REX Computing is a fabless semiconductor company founded in 2013 that develops a new processor architecture called Neo, designed to dramatically improve power efficiency and programmability for high performance computing. The Neo chip features 256 cores, scratchpad memory, a 2D mesh interconnect, and a high bandwidth chip-to-chip interconnect, delivering 10 to 25 times greater energy efficiency compared to current GPU and CPU systems. Targeting supercomputers and embedded applications, the Neo processor achieves 256 GFLOPs double precision performance at 64 to 128 GFLOPs per watt, enabling capabilities traditionally limited to large data centers in low power environments. REX Computing combines hardware simplification with a modern software toolchain to optimize memory management and programmability, aiming to overcome the energy bottleneck caused by data movement in traditional processors. The company is led by founders Thomas Sohmers and Paul Sebexen and has received seed funding from Founders Fund.
