Intel Ships Core Duo-based Xeon 45
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?"

I'm looking forward to AMDs response to these impressive (at least in the preview) chips.

Its faster than fastest opteron on perl and circuit layout part of spec int. And looses badly on chess
In overall its EQUAL to fastest dual core opteron on spec int.
The fact remains that FSB is just ONE variable in huge nets of variables in performance equation.
Using more cache means less memory accesses outside chip, using better prefetcher, helps memory access and soon, the off die memory accesses take such a small fraction of time, on MOST software that ondie memory controller vs FSB becomes non issue. [The percentage of improvement from ondie becomes less important than being flexible at new memory technologies on old sockets.]
And memory accesses only take part of the time that must be improved other part is improving core, which part is often more important than improving the offchip memory accesses when there is enough cache. [depends on code].
Take one thing that competitor can potentially do some what faster means nothing if you separate it from all the other aspects of CPU.

These are low-power chips that are based on the laptop models. The real "Core" Xeons are coming in a few months and will have a bus at double that (IIRC).

Until they kill the current xeon line and get rid of the inventory on stock they will keep this chip under a tight noose, only ramping it up as they feel the need.
