AMD releases new Phenom II X4 945 and 955 BE

AMD will now refresh the lineup with two new processors: the Phenom II X4 955 Black Edition and Phenom II X4 945. Both processors are modestly priced, with the Phenom II X4 955 Black Edition at $245, and the Phenom II X4 945 at $225.

The 955 Black Edition and the 945 are clocked at 3.2GHz and 3.0GHz, respectively. Black Edition processors have unlocked multipliers to make overclocking easier for PC enthusiasts. The processors differ only in clock speed, and have identical specifications otherwise. The Phenom II X4 processors will come with 64K of L1 instruction and 64K of L1 data cache per core (512KB total L1 per processor), 512KB of L2 data cache per core (2MB total L2 per processor), and will also have a shared 6MB L3 cache.

The two new processors are based on AMD's AM3 socket but will also work in most AM2+ motherboards. Because they support both sockets, the processors also support both DDR2 and DDR3 memory, respectively found in AM2+ and AM3 socket based motherboards. Using DDR2 the processors will have 17.1GB/s of memory bandwidth, and using DDR3 the bandwidth jumps up to 21.1GB/s. Older Phenom II X4 processors, like the 940 Black Edition and the 920, use AMD's AM2+ socket.

The Web site notes that hobbyists with early access to the X4 955 BE chip have been able to clock it at up to 6.7 GHz.
