Shipping-based servers could be a boon for Sun, which is seeking to keep its Sparc family of processors competitive but which has had trouble bringing new processors to market on schedule. But advancing Niagara's schedule would come at the expense of slowing down a more conventional processor, the UltraSparc IIIi+.
"We may choose to release Niagara before the IIIi+," Andy Ingram, vice president of marketing for Sun's Sparc-based servers, said in a Wednesday interview. "We think bringing Niagara to market sooner has a higher value to us and our customers."
Boosting Niagara would boost Sun, said Insight64 analyst Nathan Brookwood. "If they could accelerate Niagara--even by a few months into this calendar year--that would be a phenomenal boost for the company," he said.
For one thing, it would "demonstrate that their execution has been very crisp on this program," and for another, it would let customers evaluate systems, Brookwood said. If Niagara lives up to Sun's claims, it will provide high enough performance and consume little enough electricity that the company could attract new customers to Sparc.
Niagara has been due to arrive in systems in 2006, but Ingram said customers have prototype systems today and an earlier shipment date is possible. "The latest will be early 2006 that we introduce the products," he said. "It's coming in better than any other processor we've ever produced."
Sun's UltraSparc processors are the foundation of a server line that was tremendously popular in the 1990s but has lost share to systems based on Intel's Xeon and IBM's Power family since then. And Intel continues to push its, sold chiefly by Hewlett-Packard.
Sun's response has been threefold. It's aggressively pushing Sparc designs: Niagara, its, and its high-end cousin Rock. The company signed a deal to use Fujitsu's high-end Olympus processor as a replacement for its canceled UltraSparc V. And it's designing based on Advanced Micro Devices' processor, an x86 chip compatible with Intel's Xeon.
Niagara combines eight processing cores on a single piece of silicon, and each core can execute four simultaneous sequences called threads. Sun believes a single Niagara machine will be able to
