Win10 1803+ provides manual graphics switching per app/game through Graphics Settings. In a Mac that has an AMD discrete graphics card and no functional iGPU, you would need Windor newer. AMD XConnect/Nvidia Optimus provides internal display loopback acceleration through the Intel iGPU with a Radeon/GeForce eGPU. In order for automatic graphics switching to work, the crucial prerequisite is the Intel integrated graphics card.If you want to start up using the default operating system now, click Restart.2018 15″ Macbook Pro + Radeon VII eGPU – Windows Graphics SettingsDavid Haywood has turned his attention to bootlegs of games including Final Lap 3. Select the startup disk that has the default operating system you want to use. If a User Account Control dialog appears, click Yes.
![]() Bootleg Windows Mac That HasThey account for 16 total PCIe lanes directly off the CPU. The x4 PCI Express Controller connects to the right-side USB-C/Thunderbolt 3 ports (uses 4 PCIe lanes). The x8 PCI Express Controller connects to the left-side USB-C/Thunderbolt 3 ports (uses 4 PCIe lanes). The x16 PCI Express Controller connects to the Radeon Pro dGPU (uses 8 PCIe lanes). For example we used HWiNFO64 to check the arrangement of PCIe controllers and lane allocation on a Late 2016 15″ MacBook Pro (same as 2017 to 2019 model). Therefore the right-side Thunderbolt 3 ports on these newer 13″ MacBook Pros have full x4 PCIe bandwidth. 2018 & 2019 13″ models use Intel 8th generation quad-core U-processors that provides more PCIe lanes. This is due to the x2 PCI Express Root Port #9 – 9D18 to which these ports attach. Apple Thunderbolt 3 support article states that the right-side Thunderbolt 3 ports on the 2016 & 2017 13″ Touch Bar MacBook Pro have lower bandwidth than the left-side ports. All PCIe lanes are routed through the platform controller hub (PCH). Supported MacsMacBook Air (13-inch, T2 Chip, Early 2020)MacBook Pro (16-inch, T2 Chip, Late 2019) *MacBook Pro (15-inch, T2 Chip, Mid 2019) *MacBook Air (13-inch, T2 Chip, Late 2018)MacBook Pro (15-inch, T2 Chip, Mid 2018) *IMac Pro (5K, 27-inch, T2 Chip, Late 2017) ** Indicates a Mac with discrete graphics card as standard equipmentPrior to the 2020 13″ MacBook Pros which use Intel Ice Lake processors (on-die Titan Ridge Thunderbolt 3 controller) all ULV-processor Macs have no direct Thunderbolt 3 to CPU connection. Similar to the TB3 15″ MacBook Pro, the x16 PCI Express Controller is reserved for the optional 10Gb Ethernet card (uses 8 PCIe lanes), the x8 PCI Express Controller connects to the two USB-C/Thunderbolt 3 ports closest to Ethernet port (uses 4 PCIe lanes), and the x4 PCI Express Controller connects to the two USB-C/Thunderbolt 3 ports closest to the HDMI port (uses 4 PCIe lanes). On top of that is a pair of Thunderbolt 3 controllers to power four Thunderbolt 3 ports. In a way the Mac mini combines the most desirable elements of a powerful quad-core+ processor with iGPU-only graphics. Also more encouraging is the 65W processor and direct Thunderbolt 3 to CPU connection. This is great news for eGPU users, especially in Boot Camp mode. We captured the PCIe arrangement of the Thunderbolt 3 15″ MacBook Pro (shown on the left) and Thunderbolt 3 Touch Bar 13″ MacBook Pro (shown on the right) in HWiNFO64 and labeled them for reference.Overview of PCIe Lane Arrangement in Thunderbolt 3 MacBook ProThe 2018/2020 Mac mini is one of the very few desktop Macs without a discrete graphics card. ![]() The answer is a sad joke that long-time Mac users understand all too well get AMD graphics cards for macOS and Nvidia graphics cards for Windows. AMD eGPU vs Nvidia eGPUWhat’s the best eGPU for Boot Camp is a question we’ve seen a lot. One positive news is the full bandwidth four PCIe lanes directly attached to CPU for Thunderbolt 3 connection. For the red team, get ready to go on an adventure called, error 12. More than likely it will work without much trouble. If you decide to go with the green team, stop reading any further and go hot-plug the eGPU to your Mac. Should i switch to mac from windows for graphic designersThrough many different user build guides, we have gathered not only setup procedures but also pre-compiled DSDT override files for those who need to patch the firmware of Late 2016 MacBook Pros.Mac computers with only two Thunderbolt 3 ports would likely be able to negotiate enough resources for eGPU automagically. Large Memory allocation helps Windows handle a PCIe component such as an external graphics card without error 12. Other than the Late 2016 Thunderbolt 3 Macs, 2017 and newer models have “Large Memory” allocation in the firmware. Radeon ProThe name of the game is to allocate enough resources for the external graphics card to function in Windows 10 while not severely crippling other functionalities of the laptop. Currently the recommended version is WindOS Build 18362.295. These are the AMD Radeon cards with native macOS eGPU support and can function in Boot Camp. The majority of reported successes are with Nvidia graphics cards. It’s best to confirm whether the Mac firmware has “Large Memory” in Device Manager > View > Devices by resources to determine the next steps.Only a handful of Macs can work with an eGPU via hot-plug in Windows Boot Camp. Macs with four Thunderbolt 3 ports are slightly harder for eGPU implementation due to an extra Thunderbolt 3 controller and two more Thunderbolt 3 ports. If you’re familiar with using an external graphics card in Windows 10 via Boot Camp, proceed to the summarized setup procedure. Here are the recommended steps to set up an external GPU with a Thunderbolt 3 Mac and the reasons behind them. The most reliable method is cold-plug. We have also learnt timed hot-plug can work with both Nvidia and AMD eGPUs. Also keep in mind Security Updates may break eGPU compatibility. If you experience issues, go with Win10 1809. With the exception of a few models such as 2017 13″ MacBook Pro (boot loop when paired with Radeon eGPU), most Macs work well with this latest Windows version. Mac computers greatly benefit from these changes in Win10 1903. Microsoft improved hot-plug detection and handling of Thunderbolt 3 devices in this version. If your MacBook Pro has a limited amount of storage, partition the Boot Camp volume with 50GB for Windows installation and save the rest for the macOS partition. We don’t recommend having the Windows volume on an external drive because it would complicate the eGPU setup process and may cause unforeseeable maintenance issues. It’s best to disable automatic updates once you get a working configuration.There are setup guides to install Windows on an external hard drive so that the internal PCIe flash storage can be preserved solely for macOS partition. ![]()
