I am a little confused. Me and wife just got back from 2 weeks in Hawaii so I am trying to catch up. I read an article before I left that said the Penryn would be 2 seperate dies as is kentsfield . But all the cache would be shared on both dies.
Since this info comes from VR zone . Which is less reliable than the inquirer I think we need more info.
I am still looking for the link but here's some interesting reading.

From above link . Native quad core in 2007
Intel was originally expected to launch dual-core Wolfdale (for desktops) and dual-core Penryn (for laptops) processors made using 45nm process technology in 2008, according to earlier information. However, considering the recent progress with 65nm product shipments and ongoing progress with 45nm development, the company seemingly speeds up its roadmap. In addition to 45nm dual-core chips in 2007, there are rumours about single-die quad-core chip made using 45nm process technology in the Q3 2007.

Now if you look at VRzones report it says 50 new sse4 instructions . If you read more reliable sources you will see that the (penryn wolfdale cpu's will only recieve 30 new instructions and the latter nehalem will use 50 instuctions from sse4 .
So what most are saying is 12mb. of shared cache= 3mb per core or 1 core can use all 12 mb of cache. Also most reports are saying that yorksfield will be a native 4core cpu. Wolfdale will be the dual core model clocked at 4ghz with 6mb of shared cache.
You add in the 30 sse4 instructions aong with the high k gates (metal ) and the higher clocked speeds the wolfdale should be 75% faster than Conroe.
Isn't it amazing . The big question is who is out of the gate first. Wolfdale/ yorksfield or K8L(K9). My guess is the the K9 doggy will be first but will be no match for the Wolf/ yorksfield.
Intel is really turning on the heat. In 2008 we get nehalem . Man I don't want to ever piss Intel off.
