THG gets their hands on a engineering sample AM2 X2 4800+ and compares it’s performance to the current S939 4800+.

As our benchmarks show, going from DDR400 to DDR2667 with current silicon would not make a noticeable difference at all, because the integrated memory controller suffers more from relaxed memory timings than it can gain from speeding up clock speed via DDR2. Whether the current engineering sample processors actually suffer from a memory controller bug is hard to say. This could also be due to information that was released intentionally to prevent people from doing early benchmarking.
I didn’t expect DDR2 (533, 667) to add any performance. The jury is out on DDR2 800 though
