MP 7,1 GPU rendering on the new Mac Pro. News, updates, chat.

Jules mentioned that he knows the release date, but is waiting for clearance before he can speak. That doesn’t necessarily mean tomorrow is the day.
Shouldn't we open a new thread titled "GPU rendering on the new Mac Pro ARM MAC PRO (?). News, updates, chat."
Based on my experience, I bet that any more effort by 3rd party developers on the original topic is pretty much futile.

I took your advice and looked forward, but now am disappointed, and blame you. Affinity photo mentioned in the Metal for Pro Apps talk but no Redshift or Octane.
Why? Metal works on both Apple Silicon and AMD GPUs. The CPU architecture isn't really relevant.
But Apple Silicon includes the Apple GPU and is Metal substantively caught up on that GPU architecture.
Metal isn't as a robust solution for OpenCL and yet that is the path. It is a convenient peg for Apple to pound that has the best fit from the Apple GPU. Not sure if this rendering GPU compute problems renders with has similar priority mismatches . [ If Apple had to choose between Metal tweak to help "prove" their iGPU was good enough in their inital Mac systems versus getting some third party app working better with AMD GPUs is Apple really going to put the latter on a higher priority burner than the former. Probably not. Similar if apple has real time ray tracing updates coming for their GPU and AMD has some for theirs ... which one gets priority resource assignments ? ]
The deeper Apple gets into the GPU business just how skewed is Metal going to get ? Apple does a piss poor effort of setting expectations there. And this year long fumble with Octane only cements that further.
Apple now has a beta Metal Ray tracing API for macOS 11 ....

Not really? I think Apple's drivers might be more mature than something like the Navi drivers, but for features they're pretty close. And if Apple supports AMD MPX modules or eGPUs on ARM hardware, then what does it matter anyway? Applications will still need to maintain support for rendering without the A series extensions like tile based rendering or unified address space. Apple at WWDC advised developers not to rely on the presence A series GPU capabilities, so even if they haven't said AMD GPUs will be available on ARM Macs, they've left that door wide open.
The A series has some niceties, and the A series is fast, but it's nothing that's going to help with what Otoy is probably dealing with. There's no rich library of pro app Metal features on the A series that hasn't been available on the Mac.
Octane news from OTOY's forum "RC1 just went live yesterday in closed beta. If testing goes well (so far it is) through the weekend, we should be able to announce a date for our first official public preview next week. Thank you all for your patience!"
Redshift devs are operating "it will be ready when it's ready" policy, it's frustrating how slow they have been since the Maxon buyout - still no toon shader, randomwalk, no news on Redshift RT.

That’s such a joke — “we should be able to announce a date”, which means that this will only be an announcement, not a release. I won’t be surprised if their so called “release date” is in September or later.
And also not surprised if it includes macOS 11 as system requirement. Public beta next weeks means could easily coincide with public beta macOS 11 ( or limiting beta to those who have a developer beta macOS 11 ) .
If they ended up having to wait for macOS 11 to get it 'done' then that ended up being a very substantive part of the delay. ( as opposed to some 10.15.x , 'third set of digits ' version. )

FP64 ? Metal has 'blind spots' that are driven by Apple primary deployment of their GPU on iPhones.
Well, after another week of 'coming soon', OTOY has at least announced that they have a release date – they just didn't say what it was. Hopefully next week we'll get some more in-depth details – though I doubt the actual release is still not quite here yet.
I'm guessing public beta first and production ready version not until macOS 11 as @deconstruct60 suggested.
Can't believe I'm saying this, but I'll probably keep my cheesegrater in active service until the ARM transition is complete and Redshift and Octane have matured a bit on Metal.
This is definitely the greyest my beard has ever been.
I'd be surprised if it needed macOS 11, but after this tedious year-long-and-counting wait, anything is possible.
Jules was really throwing the video of Octane X on iPhone out there on the Facebook Octane group(s) for awhile. Seems he just might be really interested in Octane X on Apple Silicon. I can only imagine what might come of Octane X running on a HPC APU (32 P cores / 16 E cores / 64 GPU cores / 32GB HBM2e UMA / 420W / entry-level workstation / Mac Pro Cube) from Apple Silicon. Add in the fact (from what I have read here & there on the interwebs, at least) that the dude in charge of Maxon is a huge Machead, as long as Apple can provide some real 3d workstations with their Apple Silicon, viable 3D might become a real thing on the Mac (again?).
Apple Silicon Mac (Big Chungus) Pro...?
64 P cores / 24 E cores / 80 GPU cores / 48GB HBM2e UMA / 600W

It’s been announced: Octane X is being released on July 17 according to an OTOY tweet
Anyone want to tell us their setup? I have a Mac Pro with an RX580X module, an old RX580 that drives the monitor, and an RX5700XT which was supposed to drive the monitor but isn’t (yet) as stable as the 580.

My BF has a Mac Pro with 96GB and a Radeon Pro Vega II Duo and an eGPU driving his monitor.
I would fully expect them to be slower. But AMD has Big Navi in the pipeline, so while I think current comparisons won't be great, things should be different in the future.
Certain I've seen something from OTOY saying the Vega II Duo is the fastest single card they've benched (which you'd hope so given it's essentially two cards) I'm hoping that given the price it's equal to a Titan.
But even then, can you fit 4x Vega II Duo in the new pro? From my limited research it seems the most you can fit is two, and a third double wide card. Someone correct me if I'm wrong. If you can fit four of them that'd be excellent news.
The Apple website clearly shows & explains that the 2019 Mac Pro can support up to two of the Radeon Pro Vega II Duo MPX Modules. Which means it will have four Radeon VII GPU chips in the system, with 128GB of HBM2; eager to see what kind of OctaneBench scores that will give...!?!
After all, there are only two MPX slots in the Mac Pro...
