Embedded defense applications such as radar, EO/IR and SIGINT along with certain commercial applications are facing an increasing onslaught of data. As these sensor technologies advance, so does the need to process the growing data streams. Fortunately, processing power is also increasing with each new generation of chipsets. To help understand the performance trade-offs and benefits among different processors, Mercury Computer Systems continually evaluates new processors. This paper addresses our recent tests comparing Intel® mobile-class versus server-class processors.
