So, the early QX9770 desktop Yorkfield Extreme part was trying hard to come close to 6GHz here yesterday under deep freeze. And now we know the equivalent unlocked top-bin "enthusiast" Xeon for Skulltrail and similar boards (there is expected to be more than one board supporting unlocked dual-socket Xeons this year, not just Skulltrail) will be called QX9775. This is basically a "no holds barred" version of the X5482 3.2GHz FSB1600 part.

These - obviously - are fast parts and, with a few more steppings coming along over the next six months, Intel got that frequency headroom to something like 4GHz under normal operating conditions, something confirmed to us this morning by a very large Taiwan OEM.

So, how much will the Nehalem be faster than the already oh-so-fast Penryn, focusing specifically on the core IPC single thread performance? I asked Kirk Skaugen, Intel's Digital Enterprise Group VP and GM of Server Platforms Group[...]
