What would the difference If I used a Phenom II X2 processor
Wikipedia diz melhor:
The Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series. However, unlike its Phenom siblings, it does not contain any L3 Cache.
Além disso,
Vale a pena mencionar que existem processadores Phenom II específicos, baseados em um núcleo Athlon II, que também não tem cache L3, embora ainda seja comercializado como Phenom II.The Phenom II triples the shared L3 cache size from 2MB (in the original Phenom line) to 6MB, leading to benchmark performance gains as high as 30%.
