Agreed.
Also, it's more comparable to look at something like an i5-4440 vs the FX-8350 for roughly the same price.
I bought my i7-3770K because it can convert video about 30% faster than the i5-3570K, but gaming performance is mostly identical.
As for AMD processors, just look at the Benchmarks for different games. Some newer ones compare to a similarly priced i5, but SKYRIM for example is 40% faster on the i5-3570K versus the FX-8350.

The short version: an Intel core is more powerful than an AMD core. That's why a quad core Intel CPU can outperform a 6-8 core AMD CPU. If you really want the nitty gritty, you can research the architecture and whatnot for the exact whys. The only real reason you would want an i7 over an 8350 is a) if you're doing a lot of video editing or 3d modeling or something to that effect and b) you have the money.
An i7 makes use of hyperthreading. Each processor CPU has two instruction sets feeding it, a main task, and a secondary task. If the primary task completes early in the cycle then the processor sends the seccond task through, allowing you to complete two cores worth of work for one core. It does not scale necessarily perfect.
I have an i7 4770k and I found that hyperthreading adds about 50-60% for cpu power benchmarks.
The reason games don't use hyperthreading is because they need take done immediately, and not a clock cycle later when an opening appears.
As for AMD thier processors are the other way around, they share all the resources (commie processors from team red), and when the processor turns on for a clock cycle some cores might be hogging the cache, or instruction sets are to busy feeding one core to help the others (AMD fx series have two cores per instruction set) and they will frequently skip a clock cycle, or sit idle.
These reasons are why a 4 core intel can blow away an 8core AMD for preformance.
But all the preformance comes with a price.
Hope this helps you
