The company's two founders, Nigel toon and Simon Knowles, co founded icera, a chip company, and NVIDIA acquired icera for $435 million in 2011. "We are confident in building our future products and businesses," Nigel toon, co-founder and CEO of graphcore, said in a statement after the announcement of the financing. The technology of graphcore is groundbreaking, and its performance is better than that of chips with traditional architecture, such as GPU, because our hardware can be used with customized software, so as to improve the efficiency of AI developers. " At present, graphcore has provided tens of thousands of chips to customers including Microsoft and Dell, but the company is still in the stage of investment expansion, with a loss of more than $95.9 million and a revenue of just over $10 million in 2019. Graphcore has offices in the United Kingdom, the United States and China, with only about 450 employees and will increase to about 600 by the end of next year. Lu Tao, senior vice president and general manager of graphcore in China, once said in an exclusive interview with China first finance and economics reporter in the middle of this month: "the IPU chip products launched by graphcore hope to promote AI researchers to realize innovations that cannot be realized on GPU." He also said that in order to achieve high-performance computing, there are still challenges including system level network scalability, software level optimization and algorithm level innovation. < / P > < p > graphcore has launched two generations of IPU products. Lu Tao revealed that the third generation of IPU products are under development. Speaking of the competition with NVIDIA, Lu Tao said: "NVIDIA's GPU has built up a very large ecosystem through years of development. It is the only challenge in the current market in our opinion, and we need to pay close attention to its progress." < / P > < p > < / P > < p > < / P > < p > use wechat scan QR code < / P > < p > to share with friends and circle of friends < / P > < p >
