The Pentium 4 1400-MHz processor suffered a fate similar to its 1300-MHz sibling in the overclocking community. Again, Intel failed to deliver significant performance gains over existing Pentium III and Athlon models in most consumer-oriented software performance testing. Overclocking returns did improve, but the imposed thermal limitation of 70° Celsius mandates installation of a quality cooling solution for those seeking returns in excess of 1700 MHz.
