PCIe Gen 4
Delivers high-speed data transfer with increased bandwidth for demanding applications.
Overview
PCIe Gen 4 is a cutting-edge high-speed interface standard, offering a data transfer rate of 16 GT/s per lane and enhanced bandwidth. It provides up to 32 GB/s in each direction, making it ideal for performance-intensive applications.
This versatile technology supports high-performance computing, AI, gaming, and cloud solutions, along with NVMe SSDs, networking, 5G infrastructure, and more. Its scalability and backward compatibility ensure broad system adaptability.

PCIe Gen 4 Architecture
Key Features
Increased Data Transfer Rate: PCIe Gen 4 offers 16 GT/s per lane, doubling the data rate of PCIe Gen 3. This enables faster data exchange, improving performance for high-speed applications.
Higher Bandwidth: Each PCIe Gen 4 lane provides 2 GB/s of unidirectional bandwidth, and an x16 configuration can achieve up to 32 GB/s. This enhances the system’s ability to handle large, data-intensive tasks.
Backward Compatibility: PCIe Gen 4 supports devices from older PCIe generations (Gen 1, Gen 2, Gen 3). Older devices will operate at their maximum speeds but still work in PCIe Gen 4 slots.
Lower Latency: PCIe Gen 4 reduces latency in data transfer, ensuring quicker responses for real-time applications like AI, gaming, and high-speed networking. This enhances the overall system performance.
Enhanced Power Efficiency: It introduces improved power management features, reducing idle power consumption. This balances performance with energy efficiency, ideal for devices with high power demands.
Improved Signal Integrity: Enhanced equalization and channel modeling minimize signal degradation at high speeds. This ensures stable and reliable data transfer, even over long distances or complex PCB layouts.
Scalability: PCIe Gen 4 offers flexible lane configurations, including x1, x2, x4, x8, and x16. This scalability allows systems to customize bandwidth based on performance requirements.
Compliance: PCIe Gen 4 adheres to PCI-SIG’s 4.0 specification. This ensures compatibility and interoperability across different vendors and devices, promoting seamless integration into various systems.
