At the Intel Developer Forum in Tokyo, Intel CTO Pat Gelsinger stated that by 2010 Intel CPUs will run at up to 15GHz. These processors will contain a billion transistors. Didn't Intel claim at the most recent Intel Developer Forum that they would put 10 billion transistors on a chip by 2010? At that time, PDAs may run at up to 5GHz. Intel now has stated that the upcoming Prescott processor will scale to 5GHz, and that the successor chip should scale to 6GHz. Presumably, both chips would be based on the modified Pentium 4 core introduced in 2000. The question with the 15GHz microprocessor is what the Instructions Per Clock (IPC) will be. The IPC went down from the Pentium III to the P4. If the IPC stays the same, then Intel's chips would need to be running about 48GHz by 2010 to maintain the Moore's Law scaling type of performance increases we are used to. So, we must assume that Intel is going to use various architectural enhancements, such as multiprocessing and huge caches, to try and raise the IPC of this processor.
