Epic Games’ CEO Tim Sweeney recently commented that the tech demo called Samaritan required 2.5 terraflops of processing power to run. To contrast, that’s ten times more power than the Xbox 360 has, which is capable of .25 teraflops.

While the demo was running on an advanced version of Unreal Engine 3, it is believed to be demonstrative of what the Unreal Engine 4 will be able to produce. Epic will show off the Unreal Engine 4 in 2012 and fully launch the tech in 2014.
