It also figures that by the turn of the century the geometries will be 0.1 micron and the transistor count near 100 million.

We're able to increase the transistor count dramatically.

Technical difficulties included the very high transistor counts needed to support the wide instruction words and the large caches.

At some very high transistor count, a future Fusion part could also end up with a raw performance advantage, as well.

The S-cache was removed to reduce the transistor count, which reduced the die size and in turn, cost.

However, the 2010 update has growth slowing at the end of 2013, after which transistor counts and densities are set to double every three years.

The caches are responsible for most of the transistor count and they take up half the die area.

While they could double the transistor count per chip, they would increase power draw about 80%.

You can either reduce your total transistor counts or just use fewer transistors at a time.

While transistor count increases according to Moore's law, overall performance rises only very slowly.
