Intel is better clock for clock. And HyperThreading is a very real benefit in applications that are designed for multiple threads. In most benchmarks of multi-threaded applications, Intel chips completely dominate. Even when there is no hyperthreading and it's a 4-core intel chip vs. an 8-core AMD chip. When looking at Cinebench, for example, where the FX-8350 (surprisingly?) scores higher than the i7 3570k by 15%, the i7 3770k steps up. Admittedly, the 3770k is also clocked 2.6% higher than the 3570k, but HyperThreading actually gives it a 30.7% boost in performance. This positions it 14% ahead of the FX-8350.
You can see the same thing happen in Handbrake H264 encoding. The FX-8350 with 8 Cores @ 4.2GHz (33.6GHz total power) is about 8.5% faster than the 3570k with 4 Cores @ 3.8GHz (15.2GHz total power). However, when we enable HyperThreading and up the clocks by 2.6% ala 3770k....we get an 18.4% faster encode time over the 3570k, which means the 3770k ends up being 9.2% faster than the FX-3850.
So essentially...whatever percent increase the 8-Core AMD chip gets from multi-threaded applications over the 4-Core Intel chip, HyperThreading doubles it. I'm positive there are cases where this isn't true. But in most cases, the 3570k is faster than the AMD chip without needing HyperThreading. I understand what HyperThreading is. I know it's not free magical cores. I know it can actually slow down performance in apps not designed for multi-threading and that's why for some games and applications I disable it on my 3770k.
The argument for AMD is, and will be for the next little while, that you get more Bang for your Buck. As new consoles come out and ports start using multiple threads, the value of the AMD chips will go up even higher. And an FX-8350 at $200 will be a better buy than the $220 3570k. That's great news for AMD, and I've been waiting anxiously for the new consoles to come out so all of us can benefit from this. However, as I mentioned, this gain will be even more pronounced for current HyperThreading enabled Intel CPU's. Essentially, everybody wins. Except the 3570k crowd.
