45nm Xeon Clock Frequencies Leaked By Intel

The new batch of 45nm Xeons is actually based on the Penryn processor and also feature the 1333 MHz front-side bus found on the new Core 2 Duo stepping. Each die features 6MB of L2 cache resulting in a total of 12MB of L2 cache.
The latest 45nm Xeon ( Codename HarperTown ) Quad Core line is as follows

X5640 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 2.10 GHz 80W 1333 MHz 12MB
L5430 2.66 GHz 50W 1333 MHz 12MB
L5410 2.33 GHz 50W 1333 MHz 12MB

While the Dual Core 45nm Xeons ( Codenamed WolfDale ) are

E5260 3.33 GHz 65W 1333 MHz 6MB
E5205 1.86 GHz 65W 1066 MHz 6MB
L5250 3.16 GHz 40W 1333 MHz 6MBSource: Intel


Ps : Its Quad Cores people....All sites around the net made the same mistake and corrected it so sorry for the mixup :)

All this news today is just overwhelming. I wasn't under the impression that they were doing much with single cores anymore, whats the benefit for a server to be single core? Also the 40W TDP is quite impressive on the L5250, I guess thats the 45nm for you.

These XEONS are beasts so even a single core aint something to laugh at :)

TDP to core and cache to core ratios do not compute, I think you listed them the wrong way round ;)

Edit:
What I want to know is whether they have SSE 4.1 included. I presume they do ...

Wait I don't understand. If each core has 6MB of cache, then why do the single cores have 12MB and the dual cores only 6MB? Shouldn't that be reversed?

I think its 2dies x 6mb for the single core cpus...Couldnt find more info on them so far.

do you mean single core, or single cpu? if it's the former, that doesn't make much sense, considering a die shrink shouldn't increase TDP's.

Harpertowns are the 45nm Xeon's based on the Penryn design, I think. This would account for the higher TDP numbers.

6mb for a single core?!?!? i think they were talking about 6mb per die (aka two cores)....also, i think the top things that are "single core" look as if they should be quad cores, while the bottom except for the 40 watt tpu are dual core while the 40 watt tpu is single core. that's what i think anyways....

Sorry, I meant to say that the processors labeled "single core" should be "quad core" as they are the Harpertowns. Intel is focusing a lot more on the quads in the server market.

Yeah, I thought both companies were mostly done with single core chips. Ah well, these look rather impressive.

Its quad cores and dual cores...Mixup people sorry :)
