Not according to this benchmark, the 5700 XT thrashes the Radeon VII compute score.

And quickly abandoned the other benchmarks when show the VII is faster.

USB-C but NOT Thunderbolt 3 right? Means no Apple 6K support or am I wrong?

No 6K support. The 6K display needs to be feed two DP 1.4 streams I think (as much of two 1.4's that Thunderbolt can carry.. which is just enough). The USB-C socket if just using Alt-mode DisplayPort is only doing at bet one DP 1.4 stream. ( if not capped at DP v1.2 ). The card is capable of driving 6 displays and there are six outputs, so it is unlikely there are two being feed out that one port. Being labeled simply USB-C just adds to that.

It is likely there is a USB 2.0 subchannel there too ( similar to the initial 4K USB-C only LG Ultrafine display. Good for keyboard and mouse on display.)

Adding a USB-C Altmode DisplayPort socket now only lays the ground work for DisplayPort v2.0 in later years. Once that rolls out in a couple of years USB-C ports won't be rare anymore at all.

 

[deconstruct60]

If you're JUST talking about the Pro Display XDR, my understanding is the Pro Display XDR supports TB3 as "video" input only. All USB-C are for hub-style functionality.

Closer would be is that the XDR has one , and only one, input port. That port is TBv3. The other USB C ports are not input ports. They are output and "plain jane" USB ( no alternative modes ).

It is like every other Apple monitor in the last decade or more... there is only one input. ( and typically no control buttons either. ).

 

[deconstruct60]

Worth noting this GPU includes a USB-C port, which has been a gripe for some on this forum recently. This MIGHT be one of the first standard GPUs to offer this natively.
....

While there was some earlier buzz there was build in support for VitrualLink alternative mode in the 5700 ( that wasn't in the reference boards. https://www.pcgamesn.com/amd/navi-virtuallink-support-rx-5700-xt )

There is no direct claim feature support support here. VirtualLink shovels the USB 3.0 connection onto the USB 2.0 bus ( which makes it more than just a simple "AlternativeMode". and probably contributes to why I think it is in the "proposed" status and not really a standard. ). I think USB4 should obviate the need for VirtualLink ( without hijacking the USB 2.0 bus. ).

AMD may have started the work on that mode but just left it at a plain DP alt mode and supplying 'minimal' 15W power on the connector. ( but not quite hijacking the USB 2.0 bus and default USB 3.0 data stream if don't invoke DP alt mode. ). So a 'free' Type-C port if host system doesn't have one. macOS wise as long as there is a USB driver for it should just work.

I'm interested to see if Apple will release a W5700 MPX GPU for the new Mac Pro.

 

[MisterAndrew]

The new Radeon Pro W5700 is indeed supported under macOS Catalina. It appears there are two variants because it's listed as having both 0x7310 and 0x7312 device IDs in the Windows 10 driver. Both of those are contained in the Catalina driver.

 

[MisterAndrew]

I figured out 10.15.1 build 19B2106 for the 16" MacBook Pro contains the Navi drivers for Navi 14 GPUs such as RX 5500 & 5500 XT, and of course the Pro 5300M and 5500M. So if you wanted to install an RX 5500 or 5500 XT into a cMP you could try transferring those drivers over from that build or try installing that build on your machine, or just wait for 10.15.2 which should contain those drivers in the standard build.

Apple just pushed an update for the native MP5,1 BootCamp that allows Restart in MacOS to function properly again. No more blind PRAM reset required for dual booting (with Windows) when using upgraded GPU's.

Any news about higher end GPUs than the 5500 or 57000 XT?

Also, when is 10.15.2 planned for?

 

[MisterAndrew]

I don't see any news about higher end Navi GPUs. RX 5500 XT is apparently launching next week, and RX 5600 XT next month. Radeon VII has seen a price reduction. Hard to say when 10.15.2 will be released. Possibly tomorrow.

 

[bsbeamer]

Seems they’re having a hard enough time keeping the 5700 XT’s in stock right now, so would guess they’re not exactly rushing to release higher end models unless it’s somehow heavily compute based (like Vega 64) or 16GB VRAM offering.

 

[koyoot]

Does anyone know whether Navi 12 is in the drivers?

 

[thisisnotmyname]

Does anyone know whether Navi 12 is in the drivers?

There's a semi-custom Navi 12 variant in the drivers with the code name Goovaerts.

Do you have a link for this Bootcamp release ?

Thanks in advance

You are correct that Apple recently released a new BootCamp package, November 19 Product-ID 041-93123, but it's for MacBook Pro 16".



The MP5,1 BootCamp, Product-ID 041-84868, was reissued October 22 and it's not a new package. Apple didn't correct anything with this re-issue since the package was just re-signed with the new certificates, same 1.0.1.1293150744 version.

 

[tsialex]

Direct links:

MP5,1 BootCamp re-issued 1.0.1.1293150744: 041-84868.
iMacPro1,1 BootCamp re-issued: 041-91731.

Any news about higher end GPUs than the 5500 or 57000 XT?

only rumors so far I believe. the GPU(s) that AMD described as "nVidia killer(s)" might get a glimpse of these at CES 2020. AMD roadmap does suggest we would see them at some point in 2020

 

[MisterAndrew]

There's an MPX Radeon Pro W5700X coming for the Mac Pro.

 

[MisterAndrew]

Apple officially supports the installation of 3rd party GPUs in the new Mac Pro.

https://support.apple.com/en-us/HT210408

They even have instructions on how to use an off-the-shelf AMD GPU with Windows.

Anyone know how the W5700X compares to RX 5700 XT 8GB, at least on paper? Been testing an RX 5700 XT in an eGPU, but about 33% worse METAL performance in Catalina than an RX580 8GB in Mojave with MP5,1. Hoping drivers may eventually improve METAL performance.

How you measure this performance difference?

 

[bsbeamer]

A lot with real world METAL acceleration tests in specific applications, but GB5 is easiest direct compare with scores (but REALLY don't like the test).

MBP16,1 26963 is best METAL benchmark with 5500M 8GB in 10.15.2 (built in dGPU)

MBP16,1 33742 is absolute best METAL benchmark with Sapphire Pulse RX 5700 XT 8GB via eGPU in 10.15.2 been able to achieve. Most other results are 32XXX range or less.

MP5,1 39004 for METAL benchmark with Sapphire Pulse RX580 8GB in 10.14.6

Even GB5 is showing ~15% lower METAL benchmark for RX 5700 XT 8GB, testing with the latest 10.15.2 driver.

An RX 5700 XT (with 40 compute units) should really be doing better than an RX580 (with 36 compute units). Truly believe it's a driver issue on macOS. Same results are not reported in Windows by other users.

Thanks, because I can’t quite find a good Metal computer benchmark, that’s why I wonder how you measure it.

If that’s from real workflow, obviously that’s meaningful to you.

For GB5, I really doubt it’s accuracy for GPU Metal performance measurement.

I do wish there was a better benchmark app for measuring METAL. Would make testing and comparison a lot easier. Hardware acceleration for video encode for those that can support is a good test, but CPU plays too much of an additional factor if machines themselves are not close to equivalent spec.

Truly do not trust GB5 and usually end up running 5-10 times and taking an average.

RX 5500 XT: bad pricing

I don’t think so. Starts at $169. It has better graphics performance than RX 580 while consuming less power. However, it lags behind on compute like other Navi GPUs.
