2011 15" MacBook Pro (HD6750M) [2nd,4C,Q] + RX 580 @ 10Gbps-TB1>TB3 (Sonnet Breakaway 350) + macOS 10.13.2 [Azure]
Early 2011 MacBook Pro 15"
Core i7-2720QM quad core 2.2GHz (Sandy Bridge), Thunderbolt 1
16GB RAM 1600MHz DDR3
Intel HD Graphics 300 512MB, Radeon HD 6750M 1GB
24" Samsung 2493HM 1920x1200
Gigabyte AORUS Radeon RX 580 8GB
Apple TB2 cable (50cm)
Apple TB3 to TB2 adapter
Installed the Radeon in the Sonnet enclosure, made very simple by the Sonnet enclosure's 3 thumbscrews to remove the case.
Connected the enclosure to the MBP via the TB cable & TB2-3 adapter, powered on the enclosure, received the prompt from macOS to log out.
Logged out, image displayed on the external monitor immediately at the login screen.
Logged in, verified details in System Information, worked beautifully!
Unigine benchmarks using strict presets only, no custom settings.
Put together pretty much to upgrade my WoW experience, at existing settings (3), instantly pulled 277fps. Very happy! Am able to play at max detail (10) with the 3 distance sliders (env dist,clutter,objects) @ 7 and maintain over 60fps.
I find this config rather interesting, as I believe this particular Mac was the first to implement Thunderbolt, and it's now 7 years old, and still very quick and usable! Woot!
