HP ProBook 4425s, 6455b, 6555b now with AMD Phenom; 6450b and 6550b get Intel Core CPUs

While HP made no major design changes to its ProBook line, the company now offers AMD processors on a number of the systems, giving small business customers an even wider range of options to choose from. According to HP, the Phenom II Dual-Core N620 is up to 69 percent faster than the previous generation of AMD processors, and ATI Mobility Radeon 4250 GPUs means that these notebooks will have a little more power than their integrated Intel GPU counterparts.

Of course, all will have HP's wealth of small-business features, including: HP DayStarter, which displays the day's calendar as the machine boots up; QuickWeb, which  lets you surf the net in an Instant-On operating system. Security features include HP ProtectTools, TPM 1.2 security, HP Spare Key, Drive Encryption, and File Sanitizer. Other options include LoJack Pro, a fingerprint reader, and a smart card reader.

The notebooks also come with 3, 6, and 9-cell battery options.
