Advantages of using quicksync1/14/2024 It turns out that there is no difference in price, and hence the 2x performance advantage of Nvidia is completely offset by the price of one platform. Now that we know the maximum possible number of FHD (1920x1080) channels per server configured with integrated Intel graphics or the Nvidia video card, we can calculate the price per FHD channel from the known server prices. In this comparison, Nvidia has twice the performance of Intel at AVC transcoding and is almost as fast at HEVC transcoding. Transcoding AVC FHD 10 Mbps to HEVC FHD 5 Mbps 30 fps Transcoding AVC FHD 10 Mbps to AVC FHD 8 Mbps 30 fps These are results of a load test for the maximum possible number of transcoded channels (in the "fastest" mode). Maximum possible number of transcoded channels Integrated graphics Intel® UHD Graphics P630Ģ х 8 GB (dual-channel support is important) Let us now specify the platforms with the chosen graphics solutions. We have excluded older video card versions because they are guaranteed to lag in HEVC coding performance due to the missing B-frame coding capability. It is indeed possible to remove this limitation by installing a patch created by ingenious types on the internet, but, as we noted earlier, we will only consider a stable, proven, official solution. Our pick is Quadro RTX 4000 (8GB) which is a server counterpart for GeForce RTX 2070 Super (8GB) but, unlike RTX, it does not officially limit concurrent processing to 3 streams. With Nvidia, things are a little bit more complicated. With Intel, it is simple: we will just take one of the latest-generation Xeon Coffee Lake CPUs, Intel® Xeon® E-2246G processor, with an integrated Intel® UHD Graphics P630 GPU. We are only going to consider stable solutions that are capable of operating 24/7-this is a must in TV broadcasting. It is interesting to note that while technically being competitors in the field of video coding, both companies have been growing in parallel and even collaborating in the production of new chips.įirst, we have to decide what graphics hardware we are going to compare. This article discusses the main advantages and drawbacks of these solutions, using Intel’s QuickSync and Nvidia’s NVENC as examples. It can be fairly expensive to run it on the CPU, especially with the growth of OTT broadcasting, where there are multiple profiles per channel. Тranscoding video is a very resource-intensive task.
