CNET writes HP and Gateway are offering systems with the AMD Phenom X3 processor:
The Gateway model GT5670 packs an X3 8400 processor (2.1GHz) with 2MB of L3 cache memory, 3GB (PC2-5300 DDR2) of main memory, an NVIDIA GeForce 6150 SE graphics card, and a 320GB Serial ATA II hard disk drive with 8MB cache (7200 rpm). This configuration goes for $549 at Best Buy.
The HP Pavilion a6430f is eerily similar. It also comes with an X3 8400 Phenom, 3GB PC2-5300 DDR2 memory, and NVIDIA GeForce 6150 SE graphics. However, instead of a 320GB hard disk drive, it doubles the capacity with a 640GB drive. This system is priced at $679. HP also offers the Pavilion a6450z series on its Web site with the X3.
The initial Phenom X3 processors will ship as the B2 "stepping" or version. The follow-on versions in the channel will be the B3, said Moorehead. The B3 version fixes the TLB bug, which AMD has said all along is an extremely rare occurrence and affects virtually no one except, possibly, very high-end customers. Any chips designated with a "50" suffix will be a processor that implements the fix in silicon.
