“When you’re comparing two of the best CPUs, the first spec that comes to mind is clock speed. It quite literally represents how fast the CPU can churn through clock cycles, and naturally, you’d assume a higher clock speed means higher performance. Today, however, clock speed doesn’t say much. It can still represent performance differences between two CPUs, but when choosing a processor for your rig, there are several other considerations you should keep in mind.”
So true as a CPU has multiple cores as well as threads, cache, etc that all work together. One CPU clock speed versus another does really not mean much. Way back in the day we had single and dual-core processors where it was perhaps a bit more meaningful.
I also look at CPU benchmarks, but then also compare both single processor and multiprocessor benchmarks. Certainly for gaming and video editing, multicore processing is important (well and along with your GPU of course).
