The appearance of three core processor from AMD is completely expected. First, AMD representatives many times declared, that they are not assembled to encourage Intel in the race of growth in the processor cores number . Secondly, they recognized that four cores is too much for the majority of desktop systems. Finally, the monolithic design of phenom processors generation with four core on one crystal left place for a certain rejection, and trincore processor in this sense is the sensible resources savings .
Software developers also divide similar opinion , in interview with (Tim sweeney) from Epic games. As asserts the developer of unreal 3 engine , the latter is capable to effectively work with a number of flows, which exceeds two. This engine uses two main flows, and also scaled collections of auxiliary flows. In this sense the third flow can be occupied by physical effects. Thus, Tim concludes , this tricore computer architecture can ensure higher speed operation in physics in comparison with dual core computer.
Additional processor cores also can increase the degree of detailing. All games on base of unreal 3 engine can effectively scale the performance with growth in the number of processor cores from one to four. In the remaining cases additional cores can be used for background task when user is occupied with game.
