This morning I read that for some airlines the price of one of their shares is less than the price of a beer at the airport.
And that reminded me of some pricing claims in Sun's latest press release on their new UltraSPARC T2 servers.
Besides comparing benchmark results based on different numbers of cores and vastly different amounts of memory, comparing new Sun systems with other's old systems, and comparing actual power consumption with nameplate power consumption - big benchmark no-no's - Sun uses pricing in a footnote on a SPEC benchmark. A benchmark where pricing is not a metric. Surely meant to distract us from the fact that for these results the IBM POWER6 core offers 43% more performance than the UltraSPARC T2 core.(1)
If you're at the airport reading this blog and waiting for an MD-80, it's probably time for that beer.
