@kelvin_tan yes i used the official driver, i just tested Assassin's Creed Odyssey and didn't see any great improvements compared to Vega 64, maybe a driver bug, or something but running at Ultra high settings i'm getting 38-44, sometimes 50 (doesn't happen that often).

Assassin Creed Odyssey is bad on TB3 egpu setting, like Forza Horizon 4 it’s limited by TB3 bandwidth. It renders too much things and layer most probably drm protection takes a lot as well. My 2080ti egpu, couldn’t  manage smooth max setting on this title.

@oliverb even attempting to modify, reverse-engineer, or patch systems is prohibited (read Apple’s SLA). So no it’s technically not allowed. In a simplistic sense, distributing a modified file is blatant, whereas telling you - “hey you could do so-so and get this going” is “more ok” because you then do it personally. We have to skirt on a fine line - idiotic though it may be haha. From a time when eGPUs weren’t even a thing (Sierra), we have come far at least. Let’s hope we can cross the line for NVIDIA eGPUs on macOS.

@kelvin_tan That's not allowed unfortunately - but the mod is easy to do. Also IIRC @itsage tested previous betas of 10.14.4 as well, and those didn't work, so it's unlikely 10.14.3 would.

Hey thanks for the sound off, was just disinclined to install 10.14.4b3 for everyday use. Will wait till it officially drops then.

Meanwhile thanks for all the efforts in getting the Radeon to run and also excited to see the numbers. Finally something to drive my ultrawide 1440p @ respectable numbers for 3D. Cheers!

@joi_kansai i agree with Odyssey, but Forza Horizon 4 is giving me great performance gains compared to my Vega 64, it used to be at 38-44 to 53-60 running at 3440x1440 Ultra settings.

@juan_c_yunis IMO the entire recent Assassin’s Creed releases are crap on AMD. A 1070 delivers V64 like performance in Odyssey (which I ironically got as a bundle with the V64).

@mac_editor i know, funny thing is that Odyssey is supposed to be optimized for Radeon lol, my dedicated gaming PC with Core i7 8700K + GTX 1080 Ti runs it at 4K 50-55fps. Origin on the other hand runs smoother.

Vega 64 like that game 🙂 I think i saw earlier on some desktop benchmarks in amd forum or somewhere, i forgot, it beats 1080ti when I’m not wrong.

Hi Folks, 
it's the first time I write here. But I have been reading the forum for a long time.

I'm thinking about getting an eGPU Setup. I would like to use the internal Display of my IMac 27 5k 2017 i5 7600k Radeon Pro 580. That should be possible, right? After all I've read in this forum, this means a reduction of gpu power by 30-35%. The Razer Core X should be the right enclosure for me. Now I have to decide between a Vega64 Sapphire Nitro+ or a Radeon VII. The Vega64 is currently available for 440 €, the Radeon VII costs 300 € more. In terms of performance, compared to my current igpu RP 580, is the vega64 worth it?  How much more gpu power could I expect? Or should i go for the Radeon VII? Im a architect and using ArchiCAD, CS6, Render Programs... And somtimes im a gamer too. 
Sorry for my english.  😕

Welcome to the forum, well if you use it for work 16GB comes handy, and it kinda helps you up to future proof your setup, also if you are a gamer they include 3 games worth of $180, and VII is about 30-40% more powerful than Vega 64.

Thank you for your fast reply. How much more power would the Vega64 have compared to the my RP580? Minus the power consumption through the internal display...

Vega 64 is still very powerful, compared to the RP580 i would say a lot, but take a look at this website:  https://gpu.userbenchmark.com/Compare/AMD-RX-Vega-64-vs-AMD-RX-580/3933vs3923  

But yeah the TB3 bandwidth is limited and also you are using the internal display but i think it would be a lot, wouldn't make that much of a difference if you are switching from RP580 to RX580, but even switching to a Vega 56 would be pretty good increase.

