People tend to forget that the enthusiast community is not where AMD makes their money.
Example: 1055T (95W version) is probably the best power per watt CPU of the Phenom II series, since it runs 6 cores @2.8GHz + 6MB L3 cache (I think). Anything lower end is way less efficient per core/watt, like any Athlon/Sempron excluding their e-series versions, so my point still stands. No mainstream PC manufacturer like Dell will use it when they can use a cheaper Intel counterpart that will save them on PSU costs by using way less power at both idle & load and extend the lifespan of their PCs, thus saving them possible returns/warranty costs.
EDIT: server and the mainstream markets are where AMD makes their money. Their 16 core BD will flop big-time against their current Phenom II based 12 core Opteron, if current Bulldozer efficiency/performance is anything to go by and same goes for everything mainstream.
