Today IBM announced a new line of high-powered QS20 Blade Servers intended for use in seismic research, encryption, digital image rendering and military surveillance applications. Each QS20 will include two nine-cored Cell Processors clocked at 3.2Ghz apiece, which were developed by IBM along with Sony and Toshiba for Sony’s upcoming Playstation 3 console, among other things.
The primary uses that come to mind are medical or hardcore multi-media rendering, so it’s not for those without deep pockets. According to the article, each Cell CPU has 9 cores. 18 cores for a server sounds good!
