ew Microprocessor Options
Dell now offers the Dell OptiPlex Gs and Gs+ systems
with 166 or 200 megahertz (MHz) Intel®Pentium®
microprocessors with MMX™technology.
The Pentium microprocessor with MMX technology is
specifically designed to handle complex multimedia and
communications software. This microprocessor includes
new instructions and data types as well as a technique
called Single Instruction, Multiple Data (SIMD) that
allows the microprocessor to process multiple data ele-
ments in parallel, thereby improving overall system
performance. The Pentium microprocessor with MMX
technology has twice the internal cache memory (32 kilo-
bytes [KB]) as the standard Pentium microprocessor.
These new Dell OptiPlex Gs and Gs+ systems have the
same features as the previous Dell OptiPlex Gs and Gs+
systems except for the Pentium microprocessors with
MMX technology. The following systems are available:
•The Dell OptiPlex Gs and Gs+ 166 system uses a
Pentium microprocessor with MMX technology that
has an internal speed of 166 MHz and an external
speed of 66 MHz.
•The Dell OptiPlex Gs and Gs+ 200 system uses a
Pentium microprocessor with MMX technology that
has an internal speed of 200 MHz and an external
speed of 66 MHz.
The microprocessor-speed jumper settings on the system
board are the same for the Pentium microprocessors with
MMX technology as for the standard Pentium
microprocessors.
Current application programs not designed specifically
for MMX technology should have a small improvement
in performance when run on Dell OptiPlex Gs and Gs+
systems with a Pentium microprocessor with MMX tech-
nology. Software written specifically to take advantage of
MMX technology (usually labeled “Designed for Intel
MMX”) shows greater performance improvement,
depending on the type of application program.

than the OptiPlex GXiand OptiPlex Gs/Gs+
systems.
