As a whole, the Pentium 4 has a higher maximum performance than a Pentium III. The Pentium III performs the same as or better than Pentium 4 at the same clock speed, but the Pentium 4 has a higher max clock speed (which the Pentium 4 was designed for).
The AMD K6-III and early Athlon processors are roughly equivalent in speed and performance. Via C7 processors, although released much later, are close in terms of performance to a Pentium III.
