Hi everyone,

I'm a motion designer using mostly After Effects, Premiere, and Maya. I bought about a month ago a sonnet 550w with an RX 580 8GB in it. I'd like to improve the render time of my set-up. My plan is to buy/wait for the Radeon VII which will be released early FEB if I'm not mistaken. Is it worth it? Are my Sonnet and my Mac going to be compatible with that gpu? Should I buy a Vega 64 instead?

Thanks a lot in advance for your help!!  🙂

The Radeon VII will have similar power demands as the RX Vega 64. Therefore you'd need a 650W+ power supply. In my opinion, getting an RX Vega 56 will be the best choice given its current price, performance in macOS, and your Breakaway 550.

Is this a fact or an educated guess?

Thanks, I'll go for this option instead then! And yes apparently, the new Radeon will have similar power demands. I saw that in one of Linus Tech Vids recently.

I have 2 Sonnet 550w with Radeon Frontiers and have no issues at all even running stress tests using a 2018 Mac Mini.
I've heard that if you are also trying to charge a laptop then the 650w is a must.

I am glad I found your post as I am in a similar situation wanting to improve rendering speed with Maya and related software.  I am curious if you have completed your setup and have some results you could share.

I have a 2017 Touch Bar MacBook Pro with the best video card you could get at the time in it.  I have installed Mojave which I believe now allows you to specify the use of an external GPU.   I have not found anyone that can confirm if Maya takes advantage of the external GPU or if it just uses what ever the MBP is set to use, thus with Mojave it should.

I believe I should also go with a 650w box so it can charge my MBP at the same time. 

Any insight you have would be greatly appreciated!
