Intel’s silicon-based virtualization technology optimizes the performance of software-defined vehicles (SDVs) by efficiently navigating through the hardware, similar to an electric vehicle (EV) on a road trip from Point A to Point B. However, deviations to alternative locations (Point C) can result in energy consumption and longer journey times, similar to the performance degradation seen with other silicon vendors.
Comparing SR-IOV and VirtIO, SR-IOV offers a robust, high-performance, and cost-effective hardware-based virtualization solution that eliminates the risks associated with VirtIO’s virtual-only separation. With Intel SDV SoCs using SR-IOV, workloads are separated at the GPU silicon level, freeing up software layers for improved performance and functionality without added latency. In terms of security, SR-IOV is better equipped to defend against risks by leveraging hardware virtualization capabilities, whereas VirtIO presents a larger attack surface within the virtualization layer, potentially compromising the security of the operating system.
By utilizing Intel’s silicon-hardened virtualization capabilities, Automotive Intel can provide the industry with a more efficient and higher-performance approach to designing SDVs, achieving approximately 99% efficiency with zero additional latency. For example, in a benchmark test using GFX Manhattan 3.0, the Intel-based SR-IOV GPU demonstrated 99% efficiency in operating a single workload compared to VirtIO’s 43% efficiency, with zero latency for 100 frames per second (fps) workload with the Intel solution compared to additional workload-dependent latency with VirtIO.
Overall, Intel’s SR-IOV technology outperforms the competition in terms of efficiency, performance, and security when it comes to powering SDVs. By leveraging hardware virtualization capabilities, Intel is able to deliver a more streamlined and secure virtualization solution for software-defined vehicles, optimizing performance and functionality for a smoother journey on the road.
