I'm afraid you have been SCAMMED, as Intel has been bribing the benchmark software companies to rig their tests. there is currently a major investigation in the EU over this and it looks like Intel may get even more in fines than they had to shell out to AMD over their OEM bribery scandal. The latest one caught was Cinebench, if their software detected an AMD APU/APU it would drop ALL SSE optimizations and run ALL the math in X87 mode, a mode that has been depreciated since the P3. yes they were rigging THAT badly.
If you take the rigged benchmarks out of the equation? Then surprise surprise AMD chips trade blows with chips costing more than twice as much [https://www.youtube.com/watch?v=eu8Sekdb-IE&list=TLRt7C-qG9964] with several tests the AMD outright smoking and in others within a couple percentage points of the i5s. Again we are talking about $120-$150 chips against $300+ chips and when you figure up how much more powerful your hardware could be if you put that extra $150 into the GPU or more RAM? Its really easy to choose AMD over Intel in the sub $700 mainstream price point. Oh and the AMD wrecks your power bill [https://www.youtube.com/watch?v=fBeeGHozSY0] bullshit is just that, with 17 years required to make Intel come out ahead on power savings versus the increased cost.
So DO NOT BUY THE LIES, Intel has been caught over and over AND OVER committing bribery and outright market rigging to insure they can get the press and benches to say what they want it to. The fact that they have risked so many fines and sunk so many hundreds of millions on bribes should make you ask yourself one simple question.....if they were REALLY so far ahead, why risk it? Why not simply stand on their merits and let the chips fall where they may? Maybe because they are NOT as far ahead as the rigged benches they paid for indicate and they are afraid of losing their jacked up premium if they have to compete in a fair market?
