The UltraSPARC IV+ processor features a design that's much improved over the UltraSPARC IV processor—including enhancements to its dual-cores utilizing the latest 90nm process, which enables frequency improvement through smaller transistor sizes.
Chip Multithreaded Technology.
The UltraSPARC IV+ processor uses Chip Multithreaded Technology that supports two simultaneous threads as a result of two independent cores. Operating at 1.5 GHz, the UltraSPARC IV+ offers up to five times the performance of UltraSPARC III servers and up to double increased performance over UltraSPARC IV servers in the same footprint, with no increase in power and cooling requirements.
Mission-critical throughput
Sun's UltraSPARC IV+ processor provides a unique combination of real world application performance and exceptional product quality for mission-critical enterprise, High Performance Technical Computing (HPTC), and other compute-intensive applications.
Core enhancements.
The UltraSPARC IV+ processor features core enhancements optimized to increase application performance.
Sun's UltraSPARC IV+ processor protects customers' investments through the Solaris 100 percent application compatibility guarantee on all previous SPARC implementations.
Painless upgrade.
Sun's UltraSPARC IV+ processor provides a natural upgrade path for midrange and high-end UltraSPARC III and IV processor-based systems by enabling in-chassis upgrades.
Protects your training investment.
The Solaris OS compatibility guarantee protects customers' software and training investments across time and product lines.
Saves money and time.
Customers can take advantage of newer technology without incurring huge upgrade costs—minimizing downtime and costly application migrations.
The UltraSPARC IV+ processor and the Solaris Operating System support a wide range of applications with enterprise-class reliability.
Solid interconnects.
ECC or parity protection on all interconnects results in enterprise class reliability, availability, and serviceability.
Reduction in soft errors.
The new UltraSPARC IV+ processor delivers a 3x reduction in already-low soft error susceptibility, even with a 5x increase in the number of transistors.
