Intel Pentium 4 1.7 GHz

Intel launched the Pentium 4 Willamette on November 20, 2000 at 1.4GHz and 1.5GHz. The CPU that would be next in line was the, even slower, 1.3GHz in early 2001. It wasn't until April 23, 2001 for Intel to release the 1.7GHz version. Finally a CPU that was really (overall) faster than it's predecessor Pentium III and could compete with an Athlon 1400 DDR.
