Transistor Count

According to the text, since 1971 the number of transistors on a chip has increased from 2,300 to 167 million in 2006. By 2011, the transistor count had further increased to 2.6 billion, a 1,130,434x increase from 1971. The clock frequency has also continued to rise, if a bit slower since 2006. At the time, it was around 2.4GHz, a 3k multiple of the speed in 1971 of 750KHz. Now the high end clock speed of a processor is in the 3.3GHz range.

Evolution of Intel Processors

2010 Core i7 Gulftown 3.2 GHz, 1.17B transistors One of the new 32 nm processors
2011 Core i7 Sandy Bridge E 3.2-3.3 GHz, 32 KB L1 cache per core, 256 KB L2 cache, 20 MB L3 cache, 2.27B transistors Up to 8 cores

Cores

The amount of cores on a chip has continued to increase since 2006. By 2011, Intel and IBM were producing 8-core processors. For servers, AMD was producing up to 16-core processors.

Cluster Computers

The '90s saw a rise of cluster computers, or distributed super computers. This movement has continued to the present, and in 2011 the fastest super computer was Japan's K Computer, a cluster computer.

The K computer contains 88,128 nodes and can perform 10.51 petaflops, making it 4 times as fast as the previous record holder. It does this at a computing efficiency of 93%.

One of the newer innovations in cluster computers is high-availability. These types of clusters operate with redundant nodes to minimize downtime when components fail. Such a system uses automated load-balancing algorithms to route traffic when a node fails.

Chip Multi-Processors

As the diminishing returns and power inefficiencies of ILP progressed, manufacturers began to turn towards chip multi-processors (i.e. multicore architectures).
