On the Big List of Mobile Processors benchmark
Phenom II X2 N660 is ranked #81 and
AMD A4-3310MX is ranked #198
, AMD A4-3300M is ranked #208.
I think that HP Pavilion g4-1117dx has the default A4-3300M and not the slightly more powerful A4-3310MX which is an option.
BestBuy site doesn't specify what APU it actually has.
Yes they do, just not in the spec section.
While the N660 vs A4-3300M is pretty large it's not a total stomping in processor power.
It's just that they're both kinda weak, dropping down so low.
