Hothardware put the new flagship 2.5GHz Phenom X4 9850 to the test and published a performance review.

Quote from the review: "AMD has finally gone into full production with a new mask spin of their Phenom processor now dubbed the Phenom X4. The new flagship 2.5GHz Phenom X4 9850 is representative of a new revision of the native quad-core Phenom silicon that resolves the well known TLB errata. Quad-core Phenom X4 processors based on the new B3 revision silicon should be hitting store shelves in the not too distant future. In addition to resolving the TLB bug, AMD is also unveiling some higher clocked Phenoms and tri-core and low-power models too."
