FUD Zilla claims usage of DDR3 memory on AMD Phenom II systems will result in an overall performance boost of around 5 percent. The first Phenom II Socket AM3 processors with DDR3 support are expected in February 2009.
This is not really miraculous, but all who go for a DDR3 platform might actually have a slight gain in performance. The price advantage still stays with ultra cheap DDR2 memory and if you are not latest greatest you would rather stick with DDR2 as it will be fast enough.
The upcoming AM3 chipset won’t overclock much better, it will offer the same overclocking performance as the same chipset for DDR2 and if you remember, AMD’s memory controller is inside of CPU. The Phenom II, Deneb core in AM3 has both DDR2 and DDR3 memory controller and if you plug it in AM3 you are stuck with DDR3, while the same CPU in AM2+ will be DDR2 only. This only works with Phenom II AM3 CPUs, while the first two to launch as AM2+ are limited to DDR2 only.
