performance optimisation across various media applications and frameworks. Intel Quick Sync Video Intel Quick Sync Video is a hardware transcoder built into many generations of Intel Core processors and into Intel Data Center GPU Flex Series. VisualOn Optimizer easily integrates with Intel Quick Sync Video, dynamically adapting Intel Quick Sync Video transcoding parameters using AI methods to optimise the video data based on each frame. This integration makes VisualOn Optimizer an ideal choice for media encoding operations. Using Optimizer with Intel Quick Sync Video, transcoding for different content delivery methods can run quicker, use less bandwidth and decrease storage requirements—while enhancing visual quality. Benchmarks and Testing Extensive testing by VisualOn shows how Optimizer performs compared to other CAE solutions and how it enhances Intel Quick Sync Video encoder running on Intel CPUs and Intel Data Center GPU Flex Series. All the following benchmarks were conducted by VisualOn.
Intel Xeon Scalable processors also provide improved power efficiency and TCO with platform enhancements like DDR5 memory and PCIe 5 support. Enhanced security features include Intel® Software Guard Extensions (Intel® SGX) and Intel® Total Memory Encryption to ensure comprehensive data protection. This family of high-performance CPUs is a solid foundation for encoding and other workloads in the data centre, at the edge, or in the cloud. Intel Data Center GPU Flex Series Leveraging the Xe-HPG microarchitecture, the Intel Data Center GPU Flex Series— with Intel Quick Sync Video— offers flexibility and efficient scaling to develop and run a range of powerful media processing and delivery and media- based AI inference solutions. With two GPUs each with eight Xe cores and four media engines per GPU, this series delivers outstanding compute density and energy efficiency for media and visual workloads. With support for multi- instance GPU (MIG) technology, the Intel Data Center GPU Flex Series allows multiple workloads to run simultaneously on a single GPU. The GPUs are built for power efficiency to help reduce overall energy footprint in data centres. They are backed by the Intel software and driver ecosystem, ensuring compatibility and
Optimizer on Intel® Xeon® Scalable Processors and Intel Data Center GPU Flex Series with Intel Quick Sync Video Using the Intel® Video Processing Library (Intel® VPL) together with FFmpeg, VisualOn integrated Optimizer to accelerate performance and improve efficiency on Intel technologies, including 4th Gen Intel Xeon Scalable processors and Intel Data Center GPU Flex Series with Intel Quick Sync Video built in. Intel VPL Intel VPL presents a unified programming interface for video processing and encoding across a variety of hardware - CPUs, GPUs, and other accelerators - simplifying development efforts and reducing time to market. Intel VPL helps accelerate building and running high- performance, portable media pipelines. It provides device discovery and selection in media centric and video analytics workloads, and API primitives for zero- copy buffer sharing. Intel VPL supports a wide range of video formats, resolutions and features, making it versatile for different video processing needs. 4th Gen Intel Xeon Scalable Processors For CPU-based encoding, Intel Xeon Scalable Processors deliver scalable performance with up to 56 cores per CPU and built-in Intel® AI Accelerator engines, such as Intel® Advanced Vector Extensions 512 (Intel® AVX-512). Intel AI Accelerator engines provide dedicated AI functions built into the silicon that enhance performance for specific AI and complex computing tasks. Intel AVX-512 extends vector processing capabilities with wider vectors, a new extensible syntax and richer functionality. With ultra-wide 512-bit vector operations, Intel AVX-512 can handle the most demanding computational tasks while reducing the energy needed to complete them. Applications can pack 32 double- precision and 64 single-precision floating point operations per clock cycle within the 512-bit vectors, as well as eight 64-bit and sixteen 32-bit integers.
