Throwing more transistors onto a single piece of silicon may sound like a magic bullet, but it really isn’t adding more transistors to the chip will only improve performance if all of these transistors get used. More Transistors Doesn't Always Mean Higher Efficiency It builds chips with a large amount of redundancy, repeatedly building 84 identical tiles to create an array of silicon blocks. Image used courtesy of Cerebras SystemsĪccording to Cerebras, the WSEs are created by removing the largest possible square from a 300 mm wafer, which results in a 46,000 mm 2 chip. Size of the WSE-2 compared to the largest GPU. Cerebras unique manufacturing process is the key to its high integration and seemingly fast time to market-considering the fact that the company added 1.4 trillion transistors to its chip in two years. The increased performance and integration of the WSE-2 is a result of the wafer's move from a 16nm node in Gen1 to TSMC’s 7nm node for Gen2. Image used courtesy of Cerebras Systems and HPC Wireįurthermore, Cerebras claims the new chip bypasses GPU competitors with: Based on these metrics, the Gen2 WSE doubles the performance of the first-generation chip on all shown metrics. These transistors serve to deliver a huge amount of functionality with the Gen2 offering 40 GB of SRAM, 20 PB/s of memory bandwidth, and 220 Pb/s of fabric bandwidth. As a reference, the world’s largest GPU has about 54 billion transistors, making the Gen2 WSE over 2.5 trillion transistors larger. In an area of 46,225 mm 2, the Gen2 WSE integrates 2.6 trillion transistors and 850,000 AI-optimized cores. Like the first generation WSE, Cerebras’ second-generation WSE is a massive piece of silicon aimed at AI compute applications. Now, the company is pushing the limits of this wafer even more with the release of its second-generation WSE-this time more than doubling the transistor count in the same area. The startup's first WSE came in at about 8 inches by 9 inches and integrated roughly 1.2 trillion transistors into one chip. On the other end of this conversation is Cerebras Systems, a company that invented the so-called "world's largest computer chip," the Wafer Scale Engine (WSE), back in 2019.Ĭerebras’ second-generation WSE compared to a hockey puck. By the end of the 1950s, silicon had become the industry's preferred semiconductor material.Most of the conversation today around chip design focuses on how we can make chips smaller to pack more punch into one area. ![]() With little competition, TI dominated the silicon-transistor market for the next few years and made significant inroads into Raytheon's position as the largest merchant market supplier of transistors. Unaware of Tanenbaum's work, Teal presented this achievement on May 10 at an Institute of Radio Engineers conference in Dayton, Ohio, creating a sensation by announcing that silicon transistors were in production and available for sale. Employing high-purity Dupont silicon, they made their first successful silicon transistor - an n-p-n structure using the grown-junction technique - on April 14, 1954. Having left Bell Labs to organize a research lab at TI, Teal hired a team of scientists and engineers led by chemist Willis Adcock to work on silicon transistors. In January 1954 Bell Labs chemist Morris Tanenbaum fashioned the first silicon transistor using a variation on Morgan Sparks and Gordon Teal's grown-junction technique.īut the Labs did not pursue the process further, thinking it unattractive for commercial production, which allowed Texas Instruments (TI) to claim credit for this breakthrough several months later. ![]() Silicon devices that function from -55 to 125☌ became possible after Dupont began supplying high-purity "semiconductor-grade" material. ![]() They are also restricted to 0 to 70☌ operation, which limits their use in rugged applications. Although this element is much easier to work with than silicon and allows higher-frequency operation, solid-state devices made with it have far worse leakage currents in the "off" condition - an anathema for computer logic. For the first six years of their existence, transistors had all been made with germanium.
