    Hi people :
    The question I have is in reference to a CPUs Clock Speed vs number of Cores. I'm not sure, in my future build, which Intel CPU to get. I'll be doing a lot of 3D Rendering. So....I'm not sure which facet of the CPU would be of most help. Thanks.......garystan

    You don't say what O/S you're planning to use and that does make a difference. Windows 7 (or lower), for example, will only use 2 cores unless the software specifically uses the additional cores.
    And I disagree with managed; the single thread rating is a measure of what each core is capable of individually and, for most regular duty PC's, that is more important than the overall rating.
    Passmark.com, as a note, is the parent of cpubenchmark and has several hundred million benchmarks at this point. I use it when I am shopping to find the most "bang for the buck".

    The number of cores and threads is more important for rendering benchmarks

    For complex, cpu intensive tasks, the number of cores will make a big difference. Regardless of what was said above, win7 will use as many cores as you have [as long as the program is written to use multicore]
    Next the suggestion to consult benchmarks is a good one.
    I have two personal systems here; an intel 7600k overclocked to 4.5gig and a ryzen 1700X overclocked to 3.9gig. On single core benchmarks, the intel has a slight advantage [not surprising since it is clocked quite a bit higher] On mulitcore benchmarks, the ryzen system blows the intel out of the water. It is like the intel should not even have come to the party. On cinebench cpu benchmark, the ryzen system literally doubles the intel score. On realbench, the ryzen outscores the intel by 35% or so.

    One last caveat. Ryzen is not intel where you can just slap parts together and it works. Ryzen takes careful tuning in the bios in order to achieve the above referenced performance.

    In short, if you are the type of guy who likes to work on stuff, they ryzen is fine. If you just want it to work, go intel however you will have to spend quite a bit more on the processor to get to the level of ryzen multicore performance; at the very least an i7 8700k or an i9.
