...IDC said 33,600 IPF servers worth $1.4B were sold in 2004.
That's selective reading. The same article said that Gartner estimate is 26K units per year, which would be about 6.5K servers per quarter. Even the more generous IDC estimate 8.4K servers per quarter does not seem to add up to 75K CPUs per quarter.
I would like some proof of this IDC server unit claim other than some random comment from a Sun engineer touting his Opteron boxes.
I agree with you that he should back up his claims, but Andy B. (Sun Employee #1, started 2 companies and helped finance Google) is a little more than a "Sun engineer", I believe he is their Chief Technical Officer and a billionare from his investments.
