Enabling AMD RX 4XX cards in Sierra.

[neacsuc]

Try inject Intel and not injecting ATI. There is no crossfire support in OsX but you can double your open CL scores/performance in apps like Luxmark Ball benchmark.

View attachment 228881 this is an old bench with 2 RX 480s

do you know if there is any difference in performance in FCPX using two cards?

I did those 3 find and replace and I couldn't restart it had kernel panics I guess connected my wd external backup hdd went into bios and set my external clone backup drive and booted back into backup drive and changed the file back to original in the ssd Sierra drive ..now I have system back I don't know what did I do wrong ;-(

Tested this method on 12.1 from my backup, Works well. Luxmark now shows 36 cores active. but for some odd reason clock shows 130mhz both in 12.1 and 12.2.

Anyone tested the RX470/480 in a 5K setup with perhaps the Dell Ultrasharp UltraHD 5K-Monitor (UP2715K)?

The RX 470-480 I believe is only capable of 4K 30hz with HDMI, 4K 60hz DisplayPort. No 5k yet and it may not have it in Windows either. Vega 10 should be coming soon (3-6 months) it should have 5k support since it's in Sierra I would imagine retina screens will require it.

I hope, new iMacs comes out with rx470 and rx480 for 5K display, Mac Pros comes out Vega10 and Vega 10X2.

I have Gigabyte RX480 4GB, and I tested on Sierra and WindOHws 10. In my opinion RX480 Performance under 70% of its capabilities on Sierra. On Windows much much much better.

Unfortunately new version of Sierra PB 3 (released today) hasn't contain any changes for Dayman.

SO, yeah. If Apple will ship Polaris 10 drivers (Dayman framebuffer) for rx470 and rx480, capable to use 5K display nicely. It's not a question... in the future... maybe...

Sorry for my english..

In Windows are you using integrated (igpu as primary) or dedicated card graphics?

I turned off Integrated Graphics. Just RX480
