Phenom

Phenom (pronounced as IPA:/fenɒm/, as in the word phenomenon) is the AMD desktop processor line based on the K10 (not "K10h") microarchitecture [1], or Family 10h Processors, as AMD calls them. Triple-core versions (codenamed "Toliman") will be the Phenom 8000 series, quad cores (codenamed "Agena") in the Phenom 9000 series, and high-end enthusiast versions (codenamed "Agena FX") in the Phenom FX series. AMD considers the quad core Phenoms to be the first "true" quad core design, as these processors are a monolithic multi-core design (all cores on the same piece of silicon wafer), unlike Intel's Core 2 Quad series which are a multi-chip module (MCM) design. The processors will be on the Socket AM2+ platform [2], with the exception of the high-end model which will only be available for Socket F+. The dual core K10 processors will still be named Athlon X2.
