iSIZE, a pioneer in deep learning for efficient and sustainable video delivery benchmarked the performance of its BitSave and BitClear software running on the new 4th Gen AMD EPYC™ CPUs. iSIZE deploys at-scale AI-based video pre-processing and de-noising technologies across a range of CPU and GPU-powered deployments in data centers and captive environments.
Using 4th Gen AMD EPYC processors, running real-world tests to accelerate the neural network inferences in BitSave and BitClear, iSIZE achieves on average (across different resolutions) for VOD a performance boost of over 3x, and for live of over 4x, compared to the previous generation AMD EPYC™ CPUs. This translates directly to greatly enhanced efficiency for users. For example, iSIZE BitSave technology can enable nearly 5 times more 4k channels than on the previous generation.
“The significant advances in performance and efficiency in the new 4th Gen AMD EPYC processors allows us to deliver better runtime efficiency for both VoD and live processing, which in turn enables more streams with a single socket CPU and is significantly better value for our customers,” explained Yiannis Andreopoulos, CTO and co-founder of iSIZE. “This is a significant improvement in our continued mission to improve bitrate efficiency, quality and sustainability for online video delivery.”
BitSave is a deep perceptual pre-processor that runs before the conventional video compression stage in order to make encoding significantly more efficient in terms of bitrate at the same or improved visual quality. Being a codec and content agnostic solution, BitSave also allows the encoder to be used with simpler encoding recipes, thereby making it faster, saving data center cost and significantly improving the sustainability of video streaming. It requires no changes to the encoding, delivery or decoding devices and can run in real-time on CPU and GPU hardware.
BitClear is a video de-noising solution that uses iSIZE’s image perception processing to remove compression artifacts from video during transcoding. Video content that has been through multiple transcoding iterations can be revived to the best possible quality. It is the first technology of its kind that can run in real-time on CPU or GPU hardware.
“Building on the record-breaking performance of 3rd Gen AMD EPYC processors, the latest 4th Gen AMD EPYC processors help our customers achieve better business outcomes faster and address their most ambitious energy efficiency goals. Our new “Zen 4” architecture is optimized for modern workloads and delivers the core density, memory bandwidth and sophisticated security features customers demand,” said Ram Peddibhotla, corporate vice president, EPYC product management, AMD.
