The PCoIP Ultra enhancements in the latest release exhibit some worthwhile network bandwidth savings for video workloads across the spectrum of image quality settings, mostly due to optimizations in our pixel block structures and differential encoding efficiencies. While I can’t repeat the 4K video test using SSE4.2 because AVX2 or NVENC is required to achieve 24 fps on a 4K/UHD display, I ran some benchmarks comparing a 24 fps workload on a standard 1920 x 1080 FHD display: How does network bandwidth compare to traditional SSE4.2-based PCoIP encoding? You can look forward to quality metrics in a later posting.

With the Ultra enhancements, the quality can be now be dialed way beyond Q90 in a continuous fashion for remarkable reproduction where color accuracy and distortion-free playback are paramount. This ability to scale image quality has always set the PCoIP protocol apart from alternative remote desktop technologies. Note the default image quality for PCoIP Ultra remains at Q80 as before, which approaches perceptually lossless in many cases, although discerning artists in the media and entertainment industry often select Q90 to eliminate any compression guesswork. Using the same infrastructure as the CPU tests in the previous post, here is the network bandwidth consumption for Big Buck Bunny 1080p and 4K/UHD at 24 fps:

Spoiler alert - some awesome improvements to see! In this article, we’ll look at network bandwidth for video workloads at different quality settings as well as bandwidth efficiency compared to PCoIP-SSE4.2. So far, this technical blog series has explored the architecture of the PCoIP Ultra enhancements and how multi-core CPU scaling works for 4K/UHD video workloads.
