I don't think anyone had the desktop performance in the mind. I was hoping sp3 i7 could match ivy bridge i7-3630qm in my thinkpad w530, now I know I won't, if it got 80% performance I'll be happy, and I hope sp4 i7 could finally run side by side with the old thinkpad.Broadwell-m, you mean.
I"m not sure why people keep thinking theyr'e going to get desktop broadwell when mobile broadwell-m is being designed for applications like this. They also seem to think that they're going to get a 30% performance improvement because the DESKTOP components stack that way.
If I'm wrong, that's awesome. When I'm right, y'all are gonna be disappointed at the 20% performance hit the SP4 takes.
