Ask any woman or gun enthusiast and they'll tell you the same thing: size matters. In the great PS4 vs Xbox 720 debate the size that matters is the teraflops. For those not in the technical know, teraflops are essentially a unit of measurement for overall computational power. So, if you add up what the CPU, GPU, RAM, etc. in a system can handle you get your teraflops. And, according to leaks, PS4 is about 50 percent bigger than Xbox 720 in the teraflop department. Sources told VG247 that the PS4 will have a run capability of 1.84 teraflops. The Xbox 720 will have only 1.23 teraflops. Does this mean the PS4 will be 50 percent superior to Xbox 720? Both systems will likely feature 8 GB of RAM, but the power of a system isn't necessarily related to the guts of the system. A big portion depends on how developers take advantage of the hardware, and we still don't know enough about the background programs in the OS for each system to know how much RAM will be available for gaming.
