C200: Still no love from Adobe... (Premiere Pro 12.0.1 update)

Turbo boost is not that great like it looks like on a paper. Since only one core from all cores is turbo boosting and this frequency is more or less teoretical. Frequency depends on ability to cool processor. iMac has great cooling so I suppose it should be close but not exavtly there. Of course, this applies only if you are looking into single core performace.

Well actually it works differently than you described. All the cores can and will turbo boost, but the maximum boosted clock speed drops as more cores are boosted / in use.

Yes definitely not so huge improvement compared to your 2013 Mac Pro, probably substantial only in really long batch conversions. As we see it seems that CRD can use powerful OpenCL GPU quite effectively.

What GPU's you have on your Mac Pro, is it 2 x D700 Firepro?

I have the D500s GPUs in my Mac Pro. I've also ordered an iMac Pro, with the same configuration as yours. Are you using an external array with yours? I have a Pegasus2 from Promise that I use currently. I'm tempted to just keep using it with the new computer, via a Thunderbolt 3 to Thunderbolt 2 adapter. Part of the reason to keep the old one is that I have a long optical Thunderbolt 2 cable for my array that lets me keep the array in a closet 10 feet away. I haven't seen any long Thunderbolt 3 cables, so if I got a new array, I'd have to put up with having the noise closer to me.

Yes, I have original Pegasus and it works like charm via thunderbolt adapter. Actually I just replaced my old Pegasus 6x2TB drives with 6x4TB ones.

Coming back to this, now I've got a new computer. What drives did you order for the Pegasus2? How did you do the switch? One by one or all at once (i.e., destroying, then rebuilding the array)?

Hello and sorry for this somewhat slow reply on your question.

I have these Toshiba 4TB drives installed now on my Pegasus: https://www.amazon.com/Toshiba-4-0TB-MD04ACA400-7200rpm-Internal/dp/B00APWA9FY

Its compliant disk according to Promise's newest compatibility list for the original Pegasus R6, some other 4TB drives might work also (one not in the list) but since I was buying quite many at once (7 in total) I wanted to ensure that the new drive setup will work 100% from the first try.

There is also some Seagate 4TB drives in the Promise compability list, but I skipped those since I have some sad memories from using seagate non-raid drives in raid setup in the past.

About the upgrade process, I did go with switching all drives at once (Backup old array –> old drives out –> new drives in –> build new array). I understood that it could be done drive by drive but would take ages to complete. And I had some extra terabytes where to empty the old array in between.

Edit: My Pegasus is not the series2 one. It's the original first model. For the Pegasus2 that you have there might be even better 4TB (and beyond) options for the disk compability, check Promise supoort site for more info.
