Premiere Pro & After Effects
While these two applications often go hand in hand, Premiere Pro and After Effects utilize your system in slightly different ways. CPUs: Encoding and rendering previews are a CPU-intensive process, so the main control you have over export times is to have the fastest CPU possible. Both Premiere Pro and After Effects are lightly threaded during the encoding process. This means that, depending on the project, encoding can make use of four to eight CPU cores. Our overclocked, 9th Generation Intel® Core™ i7 Adobe Creative Cloud workstations are the fastest way to accelerate this process.
GPUs: A GPU of any type does not assist the actual encoding process (outputting a file to your computer), however, it can improve the processing speed of some effects prior to encoding. In some cases when exporting, the GPU is barely used for acceleration, if at all, when GPU accelerated effects aren't used.
Premiere Pro is the industry-leading video editing software for social sharing, TV, and film. Creative tools, integration with other apps and services, and the power of Adobe Sensei help you craft footage into polished films and videos. And with the Premiere Rush app, you can create and edit. Creative Cloud is a collection of 20+ desktop and mobile apps and services for photography, design, video, web, UX, and more. Now you can take your ideas to new places with Photoshop on the iPad, draw and paint with Adobe Fresco, and design for 3D and AR.

Multiple GPUs: Both applications won't see much benefit from multiple GPUs when scrubbing and editing footage in the timeline, but Premiere Pro can certainly benefit from multiple GPUs if your workflow makes use of the Mercury Playback Engine's GPU-accelerated effects and footage scaling.
