![]() ![]() From forum members' and my experience, Port #5 and #6 are more eGPU-friendly than others. There are 6 Thunderbolt 2 ports in the back that pair up with 3 Thunderbolt buses internally. The 2013 Mac Pro differs from other Macs in that it has no integrated GPU. Goalque's automate-eGPU script makes installing external graphics cards for Mac a much less frustrating process. FreeSync is an AMD technology available on certain monitors that synchronizes the frame rate between the monitor and compatible AMD graphics cards. In macOS, I ran the RX 580 eGPU on a Late 2013 Mac Pro. The host in Windows was a Razer Blade Stealth. The external display is an LG Ultrawide 34UM68P with FreeSync. For this RX 580 external GPU review, I'm using the Sonnet Breakaway Box Thunderbolt 3 enclosure. The prerequisites are R9 and RX graphics cards paired with a high-compatibility eGPU enclosure. The ultimate goal for an external graphics card is to function similar to how an external hard drive does.ĪMD XConnect gets us very close to this goal. AMD and Nvidia have developed software solutions, XConnect and Optimus respectively, to handle graphics card switching in the Windows environment. AMD XConnect team in particular is very active in promoting external GPU. This will speed up adoption rate due to lower certification and manufacturing costs. It plans to unleash this technology under a nonexclusive, royalty-free license. Intel has been making a big push for Thunderbolt 3. In Windows, eGPU implementation is easier and works better. We hope there will be collaboration and involvement from other developers as eGPU gets more recognition. In macOS, the few active eGPU developers are goalque, rastafabi on eGPU.io and netkas on his forum. ![]() I make this distinction because eGPU in general and eGPU for macOS in specific is still in its infancy. My review of the RX 580 is strictly based on its use as an external GPU. You've most likely read reviews of the RX 580 from popular outlets. Thunderbolt is the natural conduit for this task. The solution was to connect Macs to these newer and more powerful GPUs via an external PCIe enclosure. The problem is there are very few Macs with full-length PCIe slots. While these drivers were never intended for the RX 480, the genius minds ( Pike's, netkas, Fl0r!an, okras, and others) in the Mac community figured out a way to make it work. The Polaris 10 GPUs arrived at the right time as Apple released macOS 10.12 Sierra with drivers for Polaris 11 graphics cards. The three reference RX 480 graphics cards I own are currently enclosed in a 2010 Mac Pro tower. They serve as beta testers for newer versions of macOS so that I can provide up-to-date information on my RX 480/580 installation how-to for Mac.īeing Mac users, we don't always have the luxury of choosing any graphics card we want. It's the graphics card that lured me into higher GPU performance for the Mac platform and my eventual involvement with the eGPU community. I've been testing a Gigabyte Aorus RX 580 XTR 8GB factory overclocked to 1439 MHz.ĭisclosure: I'm very fond of AMD Radeon RX 480. The Radeon RX 580 brought performance improvements at the same price point as the outgoing RX 480. As a matter of fact, the two cards share the same PCI ID 67DF. It's a refined version of the highly successful mid-range graphics card from last summer, the RX 480. List of supported graphics and general-purpose computing APIs, including their specific versions.AMD launched its Radeon RX 500 series GPUs a month ago with the RX 580 leading the charge. OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). Types and number of video connectors present on the reviewed GPUs. Integrated GPUs have no dedicated VRAM and use a shared part of system RAM. Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). Useful when choosing a future computer configuration or upgrading an existing one. Information on compatibility with other computer components. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. ![]()
