This is roughly equivalent to fast-forwarding technology about seven years into the future (three generations of Moore’s Law),” the blog said. “TPU is tailored to machine learning applications, allowing the chip to be more tolerant of reduced computational precision, which means it requires fewer transistors per operation. Because of this, we can squeeze more operations per second into the silicon, use more sophisticated and powerful machine learning models, and apply these models more quickly, so users get more intelligent results more rapidly.”The tiny TPU can fit into a hard drive slot within the data center rack and has already been powering RankBrain and Street View, the blog said.<a href="http://www.pcworld.com/article/3072256/google-io/googles-tensor-processing-unit-said-to-advance-moores-law-seven-years-into-the-future.html?token=%23tk.PCW_nlt_pcw_tech_html_2016-05-19&idg_eid=86e53fe6080bf8ccdf14d51f6baa1739&utm_source=Sailthru&utm_medium=email&utm_campaign=Top%20Stories%20%40PCWorld%202016-05-19&utm_term=pcw_tech_html" target="_blank">http://www.pcworld.com/article/3072256/google-io/googles-tensor-processing-unit-said-to-advance-moores-law-seven-years-into-the-future.html?token=#tk.PCW_nlt_pcw_tech_html_2016-05-19&idg_eid=86e53fe6080bf8ccdf14d51f6baa1739&utm_source=Sailthru&utm_medium=email&utm_campaign=Top Stories @PCWorld 2016-05-19&utm_term=pcw_tech_html</a></blockquote>
