starting to catching up?"
The inevitable Woodcrest-based Xserves should satisfy those people who only care about performance. Or they could just buy Opteron servers today.
The article specifies a TDP of 31W, a total of 2 MB cache (1M per core), 667 MHz FSB, and a clock speed of 2.0 GHz.
How is this different from the Core Duo T2500? From the looks of it, there is none.
retrorocket.o not found, launch anyway?
The whole reason people buy clusters instead of a specially built system like Cray's is for the cost. Running a large (hundreds of nodes) cluster costs upwards of tens of thousands a year for electricity and cooling. Energy efficiency is definitely warranted in this case. It's the same reason IBM's BlueGene employs 700 MHz PowerPC processors. http://en.wikipedia.org/wiki/Blue_Gene
Alternately, apple put pressure for a chip that they can use to put in a new "core quad" (ie 2 of these) power mac to be announced 1 Apr? Timing's right ... (intel announces this 2 weeks before 1 Apr) ... Hmmmmm.
At least this quad monster won't have to be water cooled.
