why are the amd rings using a 500W PSU and the intel a 700W, especial when max consumpton is only 13W appart?

even the inq noticed this...
This is where analyzing power efficiency numbers can be tough. AMD is going to do what any company will do to promote a product. They configured their system, then configured the Intel system in a similar matter.

Intel's Achilles heal is FBDIMMs, any power efficiency in the CPU is lost in the memory. If you scan through all the other benchmarks, there are intel systems scoring 1000+ but do not utilized 16 Gigs of 8 sticks of 2 Gigs apiece. So take the AMD submission with a grain of salt.

But Informal made the right observation -- the full load ssj_ops for Shanghai vs equivalently clocked Harpertown is higher, even in cases of 2 instant JVMs ... unfortunately, since there is no Barcelona SpecPower benchmark submitted, it is not possible to validate 20% claims ... but the raw performance showing against Harpertown is impressive. i.e. http://www.spec.org/power_ssj2008/re...519-00056.html
It would appear a 2.7 GHz Shanghai in two sockets is about the same as a 3.0 GHz Harpertown.
