Thanks that makes a bit more sense although still poorly stated. It did say "energy instructions" when I read it.
FWIW a 30% integer performance shortfall affects far more server buyers than a 30% FP performance shortfall (especially since the latter likely refers only to bandwidth limited HPC benchmarks/apps).
I cut and pasted directly from the original article.
"If you look at performance instructions, Barcelona is about 30 percent faster than Clovertown. However, if you look at energy instructions, Clovertown is about 30 percent faster than Barcelona," Dell said.
I'm glad they clarified it because it made no sense.
