AR COMPARISON OF PERFORMANCE AND BATTERY LIFE ON DELL LATITUDE AND HP PAVILION NOTEBOOK SYSTEMS Workers can be only as productive as their tools allow them to be. On a sluggish system, the most basic office tasks can become exercises in frustration, lowering user productivity and morale. On a notebook system, battery life also factors into the user experience; simply put, longer is better. Principled Technologies ran a set of industry-standard benchmarks to measure system performance and battery life. We tested two Dell notebook systems powered by 2nd generation Intel Core processors, a mid-range Dell Latitude E6420 notebook and a high-end Dell Latitude E6520, and two HP notebooks powered by AMD processors, a mid-range HP Pavilion dm1z and a high-end HP Pavilion dv6z Select Edition. The Intel Core processor-based Dell Latitude systems delivered longer battery life—as much as 62 minutes longer—and higher benchmark scores—as much as 384.5 percent higher—than the corresponding HP Pavilion systems, making Dell a great choice for productivity and user satisfaction in the workplace. MAY 2011 A PRINCIPLED TECHNOLOGIES TEST REPORT Commissioned by Dell Inc. DELL AND INTEL DELIVER PERFORMANCE AND BATTERY LIFE Responsive performance enhances worker productivity. That’s why, when choosing notebook systems for the workplace, it makes sense to purchase systems powerful enough to execute tasks quickly and efficiently. It also makes sense to purchase notebooks that can run for a long time on a single battery charge. We used MobileMark 2007 v1.06 Productivity 2007 to test battery life and SYSmark 2007 Preview v1.06 and MAXON CINEBENCH R10 to test overall system performance. In our tests, the Intel Core processor- based Dell Latitude E6420 notebook and Dell Latitude E6520 delivered considerably better battery life and performance. (Learn more about the systems we tested in Appendix A and more about the testing we conducted in Appendix B.) Figure 1 shows the BAPCo MobileMark 2007 battery life testing results. The Dell Latitude E6420 notebook, with a score of 428 minutes, outperformed the HP Pavilion dm1z notebook’s score of 366 by 16.9 percent, or 62 minutes. The Dell Latitude E6520’s score of 293 minutes was 15.4 percent higher—providing an extra 39 minutes of life—than the HP Pavilion dv6z Select BAPCo MobileMark 2007 1.06 Battery Life Edition’s 254-minute score. 500 428 366 400 293 SYSmark 2007 Preview 300 254 v1.06 measures system 200 100 performance in four workload Minutes 0 scenarios: e-learning, office Dell Latitude HP Pavilion Dell Latitude HP Pavilion E6420 dm1z E6520 dv6z productivity, video creation, and (Intel Core i5) (AMD Dual- (Intel Core i7) Select Edition Core) (AMD 3D modeling.

CINEBENCH plays a scene that makes use of various CPU-intensive features. During the first run, the benchmark uses only one CPU or CPU core to determine a reference value. On computers with multiple CPUs or cores, CINEBENCH runs a second test using all available CPU power. The benchmark produces a single-CPU score for all computers, and a multiple-CPU score for those computers with multiple cores. As Figure 3 shows, the Dell MAXON CINEBENCH R10 Single CPU Latitude E6420 notebook, with a 6,000 5,134 5,258 single-CPU score of 5,134, 4,000 2,071 outperformed the HP Pavilion 2,000 1,156 dm1z notebook by 344.1 percent.
