The OptiPlex E1 computer incorporates the Intel Celeron microprocessor for
improved operating speeds and overall performance. Some of the major
enhancement features of the Celeron microprocessor include internal 16-KB
data and 16-KB instruction caches, internal math coprocessor, and the MMX
™
instruction set for high performance in complex multimedia and communica-
tions environments. This microprocessor also uses a technique called single
instruction, multiple data (SIMD), which permits processing data elements in
parallel for additional system performance enhancement.
The microprocessor is physically located in a single-edge processor package
(SEPP) cartridge/heat sink assembly on the system board for ease of upgrad-
ing when faster processors are available. Contact Dell Computer Corporation
