We're going to start off with SiSoftware's Sandra here, if only because the memory bandwidth numbers are perhaps the most interesting in a platform introduction like this one. All of our AM2+ configurations employ the same DDR2-1066 modules, yet there was still a fair amount of variability between the slowest Phenom X3 8750 and the fastest Phenom II X4 940. As expected, the Core i7's triple-channel memory controller cranks out serious throughput, though our engineering sample was locked to DDR3-1066 speeds. Retail chips don't have this limitation in place and can run a more diverse array of divisors.
AMD did give us a heads-up that the current crop of AM3 motherboards was not optimized yet. But you wouldn't know it by looking at the throughput numbers, which show our AM3 platform pushing in excess of 13 GB/s. For the record, DDR3-1333 is the fastest memory setting AMD's integrated controller officially supports. However, Asus does make DDR3-1600 settings available in the BIOS of its M4A79T Deluxe.
If there were a most-important test in 3DMark Vantage for measuring processor performance, it'd likely be the CPU measurement. Here, it heavily favors Intel's Core i7 920 at 2.66 GHz, followed by the fastest Phenom II, the X4 940. In both of the other metrics, however, the Core i7 gets trounced by the rest of the field.
PCMark Vantage is loaded with the sorts of scenarios Intel's Core i7 is known to favor, so it's hardly a surprise to see the entry-level 920 taking a first place finish. The Phenom II X4 comes up a close second, though. The Socket AM3-based X4 810 outshines our simulated X4 910, despite its 2 MB L3 cache deficiencya good sign for DDR3 memory support on the newer platform.
