Sun Microsystems will announce today a new microprocessor
that it boasts to be “the world’s fastest.” The new processor, officially
termed UltraSPARC T2, is the successor to the company’s UltraSPARC T1 – with several
improvements and architectural changes.
The UltraSPARC T2, formerly codenamed Niagara 2, is an
eight-core, 64-thread microprocessor that will reach the server market later
this year. The new chip includes a 4MB L2 cache, two on-chip 10 Gbyte Ethernet
ports, and each core pipeline will have its own integrated FPU.
According to Sun, the new UltraSPARC T2 processor offers
twice as much performance per watt was the UltraSPARC T1 and 10 times the
floating point computational power.
The new chip is also designed to excel at virtualization.
The UltraSPARC T2’s ability to run up to 64 applications simultaneously on a
single processor is an attractive feature for IT departments looking to
simplify their data centers.
"The combination of Solaris and UltraSparc is a very
powerful virtualization platform," said
Fadi Azhari, director of marketing for Sun Microelectronics. "We
believe it's unequal in the industry."
Sun has also kept an eye on processor efficiency. The new
chip is to consume less than two watts per thread, adding up to around 120 to
130 watts for the entire processor. For the basis of comparison, the a
quad-core Intel Xeon processor requires 30 watts per thread.
Although the UltraSPARC T2 will definitely power many of Sun’s
servers later this year, the company has many other plans for the chip’s
applications. Different versions of the chip, perhaps with fewer cores or lower
power consumption, may be usable in networking hardware, set-top boxes, or even
"We don't want to limit ourselves to the server market.
The server market won't grow nearly as fast as the storage or networking
market," Jonathan Schwartz, Sun's CEO, said
in an interview. "While we are making them, we might as well make them
general purpose enough to sell them to the broader market."
The full-featured chip is expected to cost below $1,000,
though scaled-down versions will cost less for more simple applications. Schwartz
said that the company is already speaking to potential network and storage
partners on adoption of the UltraSPARC T2.
"Sun is entering the merchant silicon business and by
that we're going to be chasing the commodity volume markets which are not
simply limited to the market place for server computers," added
quote: SANTA CLARA, Calif. August 7, 2007 Sun Microsystems, Inc., (NASDAQ: SUNW) today announced the world's fastest commodity microprocessor, the UltraSPARC T2, as the cornerstone of its merchant portfolio of microelectronics. Available for sale separate from Sun's own systems, this new processor is the industry's first volume processor with eight cores and eight threads per core. Formerly known as the "Niagara 2" project, the UltraSPARC T2's world-record performance raises the bar on commodity processors while boasting the industry's highest energy efficiency per thread. With each thread capable of running its own operating system, the chip delivers a whopping 64-way system on a single chip. Sun will provide the UltraSPARC T2 processor design to the free and open source community via the GPL license.
