Let’s take a look at how the AMD Phenom II X4 955 Black Edition processor does against a couple dozen other processors.
AMD clearly has budget friendly processors that have great features and clock frequencies. The AMD Phenom II product stack is starting to look really good with prices starting out at $119 and rising up to $245. At just 800MHz and less than a Volt of power running to the processor it becomes a more energy efficient platform. If you enable AMD Cool’n’Quiet the processor will automatically reduce it’s internal multiplier down to x4 and lower the core voltage for power savings. The first graph shows the relative performance of the CPU compared to the 10 other common (single) CPUs in terms of PassMark CPU Mark. This is made using thousands of PerformanceTest benchmark results and is updated daily. Based on pricing alone, the Phenom II X4 955 could be best compared to the $264 Intel Core 2 Quad Q9550 2.83GHz processor. Price and performance details for the AMD Phenom II X4 955 can be found below. The best part of the Phenom II X4 955 is that is can be purchased for just $245 shipped. With a clock frequency of 3.2GHz, the Phenom II X4 955 Black Edition is the fastest clocked quad-core processor AMD has ever released.

What is even better news is that AM3 processors are 100% backwards compatible with motherboards using AM2+ sockets, which means you do not have to run out and buy a brand new Socket AM3 motherboard and a DDR3 memory kit to upgrade to one of these processors. This new memory controller allows the processor to run both DDR2 and DDR3 memory kits, which is good news for AMD as up to a 5% performance boost can be seen when running DDR3 memory on Phenom II processors. This processor is based off the same 45nm ‘Deneb’ core that the previous Phenom II processors use, but with a few tweaks and a new memory controller. Late last month AMD announced the Phenom II 955 Black Edition processor, which is more than just a 200MHz speed bump as brings socket AM3 support to the very top of AMD’s desktop offerings. It is hard to believe it has been five months since AMD announced the Phenom II X4 940 processor, but it has been. If your motherboard has a AM3 AMD CPU socket, then check out the manufacturer's website to see they have added AM3+ CPU support for your specific motherboard model.In our review of the Phenom II X4 940 processor we saw that the new 45nm processors looked much improved from both a performance and overclocking stand point. Currently (October 2009) the locked version of Phenom II 955 is available only as an OEM processor. All other features of this processor are the same as on Phenom II X4 955 Black Edition CPU, and it's performance matches performance of non-overclocked 955 BE microprocessor.

While AM3 motherboards do not officially support the newer AM3+ CPUs (Vishera, Zambezi), some motherboard manufacturers have released BIOS update that allow their AM3 motherboards to work with AM3+ CPUs. HDX955FBK4DGI is a model 955 processor with locked clock multiplier. Motherboards with AM3+ AMD CPU socket supports both AM3+ (Vishera, Zambezi) and AM3 (Phenom II, Athlon II, Sempron) CPUs right out of the box.
