Advanced Micro Devices admitted that not only did it take quite a while to deliver its quad-core processors onto the market, but when the world"s second largest maker of x86 CPUs finally managed to do so, demand exceeded the chipmaker"s supplies. AMD hopes to improve its quad-core shipments sometime in November. "While our initial production ramp of quad-core Opterons has been slower than anticipated, we expect quad-core Opteron will be widely available by the middle of this quarter; and, we expect to ship hundreds of thousands of quad-core processors this quarter into the server and desktop segments," said Dirk Meyer, chief operating officer of AMD.
