[GUIDE] correcting the eGPU name in "About this Mac" using iHex
Depending on the graphics card used, the GPU name listed in About This Mac may be incorrect. For example, when using the RX 480, the GPU is listed as a R9 xxx.
Before modifying the GPU name
The following steps can be used to fix this, if desired. It is not an absolutely necessary step to get your GPU working, but it makes for a cleaner-looking installation.
Step 2: Open Finder → Go → Go to Folder.
Step 3: Paste the following in the Go to the folderbox: /System/Library/Extensions/AMD9500Controller.kext/Contents/MacOS
Step 4: Drag a copy of AMD9500Controller to the Desktop
Step 5: Open iHex and drag the AMD9500Controller from the Desktop to the iHex app.
Step 6: In the iHex menu bar click Edit → Find → Find to bring up the Find menu, or simply use ⌘+F.
Step 7: Select Text and in the Find box, type xxx in lower case. You will find R9 xxx. Replace that text with RX 480 by placing your cursor in front of the ‘9’ and typing an ‘X’ and then placing your cursor in front of the first x in ‘xxx’ and typing 480.
Step 8: In the iHex menu bar click File → Save, or use ⌘+S. Close out of iHex.
Step 9: Drag the AMD9500Controller back to the /System/Library/Extensions/AMD9500Controller.kext/Contents/MacOS location. A popup will appear asking you to Authenticate. Click the Authenticate button, and click the Replace button on the next popup that appears. Enter your User Name and Password and click OK to successfully replace the AMD9500Controller with the modified version.
Step 10: Launch the Kext Utility app, and enter your password once requested. The Kext Utility will repair permissions for extensions, and only take a minute or so. Once it’s finished, click the Quit button and restart your MacBook.
Step 11: Check → About This Mac to verify that the GPU name has been updated.

Hello, does it still work in High Sierra 10.13.1? I couldn't complete the step 9 because the system doesn't let me put the modified kext file back to its previous position which is /System/Library/Extensions/AMD9500Controller.kext/Contents/MacOS.
edit: Solved the problem, had to disable SIP first.
