Intel gears up for AMD's Barcelona launch with a slew of new quad-core CPUs
Hot on the heels of the
second generation Intel Core 2 Duo launch
, an internal memo began making the rounds with Intel's 45nm Xeon core frequencies.
These 45nm Xeons, based on the
generation of processors
, also feature the 1333 MHz front-side bus found on the new Core 2 Duo stepping. Each die features 6MB of L2 cache -- giving the two dice quad-core
Xeons a total of 12MB of L2 cache
45nm Quad-Core Xeons
Unlike the desktop roadmap, dual-core Xeons take a more auxiliary role. Intel only laid out plans for three dual-core SKUs at launch; one of which is a low-power CPU. These dual-core 45nm processors, dubbed
, will only consist of a small amount of shipped 45nm Xeon processors.

45nm Dual-Core Xeons
One Intel engineer, who asked to not be named, claimed this focus on quad-core is a typical reaction to the market in general. "In the server space, there isn't much need for dual-core when we can go quad ... If your [applications] are threaded, there's no reason to use two cores when four are available."
Intel did not release pricing on the new Xeons, but comparable 65nm CPUs are expected to get as low as
$266 over the next few weeks
when Intel officially cuts prices on all its existing dual and quad-core processors.
The next-generation AMD
family is expected to directly compete with the Intel 45nm quad-core Xeons. AMD is expected to launch
in the last week of August, with
top-out frequencies of 2.0 GHz

Cache isn't a big power consumer. Infact its one of the lowest power regions of a CPU.
It's also very easy to shutdown cache to save power and there is relatively low leakage current.
