2018 13" MacBook Air [8th,2C,Y] + RX 580 @ 32Gbps-TB3 (Gigabyte Gaming Box) + macOS 10.14 [JediTreasley]
In my case, The Vega 64 new (wanted warranty) was cheaper than a 56 new (lol) with that AMD 3-game bundle. But yes, power is an issue with the GPU if not undervolted in macOS. At one point the GPU was consuming 563W - yes, 563 in macOS - too much for an 80+ Corsair SF 600. In Windows with the available undervolting mechanisms I am overclocked plus at peak 210W.
@mac_editor is this a normal case? that's absolutely crazy in terms of power consumption. That's as much as the old dual 390 cards were doing. Maybe I should look at a 56 or at another 580? I just feel the 580 is weak, especially since I'll be using it with the internal MBA screen. Wonder if Apple will make Nvidia official anytime soon.
IMO an RX480 has better power consumption than a 580 (latter guzzled more for measly performance improvements, having had both for a time). I am currently selling the 480 on this forum if interested. Undervolt the 480, and at 80W one would have a fantastic performer, though this GPU doesn't need it. Though I agree overall a mid-range card, it's good for the price.
Otherwise a good balance for you would be Vega 56.
Someone is willing to give me $150 plus his liquid cooled r9 390x for my new 1070 ti, not entirely sure how good of a deal this is or if the R9 390x will be plug and play like the Auros 580 box I had was.
@jeditreasley It should work once web drivers are out.
Did anybody upgrade to macOS 10.14.1? Have you noticed any differences? I somehow have a feeling that my mbp 13 2018 with the rx580 gaming box is not performing at its best and not much better than my mbp13 2015 did.
Can anyone tell me know many PCI lanes does the new Macbook Air provide?
@mansle89 It has an x4 PCIe connection to the Thunderbolt 3 ports. Here's my build with the RX 580 eGPU [Zotac AMP Box Mini]. The weak processor and ineffective cooling system is more of a concern. When I paired it to the GTX 1080 Ti eGPU [ASUS Station Pro], the system bottle-necked the eGPU badly.
