2018 MacBook Pro with Vega 20

When exporting in Premiere Pro I noticed that it was not defaulting to the Vega 20 GPU and instead using the intel graphics. Is there a way to dictate to the 2018 MacBook Pro which gpu to use?

intel graphics performs better in video encoding than amd.

Could you please make the following benchmark with your Vega20? This would be very important for me and very thankful.

Thanks!

I'm not sure why you think the Intel chip performs better because when it comes to speed, the Vega 20 can blow that integrated chip out of the water.

When computers like the iMac Pro with the Vega 56 and Mac Pro with the AMD D700's do not have integrated graphics, its obviously works. I was hoping there was a terminal code out there than could change the way Adobe looks at the graphics card bus and default to the Vega 20 in this case... just like macOS can when an eGPU is plugged in.

@corran9hal Intel chips have dedicated video encoding/decoding hardware (QuickSync), and for a while now iMacs (normal ones) were quicker than Mac Pros due to the I-series CPUs having this, while Xeons not. Exception of course is for H265 and T2 systems where the latter handles the codec instead of Intel (making it even faster). So no, the Vega 20 likely won't blow Intel out of the water in this regard. Gaming and rendering, sure.

Are you saying the Intel UHD Graphics 630 chip is faster at exporting or rendering than the Vega 20?

At encoding videos, yes. For anything else the Vega 20 is obviously far superior.

Sorry, but how do you enable quick sync or is that automatically done if you are using any formats that support it?

Yeah, I'm at a loss because it seems this quick sync feature only applies to PC which is helping on this MacBook Pro and I'm seeing much slower render times when it's using the Integrated graphics chip. I don't even know how he's getting his numbers because my root issue was Premiere Pro or Media Encoder would not use the Vega 20 when rendering or exporting... so how did he test it?
