TEST RESULTS

The M58p was able to play all the video clips in our test suite with modest CPU usage. The electrical power consumption was a bit higher than expected with Prime95. Idle system power was a modest but not record-breaking 41W at the wall outlet.

Note: Neither Furmark nor ATITool would run properly on this system.

With Prime95 running over 15 minutes, the core temperatures were quite high, and the exhaust air very warm to touch. The power adapater also became quite warm. No errors were recorded, however, so the system stayed stable enough.

CPU-centric performance was speedy, as expected with the Intel E8400 processor. Boot time was quite quick.

It's interesting to compare our power conusmption results with Lenovo's data. Two major difference exisit in Lenovoi's test data and ours: Lenovo does not specify the load used to determine maximum power, and the system configuration may not be identical to our sample.


Lenovo's specs indicate lower power draw across the board, except when turned off.

COMPARED TO...

We have very few products that are close comparatives to the M58p. Business PCs are not our usual stock and trade; however, there are two small systems we tested recently. The Dell Studio Hybrid is geared more to the consumer market and uses notebook components. Our DIY mini-ITX System is a small desktop PC an enthusiast could build from retail components. Both would normally be positioned on the desk close to the user.

Dell Studio Hybrid Price: ~$800
Comparative mini-ITX System: Price: ~$700

Note that the mini-ITX system was not actually built into the Thermaltake Lanbox, which is a large shoebox style SFF case. The components were put together on an open test bench platform for actual testing. The case was included in the component list to make a complete system.

This is not to suggest that a breadbox style DIY PC or the Dell Studio Hybrid are directly competitive with the Lenovo M58p. Neither of these PCs are specifically for business, and they lack the management features that would be useful to IT managers. However, they are small, relatively energy efficient PCs recently reviewed by SPCR.

*Boot - time from start button to when the round Vista logo appears

Not surprisingly, the Lenovo is substantially quicker than either of our two comparatives. It has the fastest clocked CPU, and the fastest hard drive; the others employed slower 5400rpm laptop drives. It also draws more power, but because it is quicker, the total power consumed in the completion of each task is a bit lower. For example, the NOD32 benchmark required 3.23 kWh on the Lenovo, a bit less than the 3.34 kWh on the Dell or 3.9875 kWh on the E7200 system.
