well its an amd processor with 2 seperate cores each core is 2.6 Ght
In May of 2005, AMD introduced its first "Multi-Core" Opteron CPU's. At the present time, the term "Multi-Core" at AMD in practice means "dual-core
"; each physical Opteron chip actually contains two separate processor cores. This effectively doubles the compute-power available to each motherboard processor socket. One socket can now deliver the performance of two processors, two sockets can deliver the performance of four processors, and so on. Since motherboard costs go up dramatically as the number of CPU sockets increases, multicore CPU's now allow much higher performing systems to be built with more affordable motherboards.
AMD's model number scheme has changed somewhat in light of its new multicore lineup. At the time of its introduction, AMD's fastest multicore Opteron was the model 875, with two cores running at 2.2 GHz
each. AMD's fastest single-core Opteron at this time was the model 252, with one core running at 2.6 GHz. For multithreaded
applications, the model 875 would be much faster than the model 252, but for single threaded
applications the model 252 would perform faster.
