I'd rather not, as it's at the right price point and the newer architecture is nice to have for video encoding/decoding and DSC running my dual XDR's but ... perhaps with this setup I should be running the 32GB Vega II anyhow? Ugh ... thousands more on this thing *face palm*. Absolutely awesome system overall though.
Honestly, I can't imagine the Vega II is terribly useful unless you already know you need it. And even then, if you weren't using the XDRs, then I'd probably just grab a WX 8200 instead, if the Navi cards are out of the picture.
I can't imagine Apple would just leave the system in this state though.
No, but it's more a question of "how long".

BTW, I hit the perf problems immediately after booting up the machine with the W5700X installed. I don't even bother with the OpenGL/OpenCL tests. When I'm working with the GPU in code, I'm on Metal, and the apps I use have pretty much all migrated as well.
MetalBench was showing an average of 600Mrays/sec. To give you an idea, an iMac with a M295X in it gets 1100Mrays/sec. Yeesh.
Affinity Photo felt a lot like using it on the Mac Mini's iGPU. Usable, but chugs on larger projects and can't keep up with my monitor's high refresh rate (although that's a minor issue).

So far, some differences I noticed on Beta 3:
GB5: Reliably shows ~70000 as the benchmark after multiple runs.
MetalBench: ~4000Mrays/sec on average after running it for many minutes while typing up this post.
MacPro Fans: In the crippled state, the card never gets hot enough to spin up the Mac Pro fans above their base speed. But in this case, MetalBench was able to get the fans to spin up after a couple minutes. About as loud as the Mac Mini, but with a lower tone.
Affinity Photo Large Projects: These are my go-to tests to see how Affinity Photo is impacted by the GPU. Much improved and makes my Vega 56 eGPU setup feel slow.
Good.
This is what it's supposed to be doing. Although there are some specific cases where the 12-core CPU can actually hold its own against the W5700X due to PCIe latency for compute. Interesting.
Although the thing that shows how even this is a bit overkill is that my smaller Affinity Photo projects that don't use a lot of masking can easily keep up with a 120Hz refresh rate that my monitor supports when positioning layers/etc without breaking a sweat on the canvas. Even my big projects with masking get up in the 80+Hz range.
Good.
Keep in mind this is preliminary, I need to keep an eye on it for a bit. But at least so far this is more along the lines of what I paid for.
