Rambus forges ahead with next-generation memory

With availability expected sometime next year, QRSL offers memory throughput of 1600Mbps -- twice the bandwidth of the Rambus Signaling Level (RSL) technology found in most RDRAM (Rambus Dynamic Random Access Memory) that is used in PCs today, said Brian Smith, the business development manger for Rambus.

Rather than introduce QRSL directly into the PC market, Smith said the new technology will first appear in systems with smaller configurations, for example, networking processors and consumer products like Sony's PlayStation, which already uses Rambus memory.

Ultimately, QRSL will give Rambus an edge in the mobile PC market, as it consumes less power than SDRAM (synchronous DRAM) or DDR (Double Density Rate) memory, Smith said.

Rambus has experienced a less than calm relationship with Intel since the chip maker made its decision to support Rambus as the preferred memory technology for Pentium III processors. Despite this, Intel officials recently renewed support for Rambus, with plans to make the company's Pentium 4 processors Rambus optimised as well.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
