That is a single benchmark using a single PC program. That would not be very accurate, look up several more comprehensive reviews online for a better picture. AMD's APU's, their current generation anyway, blends a Phenom II quad core CPU with a Radeon 6550 graphics core on the CPU die itself. This is different from traditional integrated graphics which had the GPU on the motherboard and, frankly, sucked. This means that a user can get a decent X86 CPU with much better graphics without the need for a discrete add-in graphics card. Because of this, APU-based systems are ideal for home theater PC's, home office PC's, or simply PC's where the need for a graphics card surpassing a Radeon 6550 would be overkill.
As for the RAM thing, Phenom II's, and even Phenom and Athlons before, use AMD64 which is an implementation of x86-64 which is an extension of x86 architecture. To use 4GB or more of RAM, you need a 64-bit capable CPU, a 64-bit capable motherboard, and a 64-bit operating system. Since AMD's APU's use the Phenom II core, which is 64-bit compatible, they are capable of running more than 4GB of RAM. In fact, all FM1 motherboards can take far more than 4GB of RAM. Core count has nothing to do with maximum memory.
AMD is going to be continuing with the APU idea. Sometime in 2012, they will put out their "Trinity" based products which will blend a Bulldozer CPU core with a Radeon 7000. The Trinity CPU's will use a different socket from the Llano's currently on the market.
