fwiw, the VII has a lower temp under load than your 1080ti : https://www.guru3d.com/articles-pages/amd-radeon-vii-16-gb-review,7.html

That said, I had a R9 290x before and that puts both to shame, never had an issue with temperatures in the case.

Lower temperature because more heat is extracted from the chip. Not because it release less heat to the PCIe compartment.

It’s the power draw affect total heat generation. GPU temperature just measuring how good the onboard cooling system is.

In this universe, where we suddenly got things like the ability to use NVME and Vega GPU support, I supposed anything can happen :)
There’s hope for that, but I think those were meant to keep people from switching to windows already and wait a little more until they have the second coming of the trashcan ready.

It would be a nice goodwill gesture to make it compatible with the 5,1. I know it won’t happen.

Unless it has different form factor. I believe the theory we discussed that Apple was going to offer Apple proprietary GPU and SSD upgrades for nMP but they realized they couldn't when AMD Fiji was power hungry. The nMP design, PSU and thermals made them get stuck in a corner and the upgrades were abandoned. Polaris also came late was not high end enough. It's a good theory I think because it would be great if Apple offered optimal component upgrades every year for the Mac Pro. I think we'll get 700-800 watt PSU next time.

The 7,1 GPUs will work in the 5,1 if they're a standard PCIe card, but I don't think they'll support the 5,1 boot screen and you'll need to power them like any other Vega GPU. The benefits would be best compatibility and a specific framebuffer. Don't expect to be able to flash a PC Radeon VII with the Mac rom though because they have a different device ID.

That’s an excellent reason not to repeat the same mistake this time, sticking with standard form factor.

The theory you mentioned makes perfect sense.

Let's be real, RX 580 support came directly from eGPU, Apple inserted NVMe support to every supported Mac (even for Macs that don't have connectors capable of installing NVMe M.2 blades, like classic mid-2012 MacBook Pro), VEGA support came from iMac Pro/MP7,1.

If Apple really support hardware decoding/encoding and Safari can play Netflix, then I start to believe that someone there really care for MP5,1.

The 5GT/s is a mac pro specific thing, isn’t it.

Anyway, I think it’s only life support until the new mac pro arrives and then it’s goodbye.

Yes, it is.

Obviously I was playing the cynical part, Apple spent a lot of engineering resources getting everything right with, at least, 9 firmware updates in less than two years.

The sad thing is that if MP6,1 was a success and MP7,1 was released in the usual timeframe, Apple would not spent a dime with MP5,1 support nowadays.

Why the heck did Apple hobble the 5,1 with 2.5 GT/sec in the first place? They were afraid all their PCIe GPUs would burn out ahead of schedule?
