AMD is launching B3 Phenom quad-core CPUs today. You will easily distinguish them from the TLB bug-infested B2 parts by their 9x50 designation.

The cheapest Phenom 9550 replaces the 9500, it's clocked at 2.2GHz and priced at €149, just like its predecessor. Two more models are currently listed, the 2.4GHz 9750 for €249 and the 2.5GHz 9850 for €177, but as you can see the price for the 2.5GHz model is obviously wrong.
The TDP for models up to 2.4GHz is 95W, while the 9850 is rated at 125W.

We're also expecting to see a 9850 Black Edition as well as the 9950 clocked at 2.6GHz, but these parts aren't listed yet, and we don't know the exact pricing at press time.

You can probably expect the first reviews to start popping up around the net pretty soon, so keep your eyes open.
