(EDITED) Doug, I've read a while back that Nehalem will only be quad (not octal) core on 45nm because the on die mem contr + csi logic takes space as well. Do you have any information to the contrary? BTW, Groo in April thought Nehalem would be end 2008 / start 2009: aceshardware.com And: second half of 2008, we will be introducing a new micro architecture on 45 nm, Nehalem [as replacement of the Merom core family]: tgdaily.com (As you know H2 usually means Q4 in this industry - of course there are always exceptions) Anyways, that's how I remembered it as well: First Tukwila, then Nehalem. The info is a bit dated and partly indirect, plus I haven't read up all info on it. So I'd appreciate it if you could show this wrong. Considering performance by end 2008 Nehalem will have a reworked core, but Fusion will have ATI's logic (there might be more that we don't know about yet). You seem so sure Nehalem will win from Fusion, or from possible Octal cores from AMD (remember Fusion is a modular concept one version of which might be without the ATI module which in turn might enable octal core - I know it's speculation but at least it makes sense to me, plus the info about Fusion being modular was shown on a recent slide that was discussed here. Unfortunately I can't find back the slide I have in mind). My questions are what is the basis of your apparent conclusion that Nehalem will be better than Fusion, and secondly why you think Nehalem will arrive a long time before Fusion? Tx, Rink reghardware.co.uk EDIT: Some findings: Tukwila tape out early 2008: theinquirer.net Tukwila is supposed to be 65nm. As far as I could find Nehalem will be Intel's first native quad core. Nehalem could have as much as 8 CSI links: theinquirer.net EDIT2: Some more findings: Nehalem according to several articles will have hyperthreading again (8 threads on 4 cores). vr-zone.com Socket B will be LGA1366 and Socket H will be LGA715. The reason why Socket B has so many more contact pads is pretty obvious. It is due to the IMC on the Nehalem CPU. Since there is a Socket H version as well, we can expect there will be another Nehalem based CPUs without IMC.: vr-zone.com 65nm 'Core' 45nm 'Core' 45nm 'Nehalem' 2006 2007 2008 Server Tigerton Aliceton Beckton Clovertown Harpertown Gainstown Woodcrest Desktop Kentsfield Yorkfield Bloomfield Conroe Wolfdale Notebook Merom Penryn Gilo http://tweakers.net/nieuws/45272/HyperThreading-keert-terug-in-2008.html Lastly for laughs: 10.20GHz Intel Nehalem slated for 2005: theinquirer.net