Mhmmm, the Radeon Pro 580 is more like a RX 570...in my opinion. 

https://www.techpowerup.com/gpu-specs/radeon-pro-580.c2968

But okay, Vega64 is 98% faster than a RX570. Minus 35% for using the internal display = 60-63 faster than a RX570. Is this a good upgrade for 440€ + 300€ for the Enclosure?! Don't forget, gaming in mac osx is also slower than windows 10 right?! But i don't like Windows, looks ugly.  😆

macOS isn’t slower. Porting, OpenGL and other factor can slow down.
good porting like Feral ones, which support Metal 2 gets you same performance on Windows.

@itsage and everyone else,

Okay bit the bullet, installed 10.14.4b3 (after a CCC backup), and injected the PCI ID into AMDX5000.kext. The Radeon VII works with the Razer Core X, but my numbers seems low:

LuxMark v3.1 2019 02 22 16 08 34

While @itsage screenshots show "RX Vega10", mine shows "RX Vega12", is there a reason for the discrepancy?

Edit: just noticed it shows only 20CU, instead of 60CU, in the luxmark rendering test.

I injected the PCI ID into the info.plist in AMDRadeonX5000.kext.

Info.plist 2019 02 22 16 21 54

And repaired permissions afterwhich.

Edit2:Okay silly me I injected the PCI ID into the Vega 12 identifiers instead of the Vega 10 identifiers. Once I added the PCI ID into the Vega 10 identifiers and removed it from the Vega 12 identifiers, everything works with 60CUs showing up.

@kelvin_tan In the kext there are two different areas, look out for the key "AMDVega10GraphicsAccelerator", I think that is the right place for it. You did the injection in section "AMDVega12GraphicsAccelerator", therefore it is listed as a Vega12 model.

@kelvin

Is it possible to check the clock speed? 

As I understood you are using the 
driver of the vega10.
Between vega 10 and 20 there are 
differences. 60 vs 64 cus.
 And the Radeon runs with
 higher spied. 
I could imagine your radeon 7
 runs with the stock clock 
Speed of a vega 64 in a imac 
pro, 1350 mhz  
But only have 60 cus.

Given my experience so far, I would say to someone with an older AMD card to NOT buy the Radeon VII yet for egpu usage.

MBP 2018 15" with Asrock Radeon VII vs reference Vega 56 flashed to Vega 64

Pros

  • 15% improvement in 3DMark Firestrike (~19000 to ~22000, BootCamp W10 with Bootcampdriver 19.2.2)
  • 20% improvement in Superposition 1080 Extreme (~4200 to ~5100, BootCamp W10 with Bootcampdriver 19.2.2)
  • 48% improvement in Luxmark Ball render (~27000 to ~40000)
  • 6% improvement in Geekbench 4 compute (~139000 to ~148000)
  • About 10fps improvements in frame rate @ 3440x1440 for most games, from 40ish to 50ish touching 60.

Cons

  • Mac OS X experiences freezes every now and then - had two system freezes so far and had to hard reset. Not too sure if it's OS or kext related.
  • Running beta OS.
  • For some reason any form of Wattman tuning in Windows 10 causes games to crash. Even a simple -20mV undervolt. Not sure if I got a lemon or driver related.
  • It's much louder than my Vega 56, and unfortunately I don't use headphones while gaming, so it's quite annoying.
  • FCPX render times for a 3min 4k project with effects no change. Did not try Davinci Resolve.

For 20% improvements in game fps, the trade-offs at this point in time are quite severe. Compute-wise most applications are still not taking advantage of the 48% improvements in computing power, and if you are, you definitely should not be running mission critical work with a beta OS and hacked in kext extensions.

Will try overclocking with my X1 Yoga gen 3, very curious as to why I can't do any undervolting while the Vega 56 undervolted beautifully. Hope it's not a lemon of a card.

