As part of its spring refresh, HP has announced nine new enterprise notebooks, many of which employ AMD processors and graphics technology. The launch includes the HP 425 and 625 as well as the ProBook 4325s, 4425s, 4525s, 6450b, 6550b, 6455b, 6555b, which make use of Phenom II, Turion II, Athlon II, and V-series processors to accommodate a variety of budgets – though there are some Intel chips in the mix.

Measuring 14 and 15.6-inches HP 425 and 625 are the lowest-priced business systems starting at only $549. The ProBook 4325s, 4425s, and 4525s range offers all of the above-mentioned AMD CPUs and HD 4250 or HD 530v graphics. They should begin shipping this month for as low as $619.

The 6450b and 6550b are 14 and 15.6-inch machines also with discrete Mobility Radeon HD 540v graphics, but rely on Intel Core i3, i5 and i7 processors. Pricing has yet to be determined, but they're scheduled for a June release. Finally, the 6455b and 6555b are AMD-based and seems to be the most diverse for small and mid-sized business users. HP claims they're 69% faster with 24% more battery life than their predecessors.

Additionally, the company's Pavilion dm1, dv5, dv6, and dv7, along with the Compaq CQ42/G42 and CQ62/G62 consumer-grade systems are available with dual or quad-core versions of AMD processors. We have to wonder if the emphasis on AMD chips in HP's latest update lends any credence to rumors that Apple is also mulling the underdog's offerings.
