You are joking, right? Do you know that intel has a 6 core 3.33 GHz CPU? And that each of these cores can do twice as much as an A9 core does per cycle, making the i7 about 20 times as fast as a dual core Cortex-A9. This is the usual ratio between top of the line x86 and ARM for the last 15 years. Dual core 1GHz SoCs are nothing new, actually. MIPS had those in 2002, so ARM still has a long way to go even to catch up with MIPS architecture, let alone X86.
