Because of yield issues with the eRAM chip, they're contemplating on downgrading the specs by lowering the clock speeds in different components. So much in fact, they're going from a 1.2 Teraflop system to 800-900 Gigaflops. For reference the Xbox 360/PS3 are about 200 Gigaflops each with PS3 at 220-250 and the Wii U at around 300-400 Gigaflops. PS4 is 1.8 Teraflops or 1800 Gigaflops.
