A common misconception that assumes "simple programs". Let's look at a hypothetical game with a few worker threads and a few "other" threads, take the worst example, 8 threads. On a dual core cpu, you immediately see the problem, every thread gets less than 1/4 of a core. On a quad-core, hyperthreading processor, each thread would roughly get (a little less than) half of a core. Suddenly your super 3.5GHz quad core processor behaves like an 8 core 1.6GHz processor. To make a long story short, whether the 8core PS4NextBox processor is weak or strong entirely depends on how the game code is organized. If it is well organized (particularly no cache stalls between the two 4core groups in the rumoured Jaguar-type processors), then an 8core processors could perform better than quad-cores. If you program a tic-tac-toe-like game on the PS4nextBox, then indeed the processors will be weak, otherwise 8 cores can (but need not be) a real bonus.
