@Xi Computer is no stranger to making speedy computers, and the Xi PowerGo Duo XT mobile workstation submitted for this roundup is no exception. Based on an Intel Core 2 Duo E6850 processor rated at 3.0 GHz with a 4-MB L2 cache, the system arrived with 2 GB of DDR2 800 MHz RAM installed, although it will accommodate 4 GB when fully populated.  

 

Graphics on the Xi PowerGo Duo XT are handled by the capable NVIDIA Quadro FX 1600M, which features 512 MB of integrated onboard memory. The system, as requested, came with Microsoft Windows XP with Service Pack 2 preinstalled and included NVIDIA drivers v.6.14.11.7433, dated March 5, 2008. This system configuration is almost identical to the one submitted by Polywell, although Polywell elected to use older drivers that didn't provide the level of performance that newer drivers obviously are capable of producing. The display is a 17" wide-aspect ratio glass view panel with WUXGA resolution of 1,920 x 1,200, although the benchmark testing was done at a resolution of 1,280 x 1,024.  

 


The Xi PowerGo Duo XT mobile workstation is big but powerful. It weighs in at 11.8 lb but makes up for its bulk with A+ performance.
 
The Xi PowerGo Duo XT was, at 15.6" x 1.8" x 11.5" (W x H x D), decidedly on the large side and, at 11.8 lb, also on the heavy side. It's not the largest or heaviest mobile workstation I've ever seen, but I would be conscious of its size and weight after carrying it around for a while. The given weight includes the lithium ion battery. The system is relatively quiet in operation and features one FireWire connector, one Bluetooth 2.0, and four USB 2.x connectors.  

With the Cadalyst C2008 benchmark running under AutoCAD 2008, I tested the Xi PowerGo Duo XT in two different configurations. With the AutoCAD 2008 native OpenGL drivers, the C2008 total index score was 223, completed in 93 minutes. With AutoCAD 2008 configured to use the native Direct 3D drivers, the C2008 total index score was 267, and the test ran to completion in 74 minutes. With the Direct 3D drivers, I tested two concurrent sessions of AutoCAD 2008 side by side, with each running a separate version of the C2008 benchmark. The combined C2008 total index score was 551, and the time for completion was 75 minutes.

Next, I ran the MAXBench4 benchmark under Autodesk 3ds Max 2008 with several iterations in three different configurations. With the native OpenGL drivers, the averaged high/low score was 94.39. Using 3ds Max 2008's native Direct3D drivers, the averaged high/low score was 178.98. Finally, with the NVIDIA MAXtreme 10.00.03 accelerated driver, the averaged high/low score was 190.35.

The full SPECviewperf 10 benchmark was run with Xi PowerGo Duo XT, which produced the following results: 39.01 for 3ds max-04, 44.67 for catia-02, 30.65 for ensight-03, 105.07 for maya-02, 39.69 for proe-04, 63.95 for sw-01, 15.26 for tcvis-01, and 13.55 for ugnx-01. These scores, in addition to the AutoCAD and Autodesk 3ds Max scores above, earned the Xi PowerGo Duo XT an A+ for performance.

Battery performance was generally good for the Xi PowerGo Duo XT system, with an idle rundown time of 1 hour, 43 minutes, and an active rundown time of 1 hour, 22 minutes running a continuous loop of the Cadalyst C2008 benchmark under AutoCAD 2008. As is usually the case, the higher the system performance, the shorter the battery life.
