![]() ![]() The technology can split the workload of video compression between a GPU that is integrated with the CPU and one that is in a discrete graphics card. The firm has a new technology that it calls Intel DeepLink Hyper Encode. However, it comes at the expense of a 20-fold increase in compression time. For example, Fraunhofer’s VVC codec is said to be able to deliver similar quality to HEVC at half the bit-rate. While each generation of codecs gets more efficient at improving quality or reducing bitrates, the trade-off is that the complexity of encoding, especially, gets more complex. We had a bit of a dig into the AV1 encoding aspects of this news. The first PC to have the GPU as an option is the Galaxy Book2Pro (which uses a 13.3” or 15.6” FullHD OLED) but other PC brands will follow. Jon Peddie said that the system blurs the edges of the new overlapping frame using a dithering filter. It has a feature called Smooth Sync used when there the display frame rates do not match the frame rate of the GPU to minimise the ‘tearing’ effect.It has less distortion than H.264 at the same bit rate. Intel sees AV1 as being able to support game streaming.Alternatively, when products are available in the market, it will support DisplayPort 2.0 1080P and 1440P displays can be driven up to 360Hz. The Arc Xe display engine can support four UltraHD 120Hz displays over HDMI 2.0b or DisplayPort 1.4a or dual 8K 60Hz displays.There’s a video here and Intel said that the new GPU is 2.35X faster at upscaling than its previous Iris Xe integrated graphics processor (using Topaz Labs Video Enhance AI) It has new supersampling that supports AI-enhanced upscaling.The Xe Media Engine is said to be optimised for 8K workloads with AV1 up to 8K with 10 bit HDR.The encode feature is said to be 50X faster than software implementations and Intel claims to have a way to ‘gang up’ the video processors to bring them to bear on an encoding process. The chip is said to be the first to support hardware encoding and decoding of the AV1 codec.Intel announced its new discrete Arc GPU for notebook use now and with desktop and workstation implementations coming during this year.
