Dean Hachamovitch finished his demo of Internet Explorer 9 at MIX10 a short while ago. He did a variety of demos for folks to see. Many of these you can try for yourself with the Internet Explorer 9 Platform Preview on the Test Drive site. To do these demos, a variety of Windows PCs were used. I thought I would call out those PCs and their specs.

In the first part of the demo, Dean used an HP xw8400 Workstation. Dean used this PC for demoing interoperability and standards (same markup!). This PC comes with dual Intel Xeon 5150 2.66GHz processors, 4GB of memory, 150GB hard drive, and NVIDIA Quadro FX 1500 graphics.

For the GPU-Powered HTML5 demo Steven Sinofsky, President of the Windows and Windows Live Division, dropped by to take part in showing off IE9 with Dean. Both he and Dean used identical PCs for this demo. The Windows PC they both used was the Dell Studio XPS 1640. The Studio XPS 1640 models they used had a Intel Core 2 Duo P8600 2.4GHz processor, 4GB DDR2 800MHz, ATI Mobility Radeon 3670 graphics, and a 500GB 7200 RPM Drive.

For the HTML5 YouTube and Video Carousel demos, Dean used the Dell Studio 1555. This PC comes with anIntel Dual Core T9600 2.8GHz processor, 4GB of memory, a 250GB 7200 RPM SATA hard drive, and ATI Mobility Radeon HD 4500 graphics.

Special note from me: the Studio 1555 is the very same model I use as my everyday laptop here at work. I refer to it as “The Goat” due to the special design on the back. You can see the design here. Dell’s Design Studio has 200+ designs to choose from for customizing your Dell laptop.

The netbook Dean used was the HP Mini 311 which comes standard with an Intel Atom N270 1.6Ghz processor, 1GB of DDR3 memory, 160GB 7200 RPM SATA hard drive, and NVIDIA Ion graphics.

You’ll notice a few of these PCs use NVIDIA graphics. NVIDIA posted a blog post earlier today about GPU computing and highlights IE9.

The breadth of different types of Windows PCs used in today’s demos of IE9 at MIX10 shows how the browser takes advantage of the power of modern hardware while utilizing fewer resources.
