It's too soon to say. There's still variants Meltdown/Spectre that aren't fixed yet. The other guy was correct that it probably depends on your workload, but in a couple months after all the dust has settled on this and we have a comprehensive review, my guess is yes AMD is going to take a commanding lead.
Spectre affects every modern CPU, and performance impact will be marginal.
Meltdown affects Intel-only, and the performance impact will be significant. Here's Fortnight's preliminary server results[0].
Once everything[1] is patched up it's just going to get worse for Intel. Ryzen was already fast though and had superior SMT (Hyperthreading) efficiency than Intel prior to this bug (~10%). This is going to take a serious toll on Intel's single-threaded performance advantage (~10% from IPC, 25% clock frequency advantage).
My advice is to stick with Ryzen/Threadripper/Epyc.
