Rapidus CPU vs Intel CPU
Rpidus is a Japanese startup focusing on extremely fast, 2nm chip production, while Intel is an established manufacturer with a broader product range and different manufacturing priorities. Rapidus aims to differentiate with faster turnaround times (around 50 days) and high logic density, while Intel prioritizes performance per watt and uses backside power delivery (BSPDN), which results in a lower logic density on its 18A node but better efficiency.
Speed and agility in manufacturing, aiming for a 2nm process node.
Key Differentiator:
Promises significantly shorter production cycles, from the typical 120 days down to about 50 days, with potential for even faster "hot lots".
Transistor Density:
Reportedly matches TSMC's 2nm node and exceeds Intel's 18A node in logic density, achieving about 237.31 million transistors per square millimeter.
Status:
Aims for mass production by 2027, with a 2nm PDK (Process Design Kit) for customers by Q1 2026.
Challenges:
Technical feasibility for mass production and market positioning as a new entrant.
Manufacturing leading-edge chips, both for internal use and external customers, with an emphasis on performance per watt.
Key Differentiator:
Utilizes backside power delivery (BSPDN), which improves performance efficiency but results in lower logic density compared to nodes without it.
Transistor Density:
Lower than Rapidus and TSMC's 2nm nodes due to the use of BSPDN, with an estimated density of 184.21 million transistors per square millimeter.
Status:
Established manufacturer with a history of production. Intel's 18A node is a competitor in the advanced node space.
Challenges:
Faces competition and potential security vulnerabilities.
The choice between Rapidus and Intel depends on the specific needs of the chip.
Choose Rapidus if:
Speed and rapid turnaround time are the top priorities, such as for high-demand products.
Choose Intel if:
Performance per watt and energy efficiency are more critical than achieving the absolute highest transistor density.
