"WEBVTTKind: captionsLanguage: enit's been a long time I should not have left you without a back to the Mac episode two step two step two step two we can't wait get wicked how's the board ladies and gentlemen boys and girls this is chef Benjamin with nine-to-five Mac this is episode number 10 back to the mag yes there's been a little bit of hiatus but we are back talking about everything the Mac and I'm excited now to celebrate we're gonna talk about my favorite subject currently on the Mac and I'm gonna give you the Regas to figure out what that is no obviously not what do crickets have to do with the Mac yes EGP use obviously but in this episode we're gonna do things a little bit different so check it out now before we continue I just want to go ahead and remind you guys that the thumbs ups that you leave me it helped a lot so if you appreciate this video please thumbs up and also subscribe if you haven't done so and click that little bell icon so they should notify when new episodes there okay so let's get started this is the Sunnat e graphics breakaway box 650w it comes with an apple recommendation and it is the most powerful external graphics chassis that Apple recommends I already have one of these from a previous review but we just got another and that's going to allow us to use both of these external graphics boxes at the same time with our macbook pro if you haven't already seen our unboxing and review of the sunnat e graphics breakaway box you can check that out right here in the upper right hand corner now there is one thing this box doesn't come with a GPU inside already so you have to add your own card so what card are we gonna add we're gonna add the Vegas 64 well we've done that already what about the rx 580 no we've done that as well now this isn't the first time that I've attempted a dual EGP you set up on the map with DaVinci Resolve previously though it was sort of a hodgepodge sort of a mix match of GPU chasis and GPUs but now thanks to SONET for providing that extra break away about 650w and also special shout-out to AMD for providing to Radeon Pro WX 9100 professional workstation GPUs to test this with so I'm really looking forward to seeing the results so yep you heard right - Radeon Pro WX 90 100 GPUs based on the Vega 64 architectures so these are workstation grade GPUs each one has six mini DisplayPort connections and really these GPUs are aimed at professional workflows it supports 10-bit color and instead of eight gigabytes of HBM to memory like on the RX vega 64 it comes with 16 gigabytes of HBM to memory and again it's based on that Vega architecture so if you've used something like an Rx Vega 64 in the past then you'll have a ballpark idea as to what to expect from the WX 90 100 so let's get started let's head over to our MacBook Pro load up DaVinci Resolve studio which is the paid version of DaVinci Resolve it allows you to use multiple GPUs which is really cool so if you go to preferences and go to hardware configuration under system you'll see right now it's using the integrated graphics the plus graphic 655 from Intel so watch what happens when I play back this timeline or at least attempt to play back this timeline with effects so you can see the frame rate is like 2 frames per second on a 24 frames per second video so like 1.5 frames per second basically terrible performance you can see that the GPU is maxing out there on the GPU history on the Activity Monitor but we're gonna go ahead and try to export and render this video anyway and you can see one frame per second 1.5 frames per second it's painful folks and it's saying it's gonna take 4 hours and some change before this export is done so we're just gonna stop that because it's ridiculous to even think about it tempting something like that so do you see where I'm going with this we have 2 WX 91 hundredths right here in front of us we have 2 Thunder both 3 cables connected to the sunnat e graphics breakaway about 650 gonna plug those into my 2018 13-inch MacBook Pro load up DaVinci Resolve Studio 14 again and go right back to the preferences and start configuring this thing to use those GPUs so let's open up our test timeline go back to hardware configuration you can see right now it's using one of the video cards but I'm gonna set GPU processing mode to metal and GPU selection to manual and now I can selectively decide which GPUs I want to enable so I have both of them checked go to save I'm gonna close out of DaVinci Resolve and then open it back up again and now it should be utilizing both of those GPUs at the same time now watch what happens first of all we're gonna go back just to confirm yes it is using both alright now watch what happens when we play back this timeline I have my GPU history there so you can see what goes on alright so let's go to our editing page let's close out of the effects library close out of media pool and now let's move our playhead and start playing back and you can see folks right off the bat 24 frames per second playback speed real-time playback with tons of effects on the timeline and now we're going to try to export and see how it does so we're gonna make this a 4k export 4500 kilobits per second add it to the render queue start the render and now you'll see under the GPU history well first of all you see the frame rate is faster than real-time again 24 frames per second project it is exporting at about 27 frames per second or so give or take a frame or two so here are the statistics folks this is what you want to pay attention to notice that first chart DaVinci Resolve export no effects see what that Intel iris plus two thousand five hundred and twenty seconds five hundred and eighty-one with the dual WX 90 100 setup and then notice how crazy it is with effects 13,000 seconds 843 with that dual a GPU setup and twelve twelve with a single GPU so it definitely makes a difference having discrete graphics and then OpenCL you can see just how much of a difference in GPU makes having two of them basically doubles the performance run circles around that integrated GPU so here's where things get really interesting so I have the iMac Pro right and it's no slouch by itself with its own discrete figure 56 GPU so I am playing back three instances of DaVinci Resolve with effects on timelines you could see that the playback speed isn't real-time it's actually below so you're having some lag you're having some stutters on playback with all three of these it just isn't pretty now watch when I'm using the 2 WX 91 hundredths and I'm playing back all three of these timelines simultaneously real-time playback folks no lag no stutters I can move the playhead it resumes right off the bat so it makes a big difference even with the iMac Pro you're going to notice a difference especially when you start multitasking these GPUs are built with their asynchronous architecture to handle workloads like this playing it back with no effort folks and still have a little bit of headroom to go as you can see there in the GPU history so you could be exporting on one project editing on the other doing color on the other and you'll be good so folks as you just saw a GPUs can make a big difference in your workflow under certain circumstances for instance with DaVinci Resolve it can make our basale it can turn a 13-inch MacBook Pro from a machine that is basically unusable in certain situations we saw how slow it was with DaVinci Resolve exports when there were effects on the timeline and take that machine and make it something usable you can connect one two three even four GPUs to your MacBook Pro at the same time and really see the benefits in certain situations now obviously an e GPU isn't for everybody it isn't for every situation but it definitely seems like Apple is making a concerted effort to really support EGP use make it more of a mainstream thing in fact in the latest mojave beta that's coming out this fall you can now selectively drive individual applications on an app by half basis with external graphics and that's really exciting and even with pearl that really don't technically need additional assistance like the iMac Pro for instance we saw the benefits when we had to external graphics CH a C's connected to the iMac Pro it made it possible to work with multiple DaVinci Resolve projects at the same time maybe exporting in one project and editing the timeline and another and maybe doing color in another it really is a powerful tool to have at your disposal so if you appreciate coverage of eg if you use please let me know down below in the comment section if there's anything else you want to see regarding e GPUs leave that down below as well but we will have much more coverage in the future I can guarantee you that and who knows maybe we'll do a video about using for EGP use at the same time so thank you very much for watching this latest episode back to the Mac stay tuned next week because we have a very exciting show something I can't wait to show you next week I'll give you a little hint it's very fast this is Chet but 9 to 5 Mac youit's been a long time I should not have left you without a back to the Mac episode two step two step two step two we can't wait get wicked how's the board ladies and gentlemen boys and girls this is chef Benjamin with nine-to-five Mac this is episode number 10 back to the mag yes there's been a little bit of hiatus but we are back talking about everything the Mac and I'm excited now to celebrate we're gonna talk about my favorite subject currently on the Mac and I'm gonna give you the Regas to figure out what that is no obviously not what do crickets have to do with the Mac yes EGP use obviously
