With six physical cores AMD will be able to demonstrate rather high performance in multi-tasking and applications that need to execute numerous threads at once. Moreover, as future video games that rely on DirectX 11 start to arrive, the advantages provided by six-core Istanbul processors, which AMD currently ships onto server markets, will be even more apparent, even despite of the fact that current six-core chips do not officially support DDR3 memory (it does not mean there is no controller inside, it may be disabled since there is no infrastructure for multi-socket AMD servers that supports DDR3) and have to rely on DDR2. At present AMD only ships six-core Opteron chips at 2.20GHz, 2.40GHz and 2.40GHz clock-speeds, but it should not be that hard to pick up chips that can function at 2.80GHz or 3.0GHz.
