AMD Phenom X4 9850 Black Edition review
 

In terms of performance, AMD has stated that the new B3 processors will be no faster than the original Phenom X4 CPUs without the TLB erratum fix enabled on a clock-for-clock basis. Therefore the Phenom X4 9600 and the new Phenom X4 9650, for example, should be no different in terms of performance. Just as well that should mean that today’s flagship Phenom, the X4 9850, should sit somewhere between the Phenom 9700 and 9900 processors that we reviewed earlier this year.
