Blackmagic's first Apple-oriented external GPU was helpful for pros who needed more graphics power for their MacBooks, but it was a tough sell when you were paying $700 for strictly middling Radeon Pro 580 graphics. However, the company is back a few months later with a somewhat better value. Its newly launched Blackmagic eGPU Pro melds the familiar Thunderbolt 3 enclosure with much faster Radeon RX Vega 56 graphics. It's nearly twice as fast as the original, the company said, and promises up to a 22X performance boost over the 13-inch MacBook Pro's Intel-based video. That's a huge deal for GPU-aware creative apps, and might even make it a viable choice for more intensive games (what intensive games exist on the platform, anyway).
