[. . . ] We put every one of our Pentium® and Celeron® processors through a rigorous battery of tests during the design and manufacturing processes. To verify that the new chip will correctly run the software written for Intel Architecture processors, a team of Intel engineers is dedicated to compatibility testing. In a state-of-art lab, this group runs an extensive set of operating systems, applications, network tests and stress tests repeatedly to ensure that the processor is compatible with representative software. Just as importantly, we work with hardware and software companies in the computer industry to ensure that our processors are compatible with their products. [. . . ]
