Every time you get a purchase recommendation from an e-commerce site, receive real-time traffic updates from your highly automated vehicle, or play an online video game, you’re benefiting from artificial intelligence (AI) accelerators. A high-performance parallel computation machine, an AI accelerator is designed to efficiently process AI workloads like neural networks—and deliver near-real-time insights that enable an array of applications.
For an AI accelerator to do its job effectively, data that moves between it (as a device) and CPUs and GPUs (the hosts) must do so swiftly and with very little latency. A key to making this happen? The PCI Express® (PCIe®) high-speed interface.
With every generation, made available roughly every three years, PCIe delivers double the bandwidth—just what our data-driven digital world demands. The latest version of the specification, PCIe 6.0, provides:
- 64 GT/s per pin data transfer rate
- A new low-power state for greater power efficiency
- Cost-effective performance
- High-performance integrity and data encryption (IDE)
- Backwards compatibility to previous generations
While PCIe might traditionally be associated with slots on PCs that enable connectivity with peripheral devices such as graphics cards and scanners, it is so much more thanks to its increasing bandwidth. Read on to learn more about how PCIe supports the demanding requirements of AI accelerators.
