The chip shortage has highlighted the role of substrates that connect chips to circuit boards and the companies that make them. Substrate manufacturing offers low profit margins, so investment in this sector has also been low. Now, the lack of substrates has added to the problems of churning out enough chips to serve the global market. Substrates — panels of resin embedded with wiring onto which chips are affixed — connects the die at the heart of a chip to the motherboard, delivering power and data.

On Wednesday, scammers launched one of the most audacious attacks in recent memory, posting messages from the Twitter accounts of Joe Biden, Barack Obama, Kanye West, Bill Gates and Elon Musk that if people sent Bitcoin, the famous person would send back double the money. The first attack targeted high-profile cryptocurrency leaders and companies, but soon broadened to include a list of prominent U.S. politicians and entertainment and tech executives. It appears that an internal Twitter account was involved in the attacks, but it has yet to be determined whether an employee was willfully complicit.

Los Altos, CA-based startup Cerebras, dedicated to advancing deep learning, has created a computer chip almost nine inches (22 centimeters) on each side — huge by the standards of today’s chips, which are typically the size of postage stamps or smaller. The company plans to offer this chip to tech companies to help them improve artificial intelligence at a faster clip. The Cerebras Wafer-Scale Engine (WSE), which took three years to develop, has impressive stats: 1.2 trillion transistors, 46,225 square millimeters, 18 gigabytes of on-chip memory and 400,000 processing cores.

At its Next Horizon Gaming event during E3 in Los Angeles, AMD announced an impressive family of Ryzen 3000 processors to debut July 7. The Ryzen 9 3950X, which is 16-core, 32-thread and fits into an AM4 motherboard, is priced at $750. The Ryzen 3950 X also offers a 3.5GHz base clock, 4.7GHz boost clock, 72MB of cache and 105W TDP (in comparison, Intel’s 16-core has a 165W TDP which requires a more expensive motherboard). The rest of the 7nm processor lineup, in general, is expected to offer more power efficiency at a lower cost.

Facebook unveiled new hardware for use in its data centers, designs for which will be made available to outside companies through its Open Compute Project. The announcements were made during this week’s OCP U.S. Summit in Santa Clara. One announcement centered on a new GPU server designed to better serve the company’s AI initiatives. Big Basin — successor to the company’s Big Sur high-performance compute platform — will help Facebook train machine learning models that are 30 percent larger than those running on current servers. Continue reading Facebook Introduces New Hardware for Use in Data Centers

Microsoft is submitting designs for its new server, Project Olympus, to the open source Open Compute Project eight months before it will be completed, in an effort to influence the data center market. By offering open source designs, the company pressures hardware manufacturers such as Hewlett-Packard to lower pricing of its own cloud infrastructure products. Among the new server’s key strengths are that it can use different international power standards without a need to tweak the hardware and can run a variety of applications. Continue reading Microsoft Releases its Server Design Early to Jumpstart Cloud

Retail and cloud giant Amazon has joined Google and Facebook in investing in development its own server chips. The company recently brought together a team of CPU architects and hardware development engineers, four of whom come from Calxeda, the defunct ARM-based server startup in Austin, Texas. Despite the high initial costs of custom server chips, these specialized products would allow Amazon to optimize costs and improve performance.
