AMD claims a new Premiere Pro update can get better 4K video exports out of some Ryzen 4000 notebooks
Newer versions (14.2 and up) of Adobe's Premiere Pro include hardware-accelerated encoding support for AMD GPUs on Windows. It may make work on videos in the H.264 or HEVC formats faster and more efficient on PCs with integrated Radeon graphics. Therefore, this update may make notebooks with Ryzen 4000 U- or H-series processors and RX 5000-series graphics a better fit for some creators.
AMD has posted some research to this effect on their blog. It claims that exporting the same 4-minute extremely high-quality (Apple ProRes 4444 4K/60fps) video clip in QuickTime to Premiere Pro's H.264 4K YouTube preset took up to 29% less time on the Lenovo IdeaPad Slim 7 with the AMD Ryzen 7 4800U and non-discrete graphics compared to the same APU on its own.
Similarly, the HP Envy x360 13z 2-in-1 with the Ryzen 5 4500U exported the same up to 25% faster, whereas the Envy x360 15z with a 7 4700U was 26% faster. The 7 4800H/Radeon RX 5500M MSI Bravo 17 was 35% faster, whereas the Dell G5 15 Special Edition with a 7 4800H processor plus RX 5600M graphics made 43% gains over the processor alone.
