Eurocom’s Core i7 Notebook: Walking The Panther

Power Use, Battery Life, And Efficiency

Unlike many previous-generation gaming notebooks, Eurocom’s D900F Panther and MSI’s GT725-212US are designed to provide at least some functionality away from the wall socket. Thus, we don’t except them to use nearly as much power as a high-end desktop.

The big energy savings for MSI’s GT725 likely comes from its low-voltage Core 2 Quad processor. Eurocom’s D900F saves only around 50W compared to our Core i7 desktop motherboard test configuration.

Eurcom’s battery is rated only 13% greater capacity than MSI’s, yet the difference in run time is far less than the difference in power consumption. Charge times are similarly lengthy for both unit.

In order to assess efficiency we first had to find the average performance difference. It’s not much of a surprise that Eurocom’s Core i7-965 Extreme desktop processor has a much greater affect on performance than its G92-based graphics unit, but we were hoping for more than a 71% average performance increase.

Dividing the combined performance of each system by its average power consumption reveals that the D900F loses 12% in efficiency compared to MSI’s miserly GT725-212US.

    I really don't understand the point of this review. The two products in here are so different from each other.

    Second fastest mobile processor vs second-fastest desktop processor, it shows the weakness of mobile CPUs AND the weakness of the latest notebook GPU's.

    It had to be compared to something...and it's the only notebook platform available with Core i7 so you can forget about that type of comparison.

    The real point of picking the MSI notebook was to compare the HD 4850 to the GTX 280m. None of Tom's Hardware's suppliers were able to deliver an HD 4870 notebook.

  • the brick: 20 volt x 11 ampere is merely 220 watt?

    I'm not that familiar with those kinds of power supply, but isn't that way to low for these kinds of hardware setups?

    Did you look at the power draw numbers on Page 12?

    I think the point of the review is to show how much the Eurocon $5000 model is a waste of money. The MSI model should have been so outclassed in every aspect, yet it managed to be competitive at lower power envelops.
    Just look at the game selection, 2 games based on the same engine that heavily favor nVidia Architecture and 1 that is more processor bound.

    I think the main problem with this review is, that people forget that Laptop's are designed to be portable, you obviously loose some performance. It’s a compromise between battery life and performance.

    These 2 laptop articles today have only made me more and more happy with my Flextronics/Arima W840DI (thats an Alienware M17 for the less informed - I got it barebones though). Coming in at around $2500 now, I have 3870x2, a QX9300 (ES but still latest revision - TY ebay), 4GB DDR3 and 2 320GB 7200RPM hdd's. My system is slightly more capable than the eurocom above for gaming but of course is crushed in the CPU oriented benchmarks (not that mine does badly). Given that I am paying half as much for a smaller and lighter notebook, OK by me.

    Some of the productivity benchmarks are also likely helped by the DF900's RAIDed hdd set up vs the single hdd. Not sure if you forgot about that but I thought it would help to remind people.

    well the m17 (w840di) can do raid as well, albeit, only across 2 drives.

    Eurocom is reputed to lunch big desktop replacement at high cost. The only thing I suppose to be the point on this review, is the hype of the first Core i7 desktop replacement. The worst is the cost of this computer with another g92 derivate whith slighty poor performance. However, you can have 5k$ stover under your hands!
