ASUS Unveils First Motherboards to Feature True USB 3.0 and SATA 6Gb/s Performance

ASUS today announced a range of enhanced motherboard solutions that
deliver true USB 3.0 and SATA 6Gb/s data throughput performance. The
ASUS Xtreme Design P7P55D-E Series motherboard has onboard support
while the ASUS Xtreme Design P7P55D Series utilizes the ASUS U3S6 PCIe
x4 expansion card to deliver the latest USB and SATA data transfer
capabilities. Equipped with the Intel P55 Express chipset, the
P7P55D-E / P7P55D Series supports the latest LGA 1156 socket for Intel
Core i7/Core i5 Processors. Additionally, they also feature exclusive
Hybrid Technology—Hybrid Processor, Hybrid Phase, and Hybrid OS—to give
users intelligent performance enhancement, active cooling, and rapid
online access.

Faster than Ever—True USB 3.0 and SATA 6Gb/s Performance with Bridge Chip

ASUS’ unique expansion bridge design fully unleashes USB 3.0 and SATA
6Gb/s transfer rates for both the P7P55D-E Series and the U3S6
expansion card. This specially-designed onboard IC doubles the
bandwidth of the PCIe interface from Gen 1 to Gen 2, delivering ten
times faster USB 3.0 throughput compared to the previous USB 2.0
standard. Additionally, by eliminating transmission bottlenecks, the
expansion bridge increases hard disk read and write speeds by up to
50%**. Transferring a 20GB HD movie now takes less than 70 seconds,
while a 4MB song requires less than 0.01sec. Similarly, by inserting
the ASUS U3S6 PCIe x4 expansion card into P7P55D Series motherboards,
users can achieve the same rapid throughput with the latest USB 3.0
devices and SATA hard disks.

Hybrid Features for Optimized Performance, Dynamic Cooling, and Rapid Online Access

The ASUS P7P55D-E/P7P55D Series includes new Xtreme Design
innovations—Hybrid Processors, Hybrid Phase Technology and Hybrid OS
for optimized performance and enhanced stability. Hybrid Processors
enable intuitive, real-time overclocking and automatic performance
tuning for users to gain the processing power and speeds associated
with a higher-end CPU. For enhanced stability, the P7P55D-E and P7P55D
Series include the world’s leading Hybrid Phase power feature, which
combines multi-phase power delivery with real-time phase balancing to
improve cooling of active components. Users can also rapidly access
online applications such as Skype, Instant Messaging, and over 1,000
Flash-based games with Express Gate. Additionally, with Windows 7
drivers included, users can conveniently start using Windows 7 and
experience its benefits.
