Fujitsu is the latest chip maker to introduce a 90-nanometer product with the launch of a faster version of its Sparc64 V processor for enterprise servers.

The processor runs at 1.89GHz, an increase from the 1.35GHz clock speed of the 130-nanometer chip. Fujitsu also added 1Mbyte of Level 2 cache to the processor to bring the total amount to 3Mbytes.
Every few years, chip makers engineer process technology "shrinks", in which manufacturing and design is changed to accommodate smaller transistors. This allows them to place more transistors on an individual chip.
These extra transistors can be used in a number of different ways to improve performance, such as adding instructions, increasing the chip's clock speed, adding new cache or combining those techniques.
Fujitsu plans to use the processor in five PrimePower servers. The PrimePower 650 is an eight-processor server, while the PrimePower 850 and 900 servers can use up to 16 1.89GHz processors. The PrimePower 1500 can be configured with up to 32 1.89GHz processors, and the most powerful server, the PrimePower 2500, features up to 128 processors. The processors used in the 2500 operate at 1.82GHz.
Sun Microsystems will also be able to sell the PrimePower servers following an agreement between the two companies earlier this year.
Sun and Fujitsu will sell each other's Sun Fire and PrimePower products as well as collaborate on a new line of servers known as APL (Advanced Product Line). The APL servers will incorporate Fujitsu's next-generation Sparc64 VI processor.
