Ohhh my.
Just look at those results. The overclocked AM2 takes the top spots, closely followed by the overclocked FX-60, stock AM2 5000+ and stock FX-60. The overclocked D 930 is in fifth place.
It's worth mentioning that the overclocked AM2 results are for a processor running at 3GHz, which would be roughly equivalent to a future AM2 FX-64.
In other news, the equivalent stock X2 3800+'s are giving basically identical results, and the stock FX-60 and stock 5000+ are once again almost identical. There is definitely a pattern developing here.

Frankly I was surprised to see the AM2 - even when significantly overclocked - dominate here. The DDR2 controllers in the 975 chipset are based on mature technology, and even though the D 930 is front side bus limited, it works extremely well with DDR2 memory.
Here, the overclocked AM2 beats the overclocked D 930 by a healthy 9.4% - not too shabby when you consider that the AM2 was running at 3GHz with DDR2-876 memory, and the D 930 at 4.2GHz with DDR2-933 memory!
The bottom line? AMD did a very impressive job of making a low latency DDR2 controller.
This is one of the few tests where AM2 has a clear lead over equivalent socket 939 parts. DDR2 definitely shows an advantage here.
