Very interesting observation.
When INTEL launched it dual core pentium D, there were 3 partners, DELL, Alienware and VelocityMicro, no other guys are in the party. Until today, HP, Lenovo, Gateway, etc etc hasn't shown interest in INTEL dual core.

Today, AMD launched its dual core chip for PC, the athlon 64 x2, everyone except DELL and INTEL are celebrating.

what's going on?

just read the news:

The AMD Athlon 64 X2 dual-core processor will be supported by leading OEMs including Acer, Alienware, HP and Lenovo, as well as more than 40 leading system-builder partners worldwide.

Partners including Alienware and HP are among the leading manufacturers planning to offer AMD Athlon 64 X2 dual-core processor-based systems.

"Alienware demands the latest and most powerful technology for its systems, and the AMD Athlon 64 X2 dual-core processor easily fits this stringent criteria by providing remarkable performance enhancements for digital media, content creation and multi-tasking," said Frank Azor, Senior Vice President and General Manager for Alienware Worldwide Product Group, Alienware Corporation. "Alienware is excited to be working with AMD to put this ground-breaking technology in the hands of our global customer base."

"HP is always looking for opportunities to deliver leading-edge technologies to our customers that will dramatically improve their computing experience," said John Romano, Senior Vice President, Consumer PC Global Business Unit, HP. "The AMD Athlon 64 X2 dual-core processor running on HP systems will offer users the ability to enjoy and create with their digital content, work on multiple demanding tasks at once, as well as run background applications -- all with a smooth operation of each task."

VelocityMicro is not mentioned in AMD's release, but issued its own press:

And, a host of MB vendors:

To promote a broad selection of dual-core AMD64 technology-based motherboards, AMD has partnered with ABIT, Albatron, AOpen, Arima, Asrock, ASUSTeK Computer Inc., Biostar Group, Chaintech, DFI, Elitegroup Computer Systems (ECS), Epox, FIC, Foxconn, GIGABYTE, IWILL, MSI, Quanta, Sapphire, Shuttle, Soltek, Supermicro Computer, Inc. and Tyan Computer Corporation.

Industry Support:

"Dual-core technology has not only impacted processor micro-architecture design going forward, it can hold incredible implications in the evolution of computing performance and impact on the world at large," stated Danny Hsu, vice president of sales and marketing, Tyan Computer Corporation. "Through the complete implementation of AMD's dual-core infrastructure into Tyan's product lines, our current and future customers can experience new levels of multi-tasking and multi-user performance previously unavailable to them -- another powerful example of how Tyan enables its customers to gain technology leadership."

"Our work with AMD is a testament to our joint innovation that delivers dual-core processing to our customers so they can achieve higher performance-per-watt in server and workstation environments," said Rover Chen, product marketing director, IWILL Corporation. "Because AMD64 processors were engineered from the ground up for multi-core technology, dual-core AMD64 processors directly connect two cores on a single die for easy implementation that can improve overall system performance and efficiency."

"Along with AMD, we are celebrating the innovation that ultimately offers our customers and users incredible freedom of choice," said LC Tsai, chief technology officer, Arima Computer Corp. "AMD's multi-core approach can provide improved performance for computers running multiple applications, and a simplified overall computing infrastructure that helps save money for our customers."

"AMD64 dual-core processors are designed to deliver the amazing performance of a multi-core processor with the same socket infrastructure as single-core AMD64 939- and 940-pin processors," said Joe Hsieh, director, ASUS Motherboard Business, ASUSTeK Computer, Inc. "For us, this represents a significant improvement that simplifies any engineering updates that would otherwise be necessary."

"GIGABYTE is very pleased to be working with AMD on this exciting dual-core technology," said Richard Ma, executive vice president, GIGABYTE. "Due to AMD's ingenious dual-core design, systems builders will have readily-available parts to build their branded products without disruption, and end-users will see dramatically improved performance."

"AMD dual-core technology is a natural extension of AMD64 technology with Direct Connect Architecture because it connects two cores on a single die," said Daniel Wang, channel business development sales vice president of MSI Computer Corp. "This inventive technology can offer superior performance for compute-intensive applications and multi-threaded environments."

"Supermicro is really excited to be collaborating with AMD on dual-core technology," said Dr. Tau Leng, director of technical marketing, Supermicro Computer, Inc. "Along with AMD, we are committed to bringing to market the highest performing motherboard solutions that support x86-based, 64-bit dual-core processors."
