The Phenom seems to upgrade capabilities to offer good much beyond that go well, which AMD has not officially announced so far: It is certain that in the first quarter of 2009 planned Phenom the new Processor Socket AM3 in AM2 + motherboards work and with some AM2 boards tolerate even. For example, published Asus one of compatible to AM2 (+)-motherboards that after a Bios update not only the Phenom X4 and 940 + processor socket, but also the upcoming AM3 variant of the Phenom support is AM2 920th.

Similarly large is AM2/AM3- compatible of MSI. Numerous motherboard manufacturer Gigabyte come with the Phenom (AM2 + / AM3) clear, assuming that the BIOS version is installed. Further compatibility lists on the Internet from Asrock, Biostar, DFI, ECS, Foxconn found. The model can upgrade potential of the Phenom is driving a hand in its variable memory controller supports both DDR2 and DDR3 memory. In addition, the CPU socket AM2, AM2 + and AM3 are mechanically compatible. But it gets even better: AM3 CPUs will work in AM2 (+) sockets only if the three processor socket are electrically compatible. Conversely it should, therefore, the AM2 + version of the Athlon in an AM3 motherboard can use. From AMD we got to date the information that this was not possible.

The AMD processor-David was in terms of computing power and energy efficiency since the launch of the Core 2 processor family, not with chip giant Intel compete. With the Phenom X4, codename Deneb, AMD plans to again make up ground lost: this is AMD's Intel in manufacturing technology to open and produced the second-generation Phenom now also in the 45-nanometer process. Smaller transistor feature sizes reduce the power consumption of a processor, allow higher clock speeds and create space on the silicon chips for other circuits. AMD uses the space wisely for improvement in all areas.
