The amount of misinformation in this thread is staggering. Let's get a few things straight.
You CAN use GDDR memory as main system memory. The XBOX 360 has done this for years with GDDR3. GDDR tends to be quite a bit faster than standard DDR as far as effective clock speed goes. This gives you more bandwith to work with.
Both the PS4 and the One use x86-64 CPUs. x86 is the official moniker for the architecture. x64 is just the x86-64 extension that allows it to use more than 4GB of system memory. The original architecture is still x86, and the 64 bit extension is AMD64 originally, and the intel implementation (licensing from AMD) is Intel64. It's the same architecture But nobody said x64 because it's still x86.
The CPU and GPU that is being used in the One and the PS4 is still orders of magnitudes faster than current consoles. The GPU in the current 360 is based on the old ATi X1900 chip- and is about as powerful as a modern intel integrated GPU, and the PS3 is essentially a Geforce 7800. And the CPUs blow the doors off the old consoles as well.
Something you probably didn't know, did you know that the original XBOX used an Intel Celeron 733Mhz CPU? Bet you didn't. Did you know that the 360 CPU is a Tri-core 3.2Ghz chip but is in-order, so it is actually fairly weak? The cell core was a stupid idea that didn't work and was difficult to program for.
By Microsoft and Sony switching to x86, it allows all 3 systems to use the same software. they don't have to recompile for RISC, x86, AND the proprietary IBM Cell architecture. It's all just x86, which makes it easier to have consistency in performance ,and cheaper to make games.
