- Intel’s implementation of backside power delivery, called PowerVia, provides a 6% boost in chip frequency and improves power efficiency.
- TSMC is planning its own backside power delivery implementation, but is 6-12 months behind Intel.
- Intel’s success with the Intel 18A process and PowerVia technology demonstrates the company’s innovation engine is back on track.
- Intel is scheduled to launch the Intel 14A process in 2027, which will feature High-NA EUV lithography, potentially putting the company ahead of TSMC again.
Introduction to Backside Power Delivery
The launch of Intel’s Panther Lake CPUs marks a significant milestone in the company’s efforts to compete with TSMC. One of the key features of these CPUs is the use of backside power delivery, a technology that moves power wires to the back side of the chip, leaving interconnects on the front side. This design change is crucial for improving the performance and efficiency of modern chips, which have become increasingly dense and complex. By separating power wires from interconnects, backside power delivery reduces interference and enables chips to run faster and more efficiently.
The Benefits of Backside Power Delivery
Intel’s implementation of backside power delivery, called PowerVia, has already shown promising results. In early testing, PowerVia enabled a 6% boost in chip frequency, which means that chips can run faster using the same amount of power or use less power while delivering the same performance. This is particularly important for use cases where power efficiency matters, such as in laptops and mobile devices. With Panther Lake laptops shipping later this month, millions of devices will soon be equipped with PowerVia technology, demonstrating the significant impact of this innovation.
TSMC’s Response to Backside Power Delivery
TSMC, the foundry leader, is also planning its own backside power delivery implementation, called Super Power Rail. However, the company is well behind Intel, with its A16 process node, which includes Super Power Rail, not expected to enter production until the end of 2026. This gives Intel a head start of 6-12 months, which could be significant in the highly competitive semiconductor industry. While TSMC will eventually catch up, Intel’s early mover advantage could provide a significant boost to the company’s foundry business.
Innovation at Intel
The success of Intel’s PowerVia technology and the launch of the Intel 18A process node demonstrate that the company’s innovation engine is back on track. After years of struggling to keep pace with TSMC, Intel has finally taken the lead in a key area of semiconductor technology. This is a significant achievement, and it bodes well for the company’s future prospects. With the Intel 14A process node scheduled for 2027, which will feature High-NA EUV lithography, Intel is poised to stay ahead of TSMC in the coming years.
Future Prospects for Intel
The launch of the Intel 18A process node and the success of PowerVia technology have significant implications for Intel’s foundry business. As the company races to find external customers for its foundry, its trailblazing with backside power delivery and High-NA EUV could help turn the struggling foundry business into a long-term success. With its innovation engine firing on all cylinders, Intel is well-positioned to compete with TSMC and regain its position as a leader in the semiconductor industry. As the company continues to push the boundaries of semiconductor technology, it will be exciting to see how its competitors respond and how the industry evolves in the coming years.