@kelvin_tan yes I agree, it's not good for macOS because of drivers. I also experienced freezes and had to reboot (sometimes in able to skip reboots buy connecting the HDMI cable into the integrated gpu of my Mac Mini and just turn off the egpu).

Weird thing is that it works very nice for me in bootcamp. I'm using official drivers 19.2.2. I'm able to overclock and undervolt easily.

Yes, can confirm that. When powering off the Mac (from macOS or BootCamp) leaving the TB3 cable plugged in, the VII fans (and/or the fans of the enclosure) run @ full speed.

@juan_c_yunis @roedi78 hmm thanks! Tried updating the bios earlier but could not get it to work. Nvm will try with the mantiz Venus + ThinkPad. For now Mac is reverted back to 10.14.3 and Vega 56 + Razer core X.

I'm just thinking to myself, really how the tables have turned. It used to be Mac just works, but now I find windows machines much more flexible and easier to deal with.

@kelvin_tan , you just forget that there is no official support of Radeon VII in macOS, so when 10.14.4 is finally released (march?!) I hope everything will run smoother.

@roedi78 Here's hoping to that! I remembered going through first half of High Sierra with drivers for Vega but non-functioning sleep, crashes, etc. I hope they get it correct with 10.14.4.

And reading up online people have all sorts of issues with USB hubs connected to their macs (of which I am one). I think proceed with caution is the operative word nowadays with Mac.

@kelvin_tan yeah even with externa drives i have had experience some freezes that only stop when i unplug the drive, i'm thinking of getting the CalDigit TS3+ TB3 dock, so I only use 2 ports of my Mac Mini (currently i'm using all of them lol).

I also use the CalDigit TS3+ TB3 dock next to the Sonnet Breakaway 650, so two TB3 ports of MBP are used. No issues so far.
Devices connected to the dock: USB-C audio interface, 2x Xbox One Wireless controller (via USB2.0), SSD USB-C, Ethernet, USB3.0-Stick (for automate-eGPU EFI).

@roedi78 just to confirm, you plugged the caldigit on the other side tb3 port? I have the ts3+ but have not used it - was hoping I can save a power plug and just use a normal USB hub.

If I were to plug it into the tb3 port on the same side as the egpu, I'm assuming I'll get half the bandwidth for the egpu?

@kelvin_tan @roedi78 damm, so envious lol. I would have to get it then. And yes you are supposed to leave the port next to the eGPU alone, so in my Mac Mini, i have the eGPU on port 1 and then 1 usb 3.1 Gen 2 RAID 0 enclosure in port 3, plus another external drive in port 4.

@roedi78 just to confirm, you plugged the caldigit on the other side tb3 port? I have the ts3+ but have not used it - was hoping I can save a power plug and just use a normal USB hub.

If I were to plug it into the tb3 port on the same side as the egpu, I'm assuming I'll get half the bandwidth for the egpu?

@kelvin_tan Yes, I connected both devices (Dock + Sonnet) on the right T3-ports on my MBP, because I had do disable left TB3 ports to overcome Error 12.
In detail also disabled some other components that I don't use in Bootcamp: CalDigit CardReader, FacetimeCam. Together with left TB3-ports (#1905) I disabled dGPU (#1901), because I don't need it and the system becomes more stable if I do so.
Regarding bandwidth: I do not "feel" any effect on that, my benchmarks are pretty much the same to others here.

Edit: The only thing I worried about was wether it is a (technical) problem to connect two power supplies at the same time to the MBP. But I read that this is allowed, the MBP loads only via one of the PD systems.

AMD seems to be offering a new BIOS V106 for the RadeonVII on their site:  https://www.amd.com/en/support/radeonvii-vbios-eula

I'm rather new to this stuff, but you all can certainly help me: What's the difference between the 2 versions they are offering (VII BIOS V106 x64 and x86)?

If you have x64 Windows 10 running you’d want the x64 version of the VII BIOS V106.

I hoped that would be the answer, thank you.

but does that mean that 86 refers to what?
