CONFIRMED: Google bakes custom data centre chips

Not CPUs, but a custom ASIC for machine learning applications Google’s Tensor Processing Unit. Source: Google Google’s long-rumoured efforts to build its own silicon have come to fruition. The Alphabet subsidiary today revealed it has baked a custom ASIC it calls a “Tensor Processing Unit” (TPU) and has been using them for a year for the machine learning applications that fuel many of its services. “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,” writes Norm Jouppi, a distinguished hardware engineer at Google. “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…
