Though the default battery is a 6-cell unit, a 9-cell option is available as well. The base config starts with 1GB RAM, but can be specked up to 8GB. Storage drive options range from a 160GB 5,400 rpm unit on the low end to a 256GB SSD on the high end, with lots of 7,200 rpm and encrypted drive options in between. Both discrete Nvidia NVS 3100M graphics and integrated Intel graphics are available. You can also decide between a 1366 x 768, 1600 x 900, or 1920 x 1080 resolution screen. When configuring your E6510, you can choose between 6 different Core i3, Core i5, and Core i7 CPUs. That gives the E6510 a LAPTOP Green Efficiency rating of 24.4, much better than the category average of 33.1 (lower is better).Ĭlick to enlargeThough our review unit cost a whopping $1,854, base configurations of the Dell Latitude E6510 start at just $729. During that charging period, the notebook used an average of 49.8 watts. Both times were much much quicker than the category averages of 1:34 and 2:23. When charging, the Latitude E6510 took 1 hour and 23 minutes to reach 80-percent of capacity and a full 2 hours and 6 minutes to reach full charge. The 15-foot score was much better than the HP EliteBook 8440p(31.9 / 24.6 Mbps). The notebook's Intel Centrino 6200 802.11n radio produced strong transfer rates of 39.9 and 21.1 Mbps at distances of 15 and 50 feet from the router respectively. However, as we mentioned above, the 9-cell battery adds nearly a pound of weight over its 6-cell counterpart. That time is way longer than the the 3 hour and 48-minute category average and the 2 hours and 6 minutes turned in by the Toshiba Tecra A11.
