Dell Latitude E6400 Laptop - Performance
(Page 4 of 4 )
The E6400 performs incredibly well, both for business functions and some typical laptop functions alike. The base 2.26Hz processor with 3MB of L2 Cache will suffice for most users, especially if your work day consists of email, spreadsheets and Microsoft Office applications. Those looking for more performance should skip over the 2.4GHz option to the T9400 ($190), which offers 6MB of L2 cache and has a clock speed of 2.53GHz. There's more than enough power, however, to accomplish typical work tasks.
The E6400 was configured with a battery-efficient processor plus an 85-Wh battery for one reason: excellent battery life. Dell’s new E6400’s battery will pretty much last for what equates to a cross-country flight. If you opt for integrated graphics instead of the nVidia Quadro chipset, battery life could potentially top seven hours.
Intel’s GMA 4500MHD integrated graphics is standard and is much improved over previous integrated solutions. There’s only a single dedicated solution, the NVIDIA S 160M, which adds $70 to your purchase price. Dell does offer the Intel Core 2 Duo T9600 for $390, but only those that need to squeeze every ounce of performance out of theirE6400should consider it. As usual, there’s a steep premium for ordering the top of the line, and relatively short-run, processor.

Conclusion
Dell’s new Latitude E6400 is ideal for working professionals in search of a business-oriented laptop that can take care of all of their work needs. That being said, it’s not the best choice for someone looking for a laptop that can be used for entertainment purposes. This is definitely not a gaming laptop, nor is it specifically designed for elaborate graphics. That’s okay though, and it’s not a reflection of the machine’s features or performance; some laptops are just better suited for certain things and it should come as no surprise that Dell’s new Latitude E6400 is best suited for working professionals.
Despite some stiff competition from Lenovo and HP, the Dell Latitude E6400 is a tremendous upgrade over the original Latitude D630. A new metallic look, assorted colors and a retouched interior are signs that design is an important criterion in the corporate world, and there are plenty of features and processing parts from which to choose. The E6400’s competitors have nothing on it performance or features-wise, but if you had to nitpick, consumers may find that other business laptops that perform similarly have the edge from a pricing standpoint. Overall,Dell’s Latitude E6400is a beautiful business creation sure to benefit countless working professionals.
