what were they variables in that benchmark test? All of the ones I've looked at have pointed to AMD, especially with multitasking.
Are you sure you're not mixing Core 2 Duo/Extreme and Pentium 4/D/EE. Different variations of the Pentium 4's Netburts architecture has been Intel's main processor for the last 5 years. But last month Intel released a completely new architecture which changed everyting. So any benchmarks pre-dating July 14th 2006 are obsolete. For the new situation you can look at the
this Core 2 review, aptly named The Empire Strikes Back, for example. Nowadays, from a strict performance point of view, Intel is better. Period.
A few highlights:

As you will soon see, Intel's new Core 2 lineup has basically made all previous Intel processors worthless. The performance of the new Core 2 CPUs is so much greater, with much lower power consumption, that owners of NetBurst based processors may want to dust off the old drill bits and make some neat looking keychains.

The 2.4GHz E6600 turned out to be quite an overclocker in our tests. Even though it was hard-locked at a 9 multiplier it reached an amazing 4GHz in the overclocking tests. That represents a 67% overclock.

Final Words
Intel's Core 2 Extreme X6800 didn't lose a single benchmark in our comparison; not a single one. In many cases, the $183 Core 2 Duo E6300 actually outperformed Intel's previous champ: the Pentium Extreme Edition 965. In one day, Intel has made its entire Pentium D lineup of processors obsolete. Intel's Core 2 processors offer the sort of next-generation micro-architecture performance leap that we honestly haven't seen from Intel since the introduction of the P6.
Compared to AMD's Athlon 64 X2 the situation gets a lot more competitive, but AMD still doesn't stand a chance. The Core 2 Extreme X6800, Core 2 Duo E6700 and E6600 were pretty consistently in the top 3 or 4 spots in each benchmark, with the E6600 offering better performance than AMD's FX-62 flagship in the vast majority of benchmarks. Another way of looking at it is that Intel's Core 2 Duo E6600 is effectively a $316 FX-62, which doesn't sound bad at all.
