Performance and Benchmarks
This AMD-powered HP ProBook 4425s comes equipped with a quad-core Phenom II P920 processor clocked at 1.6GHz. This configuration is used to match, or at least come close the performance of the Core i3 and i5 equipped ProBook models. In terms of overall system performance we were slightly let down, expecting much higher scores than what we recorded. In normal daily use the system performed pretty well once the majority of the HP-included software was uninstalled. The HP “bloatware” caused some performance lag out of the box. Windows boot times and application load times were helped by the speedy 7200RPM hard drive which comes standard.
Compared to ProBooks with Intel processors and Intel integrated graphics, the AMD Phenom II quad-core with its integrated ATI 4250 graphics fell behind in all of our synthetic performance benchmarks. Compared to the ProBook 4520s, which is very similarly configured, it had slower PCMark05, 3DMark06, and wPrime scores. We also noticed it drew more power during each test compared to the larger Intel systems. Even when stacking an AMD quad-core processor against the current generation dual-core Intel processors, it still had trouble keeping up.
