After reading a couple of interesting tests of new AMD motherboards that are set to use the AM3 processors, along with DDR3 memory, it has become clear that DDR3 in an of itself isn’t really that much faster on the systems, when compared with similar systems using DDR2. In most of the tests the differences are well within the margins of error. (see here)
While some Intel fanboys would say that it takes the power of the i7 series to make a difference, I have seen good evidence that it has nothing more to do with CPU power, and all to do with actual bandwidth. This would indicate that AMD might want to make changing the width of the memory bus a priority in the next design round, as it seems they are still gun-shy about ramping up processor speeds across the board.
No one seems to be speaking much about the i5 processors that are soon to appear, and when they do, it should cause a fire to be lit under the AMD camp’s collective butts. While Phenom II is a great processor, it is more than time to shoot for the top, on at least one processor, so that the AMD faithful have some bragging rights about the top end.
Initially, I was under the impression that the Istanbul six-core might do the trick, but most people who are worried about power right now are game players, not video encoders, so a triple core AMD running at about 4.5 GHz should do the trick. (see here) Of course, it would help to have a 4 way path to some DDR3 memory.
