All Lenovo ThinkStation workstations share common features that showcase Lenovo's dedication to quality, including quiet acoustics, a cool thermal design, RAID standard, back-lit front I/Os and tool-less upgrades. However, both the S20 and D20 also feature unique qualities that makes them a great match for your individual needs.
The single-processor Intel Xeon ThinkStation S20 is the ideal mid-range workstation solution. Offering a robust 625W power supply, even the S20 allows for easy upgrades and offers support for two high-end powered graphics adapters. It is ideal for 2D digital content creators and users of mid-range CAD and EDA applications.
The dual-processor Intel Xeon ThinkStation D20 is a computational powerhouse. Offering 12 DIMM slots and RDIMM technology, the D20 supports up to 192GB of blazing-fast DDR3 memory and is perfect for users of memory and CPU-hungry applications like high-end CAD/CAM/ CAE, 3D digital content creation and professional video editing software. The D20 also offers 1394 and SAS support standard, support for NVIDIA's Tesla C1060 GPU computing solution and NVIDIA SL on select Quadro cards, as well as more expandability options than the S Series.
Professional strength.
Computing muscle. The latest Intel® processors, including Intel Xeon® CPUs with Turbo Boost Technology, aren’t just fast, they’re designed for intelligent performance and energy efficiency, automatically adjusting based on your usage needs. To amp up responsiveness, we've made room for as many as 12 DIMM slots on select workstations.
Cutting-edge graphics solutions. Select ThinkStation workstations integrate NVIDIA® Quadro® professional graphics with SLI technology and the Tesla™ high-performance computing solution. The result? A powerful, versatile solution engineered to meet your high-performance graphics and computing demands.
ISV-certified. Lenovo works closely with leading software partners, and ThinkStation workstations have hundreds of independent software vendor (ISV) certifications, ensuring that you have the performance you need to run the world's most demanding applications.
More to see. With support for up to a whopping eight monitors at once, ThinkStation C20 and C20x help you analyze more, create more and earn more—faster.
Less waiting. Lenovo Enhanced Experience for Windows® 7 PCs boast significantly faster boot-up and shutdown times as well as hardware and software innovations to help you work more productively.
