Is 6 cores better than 4??
The answer as usual is : It depends.
If the effectiveness of the individual cores were equal, and the price were the same, it would be no contest.
6 is better than 4.
Such things are not equal.
Intel cores are faster than FX cores across the board, and by a considerable margin. Perhaps 50% better.
Then, one needs to consider the use the cpu will be put to.
For a multi threaded app where all cores can be fully utilized, the FX chips can hold their own, and even beat intel for lower priced builds.
Not in the case of the FX-6300 vs, 4690K though.
For gaming, it also depends.
Few games can effectively use more than 2-3 cores. Probably the best case for a many core cpu would be multiplayer games with many...
