The fastest computer in the world is called Titan and is made with components from NVidia and AMD. This computer can achieve 17.59 petaflops, more than 1.27 petaflops now silver medal, the IBM Sequoia.
The Titan also now "born" and already is considered the fastest computer in the world. The Titan was built by Oak Ridge National Laboratories purposely for the Department of Energy.
Titan replaces the XT5 Jaguar (which was considered the fastest computer in 2009 and 2010). In 2011, the fastest computer in the world was that the IBM Sequoia could a whopping 16.32 petaflops. But the Titan yet still managed to overcome and well. This new supercomputer is a hybrid system of NVidia GPUs and CPUs AMD.
It is a system whose architecture is known for Cray XK7 18,688 and has brains, each of them has an AMD Opteron 6247 (it is the version of 16 cores!) And Nvidia Tesla GPU K20X. How should calculate this "bug" also needs memory: 710 terabytes!
As for consumption, can not be said to be spared, but it is the computer that has the best value calculations per watt. The Titan can make a thousand quadrillion calculations per second with a consumption of 20 megawatts.
AMD is in first place (for now) but Intel processors still dominate about 76% of super-machines listed in the Top 500 worldwide.
