AMD cards are about two times slower than equally priced nVidia cards as far as PR goes. The video card makes no difference in AE, since AE has no hardware acceleration.
So I would genuinly be beter off buying the old iMac with the NVIDIA GeForce GTX 780M in place of the 5K iMac and the AMD Radeon R9 M295X? And hence forgetting the Thunderbolt 2......
I also use Capture One and Photoshop a lot, do you know what affect the card has on those progams?
Thanks for the responce!
Read the Beware box here: Tweakers Page - What video card to use? to see where a video card kicks in.
Thunderbolt is the only sensible connection for raids on Mac's, unless you go for external storage and a dedicated Areca controller.
I guess you will profit more from the Peg Promis R8 than from the video card.
Facinating! Makes me want to ditch the iMac and get a PC... Wish apple gave you a little more choice.
I do find it amazing that even the new mac pro with Dual AMD FirePro D700 GPUs with 6GB of GDDR5 VRAM each (well over 6k) would strugle to keep up with last year's iMac with the GeForce (well under 3k).
Do you think Adobe will bring out suport for the cards as they don't support a single top line iMac or Mac Pro anymore?
Though it's intresting you think I'd benefit more from Thunderbolt 2 with an AMD than Thunderbolt 1 with the GeForce.
Next question if I have 'a man' that will swap put the new AMD card for the old GeForce card will I experience other problems down the line, is that s really bad idea?
Sorry, I misinterpreted you. I thought the option was nVidia and no Thunderbolt versus AMD and Thunderbolt 2.
The difference between Thunderbolt 1 and 2 is not that big in practical performance and with 8 HDD's in the PEG, you will not even use the full bandwidth of Thunderbolt 1, let alone Thunderbolt 2. If the PEG is populated with SSD's, then Thunderbolt 1 is about as fast as 2 SSD's in raid0 and Thunderbolt 2 is around as fast as 3 SSD's in raid0. Adding more SSD's in the PEG will not improve performance. That is the practical limitation of Thunderbolt.
With HDD's in the PEG, I think Thunderbolt 1 and nVidia is preferable, but maybe that is offset by other improvements in the new iMac.
All very good to know... Wish I had the cash to fill a PEG 8 with SSDs that would be insane (and aparently pointless)!
But just to be clear, will the Mercury Playback work with the AMD card?
Anyone with the new 5K iMac out there that uses PP?
