Lenovo has announced two high-end new PC 'Think' workstations which will go head-to-head with similar products from the stable that invented the brand, IBM.

The ThinkStation D10 is a dual-processor system based on the quad-core Intel Xeon 5400 series chip, while the single-processor S10 will use the Intel Core 2 Extreme QX9650. Both are aimed at graphically-intensive applications such as CAD, much the same markets chased by IBM with its IntelliStation Pro range.

Both feature a variety of large hard drives, high-end and multi-graphics cards based on Nvidia chips, dual Gigabit Ethernet and multiple expansion slots. Lenovo claims the systems use highly efficient power supplies, feature advanced cooling, and make extensive use of recycled plastics in the cases.

The systems are the first new line to use the 'Think' branding for five years, and the first launched by Lenovo since the company bought the PC operation from IBM in 2005.

“Lenovo designed the ThinkStation to be the highest performance, highest quality workstation, delivering an unparalled experience for professional users who work in graphically and computationally intensive environments where a standard desktop PC isn’t enough,” said Peter Schrad of Lenovo.

The move also comes in the week Lenovo indicated it planned to remove the IBM tag from its most famous asset, the ThinkPad laptops.

The D10 and S10 come equipped with a range of “ThinkVantage” software utilities, including Rescue and Recovery, the Client Security System, and Ultra Builder. Pricing depends on configuration, and had not been confirmed at the time of publication.
