Boy oh boy, this new processor just can't cut it. A brand spanking new processor, can't even go toe-to-toe with an aged Conroe. HotHardware has this to say:
Ultimately, the Athlon 64 X2 6000+ isn't fast enough to wrestle the performance crown from Intel's high-end Core 2 Duo processors, but it does push AMD's performance up a rung on the ladder. At this point it's clear that it's going to take much higher frequencies, or rather a new architecture for AMD to overtake Intel again. But for now, another round of price cuts will put AMD on somewhat equal footing in terms of overall value.
XbitLabs also posted their review and they aren't impressed as well:
Frankly speaking the launch of the new AMD Athlon 64 X2 6000+ processor is not a very big event. Until promising new cores based on K8L micro-architecture come out, AMD will hardly be able to surprise us with anything. After the launch of Intel Core 2 Duo processor family, AMD K8 micro-architecture turned pretty obsolete. While in the budget and mainstream market AMD manages to success just fine thanks to smart and aggressive pricing policy, then the high-performance segment seems to be a tough nut to crack for AMD at this time.
So if you want to suck, or a masochist wanting to have a crappy system, or just plainly insane, you can go ahead and own such system. On the other hand, you can still stick with your Conroe!
