What does Chiplet mean?
A chiplet is a type of microprocessor component that organizes multiple cores into groups, in order to generate quicker microprocessor designs. As a group of cores, the chiplet works with other chiplets in an integrated circuit system to speed up data transmission and processing in a CPU.
Techopedia explains Chiplet
The chiplet build is dependent on multi-core design. As computers started becoming faster and faster, chip makers experimented with various ways to keep adding speed and efficiency. Eventually, systems moved from single core to multi-core design – two or more parallel cores would process information jointly. Now, in recent years, multi-core has really expanded as companies like AMD experiment with building chiplets into a synchronized multi-core system with dozens of cores.
Another way to explain the rise of multi-core is that it becomes easier for the company to design many parallel cores that will operate at a faster speed than a single core, no matter how well that single processor is crafted. There is also some controversy around chiplets and associated designs based on Moore's law – the law that the number of transistors on an integrated circuit can double continuously. Moore's law has contributed to dramatic increases in device speed and storage media capability, but it is not expected to last forever, and that is one thing that hardware makers are considering in today's multi-core environment.
