Performance Results: 1920 x 1080
While larger and faster graphics cards technically fit in Sapphire’s GearBox, the Thunderbolt 3 interface’s four-lane PCIe 3.0 link kept our ambitions humble. A Radeon RX 590 is ample for smooth gaming at 1920 x 1080, so that’s where we ran our benchmarks.
And it’s a good thing, too. In certain cases, the external graphics box took a pretty serious performance hit. In fact, the slow-down was severe enough to cut the Radeon RX 590’s average frame rate down to somewhere between a GeForce GTX 1050 Ti 4GB and a GeForce GTX 1650 in many workloads.
That’s going to be a hard pill to swallow for gamers eyeing specific GPUs with an expectation of performance gleaned from benchmarks run on desktop platforms.
