From The Solution:

The UltraSPARC T1 processor enables an era of cool computing at Sun. The combination of high throughput and low power consumption is unprecedented in the industry. The UltraSPARC T1 processor is roughly eight times the UltraSPARC IV processor throughput measured on a number of workloads while consuming 50 percent of the power of a single UltraSPARC IV processor. When compared to offerings from IBM, Intel, and AMD, the UltraSPARC T1 processor has a significant power and performance advantage that translates into a dramatic reduction in total cost of ownership (TCO).

The UltraSPARC T1 processor is the first in a series of processors that employ finegrain multithreading. Subsequent designs will continue to focus on industry leading throughput performance as well as power and performance. The goal is to double throughput performance and hold total power constant. This is accomplished with greater efficiency in pipeline designs, fine granularity clock gating, and advanced circuit techniques.

Competitors who pursue higher performance with the traditional ILP techniques will fall further behind the power and performance curve.
