Adobe Premiere Pro working station // Hardware and GPU

Hi' to all,

Now that we have egpu solution easily availaible and tested by the users, it would be nice to have a quick reference/survival guide for Premiere Pro hardware  :

Is Cuda still better than Open CL for Premiere Pro and AME ?

Does Cuda help for playback ?

It seems it can debayer RAW formats like R3D or cDNGs, but what about h264 ?

Is Encoding / decoding still only CPU ?

How does the RAM (not VRAM) impacts the playback or general use of Premiere Pro ?

Best RAM Setting in PP ?

How egpu is handled by Adobe Premiere Pro ?

What about computer already equipped with internal GPU ?

Will there be an option to choose GPU ? Use multiple GPU ?

Mixing AMD and Nvidia ?

Is TB2 too low to have an efficient use of PCIe Cards Or botllenecked bandwith ?

And what about TB3 ?

What is the best location for Media Caches ?

Separated drive should be better but what is best second option ? System drive (assuming it's an SSD) or on media drive ?

Is SSD storage good for handling large file ?

Do stripping SSDs on Raid 0 have a positive impact on speed ? On Sata/Pcie ? On TB2 or 3 ?

On the same computer Resolve have much better playback than Premiere.

Is due to GPU usage ? RAM usage ? CPU usage ?

What is better "performance" speaking ?

Video preview via Blackmagic or Kona video card ?

Video preview via fullscreen on a 2nd computer monitor

Thanks to all !
