Dell Latitude XT2 Performance Benchmarks

July 27, 2009 by Kevin O'Brien Reads (167,741)

The Dell Latitude XT2 performed well in our tests, but seemed to be held back by slow hard drive transfer speeds. The XT2 uses one of the newer 1.8″ 5400rpm Toshiba drives, but this didn’t improve anything over other 1.8″ drives we have seen in the past. I think this is the perfect situation where a SSD would provide a huge boost in performance over a standard hard drive. For everyday use the system seemed up to the task and didn’t show too many signs of slowing down. Even when decoding 720P and 1080P video the XT2 worked without a problem. The main areas where it came into play were installing large applications or moving/copying files around, where the main drive ended up being the bottleneck instead of the interface or external drive. 3D gaming was out of the question with the integrated graphics and power efficient SU9400 1.4GHz processor, outside of game like Peggle or Bejeweled.

HDTune measuring hard drive performance:


Heat and Noise
Thermal performance of the XT2 was excellent, staying only mildly warm throughout most of our testing. While under a higher load during our benchmarking, system temperatures crept up slightly, but still stayed within very reasonable levels as shown below. Fan noise was minimal, and I can’t actually recall the fan coming on once during the review. If it was on, it was spinning slow enough that it was barely moving any air. Overall Dell did a very good job cooling the internals of the XT2.
