- It is a matter of cost. Most semiconductor processes have yield curves that
- allow fewer parts at higher speeds than slower parts. This causes the higher
- speed parts to be more expensive. Faster parts also need higher cost cache chips
- to exploit the faster CPU. Therefore, faster chips appear first in the higher
- price bands where the volumes are lower too.
-
- In time as the yield curve shifts and tachnology advances, you will see >150MHz
- parts in workstations which are cost contrained and high volume.
