The Titan's Overthrown. Tianhe-2 Supercomputer New #1
The National Supercomputer Center in Guangzho, China, will host the the world's fastest supercomputer by the end of the year. The Tianhe-2, English: "Milky Way-2", is capable of nearly double the floating-point performance of Titan albeit with slightly less performance per watt. The Tianhe-2 was developed by China's National University of Defense Technology.

Comparing new fastest computer with the former, China's Milky Way-2 is able to achieve 33.8627 PetaFLOPs of calculations from 17.808 MW of electricity. The Titan, on the other hand, is able to crunch 17.590 PetaFLOPs with a draw of just 8.209 MW. As such, the new Milky Way-2 uses 12.7% more power per FLOP than Titan.
Titan is famously based on the Kepler GPU architecture from NVIDIA, coupled with several 16-core AMD Opteron server processors clocked at 2.2 GHz. This concept of using accelerated hardware carried over into the design of Tianhe-2, which is based around Intel's Xeon Phi coprocessor. If you include the simplified co-processor cores of the Xeon Phi, the new champion is the sum of 3.12 million x86 cores and 1024 terabytes of memory.
... but will it run Crysis?
... if someone gets around to emulating DirectX in software, it very well could.
