The size of Wafer Scale processor Cerebras Engine is huge by today’s standards
The last 60 years in the semiconductor industry engineers tried to make the chip as small as possible, and it has yielded great results. But the startup Cerebras Systems engineering turns this idea on its head. Their development represents a giant by modern standards, a Wafer Scale processor Cerebras Engine 8×8 inches (mm 203х203) is at least 50 times more than equivalent chips in use today. In size it is more similar to the iPad.

According to founder Andrew Feldman, the logic is very simple. Software artificial intelligence requires a vast amount of information for improvement and learning, so the processor should be as fast as possible to handle all this data – even if it means using massive components.
Cerebras Wafer Scale Engine size is comparable to iPad
The chip was developed by company Wafer Scale Engine was so massive for a reason, because it has a 1.2 trillion transistors 400 thousand cores and 18 GB internal memory SRAM. For example, a desktop processor for your home computer will have 2 billion transistors on a chip, 4 to 12 cores and cache memory in tens of megabytes.
Created the CPU for half a million hryvnias on what he is capable of
“The biggest constraint of the modern systems of artificial intelligence is that learning the software takes too much time. Therefore, every square millimeter of the processor-titanium is optimized to work with AI, what its speed is getting crazy fast,” explained Andrew Feldman.

In contrast to the conventional method of etching of individual chips on wafer Cerebras uses the entire plate as a single massive chip that allows individual cores to communicate with each other directly. To deal with the inevitable manufacturing defects that arise when making such a huge chip, the company added additional kernel as a backup.
Explosive power: Intel has unveiled the next-generation processors
Cerebras Systems has already started to put Cerebras WSE to its customers. The company will not sell them separately, and plans to offer servers based on these chips. The cost of new items not yet reported.
Earlier, Intel is preparing the tenth generation of processors with an unpleasant surprise. Also we reviewed the powerful smartphones of 2019 on the Snapdragon 855.
