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 Penryn 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 Harpertown Xeons a total of 12MB of L2 cache.

45nm Quad-Core Xeons
Model	Core Frequency	TDP	FSB	L2 Cache
X5460	3.16 GHz	120W	1333 MHz	12MB
E5450	3.00 GHz	80W	1333 MHz	12MB
E5440	2.83 GHz	80W	1333 MHz	12MB
E5430	2.66 GHz	80W	1333 MHz	12MB
E5420	2.50 GHz	80W	1333 MHz	12MB
E5410	2.33 GHz	80W	1333 MHz	12MB
E5405	???	80W	???	12MB
L5430	2.66 GHz	50W	1333 MHz	12MB
L5410	2.33 GHz	50W	1333 MHz	12MB

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 Wolfdale, will only consist of a small amount of shipped 45nm Xeon processors.

Intel also uses the Wolfdale codename to describe dual-core 45nm desktop offerings.

45nm Dual-Core Xeons
Model	Core Frequency	TDP	FSB	L2 Cache
E5260	3.33 GHz	65W	1333 MHz	6MB
E5205	1.86 GHz	65W	1066 MHz	6MB
L5250	3.16 GHz	40W	1333 MHz	6MB

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 Barcelona family is expected to directly compete with the Intel 45nm quad-core Xeons. AMD is expected to launch Barcelona in the last week of August, with top-out frequencies of 2.0 GHz.

RE: TDP means different things to different companies.

What's wrong with a little bit of legal disclaimer in the datasheet? Worst case conditions aren't nominal operating conditions under full load. No, that's what the TDP represents. Worst case conditions where the processor will dissipate more than the TDP is when you have a 'slow silicon' processor with motherboard VRM that's at the top end of the tolerated voltage margin - extra voltage on a 'slow' part means more heat.

Heh, it's easy to make a processor dissipate more heat than the TDP dictates it should...
