My next CPU in few years probably still will be Intel. I need fastest one-core performance in the world and Intel can provide me 5+ GHz and best IPC. I want honest multi-core CPU, not NUMA and Intel will give me 8 honest cores. Meltdown fixes should be in hardware by then, so performance won't be affected and if it is, I'll disable those fixes, I don't need them anyway. But CPU after that might very well be AMD.
