I see it being more of a hack (instead of a feature) to help fix the problem of pipe stalls. The next new Intel models will _not_ have this 'feature'.
How so? Its clearly an SMT feature. One that improves the operational performance of the chip by what up to 30%? And by only using 5% more space on the die... come on whats next, are you going to tell me that L2 cache is nothing but a hack to reduce memory access time? Pretty much every feature of an engineering undertaking is a "hack" if you want to analyse it like that. Thats what engineers do, they see a limitation in a design or process, and come up with a novell way of eliminating/reducing it.

Yonah is not a brand new architecture. Its a twiced recycled design from the P3 and Pentium-M.
The Conroe is a spanking new design and is much faster than the dual core AMDs.
Granted, I should have said core... So, again, why isnt the T2600 beign compared to the AM2? That will put another few % on AMD's score.

The reviewer was correct to overclock the Yonah. The objective was to compare different cpu's of approximately the same _cost_ not clock speed. Since the FX60 is about $400 more expensive then the T2600, the overclocking is justified.
Well, actually thats wrong. Thats not the reason he did it... From the article...
"First, we benchmarked at its default 2.16GHz clock speed to find out how fast the chip was at its factory settings, and then also tested at 2.6GHz in order to compare the Yonah architecture in a clock-for-clock shootout with AMD's Athlon 64 FX-60."

There is a point to be made about price, but this was more of a technological/performance test. Lots of other cheaper processors out there perform very well when OCed. I personally would not buy an FX-60, or any top notch processor at that sort of price.
