Hey all,

Need some advice. I'll make this short. I have the 16 in MacBook Pro and a Pro XDR display. I want to game at 6K. What eGPU should I buy and what graphics card? There is no cap on the budget. 

Thanks,

AK

Best GPU you already have: MacBook Pro 8GB 5500M

Best eGPU: Blackmagic eGPU Pro with Vega 56

 

 

2018 Mac Mini i5 / 6-core 3.0-4.1 Ghz / 32GB / 256GB / Intel UHD 630 / PowerColor Gaming Station / PowerColor dual-fan RX5700 XT / Mac OS 10.15.3 Catalina / LG 27" 4K display

For Windows gaming, the most powerful GPU currently is the Nvidia RTX 2080 Ti. It has a USB-C port so it should support the USB features of the display. Might be interesting to try to manually install the Boot Camp drivers for the display (presets and brightness control?).

For Mac gaming, 5700XT but those don't have a USB-C port so you'll be missing the USB features of the display.

When using an eGPU, I would not try loop back mode (where the display is connected directly to the MBP instead of the eGPU) because 6K is a lot of data and will slow FPS greatly if those pixels need to be moved from the eGPU to the dGPU. Instead the display should be connected to the eGPU.

The W5700 has a USB-C port but this GPU is not as powerful as the 5700XT.

The Blackmagic eGPU Pro supports a Thunderbolt connection to the display so all the features of the display will work but the Blackmagic eGPU is not supported well in Windows? Or might require a little more work than other eGPUs. Blackmagic eGPU Pro only has a Vega 56.

You'll want to compare benchmarks of the GPUs and decide if you want to connect via Thunderbolt (Blackmagic eGPU), USB-C (RTX or W5700), or DisplayPort (any other GPU).

Thunderbolt 3 via Thunderbolt 3 add-in card (GC-ALPINE RIDGE or GC-TITAN RIDGE) won't give you anything extra because neither will give 6K (the GC-TITAN RIDGE could, but the firmware doesn't allow it) and there's no software currently to get you the USB functions of the display (by enabling PCIe tunnelling).

Thanks guys for the suggestions. Seems like it will be quite hard to get to 6K, which I was expecting. Does AMD have anything coming out soon that is better than the Vega 56 and 5700 XT?

@akishore If budget is unlimited, I’d recommend getting 2x Vega II Duo MPX Modules. One minor issue is the eGPU enclosure for those two starts at $5,999. 😀 

Joking aside you can technically run the 2019 16-in MBP Target mode and connect it to the 2019 Mac Pro + Pro Display XDR with a single Thunderbolt 3 cable.

Not until the RX 5950 and RX 5800 are released. Waiting...waiting... 🙄

What's easier than eGPU + GPU?

I think the only issue is that only the W5700 has a USB-C port for full functionality. But any Navi card should allow 6K. In theory, the Huawei VR 2 Computer Connection Cable should allow 6K + USB. The quality or length or something limits it HBR2 speed (4K60) but with DSC, you only need HBR2 to get 6K. I think itsage had a problem where his cable stopped working (but that might be because he was using it to power a USB-C display?).

I wonder if the Wacom Link Plus can pass USB + HBR2 with DSC for 6K?

Or a Sunix UPD2018 in a Thunderbolt 3 expansion box?

@joevt That was a little over my head, but I'm trying to understand. So you're saying the W5700 Pro could handle the 6K? Also, what is DSC? And what eGPU enclosure do you suggest? And these expansion boxes are needed to go from DisplayPort to USB-C or something? Sorry if I sound like an idiot...pretty new to this stuff.

If you want ot game in 6K (slightly unrealistic expectation depending on game) you're best bet is to instal bootcamp and get an Nvidia card (2080ti).

2017 13" MacBook Pro Touch Bar
GTX1060 + AKiTiO Thunder3 + Win10
GTX1070 + Sonnet Breakaway Box + Win10
GTX1070 + Razer Core V1 + Win10
Vega 56 + Razer Core V1 + macOS + Win10
Vega 56 + Mantiz Venus + macOS + W10

6K at what frame rate? 5 fps or 120 fps? The first is achievable, the second maybe with the Titan series of nVidia

6K at 60 fps. That's the highest refresh rate for the Pro XDR display. Using the 5500M internal card, I get about 10 fps in Tomb Raider at 6K. If I can get it to at least 40 to 50, that would be playable.

Or swap to a Mac Pro with dual graphics. 🙂

Display Stream Compression (DSC). Part of DisplayPort 1.4 spec.

The Apple Pro Display XDR has many connection modes that it can support.
HBR2 4K 10bpc
HBR3 5K (8bpc) (I don't think I've seen this work yet).
dual HBR2 (Thunderbolt only) 5K 10 bpc
HBR2 with DSC 6K 12 bpc
dual HBR3 (Thunderbolt only) 6K 10 bpc

The connection can be made using USB-C with DisplayPort Alt Mode (except where noted) or with Thunderbolt.

The Nvidia RTX cards and the AMD Navi cards support DSC (5700, 5700XT, W5700XT, W5700) so they all should support 6K. The RTX cards and the W5700 have a USB-C port that you can use with a normal USB-C cable. The connection will include USB to support the USB features of the display (USB ports, brightness control, presets?).

If you use a normal DisplayPort output, then you'll loose the USB features of the display, unless you use a method to combine USB with the DisplayPort output. I haven't seen anyone try those methods yet.

I don’t believe you can achieve that frame rate neither with a 2080ti or a 5700xt (which I own) but as looks you are a billionaire I would check the nVidia Titan series as already said. Another problem is the graphic library: old ones (OpenGL and DiirectX) mainly rely on processor power while the recents (Metal on Apple, DirectX12 on Win and Vulkan on all platforms) mainly rely on the GPU. If Tomb Rider relies on old graphic libraries... maybe (MAYBE!!!) a Titan us useless.

Is there a website that tells you which games use which graphics library? I just heard the news that Nvidia will be releasing their new graphics cards soon? I think I'll just wait till there is something a little more powerful. I waited about 3 years to finally buy this Mac and display. I'm gonna make sure the graphics card can handle this display.
