WinBook Unleashes Hyperthreading Heavyweight
Step aside, Centrino. Continuing the trend toward more powerful notebooks, sometimes at the expense of battery life, WinBook's J4 performs more like a desktop than a laptop. Does this eight-pound powerhouse deliver the goods?Notebook buyers who can live with 1 to 2 hours of battery life are snapping up portables built around Intels desktop PC processors (as opposed to Intels mobile CPUs); this yields fine performance and saves up to $250 in the bargain. One of the first units with the desktop 3.06-GHz Pentium 4 (with HyperThreading) is the WinBook J4 732 3.06 ($3,136 direct). At 8.3 pounds (9.4 with the AC adapter, which you wont want to go far without), the J4 is hefty. But it runs away from notebook competitors and keeps pace with all but the fastest desktop PCs, scoring 26.6 on our Business Winstone suite and an excellent 39.7 on our Multimedia Content Creation Winstone test.
The J4 managed 1 hour 58 minutes on our BatteryMark test; acceptable considering the reduced battery life expectations for this class of machine. Under battery power, the J4 scales back to 2.3 GHz and to 1.5 GHz when the battery charge falls below 15 percent.
