Core Viewpoint - The PCI-SIG is developing the PCIe 8.0 specification, which aims to continue the trend of doubling total bandwidth with each generation, potentially offering up to 1 TB/s bidirectional transfer rates in the future [2][5][9]. Group 1: PCIe 8.0 Development - PCIe 8.0 is currently in draft version 0.3, with expectations to provide eight times the bandwidth of current high-end PC components [2][4]. - The specification aims to maintain the trend of doubling bandwidth seen from PCIe 1.0 to 7.0, with PCIe 8.0 expected to achieve 256 GT/s [4][5]. - The development of PCIe 8.0 includes exploring fiber connector technology to achieve faster speeds while ensuring low latency and reliability [7][8]. Group 2: Bandwidth and Performance - Current consumer PCs typically use PCIe 3.0 or 4.0, supporting 8 GT/s and 16 GT/s respectively, with maximum bandwidths of 32 GB/s and 64 GB/s [4]. - PCIe 5.0 supports 32 GT/s, achieving up to 128 GB/s, while PCIe 6.0 can reach 64 GT/s and 256 GB/s [4]. - PCIe 7.0 doubles these figures again, reaching 128 GT/s and 512 GB/s, with compliance plans set for 2028 [4][5]. Group 3: Applications and Importance - PCIe 8.0 is expected to play a crucial role in supporting demanding workloads in artificial intelligence, machine learning, edge computing, quantum computing, and large-scale data centers [9].
