In FP it looks relatively competitive but if the Integer performance is even close to what is realized this would be very bad news for Shanghai, with Nehalem having a 40% lead (looks like about 2 for SH versus 2.85ish for Nehalem).

Working the numbers for Nehalem I get about 164/167 for SPECint/fp_rate_base2006 (assuming two socket configurations, which seems to fit with the relative numbers).
Current top of the line Harpertown is at 121/80.4, while the (now invalidated) 2.5 GHz Barcelona submissions were 102/86.3. It looks like Intel/Sun are expecting a 2.8 GHz Shanghai to come in at about 122/126.
Edit: switched int/fp for Barcelona. Also those are peak numbers, not base.

I posted a link to here on my blog.

I ran some numbers of my own and I had to make some adjustments to the numbers since I don't know what Intel's reference point is. The following are the adjusted numbers I came up with.
I estimated 176/163 for Nehalem on SPECint/SPECfp rate base 2006.
I estimate 123/121 for Shanghai 2.8 SPECint/SPECfp rate base 2006. |

Thanks wolf, but I was interested specifically in something I saw on the inq, they say the 2 core, 4 core and 8 core are coming "in late" and that's it, is there a date in the slides? Specifically I want to know about the 8 core desktop/enthusiast chips.

Hiroshige Goto says:
Bloomfield/Lynnfield Nehalem-EP (Native Quad-Core) Q3 08
Dunnington (Native Hexa-Core for old FSB) Q3 08
Nehalem-EX Beckton (Native-Eight-Core-Nehalem) H2 09
http://pc.watch.impress.co.jp/docs/2007/1018/kaigai394.htm
Dunnington only for MP-Boards (4 Sockets)
Nehalem-EP is for Single- and Dual-Socket-Configurations.
There is no Beckton planned for DP-Boards or Desktop, big Server-Iron only. |

Hehe, yep. Thanks, but you were right, nothing much else of interest in there and no dates for nehalem, not sure what the inq was talking about. oh well.
