PC specs priority to improve emulation?

So, i just want to upgrade my PC, and having a good machine for decent emulation is one of the reasons i'd like to upgrade. But what do i actually need mostly? Much RAM, a good GPU, or a CPU? If i need a top-tier CPU, which spec in priority? Number of cores, Processor frequensy, CPU-techologies? And what about AMD/Intel specific CPU/GPU? does RPCS3 work good on both brands, or there're some issues?

Or there're no specific requirements, and i have to upgrade just anything?

CPU. At the very minimum, a quad/hexa core from Haswell (4th gen) or up. But note that RPCS3 is probably the only emulator that multithreads this much. Other emulators tend to rely on single core performance mostly.
GPU either NVIDIA or AMD. No Intel, as their iGPUs and drivers are bad.
For RAM, 8GB or up.

For decent results i had recommend at least Ryzen 5 or a haswell i7.
RX 460
8GB RAM

And now that AMD Threadripper is coming,
It's 16 cores would work best for RPCS3,
And it has a decent single core performance too.
Very cheap for the 16 cores,1000$ price tag.

Here's my specs:

Intel Skylake i7 6700
16 GB of RAM
NVIDIA GTX 1070

So far, I got 30 FPS on Demon's Souls with a few drops and random crashes, but as the emulator evolves, I know it will improve.

I remember reading at PCSX2 forums that AMD processors as opposed to Intel, were not suited for emulation because they were made for PC gaming. While Intel CPUs were also made for scientific calculations.

Hence why for high end system requirement emulation, Intel CPUs were usually better. Eg a cheap i3 would have double the performance of a top end AMD on PCSX2.

Is this no longer the case with RCPS3 and is there a parity between Intel and AMD?

They probably referred to the outdated bulldozer.

Ryzen is fine for emulation. Besides, it's cheaper.

RPCS3, like a real PS3, can run a lot of threads at the same time, but something with 16 cores is too much.

Ryzen or i7 is fine, 6+ core Ryzen or Intel is even better in some cases.

I was gonna post a new topic but maybe I can have help with this quick question.

Should I be turning off hyperthreading for smoother emulation?

Intel Core i7 4820K for reference.

nope.
