Sparc64 VIは期待できそう。

On integer processing--which represents the bulk of server tasks--the
dual-core design of Sparc64 VI gives twice the performance per chip socket
as Sparc64 V, said Aiichiro Inoue, chief scientist in Fujitsu's server group.
And for floating-point processing, which is used in many mathematical
calculations, its performance is 2.5 times that of Sparc64 V.

整数で2倍、浮動小数点で2.5倍なんて素晴らしい!

The Sparc64 chips are at the heart of a Sun-Fujitsu collaboration called
the Advanced Product Line. The servers from that collaboration are now set
to arrive in early 2007, later than initially projected.

APLは結局2007年の始め頃？

Single-thread performance improves, too, by a factor of 1.4 on integer
processing and by a more dramatic factor of 5 on floating-point processing.
Floating-point throughput has been boosted by a factor of 10.

NiagaraのFPが弱すぎたので、5倍になっちゃてんだよね、明らかに。
