The American company Cerebras has created the world's largest chip, the third-generation Wafer Scale Engine (WSE-3), which is the size of a dinner plate and designed to train artificial intelligence at record speed. Unlike Nvidia, Intel, and AMD, which cut a silicon wafer into hundreds of small chips, Cerebras keeps the entire wafer as a single colossal processor. According to IEEE Spectrum, the WSE-3 is square with 21.5 centimeters on each side and uses almost an entire 300-millimeter silicon wafer, resulting in around 46,000 square millimeters of area. Traditional manufacturers typically limit chips to at most about 800 square millimeters. According to Interesting Engineering, the chip contains 4 trillion transistors and 900 thousand cores optimized for processing artificial intelligence, manufactured by TSMC using 5-nanometer technology. According to IEEE Spectrum, the processor also embeds 44 gigabytes of memory within the chip itself, which avoids slow data back-and-forth and provides extra speed.
