Back in early February a source familiar with the plans of AMD revealed that AMD Phenom processor models 9550 (2.20GHz), 9650 (2.30GHz) and 9750 (2.40GHz) based on the new stepping will be released commercially in April. Various media reports now suggest that along with the launch of the new microprocessors AMD will also release model 9850 at 2.50GHz clock-speed.

If you search a little then you'll notice that the upcoming Phenom 9750 and 9850 listed at an American e-tail stores.

AMD Phenom 9850 will come as a black overclockable edition works at 2.5G GHz, has the TDP of 125W and it fits in socket AM2+. It should start selling soon and it will cost $302.99. The second fastest in this line up is Phenom 9750 with the same TDP and 2.4GHz clock. It is not a Black Edition and it will sell for $278.99. 

Both CPUs come with free shipping. You can order 9850 here and 9750 here.

The new microprocessors are based on the new B3 core stepping and should generally have a little higher performance due to the lack of the well-known TLB erratum compared to AMD Phenom models 9500 and 9600 available now.
