As the launch of Windows 8 draws closer with every passing day, more detailed specifications on offerings by OEMs are being released or leaked out.

While most OEMs are still mum to most press inquiries, The Wall Street Journal is reporting that Qualcomm chips will power offerings from both Dell and Samsung. Dell’s offering will be a notebook that converts to a tablet; no details on what Samsung is planning are available at this time.

While no OEM has gave concrete reasons for not using Qualcomm, which is known for its robust Snapdragon line of mobile chips, off the record speculation points to supply issues from Qualcomm’s fabrication source.

For Qualcomm, this is likely a sigh of relief as the company has had a challenging experience to date with Windows RT. HP initially had Qualcomm lined up as a chip supplier, but abandoned those plans to instead offer tablets running the x86 version of Windows 8 powered by ARM chips. Microsoft also gave the company a snub when it chose NVIDIA for its Surface tablet.

In a Monday blog post Mike Angiulo, the vice president of Microsoft’s Ecosystem and Planning team, described how important collaboration between Microsoft at OEMs is in a Monday blog post.

“Our engineering collaboration on these Windows RT PCs has been strong, collaborating with the PC manufacturers, Silicon partners, and Operators to focus on hardware, software and services integration,” Mr. Angiulo wrote. “Each respective partner was committed to sharing early iterations of their products, whether it was a SoC bring-up board, early builds of Windows RT, firmware and drivers, or hundreds of pre-release PC hardware samples (such as the ones featured in earlier demonstrations and videos).”

“Product designs were informed and revised by our collective efforts through development and testing. As a result, all of these Windows RT PCs will have consistent fast and fluid touch interactions, long battery life, connected standby, and are beautiful, thin, and light designs. All of these are designed to make the most of the capabilities of Windows RT.”

Toshiba is a notable exception to the Windows RT OEM list. The company announced Tuesday morning that it was instead building Windows 8 tablets with Intel and AMD chips because it claims component delays would “make a timely launch impossible.”

“We will continue to look into the possibility of Windows RT products in the future while monitoring market conditions,” a Toshiba spokesperson said.
