  2. Enhanced Performance: The GAA structure of RibbonFET provides better control over the flow of current, resulting in improved switching speeds and reduced leakage. This leads to higher performance and greater energy efficiency.

  3. Scalability: RibbonFET is highly scalable, making it suitable for a wide range of applications, from low-power devices to high-performance computing systems. Its flexibility and adaptability make it a valuable addition to Intel's technology portfolio.

PowerVia: Revolutionizing Power Delivery

PowerVia is Intel's unique backside power delivery architecture. Traditional chips deliver power from the top side, but PowerVia introduces power delivery from the backside of the chip. This innovation improves standard cell utilization by 5-10% and boosts ISO-power performance by up to 4%. By optimizing power delivery, PowerVia enhances the overall efficiency and performance of the chip.

Key Advantages of PowerVia
  1. Optimized Power Delivery: PowerVia's backside power delivery eliminates the need for power to travel through the entire chip, reducing resistance and improving efficiency. This results in better power management and enhanced performance.

  2. Increased Utilization: By delivering power from the backside, PowerVia frees up valuable space on the top side of the chip, allowing for increased standard cell utilization. This leads to more efficient chip designs and improved performance.

  3. Enhanced Performance: PowerVia's optimized power delivery improves ISO-power performance, meaning that chips can achieve higher performance levels while maintaining the same power consumption. This is particularly important for high-performance applications that require both power efficiency and computational power.
