What is the best config ? More cores (like intel I9 with 2GHz 24 cores) or higher CPU frequency ? (like intel I9 with 4GHz 8 cores)
How about the ram.
It all depends a lot on what you do but RAM usually don't matter a lot, e.g. 32 is far enough. About cores it is pretty simple: if your jobs usually run slow and use only 1 CPU (because lots of filtering), then you better get high frequeny but less cores. Just be aware that Core Ix processors can normally not use the full turbo frequency on all cores at the same time (e.g. only a single core gets the full turbo), this is why XEON processors can deliver more throughput, they can apply the max turbo on all cores at the same time.
If you do lots of h264 preview encoding, think about some nvidia gpu and dig into the hardware encoding topics here

But of course you can also do h264 hardware encoding using the Core IX processors

we need faster and multi thread applications.
You cannot have both at the same time, you can either speed up one single job OR get lots of throughput by sacrificing single job speed.
