So will the 6 core AMD will outperform i7?

HT does NOT make it 8 threads at 4GHz ... HT uses otherwise wasted cycles to run something meaningful (say another thread) - the more optimised the OS and the program, the less help HT is.

The very nature of CPU design now a days means that large parts of the CPU are idle regardless of how efficient the software is.

Personally I think the 2 extra cores of Thuban will be on a par with the 4 HT threads of i7 at best.
 
I expect it will be overkill for me for a good while, given the most demanding thing I usually do is gaming.

If one comes up for £35 as a potential unlocker, I might have a crack at it though (which was what happened with my gambled upgrade from dual to quad).
 
Athlon X2 5000+ 45nm AM2+ 2.2GHz (the original native x2 version is 65nm, AM2 2.6GHz).

It's basically a Phenom II x4 940, with 2 cores and the l3 cache locked and an 11x multiplier.

Unlocks to Phenom FX-5000, which as far as I can tell is an easter egg AMD left for unlockers.

Still available online (new retail) for £35. OCUK don't sell them unfortunately.

The 11x multi can hurt overclocking on some boards. I've seen a screenshot of someone running one at 3.8GHz on a gigabyte board. Most people hit a motherboard or RAM wall before anything like that though. My motherboard won't POST reliably over 3.3 so although the chip could go higher I can't take it there.

Most of the first ones released unlocked. I'm not sure success rate is so good now.

Idle parts are generally to do with functions that are not being used at the time, something that HT cannot help with surely (it can if there are two separate programs being used each with different requirements, but for a game each thread is likely to be doing similar things). HT is more to do with wasted cycles by having a call from one thread, followed by a call from another thread and cycling this quickly so that the program doesn't notice but the CPU use is optimised.
