No, the reason people cared about it was because it meant a faster CPU. The reason people cared about clock speed was because for the same chip it meant a faster CPU. But the misconception that simply "higher clock == fast CPU" is so old it's referred to as the "megahertz myth", since it predates gigahertz. For example, on CPU benchmarking PassMark: Pentium 4, 3.0 GHz (fast!) scores: 382 Pentium 4, 3.8 GHz (faster!) scores: 492 Core i7, 2.6 GHz (slow!) scores: 9,992 CPUs are still getting faster.
