AMD's Athlon 1400 and Duron 950

Introduction

This is a picture of AMD's new C-Athlon 1400 for 133 MHz FSB

The newly released AMD processors don't mark a significant technological step. What we see is an obvious advance in process technology that allowed the release of a C-type (133/266 MHz FSB) Athlon processor that runs at a 5% higher clock than its predecessor Athlon 1333 , a B-type (100/200 MHz FSB) Athlon that comes with a 7.6 % clock rate increase over Athlon 1300, and a Duron processor with an a clock increase of 5.5% over the previous Duron 900 . You can imagine that the performance improvements seen with those moderate clock speed increases won't be too substantial, but we should remember that clock speed increases in the traditional x86-processor business are done little by little. Only the C-Athlon 1400 seems more like a marketing product than anything else. While the previous C-Athlon 1333 was launched with a 133 MHz and thus 11% core clock increase over the previous C-Athlon 1200, the new C-Athlon 1400 comes with only 66 more MHz than C-Athlon 1333.
