问题
I have enabled the virtualization in bios setup but when i try to launch the emulator i am getting the error "your cpu doesn't support vt-x or svm"
I have installed Intel haxm too.
回答1:
The VT-x technology as well as the HAXM are unique to Intel processors. In the case of AMD processors, AMD-V is the counterpart in the virtualization tech front. Installation of HAXM in an AMD processor will not have any impact and hence the error "your cpu doesn't support vt-x or svm".
Reference link: http://tools.android.com/tech-docs/emulator
As stated in the link above
For best performance with Android Emulator 2.0, your system should meet the following specifications: Windows: Intel® processor with support for Intel® VT-x, Intel® EM64T (Intel® 64), and Execute Disable (XD) Bit functionality. AMD and Intel Atom processors do not support VT-x virtual machine acceleration. Linux: Intel® processor with support for Intel® VT-x, Intel® EM64T (Intel® 64), and Execute Disable (XD) Bit functionality or AMD processors with support for AMD Virtualization™ (AMD-V™) 64-bit Operating Systems.
I would suggest to use an ARM image for the emulator instead of an Intel image. This would not require the use of HAXM nor VT-x.

I am using AMD RYZEN 3400G. Got the same issue and i fixed it in a very easy manner.
You have to enable Windows Hypervisor Platform
Go to Control Panel> Programs > Turn Windows features on or off and check the Windows Hypervisor Platform. And yes don't install HAXM.
EDIT : 27th Aug 2019
Only install the emulator image which is stable (or one version behind). For now use Android P image not Q, since I had a problem where Android Q image was not working with HyperV & only looking to install HAXM (which we know is not possible since it is not Intel)
Note : The image must not be installing HAXM along with it, otherwise it won't work.

I've been trying to track this down myself for a while (very similar setup, but Windows 10), and haven't seen anyone offering a solution beyond "You know HAXM's just for Intel, right?" either. The best info I've found so far is that the "Individual" edition of Genymotion (free for personal use) seems to be the best bet for emulation on AMD chips, and, almost hidden, a mention in the official docs that suggests Android Studio only works with SVM on Linux. I'm not even sure I'm reading the latter right, given the complete lack of references elsewhere to what should be an important fact, but it could be why that error is showing up – though if that's the case, it's definitely poorly worded.
