iMac 5k – i5 or i7 ???? NEED REAL people opinion

[Tommy Damani]

Just to confirm to everyone reading this in the future. Do not listen to anyone above. I’m now giving you REAL and ACTUAL experience instead of rubbish that people claim to know.

The new 5k iMac DOES NOT allow Premiere Pro to use the GPU for rendering. (Or vice versa, who cares?) Even installing CUDA did not activate the GPU, even adding the card name to the list of cards in GPUSniffer DID NOT activate the GPU. Rendering now takes 4 times as long as it did on my 2011 machine with the GPU activated. Whats the freaking point in getting a 2g graphics card if you can’t even utilise it?

When i opened up a project (first created in my 2011 iMac with GPU activated) in the new 5k iMac a pop up said:

MISSING RENDERER:
This project was last used with Mercury Playback Engine GPU Acceleration (OpenCL), which is not available on this system. Mercury Playback Engine Software Only will be used.

I’m now returning this unit to Apple and getting a full refund and then sticking with my 2011 unit.

What version of PPro are you using? Only certain video cards were supported in older versions of PPro and manually adding the card name to the list was just a hack that was never guarantied to work. I think starting with CS 6 or CC Adobe stopped approving specific cards and any card that had at least 1 or 2 gigs of VRAM.

That’s really unusual re: OpenGL not working with Premiere. I’m on a 5k iMac now and it purrs like a kitten – beautiful workstation actually. Using Premiere 2015.0, but OpenGL has worked since CS6 from memory.
